Add checkbox to “Agree to T&C” on add ads page

Hi, with some custom programming this is possible, here https://wpadverts.com/documentation/custom-fields/ you can find a code snippet explaining how to add a new Checkbox field to the Adverts Add form, you will need to customize it a bit to remove the text field and make the checkbox required, so your function will look somewhat like this

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

    $form["field"][] = array(            
        "name" => "my_custom_checkbox",
        "type" => "adverts_field_checkbox",
        "order" => 25,
        "label" => "Custom Checkbox",
        "is_required" => false,
        "validator" => array( array( "name" => "is_required" ) ),
        "max_choices" => 2,
        "options" => array(
            array("value"=>"1", "text"=>"One"),
            array("value"=>"2", "text"=>"Two"),
        )
    );
    
    return $form;
}

Hi Greg,

I′ve tried the following but is not working at all, what am I missing?

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" => "my_custom_checkbox",
        "type" => "adverts_field_checkbox",
        "order" => 25,
        "label" => "Termos e Condi??es",
        "is_required" => true,
        "validator" => array( 
            array("name"=>"is_required", "text"=>"Declaro que li e aceito os Termos e Condi??es do Trabalhitos"),
        )
    ); 
    return $form;
}

What do you mean by “not working at all”? The field does not show in the form or it shows but is not required?

Additionally, your code is incorrect in the “validator” option and it is missing the “options” it should be

add_filter( "adverts_form_load", "adverts_add_tos" );
function adverts_add_tos( $form ) {
    if( $form["name"] != "advert" ) {
        return $form;
    }

    $form["field"][] = array(            
        "name" => "my_custom_checkbox",
        "type" => "adverts_field_checkbox",
        "order" => 25000,
        "label" => "Terms and Conditions",
        "is_required" => true,
        "validator" => array( 
            array( 
                "name"=>"is_required", 
                "default_error" => "You have to agree to terms and conditions" 
            ),
        ),
        "options" => array(
            array( 
                "value" => 1, 
                "text" => "I agree to terms and conditions" 
            )
        )
    ); 

    return $form;
}

Amazing Greg, now it works great.
Many thanks
