Question

我正在尝试编写一个代码，我可以提交表单输入数据库中的内容，同时执行文件上传并将其存储在我的服务器内的文件夹中

文件夹位置称为上传，位于我网站的根目录

这是我的代码

controller（site.php）

 <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

 class Site extends CI_controller {

public function __construct()
{
    parent::__construct();
    // Your own constructor code
    $this->load->model("site_model");
    $this->load->helper(array('form', 'url'));
} 

public function cmain($type,$page)
{
    $data = $this->_initialize_data(); //this is just a bunch of variables that im calling in another function
    $data['type'] = $type;
    $data['page'] = $page;
    $this->load->vars($data);
    $this->load->view('site/cmain');
}


public function m1()
        {               

        $this->load->library('upload', $config);

            if(isset($_POST['m1']))
            {
                $suffix = $this->input->post("suffix");
                $fn = $this->input->post("fn");
                $mn = $this->input->post("mn");
                $ln = $this->input->post("ln");


                $newdata = array('suffix'=>$suffix,
                                'fn'=>$fn,
                                'mn'=>$mn,
                                'ln'=>$ln,

                                 );
                //this code is for the file upload
                           $config['upload_path'] = 'uploads';
                           $config['allowed_types'] = '*';

                           $this->load->library('upload', $config);

                           $data = array('upload_data' => $this->upload->data());
                 //end of file upload codes                 

                $this->db->insert('myself', $newdata); 

                redirect(base_url() . "site/complaint");    

            }

        }

查看（cmain.php）

<form action="<?php echo base_url();?>site/m1" name="details" id="details" method="post" enctype="multipart/form-data">
        <table class='table' width="100%">
            <tr>
            <td colspan='2'>
                <b><font color="#3B608C">Personal Information</font></b>
            </td>
        </tr>
        <tr>
            <td>
                Suffix  (e.g. Jr., III)
            </td>
            <td>
                <input type="text" name="suffix" id="suffix" value="">
            </td>
        </tr>
        <tr>
            <td>
                First Name*
            </td>
            <td>
                <input type="text" name="fn" id="fn" value="">
            </td>
        </tr>
        <tr>
            <td>
                Middle Name*
            </td>
            <td>
                <input type="text" name="mn" id="mn" value="">
            </td>
        </tr>
        <tr>
            <td>
                Last Name*
            </td>
            <td>
                <input type="text" name="ln" id="ln" value="">
            </td>
        </tr>
</table>

            <table>
        <tr>
        <td width="50%">
        Please attach documents pertinent to these complaints. <br>
        (Attach a zip file if more than one document)<br>
        </td>
        <td align="center">
        <input name = "userfile" type="file" class="input-xlarge" id = "userfile" />
        </td></tr>
        </table>
        <input type="submit" value="Submit Form" class="pull-right" id="submit" name="m1"/>
</form>

表单在数据库中正确发布，如后缀fn，ln和mn 但是文件上传不起作用

我尽力遵循codeigniter docs样本，只得到了我认为我需要的行

我做错了什么？

感谢

Answer 1

终于搞定了

我将它用于文件上传部分

                //start of file upload code
                $config['upload_path'] = './uploads/';
                $config['allowed_types'] = '*';
                $this->load->library('upload', $config);
                $this->upload->do_upload();
                $data = $this->upload->data();
                //end of file upload code

并更改了

<form action="<?php echo base_url();?>site/m1" name="details" id="details" method="post" enctype="multipart/form-data">

进入

<?php echo form_open_multipart('site/c_upload');?>

我认为您必须设置文件上传首选项

$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';

表格助手

$this->load->helper(array('form', 'url'));

For further detail have a look

Answer 3

您是否为“uploads”文件夹设置了写入权限？（例如：php.net/manual/en/function.chmod.php）

始终进行测试驱动开发。我从this url

获得了以下代码块

if ( ! $this->upload->do_upload())
{
    $error = array('error' => $this->upload->display_errors());

    $this->load->view('upload_form', $error);
}
