Validator Doc not working (FORMS API)

Resolved

(@tanckom)

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/).

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?

Hi, your field definition is incorrect you are using the “validator” key twice so the first validator (in_between) is cancelled with second one (is_required), to use both in_between and is_required your field definition should be
```
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" => 10, "max" => 100),
    	    ),
            array(
                "name" => "is_required"
            ),
        )
    );
    return $form;
}
```

Okay thanks, worked.

My final question about this one is, how can i use random number?

I found out if I give minimun a random number between 1-10 and max 11-20 it wont work always because for example:
Current randoms are: min:1 ; max 20 and you insert 4 and hit preview.
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
));

I am not sure, you would probably need to generate this numbers once and store them in user session or user cookie.

I tried with user session too, but somehow it didnt store them, is there something that disables it? ( I also used start_session() )

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.
