1. We first need to create a table

Copy code The code is as follows:

CREATE TABLE IF NOT EXISTS `tp_image` (
`id` int(11 ) NOT NULL AUTO_INCREMENT,
`image` varchar(200) NOT NULL,
`create_time` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET =utf8;

2. Then add the configuration in the conf file (the last configuration is optional, just for the convenience of unified management of URL paths)

Copy code The code is as follows:

return array(
'URL_MODEL' => ; 2, // If your environment does not support PATHINFO, please set it to 3
'DB_TYPE' => 'mysql',
'DB_HOST' => ; 'thinkphp',
'DB_USER' => 'root',
'DB_PWD' => ',
'DB_PORT' => '3306',
'DB_PREFIX' = > Replace the Upload directory
in the root directory '__UPLOAD__' =>
3. Add an Image module (you can choose any name)

Copy code

The code is as follows:

class ImageAction extends Action{

/**

* Create index entry method */ public function index(){ $image=M('Image'); ;find(); //Get the last uploaded image $this->assign('data',$data); ;

4. Create the corresponding index view file (index.html)

Copy code

The code is as follows:

Insert title here

Upload allowed file types: gif png jpg image files, And generate 2 thumbnails, the large image is watermarked, and the original image will be deleted after generation.

5. Select the image and click the upload button, it will jump to the upload method of the Image module. There is no such method on the Image module yet, so we create it

Copy code The code is as follows:

class ImageAction extends Action{

/** <*>*/
Public function index () {
$ Image = m ('Image');
$ data = $ image- & gt; order ('create_time desc') ;find(); //Get the last uploaded image

var_dump($data);
$this->assign('data',$data);
$this->display ();
if(!empty($_FILES))

6. If the submission is not NULL, jump to the _upload method. This method implements the image upload function

Copy code

The code is as follows:

class ImageAction extends Action{

/**
      * Create index entry method
       */
public function index(){
$image=M(' Image'); ; $ this->assign('data',$data); Jump to _upload method
public function upload(){ $this->_upload( );
}

}

                                                        >                   $upload = new UploadFile(); $upload->allowExts = explode (',', 'jpg,gif,png,jpeg');
//Set the attachment upload directory
The thumbnail diagram is effective for image files
$ upload-& gt; thumb = true;
// Set the reference image library package path
$ upload- & gt; imageClasspath = '@.org.image'
                                                                                                                                                                                        $ upload->thumbMaxWidth = '400,100';
🎜> $upload-> ;saveRule = 'uniqid';
Upload failed
if (!$upload ->upload())

else
{
                                                                                                                     >                  import('@.ORG.Image');                                                                                                                                                                                         : :water($uploadList[0]['savepath'] . 'm_' . $uploadList[0]['savename'], APP_PATH.'Tpl/Public/Images/logo.png');

// The picture name is assigned to the field image
$ _post ['Image'] = $ uploadlist [0] ['savename'];
}
$ model = m ('image');
//Save the current data object
$data['image'] = $_POST['image'];
$data['create_time'] = NOW_TIME;
$list = $model->add ($data);
if ($list !== false)
{
$this->success('Uploaded image successfully!');
}
else
{
                                                                                                                                                                                                             ‐
The upload was successful and two thumbnails were generated

What needs to be explained is:

The image upload class (UploadFile.class.php) and image model class (Image.class.php) that come with ThinkPHP require the full version of the ThinkPHP package.

If not, you need to create a folder (ORG) in Lib, then go to the official website to download the expansion package and put these two files into the ORG folder.
