[Resolved] Validate a repeatable audio field's size

I am using a form to upload audio files to a repeatable field created within toolset and I want to validate the size.

I am using the example found below, for the cred_form_ajax_upload_validate api, but I cannot manage to get it to validate on repeatable fields.
https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_ajax_upload_validate

I also tried to create a new custom repeatable file field (and not audio) so I could manually validate the type as well as the size but cannot manage to make it work.

Any thoughts? Can you point me in the right direction?
Thank you!

Hello,

The filter hook cred_form_ajax_upload_validate works only you upload files using WP media library, you can edit your post form, enable option " Use the WordPress Media Library manager for image, video, audio, or file fields", then follow the document you mentioned above to setup the custom codes, for example this thread:

Thank you for your answer.

Unfortunately, that code is not validating repeatable audio fields nor with repeating image fields nor single upload fields.

My two fields are wpcf-gallery and wpcf-_preview_filesvendors. I made sure I got my fields from the the Post Metadata.

Any thoughts?

Thanks for the feedback, the thread I mentioned above is just an example, you need to customize the codes according to your website settings, for example:
1) There is a custom repeating image field "gallery", which is created with Types plugin
2) You can setup your post form, enable option: Use the WordPress Media Library manager for image, video, audio, or file fields
3) Add below codes in your theme file "functions.php":

add_filter('cred_form_ajax_upload_validate','my_validation',10,2);
function my_validation($error_fields, $form_data)
{
    //field data are field values and errors
    list($fields,$errors)=$error_fields;
    //validate if specific form
    if ($form_data['id']==123)
    {
        //get the latest image size
		foreach($fields as $k => $v){
			if(strpos($k, 'wpcf-gallery') !== false){
				$size = $v['field_data']['size'];
				if ($size > 1000000) // no more than 1M 
				{
					$errors['wpcf-gallery'] = 'the image size should not be more than 1M bytes';
				}
			}
		};
    }
    return array($fields,$errors);
}

Please replace 123 with your form's ID

Thank you, Luo! That worked great for the both fields.
