I have an array like this:

Array

(

    [enabled] => Array

        (

            [:input[name="email"]] => Array

                (

                    [checked] => 1

                )



        )



)

what would be the best way to extract the name attribute using php?
I need to check the value of email like this:

if(!empty($array['enabled']['email'])){

// do some stuff.

}

The name value is set by some external component and that can be anything and what i need to to is, always check on my implementation that this dynamic attribute is set and not empty. This form field is added by other module and i am trying to check this on hook_form_alter and add validation handler based on the value submitted.

Thanks in advance.

To extract the `name` attribute from each form field in the array, you can loop through the array and access the `name` key of each sub-array. Here's an example code snippet in PHP:

php
foreach ($array as $field) {
echo $field['name'] . "
";
}


This code will output the `name` attribute of each form field in the array:


field1
field2
field3
