[Formsess-devel] drive the validation from Business layer (3): input tag

[Raoul P. <pie...@wa...>]

Hello,

The third request is about the Formsess Input tag. Now we really start =
with the subject.

At the moment, the type of an input tag must be coded in the template. =
And so you can't easily shift between radio and checkbox types for =
exemple.

To do it we need to delay the type controls in FormsessTagInput::getTag.

The changes would be:

- create the smarty_function_fs_input function:

    function smarty_function_fs_input($params, &$smarty) {
      $type =3D $params['type'];

      $fileName =3D 'fs_input_' .$type;
      $functionName =3D 'smarty_function_'.$fileName;
      unset($params['type']); =20

      require_once $smarty->_get_plugin_filepath('function',$fileName);
 =20
      return $functionName($params, $smarty);
    }=20

- remove the type controls from FormsessTagInput::getTag, that is the =
class becomes:

    class FormsessTagInput extends FormsessTag {
 =20
      function getTag() {
        $type  =3D 'input_' . $this->getAttributeValue('type');
        $this->setName($type);
=20
        // create the string with the smarty delimiters and all =
attributes
        $string =3D 'fs_input' .$this->glueAttributes(); // 'fs_input' =
here without tail underscore
        return $this->getCaptures() . $this->smartyEmbed($string);
      }
    }

- convert string to array in smarty_function_fs_input_checkbox:

    function smarty_function_fs_input_checkbox($params, &$smarty) {
    [...]                =20
      if (in_array($value, (array)$itemValues)) {
        $params['checked'] =3D 'checked';
      }
    [...]                =20

- put the radio control in smarty_function_fs_input_radio:
      =20
    function smarty_function_fs_input_radio($params, &$smarty) {
        $fs =3D& $GLOBALS['__fs_current'];
        $name  =3D $params['name'];

        // the "value" attribute is mandatory for a radio button
        if ( (! isSet($params['value']) || ($params['value'] =3D=3D '')) =
) {
          return '[fs:radio] the value is mandatory for a <fs:input =
type=3D"radio"> tag';
        }
    [...]            =20
