Javascript 无法将图像存储在本地文件夹中

我正在使用PHP、jQuery、AJAX和MySql。我正在使用move\u upload\u file功能将图像存储在本地文件夹中，并将图像路径存储在数据库中。我的映像路径正在存储n DB。但是图像本身不会进入本地文件夹

upload.php

function AddPhtImage($varArray,$tablename ){

    if(!$this->DBLogin())
    {
        $this->HandleError("Database login failed!");
        return false;
    }      
    $a=$varArray['upvid'];
    $file = str_replace( "\\", '/', $a );
    $ofile = basename( $file );
        $oofile ="myfolder/".$ofile;
    $date = date('m/d/Y', time()); 

    $qry = "INSERT INTO $tablename ( image ) VALUES ('".$oofile."') ";
    $result = mysql_query($qry,$this->connection);
    return $result;
 }

 <form id="mmyForm" action="mypage.php" method="POST" enctype="multipart/form-data">

 <input type="file" id="photo" name="photo">
 <?php
 $output_dir = "myfolder/";
 if(isset($_FILES["photo"]))
 {
     if ($_FILES["photo"]["error"] > 0)
     {
         $result['error'] = "Error: " . $_FILES["file"]["error"] . "<br>";
     }
     else
     {                                          
         move_uploaded_file( $_FILES["photo"]["tmp_name"],$output_dir. $_FILES["photo"]["name"] );
         $result['success'] = "Uploaded Document :".$_FILES["photo"]["name"];           
     }
 }
 else
     {
         $result['error'] = 'upload document';
     }                                  
    ?>

    </form>

使用数组

if(isset($_REQUEST['disp']))
{
   array_pop( $_POST );
   $upload_type= $media->AddPhtImage($_POST, 'mytable');
   return true; 
}

function.php

function AddPhtImage($varArray,$tablename ){

    if(!$this->DBLogin())
    {
        $this->HandleError("Database login failed!");
        return false;
    }      
    $a=$varArray['upvid'];
    $file = str_replace( "\\", '/', $a );
    $ofile = basename( $file );
        $oofile ="myfolder/".$ofile;
    $date = date('m/d/Y', time()); 

    $qry = "INSERT INTO $tablename ( image ) VALUES ('".$oofile."') ";
    $result = mysql_query($qry,$this->connection);
    return $result;
 }
