Question

我一直在努力让这个单按钮上传工作，我已经尝试了几种方法来提交上传，这个我似乎已经工作到了php的点，但后来在PHP的东西似乎不喜欢提交，没有js这作为常规选择文件和上传，但很快我添加js（似乎工作）PHP然后不起作用。

我完全混淆了为什么会发生这种情况！

任何建议表示感谢！

上传表单

<form name="form" method="POST" enctype="multipart/form-data"  action="updateProfilePic_script.php">    
                                    <div class="update_header_pic"> 

 <input type = 'button' value = 'Choose image' 
                                   onclick ="javascript:document.getElementById('Photo').click();">
                                  <input id='Photo' type='file' style='visibility: hidden;' name='Photo' onchange='submit();'/>


                                    </div>
                                </form>

php

<?

    $user = $_SESSION['username'];
                        $hostname = "localhost";

                        $filePath = $uploadDir . $fileName;
                        $result = move_uploaded_file($tmpName, $filePath);
                        if (!$result) {
                        echo "Error uploading file";
                        exit;
                        }
                        if(!get_magic_quotes_gpc())
                        {
                        $fileName = addslashes($fileName);
                        $filePath = addslashes($filePath);
                        }
                        $query = "INSERT INTO $db_table ( Image , username , datetime , filesize , filetype ) VALUES ('$filePath' , '$user' , '$date' , '$fileSize' , '$fileType' )";
                        mysql_query($query) or die('Error, query failed');

                        header('Location: edit_myProfile.php');

                        }



                        ?>

在您的HTML表单中没有[input type=submit]，那么为什么在您的PHP代码中执行：

if(isset($_POST['submit'])) {
//...
//..
}

您只需将其更改为：

if(isset($_FILES['Photo'])) {
 //the your uploading procedure
}
