Hi,

I would like to have featured image as a required field, so I tried this code:

function my_validation($field_data, $form_data)
{
    list($fields,$errors)=$field_data;
  
    if ($form_data['id']==488)
    {
        if (empty($fields['_featured_image']['value']))
        {
            $errors['_featured_image'] = 'Missing featured image';
        }
    }
  
    return array($fields,$errors);
}
add_filter('cred_form_validate','my_validation',10,2);

But there must be something wrong, because the field is still not required.

Hi David,

Thank you for contacting Toolset support. I have checked the code you have provided, and it is working as expected.

- Please double check the form ID.
- Please try to check it by deactivating all third-party plugins (except Toolset) and switching back to the Default Theme (e.g. Twenty Sixteen theme) to see for any possible conflicts with any of the plugins or themes?

- If still issue arise, please provide temporary access (WP-Admin and FTP Login info) to your staging site.

Your next answer will be private which means only you and I have access to it.

=== Please backup your database and website ===

✙ I would additionally need your permission to de-activate and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important.

✙ Please add the Links to the [CRED Form] Edit Screen and [Page] Edit Screen where you have inserted this Form.

Thank you

Hello David,

There were some php errors and syntax mistakes in Child theme’s functions.php. I have fixed the below code and now featured image is made as required on both forms.

function sort_and_format_post_date_fields_func($atts)
{
  $atts = shortcode_atts( array(
    'postid' => '',
    'field' => '',
    'format' => 'j. F Y \o\d G:i'
	), $atts);
  $values = get_post_meta($atts['postid'], 'wpcf-datum-konani');
  usort($values, 'numbersort');
  $string = '';
  foreach($values as $value) {
    $date = date_i18n($atts['format'], $value);
    $prefix = $value < strtotime('0:00:00') ? '<span style="text-decoration:line-through;">' : '';
    $suffix = $value < strtotime('0:00:00') ? '</span>' : '';
    $string .= ($string == '' ? '' : '<br>') . $prefix . $date . $suffix;
  }
 
  return $string;
}

$form_ids[] = 292;

function validate_featured_image_size( $field_data, $form_data ){
 
    $form_id = array( 292,488 ); // add IDs of CRED forms
 
    $target_width = 300; // Edit
    $target_height = 200; // Edit
 
    if ( in_array( $form_data['id'], $form_id ) ) {
 
        // Split field data into field values and errors
        list( $fields,$errors ) = $field_data;
 
 		if (empty($fields['_featured_image']['value']))
        {
            $errors['_featured_image'] = 'Missing featured image';
        }
		else {
			$check = getimagesize( $fields['_featured_image']['value'] );
			if ( $check !== false ) {
 
				$width = $check[0];
				$height = $check[1];
 
				if ( $width !== $target_width || $height !== $target_height ) {
					$errors['_featured_image'] = "Obrázek nemá uvedené rozměry";
				}
        	}
		}
		
        $field_data = array($fields,$errors);
    }
 
    return $field_data;
}

Here is your older functions.php file (backup):
