Question

我在使用Code Igniter时遇到了麻烦。我试图启用显示没有用的错误，据我所知，我正确地关注文档。我遇到的问题是模板中的validation_errors（）函数不会回应验证问题。验证过程正在运行（如果验证失败，则返回到表单），但不显示错误消息。然而，我已经从下面的控制器中包含了该方法并查看了表单。

$ this-＆gt; load-＆gt; model（＆＃39; admin_members＆＃39;，＆＃39; members＆＃39;，TRUE）; if（$ this-＆gt; input-＆gt; post（＆＃39; addmember＆＃39;））{

         $this->load->helper('form');
        $this->load->library('form_validation');
        // Displaying Errors In Div
        $this->form_validation->set_error_delimiters('<div class="error">', '</div>');

        // Validation For Name Field
        $this->form_validation->set_rules('mname', 'Member Name', 'required|min_length[15]|max_length[25]');
        $this->load->library('upload', $config);
        // Validation For Email Field
        $this->form_validation->set_rules('email', 'Email', 'required|valid_email');

        if($this->validation->run()== FALSE){
            $this->load->view('admin/member-management/add', $data);

        }

        else{
                $member_id = $this->members->add();

        if(!is_dir('images/members/' . $member_id )) mkdir('images/members/' . $member_id , 0777, TRUE);

        $config['upload_path'] = 'images/members/' . $member_id ."/";
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '22222';
        $config['max_width']  = '10242';
        $config['max_height']  = '10242';
        $config['file_name']  = "profile.jpg" ;
        $this->upload->initialize($config);
        $this->upload->do_upload('profile_image');

        $config = array();
        $config['upload_path'] = 'images/members/' . $member_id ."/";
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '22222';
        $config['max_width']  = '10242';
        $config['max_height']  = '10242';
        $config['file_name']  = "pan_card.jpg" ;    
        $this->upload->initialize($config);
        $this->upload->do_upload('pan_card');

        $config = array();
        $config['upload_path'] = 'images/members/' . $member_id ."/";
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '22222';
        $config['max_width']  = '10242';
        $config['max_height']  = '10242';
        $config['file_name']  = "id_proof.jpg" ;    
        $this->upload->initialize($config);
        $this->upload->do_upload('id_proof');

        $config = array();
        $config['upload_path'] = 'images/members/' . $member_id ."/";
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '22222';
        $config['max_width']  = '10242';
        $config['max_height']  = '10242';
        $config['file_name']  = "add_proof.jpg" ;   
        $this->upload->initialize($config);
        $this->upload->do_upload('add_proof');

        redirect('admin_member', 'refresh');

  }

}

Answer 1

替换

$this->validation->run() == FALSE

要

$this->form_validation->run() === FALSE

请更正您在控制器功能中检查表单验证规则的语法。

Answer 2

请务必在表单必须返回的视图中回显验证错误<?php echo validation_errors()?>。

在您的代码中，您还传递了我注意到的变量$data未在代码中的任何其他位置声明。我假设$data是一个数组，它将为视图保存一些变量，或者假设$data具有您传递给服务器的值。在这种情况下，您可以使用<?php echo set_values(//Value of the name parameter you give to the input)。如果您想要返回表单但又不想再次填写表格，这可能很有用。

作为额外奖励使用$this-form_validation->run() === FALSE代替$this->form_validation->run() == FALSE。这不会解决问题，但它确保如果攻击者将元素的返回类型更改为字符串，则字符串“TRUE”将不会计算为TRUE。

Lemme知道我是否回答了你的问题... :)
