Laravel change input value
In laravel, we can get the input value via Input::get('inputname')
. I try to change the value by doing this Input::get('inputname') = "new value";
. But then, I get the error message saying Can't use function return value in write context
.
Is it possible for us change the input value so that when later calling on Input::get('inputname')
will get the new amended value?
Thanks.
Solution 1:
You can use Input::merge()
to replace single items.
Input::merge(['inputname' => 'new value']);
Or use Input::replace()
to replace the entire input array.
Input::replace(['inputname' => 'new value']);
Here's a link to the documentation
Solution 2:
If you're looking to do this in Laravel 5, you can use the merge()
method from the Request
class:
class SomeController extends Controller
{
public function someAction( Request $request ) {
// Split a bunch of email addresses
// submitted from a textarea form input
// into an array, and replace the input email
// with this array, instead of the original string.
if ( !empty( $request->input( 'emails' ) ) ) {
$emails = $request->input( 'emails' );
$emails = preg_replace( '/\s+/m', ',', $emails );
$emails = explode( ',', $emails );
// THIS IS KEY!
// Replacing the old input string with
// with an array of emails.
$request->merge( array( 'emails' => $emails ) );
}
// Some default validation rules.
$rules = array();
// Create validator object.
$validator = Validator::make( $request->all(), $rules );
// Validation rules for each email in the array.
$validator->each( 'emails', ['required', 'email', 'min: 6', 'max: 254'] );
if ( $validator->fails() ) {
return back()->withErrors($validator)->withInput();
} else {
// Input validated successfully, proceed further.
}
}
}
