Hi @sami616
Could you please tell me if this “registration template” is on front end or back end?
If it is on the front end, I think you can add a hidden input on your form to mark it as a registration page. Maybe something like this:
acf_form(array(
'html_after_fields' => '<input type="hidden" name="acf[register]" value="true"/>',
));
After that, you can check this hidden input using the $_POST variable. It should be something like this:
add_filter('acf/validate_value/name=sr_email', 'my_acf_validate_email', 10, 4);
function my_acf_validate_email( $valid, $value, $field, $input ){
if( !$valid ) {
return $valid;
}
if(($_POST['acf']['register'] == 'true') && email_exists($value)){
$valid = 'Email already in use';
}
return $valid;
}
I hope this helps.
