Question

我目前正在开发一个codeigniter项目，我正在尝试使用form_validation库并且我遇到了一个小问题..

我创建了一个验证某些字段的函数。离。

public function validate_employee_data($data) {
    var_dump("EMPLOYEE");
    $this->form_validation->set_rules($data['firstname'], 'First Name', 'required');
    $this->form_validation->set_rules($data['lastname'], 'Last Name', 'required');
    $this->form_validation->set_rules($data['nickname'], 'Nick Name', 'trequired');
    $this->form_validation->set_rules($data['email'], 'Email Address', 'required|valid_email');
    $this->form_validation->set_rules($data['contact_no'], 'Contact Number', 'required|min_length[11]|max_length[12]');
    $this->form_validation->set_rules($data['group_tags'], 'Group Tags', 'required');

    if($this->form_validation->run() == FALSE) {
        echo validation_errors();
    }
    else {
        // Do something
    }
}

我试过var_dump $ data并且它不是空的但是验证仍然会抛出＆＃34;（这）字段是必需的＆＃34;，我有点困惑的是这个错误保持的原因是什么出现。

先谢谢你们..

Answer 1

答案：表单验证只能与表单字段名称一起使用，而不能与变量本身一起使用。

Answer 2

昵称字段，trequired？这不是必需的吗？

$this->form_validation->set_rules($data['nickname'], 'Nick Name', 'trequired');

到

$this->form_validation->set_rules($data['nickname'], 'Nick Name', 'required');

或者您的表单字段可以与验证相匹配，也可以验证

Answer 3

first of all , please check form validation libraries to load in autoload or your function uppar side, if yes so please ignore it.

Please Use this code

public function validate_employee_data($data) {
    var_dump("EMPLOYEE");
    $this->form_validation->set_rules('firstname', 'First Name', 'required');
    $this->form_validation->set_rules('lastname', 'Last Name', 'required');
    $this->form_validation->set_rules('nickname', 'Nick Name', 'required');
    $this->form_validation->set_rules('email', 'Email Address', 'required|valid_email');
    $this->form_validation->set_rules('contact_no', 'Contact Number', 'required|min_length[11]|max_length[12]');
    $this->form_validation->set_rules('group_tags', 'Group Tags', 'required');

    if($this->form_validation->run() == FALSE) {
        echo validation_errors();
    }
    else {
        // Do something
    }
}
