Angularjs - 文件上传用PHP [英] Angularjs - File upload with php

问题描述

我花了几天找一个相当简单的集成，它包括一个基本的PHP服务器端脚本angularjs文件上传的方法。

I have spent days looking for a fairly simple integration of angularjs file upload method that includes a basic php server side script..

我需要一个简单的表格一个字段和文件上传上传。

I need a simple form one field and file upload upload.

所有的例子，我觉得要么严重依赖jQuery的，或者如果他们似乎喜欢的东西，我可以用自己的榜样是完全不清楚，杂乱。

All examples I find are either heavily relying of jQuery or if they seem like something I could use their "examples" are completely unclear and messy.

这两个例子（如果我能想出​​如何与PHP集成）将解决我的难题。

These two examples (if I could figure out how to incorporate with PHP) would solve my puzzle..

此页面上例5
http://ng-upload.eu01.aws.af.cm/

和此页面上的例子是我真的想了很多..
http://angular-file-upload.appspot.com/

And the example on this page is one I really like a lot.. http://angular-file-upload.appspot.com/

有人能带来更多的光线进入这对我来说..我真的想看到一个一个输入归档和尽可能简单的角度和php code一个文件上传，如果这样的事情存在某处。

Could someone bring more light into this for me.. I would really like to see a one input filed and one file upload with as simple as possible angular and php code if such thing exists somewhere.

我将很高兴来实现这个 http://twilson63.github.io/ngUpload/ 或 http://angular-file-upload.appspot.com/

I would be happy to implement this http://twilson63.github.io/ngUpload/ or http://angular-file-upload.appspot.com/

如果这是我的PHP

$fname = $_POST["fname"];
if(isset($_FILES['image'])){
    $errors= array();
    $file_name = $_FILES['image']['name'];
    $file_size =$_FILES['image']['size'];
    $file_tmp =$_FILES['image']['tmp_name'];
    $file_type=$_FILES['image']['type'];   
    $file_ext = strtolower(pathinfo($file_name, PATHINFO_EXTENSION));
    $extensions = array("jpeg","jpg","png");        
    if(in_array($file_ext,$extensions )=== false){
     $errors[]="image extension not allowed, please choose a JPEG or PNG file.";
    }
    if($file_size > 2097152){
    $errors[]='File size cannot exceed 2 MB';
    }               
    if(empty($errors)==true){
        move_uploaded_file($file_tmp,"images/".$file_name);
        echo $fname . " uploaded file: " . "images/" . $file_name;
    }else{
        print_r($errors);
    }
}
?>

和这是我基本的HTML

and this my basic html

<form action="" method="POST" enctype="multipart/form-data">
    <input type="text" name="fname" />
    <input type="file" name="image" />
    <input type="submit"/>
</form>

我怎么能解决这个（干净）？应我的控制器和调整后的HTML是什么样的？

How could I approach this (cleanly)? What should my controller and adjusted html look like?

推荐答案

如果您使用角文件-upload
你可以做最那些pre-验证像检查文件大小或类型与NGF-MAX尺寸或NGF图案指示的客户端。

If you use angular-file-upload You can do most of those pre-validation on the client side like checking the file size or type with ngf-max-size or ngf-pattern directives.

Upload.upload（）将发送POST的multipart / form-data的请求到服务器，以便 $ _ FILES ['文件'] 应包含上传的文件。

Upload.upload() will send a POST multipart/form-data request to the server so $_FILES['file'] should contain the uploaded file.

HTML

<div ng-controller="MyCtrl">
  <input type="text" name="username" ng-model="username"/>
  <input type="file" ngf-select="onFileSelect($file)" ngf-pattern="'image/*'" ngf-max-size="2M">
</div>

JS：

//inject angular file upload directives and service.
angular.module('myApp', ['ngFileUpload']);

var MyCtrl = [ '$scope', 'Upload', function($scope, Upload) {
  $scope.onFileSelect = function(file) {
    if (!file) return;
    Upload.upload({
        url: '/upload.php'
        data: {file: file, username: $scope.username}
      }).then(function(resp) {
        // file is uploaded successfully
        console.log(resp.data);
      });    
  };
}];

upload.php的

upload.php

$fname = $_POST["fname"];
if(isset($_FILES['image'])){
    //The error validation could be done on the javascript client side.
    $errors= array();        
    $file_name = $_FILES['image']['name'];
    $file_size =$_FILES['image']['size'];
    $file_tmp =$_FILES['image']['tmp_name'];
    $file_type=$_FILES['image']['type'];   
    $file_ext = strtolower(pathinfo($file_name, PATHINFO_EXTENSION));
    $extensions = array("jpeg","jpg","png");        
    if(in_array($file_ext,$extensions )=== false){
     $errors[]="image extension not allowed, please choose a JPEG or PNG file.";
    }
    if($file_size > 2097152){
    $errors[]='File size cannot exceed 2 MB';
    }               
    if(empty($errors)==true){
        move_uploaded_file($file_tmp,"images/".$file_name);
        echo $fname . " uploaded file: " . "images/" . $file_name;
    }else{
        print_r($errors);
    }
}
?>
