Title: Validator Doc not working (FORMS API) Last modified: September 19, 2016 --- # Validator Doc not working (FORMS API) * Resolved [tanckom](https://wordpress.org/support/users/tanckom/) * (@tanckom) * [9 years, 7 months ago](https://wordpress.org/support/topic/validator-doc-not-working-forms-api/) * Hello, So i tried to implement a min and max number into a text field (info take from here: [https://wpadverts.com/documentation/forms-api/](https://wpadverts.com/documentation/forms-api/)). * I included in my wpadverts/includes/functions.php this codes: * ``` add_filter( "adverts_form_load", "my_adverts_form_load" ); function my_adverts_form_load( $form ) { if( $form["name"] != "advert" ) { return $form; } $form["field"][] = array( "name" => "check", "type" => "adverts_field_text", "order" => 25, "label" => "Input a number between 10 and 100", "is_required" => true, "validator" => array( array( "name" => "in_between", "min" => 10, "max" => 100, )), "validator" => array( array( "name" => "is_required" ), ) ); return $form; } function in_between( $data, $params = null ) { if( isset( $params["min"] ) && $data < $params["min"] ) { return "to_small"; } if( isset( $params["max"] ) && $data > $params["max"] ) { return "to_big"; } return true; } adverts_form_add_validator("in_between", array( "callback" => "in_between", "label" => "In Between", "default_error" => __( "Incorrect value.", "adverts" ), "message" => array( "to_small" => "Value has to be greater than %min%.", "to_big" => "Value has to be smaller than %max%." ), "validate_empty" => false )); ``` * However it’s not working. Whenever I insert a number outside of min-max, it continues like the limits do not exists. How can I change this?

Page is going to reload randoms and the new randoms are: min: 9 ; max:13 The input from before didnt work because it was compared to the new randoms. How can i check the input with current randoms instead with the next (because they are not always true). Example: * add_filter( “adverts_form_load”, “my_adverts_form_load” ); function my_adverts_form_load( $form ) { if( $form[“name”] != “advert” ) { return $form; } $form[“field”][] = array( “name” => “check”, “type” => “adverts_field_text”, “order” => 25, “label” => “Input a number between 10 and 100”, “is_required” => true, “validator” => array( array( “name” => “in_between”, “params” => array(“min” => rand ( 1 , 10),“ max” => rand ( 11 , 20 )), ), array( “name” => “is_required” ), ) * ); return $form; } * function in_between( $data, $params = null ) { if( isset( $params[“min”] ) && $data < $params[“min”] ) { return “to_small”; } * if( isset( $params[“max”] ) && $data > $params[“max”] ) { return “to_big”; } * return true; } adverts_form_add_validator(“in_between”, array( “callback” = > “in_between”, “label” => “In Between”, “default_error” => __( “Incorrect value.”,“ adverts” ), “message” => array( “to_small” => “Value has to be greater than % min%.”, “to_big” => “Value has to be smaller than %max%.” ), “validate_empty” => false )); * Plugin Author [Greg Winiarski](https://wordpress.org/support/users/gwin/) * (@gwin) * [9 years, 7 months ago](https://wordpress.org/support/topic/validator-doc-not-working-forms-api/#post-8205319) * I am not sure, you would probably need to generate this numbers once and store them in user session or user cookie. * Thread Starter [tanckom](https://wordpress.org/support/users/tanckom/) * (@tanckom) * [9 years, 7 months ago](https://wordpress.org/support/topic/validator-doc-not-working-forms-api/#post-8205643) * I tried with user session too, but somehow it didnt store them, is there something that disables it? ( I also used start_session() ) * Plugin Author [Greg Winiarski](https://wordpress.org/support/users/gwin/) * (@gwin) * [9 years, 7 months ago](https://wordpress.org/support/topic/validator-doc-not-working-forms-api/#post-8209090) * I don’t know, this is more of a general PHP programming question, maybe sessions on your server do not work or you are starting the session after some content has been sent to browser n which case the session won’t start.
