嗨，每一个人，
我正在尝试上传数据库中的文件路径，但它重定向相同，文件不上传可以任何人帮助我..
这是我的控制器。
<?php
if (!defined ('BASEPATH'))exit('no direct scripts allowed ');
class Main extends CI_Controller
{
function __construct ()
{
parent::__construct();
$this->load->library('session');
}
function insert_quiz_data()
{
$this->load->library('form_validation'); //loading validation library
$this->form_validation->set_rules('qtitle','quiz_title'); //setting rules for validation
$this->form_validation->set_rules('qcategory1','quiz_category1');
$this->form_validation->set_rules('qcategory2','quiz_category2');
$this->form_validation->set_rules('qcategory3','quiz_category3');
$this->form_validation->set_rules('astatus','email');
$this->form_validation->set_rules('userfile', 'quiz_image_path', 'callback__do_upload'); //userfile is the upload file field name in form ,
echo 'testing';
if($this->form_validation->run()!=false)
{
//Get the info from the form
$username = $this->input->post('qtitle');
$password = $this->input->post('qcategory1');
$passconf = $this->input->post('qcategory2');
$date = $this->input->post('qcategory3');
$email = $this->input->post('astatus');
$temp=$this->upload->data();
$image=$temp['file_name'];// to get image file name rom upload script , as it could be stored in the databae
//load the model
$this->load->model('quiz_mode');
//execute the registration query
$data = $this->quiz_mode->register_user($username,$password,$passconf,$date,$image,$email);
//if $data == TRUE
if($data)
{
echo "you have successfully made your registration";
$this->load->view('logged_in_area');
}
else
{
echo "faillled";
}
}
else{
//You arrived here just in case the form fields are not correct
$this->load->view('logged_in_area'); //loading reg form here
}
}
public function _do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$field_name = 'userfile';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload($field_name))
{
$this->form_validation->set_message('_do_upload', $this->upload->display_errors());
return FALSE;
}
else
{
$image_data = $this->upload->data();
$filename = $image_data['file_name'];
$config = array
(
'source_image' => $image_data['full_path'],
'new_image' => './uploads/thumbs/',
'maintain_ratio' => false,
'width' => 300,
'height' => 200
);
$this->load->library('image_lib', $config);
$this->image_lib->resize();
return TRUE;
}
}
}
我的模特课程：
<?php
class File_model extends CI_Model
{
function File_model()
{
parent::__construct();
}
function register_user($username,$password,$passconf,$date,$image,$email)
{
$data= array('username'=>$username,
'password'=>$password,
'passconf'=>$passconf,
'date'=>$date,
'image'=>$image,
'email'=>$email
);
$res= $this->db->insert('register', $data); //register is my table name
return $res;
var_dump($res);
}
}
?>
我的观点
<html>
<body>
<?php $this->load->helper('form'); ?>
<?php echo form_open_multipart('index.php/main'); ?>
<?php echo validation_errors(); ?>
<table width="348" align="center" cellpadding="0" cellspacing="0">
<tr>
<td colspan="2" align="center"><h2><strong>REGISTERATION AREA</strong></h2></td>
</tr>
<tr><?php //echo validation_errors(); ?>
<td width="97" height="40"><label for"username"> <strong>Username </strong></label></td>
<td width="249"><input type="text" id="username" name="username" value="<?php echo set_value('username'); ?>"/></td>
</tr>
<tr>
<td><label for"password"> <strong>Password </strong></label></td>
<td><input type="password" name="password" id="password" value="<?php echo set_value('password'); ?>"/></td>
</tr>
<tr>

任何人都可以帮助我。 感谢。

在你的_do_upload函数中，你没有在函数中传递参数，它不能使用$field_name
尝试改变它：
public function _do_upload($field_name)
您的代码中存在不同的问题。 首先，在验证之前加载视图，这样视图始终是diplaied。 尝试我的以下代码（只是索引函数）：
function index()
{
$this->load->library('form_validation'); //loading validation library
$this->form_validation->set_rules('username','username','Rquired'); //setting rules for validation
$this->form_validation->set_rules('password','password','required|md5|trim');
$this->form_validation->set_rules('passconf','password confirmation','required|md5|trim');
$this->form_validation->set_rules('datepicker','date','required');
$this->form_validation->set_rules('email','email','required');
$this->form_validation->set_rules('userfile', 'Image', 'callback__do_upload'); //userfile is the upload file field name in form ,
if($this->form_validation->run()!=false)
{
//Get the info from the form
$username = $this->input->post('username');
$password = $this->input->post('password');
$passconf = $this->input->post('passconf');
$date = $this->input->post('datepicker');
$email = $this->input->post('email');
$temp=$this->upload->data();
$image=$temp['file_name'];// to get image file name rom upload script , as it could be stored in the databae
//load the model
$this->load->model('file_model');
//execute the registration query
$data = $this->file_model->register_user($username,$password,$passconf,$date,$image,$email);
//if $data == TRUE
if($data)
{
echo "you have successfully made your registration";
}
else
{
echo "faillled";
}
}
else{
//You arrived here just in case the form fields are not correct
$this->load->view('register_form'); //loading reg form here
}
}
