在Laravel 4中上传多个文件 [英] Upload multiple files in Laravel 4

问题描述

这是我用于上传多个文件的控制器代码，我正在从Google Chrome上的邮递员" rest API客户端传递密钥和值.我正在从邮递员添加多个文件，但只有1个文件正在上传.

Here is my controller code for uploading multiple files and I am passing key and value from 'postman' rest API client on Google Chrome. I am adding multiple files from postman but only 1 file is getting upload.

public function post_files() {
    $allowedExts = array("gif", "jpeg", "jpg", "png","txt","pdf","doc","rtf","docx","xls","xlsx");
    foreach($_FILES['file'] as $key => $abc) {
        $temp = explode(".", $_FILES["file"]["name"]);
        $extension = end($temp);
        $filename= $temp[0];
        $destinationPath = 'upload/'.$filename.'.'.$extension;

        if(in_array($extension, $allowedExts)&&($_FILES["file"]["size"] < 20000000)) {
            if($_FILES["file"]["error"] > 0) {
                echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
            }
            if (file_exists($destinationPath)) {
                echo $filename." already exists. ";
            } else {
                $uploadSuccess=move_uploaded_file($_FILES["file"]["tmp_name"],$destinationPath);
                if( $uploadSuccess ) {
                    $document_details=Response::json(Author::insert_document_details_Call($filename,$destinationPath));
                    return $document_details; // or do a redirect with some message that file was uploaded
                // return Redirect::to('authors')
                } else {
                    return Response::json('error', 400);
                }
            }
        }
    }  
}

我也尝试过此代码，但它会向我返回临时文件夹中文件的位置

I have tried this code also but it returns me location of a file in temporary folder

$file = Input::file('file');
            echo count($file);

和 echo count($_FILES['file']); 总是让我返回5.有人可以告诉我为什么吗?

and echo count($_FILES['file']); returns me always 5.Can anyone tell me why?

以及为什么foreach(Input::file('file') as $key => $abc)给出错误的无效参数

and why foreach(Input::file('file') as $key => $abc) gives the error invalid arguments

推荐答案

不使用任何API，但这可能会概述该原理.

Not using any API, but this might outline the principle.

我设置了这个route.php文件，whick将帮助您进行上传测试.

I set up this routes.php file, whick will help you with upload test.

routes.php

// save files
Route::post('upload', function(){
    $files = Input::file('files');

    foreach($files as $file) {
                // public/uploads
        $file->move('uploads/');
    }
});

// Show form
Route::get('/', function()
{
    echo Form::open(array('url' => 'upload', 'files'=>true));
    echo Form::file('files[]', array('multiple'=>true));
    echo Form::submit();
    echo Form::close();
});

请注意输入名称files []::如果要上传相同名称的多个文件，请同时加上方括号.

Notice the input name, files[]: If uploading multiple files under the same name, include brackets as well.
