我正在使用 extjs+PHP[yii 框架]。我正在研究文件上传控制。我有查看代码为-

Ext.define('Balaee.view.kp.dnycontent.Content', 
{
    extend:'Ext.form.Panel',
    requires:[
              'Balaee.view.kp.dnycontent.ContentView'
              ],
    id:'ContentId',
    alias:'widget.Content',
    enctype : 'multipart/form-data', 
    title:'This day in a history',
    items:[
        {
        xtype: 'fileuploadfield',
        hideLabel: true,
        emptyText: 'Select a file to upload...',
        //inputType: 'file',
        id: 'upfile',
        name:'file',
        width: 220
}],

   buttons: [{
        xtype : 'button',
        fieldlabel:'upload',
        action:'upload',
        name:'upload',
        text: 'Upload',
        formBind:'true',
       handler: function() {
            var form = this.up('form').getForm();
            if(form.isValid()){
                form.submit({
                    url: 'index.php/QuestionBank/Qbpaper/getFile',
                    waitMsg: 'Uploading your photo...',
                  //  uploadPath:'/app/model',
                    success: function(fp, o) {
                        Ext.Msg.alert('Success', 'Your photo "' + o.result.file + '" has been uploaded.');
                    }
                });} } }]});

我已经编写了上面的代码来从 extjs4 发送文件。我的服务器端是 PHP [Yii 框架]。在服务器端,我编写了代码来接收这个文件——

public function actiongetFile()
    {
        $fileName = $_FILES['upfile']['name'];
        $fileSize = $_FILES['upfile']['size'];
        $fileType = $_FILES['upfile']['type'];
        $fp      = fopen($fileName, 'r');
        $content = fread($fp, filesize($fileName));
        $content = addslashes($content);
        fclose($fp);
        if(!get_magic_quotes_gpc()){
            $fileName = addslashes($fileName);
        }

但服务器端代码无法正常工作。从 extjs 发送文件时,它给出的错误是-“Ext.Error: You're trying to decode an invalid JSON String: PHP notice Undefined index: upfile” 所以在 php 中如何访问通过 extjs4 发送的文件。请帮我

name:'file'

这 ^ 是您在数组中的文件的索引。

id是内部的,但是name是提交的标签。

试试看。利用:

$_FILES['file']['name']

代替:

$_FILES['upfile']['name']
