Make each 'form-item' unique class

Alauddin commented 6 years ago

If you want unique class for each 'form-item'

1) copy the whole code above to template.php
2) replace 'theme' with your theme name

function yourthemename_form_element($element, $value) {

3) replace this line:

$output = '<div class="form-item"';

with this line

$output = '<div class="form-item-' . substr(strtolower(strtr($element['#title'], array(' ' => '-', '_' => '-', '[' => '-', ']' => '',  '(' => '', ')' => '', ':' => ''))) , 0, 15) . '"'; 

This will give you a class='form-item-title-goes-here'
A bit cumbersome with long classes (form-item+15 characters) but still a lot easier.

Not that this approach will

Xano commented 6 years ago

Not that this approach will break your class if the element's title changes, which happens if you have a multilingual site or you change the title string using the translation interface. It's best to use the element's name or ID attribute for this.

Common AND unique class

mariagwyn commented 6 years ago

If you would like to keep the common class as well as a unique class, modify the snippet in 3 above by adding "form-item form-item-". The first bit applies the common class, the second gives the unique class. The whole $output would be:
$output = '<div class="form-item form-item-' . substr(strtolower(strtr($element['#title'], array(' ' => '-', '_' => '-', '[' => '-', ']' => '', '(' => '', ')' => '', ':' => ''))) , 0, 15) . '"';
