Input

• Basic Input
• Old Input
• Files

Please note that both Input and Request do NOT sanitize your data, it is up to you to do that.

Basic Input

You may access all user input with a few simple methods. You do not need to worry about the HTTP verb used for the request, as input is accessed in the same way for all verbs.

Retrieving An Input Value

$name = Input::get(‘name‘);

Retrieving A Default Value If The Input Value Is Absent

$name = Input::get(‘name‘, ‘Sally‘);

Determining If An Input Value Is Present

if (Input::has(‘name‘))
{
    //
}

Getting All Input For The Request

$input = Input::all();

Getting Only Some Of The Request Input

$input = Input::only(‘username‘, ‘password‘);

$input = Input::except(‘credit_card‘);

When working on forms with "array" inputs, you may use dot notation to access the arrays:

$input = Input::get(‘products.0.name‘);

Note: Some JavaScript libraries such as Backbone may send input to the application as JSON. You may access this data via Input::get like normal.

Old Input

You may need to keep input from one request until the next request. For example, you may need to re-populate a form after checking it for validation errors.

Flashing Input To The Session

Input::flash();

Flashing Only Some Input To The Session

Input::flashOnly(‘username‘, ‘email‘);

Input::flashExcept(‘password‘);

Since you often will want to flash input in association with a redirect to the previous page, you may easily chain input flashing onto a redirect.

return Redirect::to(‘form‘)->withInput();

return Redirect::to(‘form‘)->withInput(Input::except(‘password‘));

Note: You may flash other data across requests using the Session class.

Retrieving Old Data

Input::old(‘username‘);

Files

Retrieving An Uploaded File

$file = Input::file(‘photo‘);

Determining If A File Was Uploaded

if (Input::hasFile(‘photo‘))
{
    //
}

The object returned by the file method is an instance of the Symfony\Component\HttpFoundation\File\UploadedFile class, which extends the PHP SplFileInfo class and provides a variety of methods for interacting with the file.

Determining If An Uploaded File Is Valid

if (Input::file(‘photo‘)->isValid())
{
    //
}

Moving An Uploaded File

Input::file(‘photo‘)->move($destinationPath);

Input::file(‘photo‘)->move($destinationPath, $fileName);

Retrieving The Path To An Uploaded File

$path = Input::file(‘photo‘)->getRealPath();

Retrieving The Original Name Of An Uploaded File

$name = Input::file(‘photo‘)->getClientOriginalName();

Retrieving The Extension Of An Uploaded File

$extension = Input::file(‘photo‘)->getClientOriginalExtension();

Retrieving The Size Of An Uploaded File

$size = Input::file(‘photo‘)->getSize();

Retrieving The MIME Type Of An Uploaded File

$mime = Input::file(‘photo‘)->getMimeType();
