How to set form input required attribute in laravel 4

问题

I'm using the laravel framework for a project, and I'm implementing a basic form page, where I require certain values to be required, something that can be done very easily in HTML5.

<input type="text" name="abc" required>

In laravel, without the required attribute, the same would be :

{{ Form::text('abc') }}

How do I incorporate a required attribute in the above statement?

回答1:

Since simply writing ['required'] did not work, I searched online a bit more and found the answer, so I thought I'd share it here.

The third parameter is an array of optional attributes, which, in convention, must be written as:

{{ Form::text('abc','',array('required' => 'required')) }}

Similarly, for a radio button with default selected/checked we have:

{{ Form::radio('abc', 'yes', array('checked' => 'checked')) }}

Check out the API-Docs. The method signature shows that you can provide 3 parameters.

The first one is the name attribute, the second one is the value attribute. Third one is your array with any additional attributes.

So just call your method with:

{{ Form::text('key', 'value', ['required']) }}

And a required attribute will be attached to your input field.

I believe the correct answer is similar to the other post where the third parameter is

array('required' => 'required')

however to get the attribute without any value you can do the following:

array('required' => '')

The input field (for text example), will then look what was necessary in the question.

Laravel Example:

{{ Form::text('title', '', array('tabindex' => '1', 'required' => '')) }}

HTML output:

<input tabindex="1" required name="title" type="text" value="" id="title">

I believe this actually shorthand for required='', just wanted to add this note

Radio required featured works with laravel 5.7 version

@foreach($status_list as $status_key => $status)
  {!! Form::radio('status', $status_key, false, array('id'=>'status_'.$status_key, 'required'=>'required' )); !!}
  {!! Form::label('status_'.$status_key, $status ) !!}
@endforeach

I hope, this will help you also. :)
