我收到错误:当我尝试上传任何文件时,不允许您尝试上传的文件类型.

if(!empty($_FILES['proof_of_purchase']['name'])) {
    $config['upload_path'] = './uploads/invoices/';
    $config['allowed_types'] = 'gif|jpg|jpeg|png|pdf|bmp';
    $config['max_size'] = '3000';
    $this->load->library('upload', $config);

      // if there was an error, return and display it
    if (!$this->upload->do_upload('proof_of_purchase'))
    {
        $data['error'] = $this->upload->display_errors();
        $data['include'] = 'pages/classic-register';
    } else {
        $data['upload_data'] = $this->upload->data();
        $filename = $data['upload_data']['file_name'];
    }
}

我尝试过很多不同的文件 - 主要是gif和jpeg,每次都会得到同样的错误.

后续代码var_dump($ _ FILES); 给我:

array(1) { ["proof_of_purchase"]=> array(5) { ["name"]=> string(28) "2010-12-04_00019.jpg" ["type"]=> string(10) "image/jpeg" ["tmp_name"]=> string(19) "D:\temp\php2BAE.tmp" ["error"]=> int(0) ["size"]=> int(58054) } } 

我检查了mime配置,它包含正确的东西.例:

'jpeg'  =>  array('image/jpeg', 'image/pjpeg'),
'jpg'   =>  array('image/jpeg', 'image/pjpeg'), …

我试图找出如何访问基本上多维JSON数组中的数据.

我的jQuery AJAX请求如下所示:

 $("#login-form").submit(function(e) {
 e.preventDefault();
 $.ajax({
   type: 'POST',
   url: '/ajax/login',
   data: 'email='+$("#email").val()+'&password='+$("#password").val(),
   success: function(data){

     // FIRE ALERT HERE        
     alert(data.firstname);

     },
     dataType: 'json'
  });
});

这就是我要回来的.用户帐户详细信息,以及他们针对其帐户的产品列表.

{
    "logged_in":true,
    "firstname":"Joe",
    "surname":"Bloggs",
    "Full_name":"Joe Bloggs",
    "email":"email@website.com",
    "phone":"+123456789",
    "website":"",
    "age":"26-35",
    "street":"1 Street Ave",
    "city":"Townland",
    "state":"NA",
    "postcode":"1234",
    "country":"Australia",
    "products":2,
    "0":{
        "product_no":"1087",
        "customer":"2",
        "bought_from":"1",
        "date_of_purchase":"2011-04-08",
        "method":"instore",
        "invoice":"0",
        "current":"1"
    },
    "1":{
        "product_no":"24",
        "customer":"2",
        "bought_from":"1",
        "date_of_purchase":"2011-04-08",
        "method":"instore",
        "invoice":"0",
        "current":"1"
    }
}

正如你所看到的,我正在警告第一个名字,这很好.我可以通过使用data.key访问第一维中的所有内容,但我不知道如何我需要索引下一个维度.显然我想以某种方式展示每个产品.

建议是最受欢迎的.
