Price in add advert whitespace validation

At the moment in defaults.php i have:

array(
            "name" => "adverts_price",
            "type" => "adverts_field_text",
            "order" => 20,
            "label" => __("Pre?o (símbolo € é automático!)", "adverts"),
            "attr" => array(
               array( "key" => "value")
            ),
			"validator" => array(
                array( "name" => "is_required" )
            ),
			"filter" => array(
			array ("name" => "money" )
			)
        ),

Actually, all of the validators, except is_required are executed only if entered value is not empty.

The price field is technically never empty as WPAdverts on submit will use “money” filter and convert the submitted value (whatever it is to) “0.00”.

but coz price filter, money filter function isn’t working ..autonumeric bug my other plugin to price filter.. can you help me in is_required validation? to validate empty space and NULL ?
thanks

You can add following code to your theme functions.php it will trim whitespace characters from beginning and end of text in Title and Price fields, this will make required validation fail if entered string is just a ” “.

add_filter( "adverts_form_load", "trim_filter_test" );

function trim_filter_test( $form ) {
  if( $form['name'] != "advert" ) {
    return $form;
  }

  adverts_form_add_filter("trim", array(
      "callback" => "trim"
  ));

  foreach( $form["field"] as $key => $field ) {
    if( in_array( $field["name"], array( "post_title", "adverts_price" ) ) ) {

        if( ! isset( $field["filter"] ) ) {
            $field["filter"] = array();
        }

        $field["filter"][] = array( "name" => "trim" );
        $form["field"][$key] = $field;
    }
  }
  return $form;
}

It’s default 0 ? It’s possible to change value to 1? if it’s 0 , don’t show that value in adverts_list below title of ad..
And if people put ” ” or is NULL don’t give error just put 0 ..
If put value=1 default for me it’s ok, people will see that stupid value and change but if have 0 doesn’t show any value…

It’s not really possible to have a default = 1.

Ok thanks anyway Greg you’re really helpful ??
