htmlentities() expects parameter 1 to be string, array given

问题

I'm trying to add a class to a laravel form. The array is being passed as the third argument, as required, but I get the above error.

{{ Form::input('text', $variable->name, array('class' => 'form-control')) }}

If I get rid of the third argument, the form displays as expected (unstyled). I can't see what I'm doing wrong here - can anyone help?

回答1:

{{ Form::text('text', $variable->name, array('class' => 'form-control')) }}

回答2:

I can see from the api that there is another argument expected:

http://laravel.com/api/source-class-Illuminate.Html.FormBuilder.html#235-246

('text', $name, $value, $options)

Your array needs to be the fourth argument to Form::input() - the third is the 'default' value. See Laravel's FormBuilder class:

public function input($type, $name, $value = null, $options = array())
