如何在drupal 7中应用webform验证？

Question

我在drupal 7网站上有webforms.我想要的是验证我的webform字段.webform包含一个电话字段,该字段应接受数字字段,并且只能包含10个数字.是否有任何模块或我必须为此编码.

Answer 1

用于hook_form_alter()在drupal中应用自定义验证

创建模块,例如mymodule

文件mymodule.module

function mymodule_form_alter(&$form, &$form_state, $form_id)
{
    print $form_id;

    if($form_id=='webform_client_form_1') //Change webform id according to you webformid
    {
        $form['#validate'][]='mymodule_form_validate';
        return $form;
    }
}

function mymodule_form_validate($form,&$form_state)
{
    //where "phone" is field name of webform phone field
    $phoneval = $form_state['values']['submitted']['phone'];

    if($phoneval=='')
    {
        form_set_error('phone','Please fill the form field');
    }
    // Then use regular expression to validate it.
    // In above example i have check if phonefield is empty or not.
}
