Question

我正在使用http://foliotek.github.io/Croppie插件来裁剪图片。上传图片后，我必须在弹出窗口中显示裁剪部分。从弹出窗口，我必须裁剪图像。下面的代码是在同一页面上显示图像。我想上传一张图片，该图片应该显示在弹出窗口中，用户可以从中裁剪图片。我不知道该怎么做。你能帮帮我吗？

<?php
    if(isset($_POST['imagebase64'])){
        $data = $_POST['imagebase64'];
        list($type, $data) = explode(';', $data);
        list(, $data)      = explode(',', $data);
        $data = base64_decode($data);
      file_put_contents('image64.png', $data);
    }
?>
