* [6 years, 11 months ago](https://wordpress.org/support/topic/validation-return-value-problem/)
* I use validation code `function wpuf_unique_kimlik_no_uyari( $error ) {
if (
isset( $_POST[‘musteri_kimlik_numarasi’] ) ) { global $wpdb; $kimlikno = $_POST[‘
musteri_kimlik_numarasi’]; $product_id = $wpdb->get_var( $wpdb->prepare( “SELECT
post_id FROM $wpdb->postmeta WHERE meta_key=’musteri_kimlik_numarasi’ AND meta_value
=’%s’ LIMIT 1″, $kimlikno ) ); if ( $product_id ) { return __( ‘This is an ERROR!’);}}
return ”; } add_filter( ‘wpuf_add_post_validate’, ‘wpuf_unique_kimlik_no_uyari’);`
* [user document page](https://wedevs.com/docs/wp-user-frontend-pro/developer-docs/filters/wpuf_add_post_validate/)
* I want to add a value to return message like as:
* ```
function wpuf_unique_kimlik_no_uyari( $error ) {
if ( isset( $_POST['musteri_kimlik_numarasi'] ) ) {
global $wpdb;
$kimlikno = $_POST['musteri_kimlik_numarasi'];
$product_id = $wpdb->get_var( $wpdb->prepare( "SELECT post_id FROM $wpdb->postmeta WHERE meta_key='musteri_kimlik_numarasi' AND meta_value='%s' LIMIT 1",
$kimlikno ) );
$sonucc = get_field('musteri_danismani', $product_id);
$tpt = the_field('calisan_adi_soyadi', $sonucc);
$tpt2 = the_field('calisan_sirket_numarasi', $sonucc);
if ( $product_id ) {
return __( $tpt ."". $tpt2 );
}
}
return '';
}
add_filter( 'wpuf_add_post_validate', 'wpuf_unique_kimlik_no_uyari' );

* Hello [@uniak](https://wordpress.org/support/users/uniak/)
* I’m really sorry for being late. My apologies.
* However, where did you get the `the_field` function? I mean, how did you manage
it?
* We are not understanding the code you wrote. A few descriptions would be appreciable.

* [@thebengalboy](https://wordpress.org/support/users/thebengalboy/) Thanks for
your reply 🙂
* I solved my problem.
* the_field is a advanced custom field code. You can look at: [https://www.advancedcustomfields.com/resources/the_field/](https://www.advancedcustomfields.com/resources/the_field/)
* I solved my problem with this code type:
* ```
function wpuf_unique_identity_no_error( $error ) {
if ( isset( $_POST['customer_identity_no'] ) ) {
global $wpdb;
$identityno = $_POST['customer_identity_no'];
$product_id = $wpdb->get_var( $wpdb->prepare( "SELECT post_id FROM $wpdb->postmeta WHERE meta_key='customer_identity_no' AND meta_value='%s' LIMIT 1", $identityno ) );
$resultt = get_field('customer_advisor', $product_id);
$tpt = get_field('customer_name_surname', 'user_'.$resultt);
$tpt2 = get_field('advisor_company_phone', 'user_'.$resultt);
$text1 = 'According to the information you have given your registration is in our system.
Your advisor is: "';
$text2 = '" . You can contact him/her with ';
$text3 = ' phone number.';
$emp = 'According to the information you have given your registration is in our system.
Your advisor has not yet been assigned. You can get information by calling +0 000 000 000 phone number.';
if (( $product_id ) and (is_null($resultt))) {
return $emp;
}
elseif(( $product_id ) and ($resultt)) {
return $text1 . "" . $tpt . "" . $text2 . "" . $tpt2 . "" . $text3;
}
}
return '';
}
add_filter( 'wpuf_add_post_validate', 'wpuf_unique_identity_no_error' );
```
