The Laravel Flysystem integration provides simple to use drivers for working with local filesystems and Amazon S3. Even better, it's amazingly simple to switch between these storage options as the API remains the same for each system.
Within this file you may configure all of your "disks". Each disk represents a particular storage driver and storage location. Example configurations for each supported driver are included in the configuration file. So, modify the configuration to reflect your storage preferences and credentials. You may configure as many disks as you like, and may even have multiple disks that use the same driver.
The public disk is intended for files that are going to be publicly accessible. This convention will keep your publicly accessible files in one directory that can be easily shared across deployments when using zero down-time deployment systems like Envoyer. Once a file has been stored and the symbolic link has been created, you can create a URL to the files using the asset helper:.
You may configure additional symbolic links in your filesystems configuration file. Each of the configured links will be created when you run the storage:link command:. When using the local driver, all file operations are relative to the root directory defined in your filesystems configuration file.
The public visibility translates to for directories and for files. You can modify the permissions mappings in your filesystems configuration file:. An absolute must for performance is to use a cached adapter. You will need an additional package for this:.
This file contains an example configuration array for an S3 driver. You are free to modify this array with your own S3 configuration and credentials. Laravel's Flysystem integrations works great with FTP; however, a sample configuration is not included with the framework's default filesystems.
If you need to configure a FTP filesystem, you may use the example configuration below:. Laravel's Flysystem integrations works great with SFTP; however, a sample configuration is not included with the framework's default filesystems.
If you need to configure a SFTP filesystem, you may use the example configuration below:.Joleen cronin photography
To enable caching for a given disk, you may add a cache directive to the disk's configuration options. The cache option should be an array of caching options containing the disk name, the expire time in seconds, and the cache prefix :. The Storage facade may be used to interact with any of your configured disks.
For example, you may use the put method on the facade to store an avatar on the default disk. If you call methods on the Storage facade without first calling the disk method, the method call will automatically be passed to the default disk:.
laravel checking if record exists
If your application interacts with multiple disks, you may use the disk method on the Storage facade to work with files on a particular disk:.
The get method may be used to retrieve the contents of a file. The raw string contents of the file will be returned by the method. Remember, all file paths should be specified relative to the "root" location configured for the disk:.
The download method may be used to generate a response that forces the user's browser to download the file at the given path. The download method accepts a file name as the second argument to the method, which will determine the file name that is seen by the user downloading the file.
Finally, you may pass an array of HTTP headers as the third argument to the method:. You may use the url method to get the URL for the given file. If you are using the s3 driver, the fully qualified remote URL will be returned:.Laravel ships with a simple, convenient facility for validating data and retrieving validation error messages via the Validator class.
The first argument passed to the make method is the data under validation. The second argument is the validation rules that should be applied to the data. Multiple rules may be delimited using either a "pipe" character, or as separate elements of an array.
Once a Validator instance has been created, the fails or passes method may be used to perform the validation. You may also access an array of the failed validation rules, without messages. To do so, use the failed method:. The Validator class provides several rules for validating files, such as sizemimesand others. When validating files, you may simply pass them into the validator with your other data.Hindi afsomali
The validator also allows you to attach callbacks to be run after validation is completed. This allows you to easily perform further validation, and even add more error messages to the message collection.
To get started, use the after method on a validator instance:. Of course, manually creating and checking a Validator instance each time you do validation is a headache. Don't worry, you have other options!

This trait provides a single, convenient method for validating incoming HTTP requests. Here's what it looks like:. If validation passes, your code will keep executing normally.Samsung laptop bios problem
This exception is automatically caught and a redirect is generated to the user's previous location. The validation errors are even automatically flashed to the session!
If the incoming request was an AJAX request, no redirect will be generated. If you wish to customize the format of the validation errors that are flashed to the session when validation fails, override the formatValidationErrors on your base controller. For more complex validation scenarios, you may wish to create a "form request".
Form requests are custom request classes that contain validation logic. To create a form request class, use the make:request Artisan CLI command:.
Let's add a few validation rules to the rules method:. So, how are the validation rules executed? All you need to do is type-hint the request on your controller method:. The incoming form request is validated before the controller method is called, meaning you do not need to clutter your controller with any validation logic.
It has already been validated! If validation fails, a redirect response will be generated to send the user back to their previous location. The errors will also be flashed to the session so they are available for display.The incoming request instance will automatically be injected by the service container :.Metropcs device unlock app hack
If your controller method is also expecting input from a route parameter you should list your route parameters after your other dependencies. For example, if your route is defined like so:. The service container will automatically inject the incoming request into the Closure when it is executed:. We will discuss a few of the most important methods below.
The path method returns the request's path information. The is method allows you to verify that the incoming request path matches a given pattern. To retrieve the full URL for the incoming request you may use the url or fullUrl methods. The url method will return the URL without the query string, while the fullUrl method includes the query string:. The method method will return the HTTP verb for the request. If you would like to obtain an instance of a PSR-7 request instead of a Laravel request, you will first need to install a few libraries.
Once you have installed these libraries, you may obtain a PSR-7 request by type-hinting the request interface on your route Closure or controller method:.
These middleware will automatically trim all incoming string fields on the request, as well as convert any empty string fields to null. This allows you to not have to worry about these normalization concerns in your routes and controllers. You may also retrieve all of the input data as an array using the all method:. Regardless of the HTTP verb, the input method may be used to retrieve user input:.
You may pass a default value as the second argument to the input method. This value will be returned if the requested input value is not present on the request:. When working with forms that contain array inputs, use "dot" notation to access the arrays:. You may call the input method without any arguments in order to retrieve all of the input values as an associative array:.
While the input method retrieves values from entire request payload including the query stringthe query method will only retrieve values from the query string:. If the requested query string value data is not present, the second argument to this method will be returned:. You may call the query method without any arguments in order to retrieve all of the query string values as an associative array:.
For example, if one of your application's forms contains a name field, you may access the value of the field like so:.
When using dynamic properties, Laravel will first look for the parameter's value in the request payload. If it is not present, Laravel will search for the field in the route parameters.
You may even use "dot" syntax to dig into JSON arrays:. When dealing with HTML elements like checkboxes, your application may receive "truthy" values that are actually strings. For example, "true" or "on". For convenience, you may use the boolean method to retrieve these values as booleans.3 way switch wiring 1998 lincoln mark viii service repair shop set
The boolean method returns true for 1, "1", true, "true", "on", and "yes". All other values will return false :.Valid iccid
If you need to retrieve a subset of the input data, you may use the only and except methods.Laravel makes interacting with databases extremely simple across a variety of database backends using either raw SQL, the fluent query builderand the Eloquent ORM. Currently, Laravel supports four databases:. In this file you may define all of your database connections, as well as specify which connection should be used by default. Examples for most of the supported database systems are provided in this file.
By default, Laravel's sample environment configuration is ready to use with Laravel Homesteadwhich is a convenient virtual machine for doing Laravel development on your local machine. You are free to modify this configuration as needed for your local database. Typically, database connections are configured using multiple configuration values such as hostdatabaseusernamepasswordetc. Each of these configuration values has its own corresponding environment variable.
This means that when configuring your database connection information on a production server, you need to manage several environment variables.
Some managed database providers such as Heroku provide a single database "URL" that contains all of the connection information for the database in a single string.
An example database URL may look something like the following:. For convenience, Laravel supports these URLs as an alternative to configuring your database with multiple configuration options. Laravel makes this a breeze, and the proper connections will always be used whether you are using raw queries, the query builder, or the Eloquent ORM. Note that three keys have been added to the configuration array: readwrite and sticky. The read and write keys have array values containing a single key: host.
The rest of the database options for the read and write connections will be merged from the main mysql array. You only need to place items in the read and write arrays if you wish to override the values from the main array.
So, in this case, The database credentials, prefix, character set, and all other options in the main mysql array will be shared across both connections. The sticky option is an optional value that can be used to allow the immediate reading of records that have been written to the database during the current request cycle. If the sticky option is enabled and a "write" operation has been performed against the database during the current request cycle, any further "read" operations will use the "write" connection.
This ensures that any data written during the request cycle can be immediately read back from the database during that same request.
It is up to you to decide if this is the desired behavior for your application. When using multiple connections, you may access each connection via the connection method on the DB facade. You may also access the raw, underlying PDO instance using the getPdo method on a connection instance:. Once you have configured your database connection, you may run queries using the DB facade.Laravel provides several different approaches to validate your application's incoming data.
By default, Laravel's base controller class uses a ValidatesRequests trait which provides a convenient method to validate incoming HTTP request with a variety of powerful validation rules. To learn about Laravel's powerful validation features, let's look at a complete example of validating a form and displaying the error messages back to the user.
Of course, the GET route will display a form for the user to create a new blog post, while the POST route will store the new blog post in the database. Next, let's take a look at a simple controller that handles these routes. We'll leave the store method empty for now:.
Now we are ready to fill in our store method with the logic to validate the new blog post. This trait provides a convenient validate method in all of your controllers. The validate method accepts an incoming HTTP request and a set of validation rules. If the validation rules pass, your code will keep executing normally; however, if validation fails, an exception will be thrown and the proper error response will automatically be sent back to the user.
To get a better understanding of the validate method, let's jump back into the store method:. As you can see, we simply pass the incoming HTTP request and desired validation rules into the validate method.
Again, if the validation fails, the proper response will automatically be generated. If the validation passes, our controller will continue executing normally. Sometimes you may wish to stop running validation rules on an attribute after the first validation failure. To do so, assign the bail rule to the attribute:. In this example, if the required rule on the title attribute fails, the unique rule will not be checked.
Rules will be validated in the order they are assigned. If your HTTP request contains "nested" parameters, you may specify them in your validation rules using "dot" syntax:.
So, what if the incoming request parameters do not pass the given validation rules? As mentioned previously, Laravel will automatically redirect the user back to their previous location. In addition, all of the validation errors will automatically be flashed to the session. Again, notice that we did not have to explicitly bind the error messages to the view in our GET route.
This is because Laravel will check for errors in the session data, and automatically bind them to the view if they are available. For more information on working with this object, check out its documentation.
So, in our example, the user will be redirected to our controller's create method when validation fails, allowing us to display the error messages in the view:.
If you wish to customize the format of the validation errors that are flashed to the session when validation fails, override the formatValidationErrors on your base controller. In this example, we used a traditional form to send data to the application. However, many applications use AJAX requests.
When using the validate method during an AJAX request, Laravel will not generate a redirect response. Validating array form input fields doesn't have to be a pain. For example, to validate that each e-mail in a given array input field is unique, you may do the following:. If you do not want to use the ValidatesRequests trait's validate method, you may create a validator instance manually using the Validator facade.
The make method on the facade generates a new validator instance:. The first argument passed to the make method is the data under validation. The second argument is the validation rules that should be applied to the data. After checking if the request failed to pass validation, you may use the withErrors method to flash the error messages to the session.
If you have multiple forms on a single page, you may wish to name the MessageBag of errors, allowing you to retrieve the error messages for a specific form.
Simply pass a name as the second argument to withErrors :.Laravel provides several different approaches to validate your application's incoming data.

If the validation passes, our controller will continue executing normally. Alternatively, validation rules may be specified as arrays of rules instead of a single delimited string:. You may use the validateWithBag method to validate a request and store any error messages within a named error bag :.
Sometimes you may wish to stop running validation rules on an attribute after the first validation failure. To do so, assign the bail rule to the attribute:. In this example, if the unique rule on the title attribute fails, the max rule will not be checked.
Rules will be validated in the order they are assigned. If your HTTP request contains "nested" parameters, you may specify them in your validation rules using "dot" syntax:. So, what if the incoming request parameters do not pass the given validation rules? As mentioned previously, Laravel will automatically redirect the user back to their previous location. In addition, all of the validation errors will automatically be flashed to the session.
Again, notice that we did not have to explicitly bind the error messages to the view in our GET route.Laravel's database query builder provides a convenient, fluent interface to creating and running database queries. It can be used to perform most database operations in your application and works on all supported database systems. There is no need to clean strings being passed as bindings. Therefore, you should never allow user input to dictate the column names referenced by your queries, including "order by" columns, etc.
If you must allow the user to select certain columns to query against, always validate the column names against a white-list of allowed columns. You may use the table method on the DB facade to begin a query. The table method returns a fluent query builder instance for the given table, allowing you to chain more constraints onto the query and then finally get the results using the get method:. You may access each column's value by accessing the column as a property of the object:. If you just need to retrieve a single row from the database table, you may use the first method.
This method will return a single stdClass object:. If you don't even need an entire row, you may extract a single value from a record using the value method. This method will return the value of the column directly:. If you would like to retrieve a Collection containing the values of a single column, you may use the pluck method. In this example, we'll retrieve a Collection of role titles:.
If you need to work with thousands of database records, consider using the chunk method. This method retrieves a small chunk of the results at a time and feeds each chunk into a Closure for processing. This method is very useful for writing Artisan commands that process thousands of records. For example, let's work with the entire users table in chunks of records at a time:. You may stop further chunks from being processed by returning false from the Closure :. If you are updating database records while chunking results, your chunk results could change in unexpected ways.
So, when updating records while chunking, it is always best to use the chunkById method instead. This method will automatically paginate the results based on the record's primary key:. This could potentially result in records not being included in the chunked results. The query builder also provides a variety of aggregate methods such as countmaxminavgand sum.
You may call any of these methods after constructing your query:. Instead of using the count method to determine if any records exist that match your query's constraints, you may use the exists and doesntExist methods:.
You may not always want to select all columns from a database table. Using the select method, you can specify a custom select clause for the query:. If you already have a query builder instance and you wish to add a column to its existing select clause, you may use the addSelect method:. Sometimes you may need to use a raw expression in a query. To create a raw expression, you may use the DB::raw method:.Laravel 5 Unit testing tutorial - database record testing - match record
Instead of using DB::rawyou may also use the following methods to insert a raw expression into various parts of your query. The selectRaw method can be used in place of addSelect DB::raw This method accepts an optional array of bindings as its second argument:.
