Problem: I am trying to validate a custom field with cred_form_validate, but I cannot validate a specific field. Errors never appear in the form.
Solution: Be sure to include the form_messages field in the Form builder so errors can be displayed. Then use the following syntax to validate a custom field:
function fn_cred_form_validate($error_fields, $form_data)
{
list($fields,$errors)=$error_fields;
if ($form_data['id']==221) {
if (empty($fields['wpcf-application-tour-number']['value'])) {
//set error message for my_field
$errors['application-tour-number']='Please select tour first';
}
}
return array($fields,$errors);
}
add_filter('cred_form_validate','fn_cred_form_validate',10,2);
Notice that the wpcf- prefix is required in the $fields array, but should not be included in the $errors array.
Problem: I have defined a custom field in my Form and set its value using a URL parameter. I would like to hide that field on the front-end, but if I use HTML comments the field value is not saved. How can I hide the field but save the value from a URL parameter?
Solution: Use CSS to hide the field itself or a container element:
Problem: I am using a Fields and Text block to display some text, including the post slug. I have set the text-transform property for this block to be "uppercase" but the slug always displays in lowercase.
Solution: It seems that GeneratePress includes some styles for H1 elements that includes the property text-transform: none;, and you would have to override that using custom CSS. Add the CSS class tb-uppercase-override to the Fields and Text block, then add this CSS in the template, an enqueued CSS file, or in Appearance > Customize > Additional CSS:
