我已经为多张图片上传创建了表单。但无法使用该表单。只有一张图片上传..我希望将多张图片上传到文件夹并将图片名称保存在数据库中..

我的查看文件

<html>

    width:750px;
    margin:0 auto;
    //border:5px solid #000000;

a）而不是写这个<input type="file" multiple="true" name="userfile" size="20" />写<input type="file" name="userfile[]" size="20" />

b）在您的控制器内部，您可以执行以下操作：

$files = $_FILES;
$count = count($_FILES['userfile']['name']);
for($i=0; $i<$count; $i++)
{

    $_FILES['userfile']['name']= $files['userfile']['name'][$i];
    $_FILES['userfile']['type']= $files['userfile']['type'][$i];
    $_FILES['userfile']['tmp_name']= $files['userfile']['tmp_name'][$i];
    $_FILES['userfile']['error']= $files['userfile']['error'][$i];
    $_FILES['userfile']['size']= $files['userfile']['size'][$i];    

    $this->upload->initialize($config);
    $this->upload->do_upload();
    $image_data = $this->upload->data();
}

你不能只添加一个multiple属性到<input type="file" />，那是行不通的。

您必须使用第三方模块/插件，例如Uploadify，才能运行此功能。

您还可以查看本教程，了解如何在 CodeIgniter 中集成 Uploadify（尽管我在您的代码中看不到任何 CodeIgniterish，但您仍然将问题标记为 CI 相关）

使用它打开您的上传表单：

echo form_open_multipart('admin/do_upload');

放一个或多个后：

<input type="file" name="name" size="20" />

并使用这样的功能：

public function do_upload() {
        $config['upload_path'] = './assets/images/upload/';
        $config['allowed_types'] = 'gif|jpg|png';

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

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

            $this->load->view('admin/images', $error);
        } else {
            $data = array('upload_data' => $this->upload->data());
        }
    }
