Question

我试图从2小时开始调试代码，但在这里找不到问题。此代码不上传任何文件！它也没有显示任何错误。好像服务器根本没有收到文件！

这是html部分

<form action="?" method="post" enctype="multipart/form-data" name="form1" id="form1">
  <label>Select file: (Max size: 2mb)</label>
  <input type="file" name="xls_file" id="xls_file" /> <input type='hidden' value='55' name='yo' />
  <input type="submit" name="submit" id="submit" value="Submit" />
</form>

这是PHP部分

    if(isset($_FILES['xls_file'])) {
    if ($_FILES['xls_file']['error'] !== UPLOAD_ERR_OK) {
   die("Upload failed with error code " . $_FILES['xls_file']['error']);
    }}

if(isset($_FILES['xls_file'])){
$file_name = $_FILES['xls_file']['name'];
$allowed =  array('xls','xlsx','csv');
$ext = pathinfo($file_name, PATHINFO_EXTENSION);

$file_size =$_FILES['xls_file']['size'];
$file_tmp =$_FILES['xls_file']['tmp_name'];
$file_type=$_FILES['xls_file']['type'];

//check for valid file
if(!in_array($ext,$allowed)) {
    echo "Invalid file type.";
    exit;
    }

//check for file size
if(($file_size/1000) > 2100){
    echo "File size greater than allowed limit. Kindly choose a small file. ";
    exit;
    }

move_uploaded_file($file_tmp,"./".str_replace(array('"',"'","\\","=","<",">","`",";"), '', $file_name));
$uploaded = true;
}

这是完整的代码

    <?php
$G_POST = str_replace(array('"',"'","\\","=","<",">","`",";"), '', $_POST);
$G_GET = str_replace(array('"',"'","\\","=","<",">","`",";"), '', $_GET);


if($G_POST[filename])
        $uploaded = true;

    if(isset($_FILES['xls_file'])) {
    if ($_FILES['xls_file']['error'] !== UPLOAD_ERR_OK) {
   die("Upload failed with error code " . $_FILES['xls_file']['error']);
    }}

    if(isset($_FILES['xls_file'])){
    $file_name = $_FILES['xls_file']['name'];
    $allowed =  array('xls','xlsx','csv');
    $ext = pathinfo($file_name, PATHINFO_EXTENSION);

    $file_size =$_FILES['xls_file']['size'];
    $file_tmp =$_FILES['xls_file']['tmp_name'];
    $file_type=$_FILES['xls_file']['type'];

    //check for valid file
    if(!in_array($ext,$allowed)) {
        echo "Invalid file type.";
        exit;
        }

    //check for file size
    if(($file_size/1000) > 2100){
        echo "File size greater than allowed limit. Kindly choose a small file. ";
        exit;
        }

    move_uploaded_file($file_tmp,"./".str_replace(array('"',"'","\\","=","<",">","`",";"), '', $file_name));
    $uploaded = true;
    }

我很有经验。但从未遇到任何此类问题。

Answer 1

正如@RahulPatel指出的那样，事情是jquery.mobile在处理表单数据时使用ajax。文件不能与ajax一起提交。所以我们需要告诉j.mobile关闭这个表单的ajax。因此，我们需要在表单定义中添加以下内容

data-ajax="false"

所以代码将是

<form action="" method="post" enctype="multipart/form-data" name="form1" id="form1" data-ajax="false">
