The HelperOptions class

This helper is used to generate a configuration form, the values of which are stored in the configuration table. Example: the “Preferences” page.

The HelperOptions helper is the recommended way for managing configurations for legacy part.

Options declaration

Fields inside [brackets] are optional. Values between {curly braces} list the possible values for this field.

$this->fields_options = [
  'general' => [
    'title' => $this->l('Carrier options'),                      // The title of the fieldset. If missing, default is 'Options'.
    'top' => $this->l('Text to display before the fieldset'),    // This text is display right above the first. Rarely used.
    'image' => 'url to icon',                                    // If missing, will use the default icon for the tab.
    'description' => $this->l('Display as description'),         // Displays an informational box above the fields.
    'info' => $this->l('Display as info'),                       // Displays an unstyled text above the fields.
    'fields' => [                                                // The various option fields.
      'PS_CARRIER_DEFAULT' => [                                  // The array is named after the option's ID. It must be the

        'title' => $this->l('Default carrier:'),                 // The name of the option.
        'desc' => $this->l('The default carrier used in shop'),  // The description of the option.
        'cast' => 'intval',                                      // Using this option, you can cast the variable's content
                                                                 // into a known value. You can use boolval, floatval, intval
                                                                 // or strval depending on value type you want to receive.
        'validation' => 'isInt',                                 // Validate the field with method of Validate class
        'type' => {'text', 'hidden', 'select', 'bool', 'radio',  // The kind of input field you want to use.
          'checkbox', 'password', 'textarea', 'file', 'textLang',
          'textareaLang', 'selectLang'},
        'autoload_rte' => 'true'                                 // Display a TinyMCE editor for textarea field only
        'suffix' => 'kg',                                        // Display after the field (ie. currency).

        'identifier' => 'id_carrier',                            // The unique ID for the form.
        'list' => [list do display as options],             // For select field only.
        'empty_message' => $this->module->l('Display if list is empty'), // For select field only

        'rows' => 5,                                             // For textarea fields only.
        'thumb' => 'url to thumb image',                         // For file fields only.
        'is_invisible' => {true, false}                          // Disable the field depending on shop context.
      'another_field' => [
    'submit' => [
      'title' => $this->module->l('Save'),
  'another fieldset' => ...

For multilang configuration fields you can use Lang version i.e. textLang is the multilang version of text field.

To save the HTML content of the TinyMCE editor, remember to use 'validation' => 'isCleanHtml'.

Basic declaration

Removing all the optional fields, this is how to build a basic HelperOptions element:

$this->fields_options = array(
    'general' => array(
        'title' => $this->l('Parameters'),
        'fields' => array(
            'PS_MYMODULE_OPTION1' => array(
                'title' => $this->l('Choose one'),
                'desc' => $this->l('Choose between Yes and No.'),
                'cast' => 'boolval',
                'type' => 'bool'
            'PS_MYMODULE_OPTION2' => array(
                'title' => $this->l('Add some text'),
                'desc' => $this->l('This is where you can add some text'),
                'cast' => 'strval',
                'type' => 'text',
                'size' => '10'

This specific code generates this HTML code (simplified here for readability reasons):

<form id="_form" name="_form">
      <labe>Choose one</label>
        <label><img alt="Yes" src="../img/admin/enabled.gif" title="Yes" /></label>
        <input type="radio" value="1" />
        <label><img alt="No" src="../img/admin/disabled.gif" title="No" /></label>
        <input type="radio" value="0" checked="checked" />
        <p>Choose between Yes and No.</p>
    <div class="clear"></div>
      <label>Add some text</label>
        <input type="text" value="" />
        <p>This is where you can add some text</p>

Radio button example

    'type' => 'radio',
    'title' => $this->module->l('My config title'),
    'validation' => 'isInt',
    'choices' => [
        'myconfigvalue1' => $this->module->l('My value 1'),
        'myconfigvalue2' => $this->module->l('My value 2'),

Checkbox example

    'type' => 'checkbox',
    'title' => $this->module->l('My config title'),
    'validation' => 'isInt',
    'choices' => [
        'myconfigvalue1' => $this->module->l('My value 1'),
        'myconfigvalue2' => $this->module->l('My value 2'),

Select example

    'type' => 'select',
    'title' => $this->module->l('My config title'),
    'validation' => 'isInt',
    'identifier' => 'id',
    'list' => [
        ['id' => 'myconfigvalue1', 'name' => $this->module->l('My value 1')],
        ['id' => 'myconfigvalue2', 'name' => $this->module->l('My value 2')],
