This thread is resolved. Here is a description of the problem and solution.
Problem: I would like to require Users to upload an image and select at least one taxonomy term in my Form.
Solution: You can make a custom field image required by editing the custom field in Toolset > Custom fields > Post fields. You can use a custom code snippet with the Forms API to validate at least one term checkbox is checked:
<?php
/**
* New custom code snippet.
*/
toolset_snippet_security_check() or die( 'Direct access is not allowed' );
add_filter('cred_form_validate','term_checkboxes_form_validation', 10, 2);
function term_checkboxes_form_validation( $field_data, $form_data ) {
$tax = 'app-name';
$forms = array( 15 );
$msg = 'At least one checkbox is required.';
// you should not edit below this line
// field data are field values and errors
list($fields,$errors)=$field_data;
// validate if correct CRED form ID
if ( in_array( $form_data['id'], $forms ) ) {
if ( !isset($fields[$tax]['value'][0]))
$errors[$tax] = $msg;
}
return array( $fields, $errors );
}
