Tonight, a big brother from the TP forum added me, saying that he also encountered this problem, haha! Come to think of it, I have encountered many things, should I share it? In fact, many of my things came from others, taken from the Internet and used on the Internet! Only by sharing more can we improve!

How to implement it

Upload pictures -- Save and display pictures -- JS gets thumbnail parameters -- Submit location parameters -- Image scaling and saving class processing pictures -- Save captured pictures -- Update database -- Jump

The last few screenshots

The following is an example screenshot

Main implementation code

Copy code The code is as follows:

public function cutimg()
{
$result = $this->upload('temp');
if (!is_array($result))
{
$this->redirect('index');
}
else
{
$this->assign('imgurl', '__ROOT__/' . C('ATTACHDIR') . '/temp/' . $result[0]['savename' ]);
$this->assign('imgname', $result[0]['savename']);
$this->display();
}
}

Copy code The code is as follows:

public function setavatar()
{
if (!empty($_REQUEST['cut_pos']))
{
// import('ORG.Util.ImageResize');
require('ImageResize.class.php');
$imgresize = new ImageResize();
// use the full path
$url = C('ATTACHDIR') . '/temp/' . trim($_POST['imgname']);
$imgresize->load($url);
dump($url);
$posary = explode(',', $_REQUEST['cut_pos']);
foreach($posary as $ k => $v)

$posary[$k] = intval($v);

if ($posary[2] > 0 && $posary[3] > 0) $imgresize->resize($posary[2], $posary[3]);

dump($posary);
// create filename rule
$uico = time( ) . '.jpg';
dump($uico);
$path = C('AVATAR');
// save 120*120 image
$imgresize->cut(120 , 120, intval($posary[0]), intval($posary[1]));
$large = 'l_' . $uico;
$imgresize->save($path . $large );

echo '';
// update database
}
else
{
// error reporting
}
}
