  • PHP+jQuery.photoClip.js支持手势的图片裁剪上传实例

    PHP+jQuery.photoClip.js支持手势的图片裁剪上传实例,在手机上双指捏合为缩放,双指旋转可根据旋转方向每次旋转90度,在电脑上鼠标滚轮为缩放,双击则顺时针旋转90度。

    下面让我们来看看核心代码:

    post的是base64,后端处理base64转存图片。

     1 $("#clipArea").photoClip({ 
     2      200, 
     3     height: 200, 
     4     file: "#file", 
     5     view: "#view", 
     6     ok: "#clipBtn", 
     7     loadStart: function() { 
     8         $(".photo-clip-rotateLayer").html("<img src='images/loading.gif'/>"); 
     9         console.log("照片读取中"); 
    10     }, 
    11     loadComplete: function() { 
    12         console.log("照片读取完成"); 
    13     }, 
    14     clipFinish: function(dataURL) { 
    15         $.ajax({ 
    16             url: "upload.php", 
    17             data: {str: dataURL}, 
    18             type: 'post', 
    19             dataType: 'html', 
    20         }) 
    21     } 
    22 });


    upload.php图片上传

    1 $base64 = htmlspecialchars($_POST['str']); 
    2 if (preg_match('/^(data:s*image/(w+);base64,)/', $base64, $result)) { 
    3     $type = $result[2]; 
    4     $new_file = "./uploads/" . time() . ".{$type}"; 
    5     if (file_put_contents($new_file, base64_decode(str_replace($result[1], '', $base64)))) { 
    6         echo '新文件保存成功:', $new_file; 
    7     } 
    8 }
