Laravel5.2多图上传的实现以及上传七牛

在模版中引入我们的CSS和JS文件，感谢JS的原作者黑爪爪

1.首先，请去下载对应的组件，百度网盘：

链接: https://pan.baidu.com/s/1QpwA7q7ACv95-8aRTWMwvw 提取码: a9us

2.然后，我们在模板文件中引用

3.模版中的CSS

 

 

4.模版HTML中的图片上传块

    
    

         

    
    
    上传

 

 

5.模版中的JS代码

$(function(){
    $('#test').diyUpload({
    url:"{{URL('some_upload_img')}}",
    success:function( data ) {
        console.log(data);
        $("#pics").after(""); //图片上传成功会执行，就是把图片名字写到CLASS为HIDPIC的隐藏域里

    },
    error:function( err ) {
        console.info( err );    
    }
    });

    $('#show').click(function(){
    
//把CLASS为HIDPIC的VALUE组成用,链接的字符串，放在ID为PIC的隐藏域里
    var b=$('.hidpic').map(function() {

            return $(this).val();
            
        }).get().join(',');
    $('#pics').val(b);
    // alert($('#pics').val());

    });

});

6.接下来，前端我们已经搞定，去控制器中添加方法：

public function someImgUpload(){
    
        if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
        exit; // finish preflight CORS requests here
        }


        if ( !empty($_REQUEST[ 'debug' ]) ) {
            $random = rand(0, intval($_REQUEST[ 'debug' ]) );
            if ( $random === 0 ) {
                header("HTTP/1.0 500 Internal Server Error");
                exit;
            }
        }

        // header("HTTP/1.0 500 Internal Server Error");
        // exit;


        // 5 minutes execution time
        @set_time_limit(5 * 60);

        // Uncomment this one to fake upload time
        usleep(5000);

        // Settings
        // $targetDir = ini_get("upload_tmp_dir") . DIRECTORY_SEPARATOR . "plupload";
        $targetDir = 'uploads/images'; //上传临时地址,可能要更改
        $uploadDir = 'uploads/images'; //上传地址


        $cleanupTargetDir = true; // Remove old files
        $maxFileAge = 5 * 3600; // Temp file age in seconds


        // Create target dir
        if (!file_exists($targetDir)) {
            @mkdir($targetDir);
        }

        // Create target dir
        if (!file_exists($uploadDir)) {
            @mkdir($uploadDir);
        }

        // Get a file name
        // if (isset($_REQUEST["name"])) {
        //     $fileName = $_REQUEST["name"];
        // } elseif (!empty($_FILES)) {
        //     $upfile=@$_FILES[$inputName];
        //     $fileName = $_FILES["file"]["name"];
        // } else {
        //     $fileName = uniqid("file_");
        // }
        $fileName = @$_FILES["file"]["name"];
        $fileInfo=pathinfo($fileName);
        $extension=$fileInfo['extension'];
        $fileName=date("YmdHis").mt_rand(1000,9999).'.'.$extension;


        $md5File = @file('md5list.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
        $md5File = $md5File ? $md5File : array();

        if (isset($_REQUEST["md5"]) && array_search($_REQUEST["md5"], $md5File ) !== FALSE ) {
            die('{"jsonrpc" : "2.0", "result" : null, "id" : "id", "exist": 1}');
        }

        $filePath = $targetDir . DIRECTORY_SEPARATOR . $fileName;
        $uploadPath = $uploadDir . DIRECTORY_SEPARATOR . $fileName;

        // Chunking might be enabled
        $chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0;
        $chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 1;


        // Remove old temp files
        if ($cleanupTargetDir) {
            if (!is_dir($targetDir) || !$dir = opendir($targetDir)) {
                die('{"jsonrpc" : "2.0", "error" : {"code": 100, "message": "Failed to open temp directory."}, "id" : "id"}');
            }

            while (($file = readdir($dir)) !== false) {
                $tmpfilePath = $targetDir . DIRECTORY_SEPARATOR . $file;

                // If temp file is current file proceed to the next
                if ($tmpfilePath == "{$filePath}_{$chunk}.part" || $tmpfilePath == "{$filePath}_{$chunk}.parttmp") {
                    continue;
                }

                // Remove temp file if it is older than the max age and is not the current file
                if (preg_match('/\.(part|parttmp)$/', $file) && (@filemtime($tmpfilePath) < time() - $maxFileAge)) {
                    @unlink($tmpfilePath);
                }
            }
            closedir($dir);
        }


        // Open temp file
        if (!$out = @fopen("{$filePath}_{$chunk}.parttmp", "wb")) {
            die('{"jsonrpc" : "2.0", "error" : {"code": 102, "message": "Failed to open output stream."}, "id" : "id"}');
        }

        if (!empty($_FILES)) {
            if ($_FILES["file"]["error"] || !is_uploaded_file($_FILES["file"]["tmp_name"])) {
                die('{"jsonrpc" : "2.0", "error" : {"code": 103, "message": "Failed to move uploaded file."}, "id" : "id"}');
            }

            // Read binary input stream and append it to temp file
            if (!$in = @fopen($_FILES["file"]["tmp_name"], "rb")) {
                die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');
            }
        } else {
            if (!$in = @fopen("php://input", "rb")) {
                die('{"jsonrpc" : "2.0", "error" : {"code": 101, "message": "Failed to open input stream."}, "id" : "id"}');
            }
        }

        while ($buff = fread($in, 4096)) {
            fwrite($out, $buff);
        }

        @fclose($out);
        @fclose($in);

        rename("{$filePath}_{$chunk}.parttmp", "{$filePath}_{$chunk}.part");

        $index = 0;
        $done = true;
        for( $index = 0; $index < $chunks; $index++ ) {
            if ( !file_exists("{$filePath}_{$index}.part") ) {
                $done = false;
                break;
            }
        }
        if ( $done ) {
            if (!$out = @fopen($uploadPath, "wb")) {
                die('{"jsonrpc" : "2.0", "error" : {"code": 102, "message": "Failed to open output stream."}, "id" : "id"}');
            }

            if ( flock($out, LOCK_EX) ) {
                for( $index = 0; $index < $chunks; $index++ ) {
                    if (!$in = @fopen("{$filePath}_{$index}.part", "rb")) {
                        break;
                    }

                    while ($buff = fread($in, 4096)) {
                        fwrite($out, $buff);
                    }

                    @fclose($in);
                    @unlink("{$filePath}_{$index}.part");
                }

                flock($out, LOCK_UN);
            }
            @fclose($out);
        }

        // Return Success JSON-RPC response
        // die('{"jsonrpc" : "2.0", "result" : null, "id" : "id");
        //向模板输出文件名
        // echo $fileName;
        $data=array('pic'=>$fileName);
        return response()->json($data); //不用框架就用echo json_encode()
    }

7.别忘了注册路由（别忘了去VerifyCsrfToken里面给这个路由加权限，否则Post过不去）

 Route::post('some_upload_img','UploadController@someImgUpload'); //POST方式才行

这步完成以后，就基本上大功告成了，在这里可以试试是否能上传成功。上传成功后如下图所示。

8.最后，上传后的处理，也就是往数据库里插入的时候，需要把,分成一条一条的，逐条插入，中间用到了我自定义的函数uptoQiniu()，目的是把本地的文件传至七牛服务器，这个函数具体怎么用，我之前的文章里有讲，在这里不再赘述。

    public function store(){

		if(Input::get('pics') && Input::get('pics')!=''){
			$source=Input::get('pics');
			$hello = explode(',',$source); 

			for($i=0;$ipic = qiniu_prefix().$hello[$i]; //这里是上传七牛，如果不用七牛就光要后面的$hello[$i]
                    $new_pic->save();
			}
			
								
		}
		return Redirect::to("/admin/picture");

    }
