提问by itsover9000
im trying to write a code where i can submit a form enter the contents in a database, at the same time perform a file upload and have it stored in a folder inside my server
我正在尝试编写一个代码，我可以在其中提交表单 在数据库中输入内容，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
the folder location is called uploads which is located at the root of my site
文件夹位置称为uploads，位于我网站的根目录
here is my code
这是我的代码
controller (site.php)
控制器（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");
}
}
view (cmain.php)
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>
the form posts properly in the database like the suffix,fn,ln and mn however the file upload isnt working
表单在数据库中正确发布，如后缀、fn、ln 和 mn，但文件上传不起作用

I think you must have to set file upload preference
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';
Form Helper
表单助手
$this->load->helper(array('form', 'url'));

Did you set writing permissions for 'uploads' folder? (example: php.net/manual/en/function.chmod.php)
Always do test driven development. I got below code block from this url
if ( ! $this->upload->do_upload()) { $error = array('error' => $this->upload->display_errors()); $this->load->view('upload_form', $error); }
您是否为“上传”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。我从这个网址得到以下代码块
if ( ! $this->upload->do_upload()) { $error = array('error' => $this->upload->display_errors()); $this->load->view('upload_form', $error); }
