How to add a custom field?

Hi @logaen,

Do you have some code that’s not working that I can have a look at and see if we can resolve?

Thanks
Phil

I can’t figure out where to put the code to have an additional field.
I would like to insert a custom field that may require an alphanumeric field of exact 16 digits.

Hi @logaen,

It would go in your functions.php in your theme or child theme, or a custom plugin file.

Here’s a fully example with what you’ve said above:

/* Add the field */
add_filter('post_age_gate_custom_fields', 'my_custom_fields', 10, 1);

function my_custom_fields($fields)
{
    $fields .= sprintf('<label>codice fiscale</label><br /> <input type="text" name="ag_field_codice_fiscale" value="%s" />', age_gate_set_value('ag_field_codice_fiscale'));
    $fields .= age_gate_error('ag_field_codice_fiscale');

    return $fields;
}

/* validate the field */
add_filter('age_gate_validation', 'my_validation_rules', 10, 1);

function my_validation_rules($rules)
{
    return array_merge($rules, [
    'ag_field_codice_fiscale' => 'required|min_len,16,max_len,16|alpha_numeric'
  ]);
}

/* Set the field display name */
add_filter('age_gate_field_names', 'my_field_names', 10, 1);

function my_field_names($names)
{
    return array_merge($names, [
    'ag_field_codice_fiscale' => "codice fiscale"
  ]);
}

/* We need to set a message for the alpha_numeric rule */
add_filter('age_gate_validation_messages', 'my_error_messages');
function my_error_messages($messages)
{
    return array_merge($messages, [
        'validate_alpha_numeric' => 'The {field} field can only contain alpha numeric characters',
    ]);
}

Thanks
Phil

Perfect. It works! Where does this data go?

Hi @logaen,

After the form is submitted, that data is gone. What do you want to do with it?

There are hooks to allow you to store it somewhere should you want to.

Thanks
Phil
