CRED plugin allows you to build forms for front-end user registration and editing. These forms can include user fields and display them with your HTML styling. They also support input validation and automatic email notifications.
When you ask for help or report issues, make sure to tell us the structure and the settings of your form.

Problem: I would like to use the Forms API to validate each image that is uploaded in a single or repeating custom field. It doesn't seem to be working, in the logs I see a PHP notice about trying to get property of a non-object.
Solution: Make sure the User has permission to publish Media if you are using Toolset Access Control. Make sure the Form's markup structure doesn't include any extra closing div tags. Use the following custom code to validate a repeating image field:
add_filter('cred_form_ajax_upload_validate','rep_img_size_validation',10,2);
function rep_img_size_validation($error_fields, $form_data)
{
error_log(' validation script is invoked ');
$forms = array( 29, 49 );
$size = 1024000;
$field_slug = 'your-repeating-image-slug';
$error_msg = 'Maximum size is 1MB, please try again.';
//field data are field values and errors
list($fields,$errors)=$error_fields;
//validate if specific form
if (in_array( $form_data['id'], $forms ) && isset($fields['wpcf-' . $field_slug]['field_data']['size']))
{
//check if this field instance img is bigger than $size (bytes)
$instance_size = array_pop($fields['wpcf-' . $field_slug]['field_data']['size']);
if ( $instance_size > $size )
{
//display error message for this field instance
$errors['wpcf-' . $field_slug] = $error_msg;
}
}
//return result
return array($fields,$errors);
}
To validate a single field, copy the code above and make the following adjustments:
- Change the function names to prevent a PHP error
- Change the field slug
- Remove array_pop from the instance_size definition like this:
// for repeating images
// $instance_size = array_pop($fields['wpcf-' . $field_slug]['field_data']['size']);
// for single images
$instance_size = $fields['wpcf-' . $field_slug]['field_data']['size'];
Problem:
If you export a Toolset Form from one site and import it to another any custom markup etc. is lost, the form reverts to the default state as if it had just been newly created.
Solution:
This is a confirmed bug that is fixed in Forms 2.3.4
