tp5中利用uploadify上传图片

1.首先需要安装一下uploadify，安装位置如图：

2. 在页面中引入css、js代码

<link rel="stylesheet" type="text/css" href="__STATIC__/admin/uploadify/uploadify.css" />
{load href="__STATIC__/admin/uploadify/jquery.uploadify.min.js" /}
{load href="__STATIC__/admin/js/image.js" /}

image.js:

$(function(){
    $("#file_upload").uploadify({
        swf  :  swf,
        uploader  :  image_upload_url,
        buttonText  : '图片上传',
        fileTypeDesc: 'Image files',
        fileObjName: 'file',
        fileTypeExts: '*.gif;*.jpg;*.png',
        onUploadSuccess: function(file, data, response){
            if(response){
                var obj = JSON.parse(data);
                $('#upload_org_code_img').attr("src", obj.data);
                $('#file_upload_image').attr("value", obj.data);
                $('#upload_org_code_img').show();
            }
        }
    });
});

3.页面中需要有个容器

<input id="file_upload"  type="file" multiple="true" >
<img style="display: none" id="upload_org_code_img" src="" width="150" height="150">
<input id="file_upload_image" name="image" type="hidden" multiple="true" value="">

input用来上传图片
img用来显示上传成功后的缩略图

4.定义inage.js中的swf image_upload_url

<script>
    swf = '__STATIC__/admin/uploadify/uploadify.swf';
    image_upload_url = "{:url('image/upload')}";
</script>

5.控制器

image控制器下的upload方法

public function upload(){
        $file = Request::instance()->file('file');
        //把图片上传到指定的文件夹中
        $info = $file->move('upload');

        if($info && $info->getPathname()){
            $data = [
                'status' => 1,
                'message' => 'OK',
                'data' => '/'.$info->getPathname(),
            ];
            echo json_encode($data);exit;
        }

        echo json_encode(['status' => 0, 'message' => '上传失败']);
    }

提示：使用uploadify时需要浏览器开启flash
