Question

我有一张上传图片的表单：

<form action="" method="post" enctype="multipart/form-data">
   <input type="file" name="imgUpload" class="admin_img_txt">
   <input type="submit" value="Upload" name="img01" class="admin_img_btn">
</form>

它使用img01帖子中包含的代码发布到自己。该过程有效，但当我回显$_FILES数组时，我没有文件大小。我上传的图片是我在本地计算机上的有效jpg。它返回

(
[imgUpload] => Array
    (
        [name] => testjpg.jpg
        [type] => image/jpeg
        [tmp_name] => /tmp/php3TxfDe
        [error] => 0
        [size] => 0
    )
)

我已经验证了php.ini文件的设置。它允许最多8mb的文件，这是远远不够的。有任何想法吗？提前谢谢。

编辑：这是php。我并没有把它包含在print_r之前，所以我认为它并不重要。

if(isset($_POST["img01"])) {
    echo '<pre>';
    print_r($_FILES);
    echo  '</pre>';
    $filename = $_FILES["imgUpload"]["name"];
    $file_basename = substr($filename, 0, strripos($filename, '.'));
    $file_ext = substr($filename, strripos($filename, '.'));
    $ven_imgname = "$ven_id" . "_001";
    $newfilename = md5($ven_imgname) . $file_ext;
    $filesize = $_FILES["imgUpload"]["size"];
    $allowed_file_types = array('.jpg','.jpeg','.gif'); 
    if (in_array($file_ext,$allowed_file_types) && ($filesize < 200000)) {
        if (file_exists("../img/venues/$ven_imgname.$file_ext")) {
            echo "You have already uploaded this file - $ven_imgname.$file_ext";
        } else {        
            move_uploaded_file($_FILES["imgUpload"]["temp_name"], "../img/venues/" . $newfilename);
            echo "File uploaded successfully.";     
        }
    } else {
        echo "File upload failed."; 
    }
}
