I’m doing this one instead. I added
function my_acf_validate_value( $valid, $value, $field, $input ) {
$current_id = get_current_user_id();
$wp_user_id = 'user_' . $current_id;
$current_email = get_the_author_meta('user_email', $current_id);
if( $_POST['acf']['register'] == 'true' ) {
if($value == "" || $value == " ") {
$valid = "Email field cannot be empty";
} elseif( email_exists($value) && $value != $current_email ) {
$valid = "This email already exists. Use a unique email";
}
}
return $valid;
}
in the form that was generated I added a hidden field for register
$options = array(
'post_id' => $user_id,
/* my field group grabs unit, home phone, and cell phone acf */
'field_groups' => array('3307', ),
'submit_value' => 'Update',
'html_after_fields' => '<input type="hidden" name="acf[register]" value="true"/>',
);
acf_form( $options );
