这是我的后端代码

<?php
session_start();
include("includes/mysqli_connection.php");

// User is already logged in. Redirect them somewhere useful.
if (!isset($_SESSION['username']))
{
echo "<script>alert('Web Master Says : : Login First :-( !!!')</script>";
echo "<meta http-equiv='refresh' content='2;url=../index.php'>";
exit();
}

else if(!isset($_SESSION['status']) )
{
echo "<script>alert('INTRUDER!!!: :')</script>";
echo "<meta http-equiv='refresh' content='2;url=../index.php'>";
exit();
}

else
{
$admin = $_SESSION['username'];
}

?>

<?php

if(isset($_SESSION['username']))
{
$id = mysqli_real_escape_string($db_conx,htmlspecialchars($_POST['id']));
$Name =  mysqli_real_escape_string($db_conx,htmlspecialchars($_POST['Name']));
$Path = mysqli_real_escape_string($db_conx,htmlspecialchars($_POST['Path']));
$Category = mysqli_real_escape_string($db_conx,htmlspecialchars($_POST['Category']));
$Price = mysqli_real_escape_string($db_conx,htmlspecialchars($_POST['Price']));
$Descr = mysqli_real_escape_string($db_conx,htmlspecialchars($_POST['Descr']));
$Type = mysqli_real_escape_string($db_conx,htmlspecialchars($_POST['Type']));
$Views =  mysqli_real_escape_string($db_conx,htmlspecialchars($_POST['Views']));
}

else
{
 echo "ERROR!!!";
 $id = "";
}

$updateuser = "UPDATE jewellery SET prodname='$Name', path='$Path',  category='$Category', price='$Price', descr='$Descr', type='$Type',  noviews='$Views' WHERE id='$id'";

$query = mysqli_query($db_conx,$updateuser);

if($query)
{
    echo "<script>alert('Successfully Updated!')</script>";
    echo "<script>window.location.href='viewprod.php';</script>";
}

else
{
    echo "Could not update data";
    echo "<script>window.location.href='viewprod.php';</script>";
}
?>

主要问题是关于将文件上传到文件夹并将路径保存在数据库中，在此脚本中我可以保存路径但无法上传文件任何人都可以帮助我解决它

最佳答案 

<?php
 // Included configuration file in our code.

include ("includes/mysqli_connection.php");

$prodname = mysqli_real_escape_string($db_conx,$_POST['Name']);
$category = mysqli_real_escape_string($db_conx,$_POST['Category']);
$price = mysqli_real_escape_string($db_conx,$_POST['Price']);
$desc = mysqli_real_escape_string($db_conx,$_POST['Desc']);
$type = mysqli_real_escape_string($db_conx,$_POST['Type']);
$views = mysqli_real_escape_string($db_conx,$_POST['Views']);
$view_target_path='';
 function GetImageExtension($imagetype)
     {
       if(empty($imagetype)) return false;
       switch($imagetype)
       {
           case 'image/bmp': return '.bmp';
           case 'image/gif': return '.gif';
           case 'image/jpeg': return '.jpg';
           case 'image/png': return '.png';
           default: return false;
       }
     }
if (!empty($_FILES["Path"]["name"])) {

    $file_name=$_FILES["Path"]["name"];
    $temp_name=$_FILES["Path"]["tmp_name"];
    $imgtype=$_FILES["Path"]["type"];
    $ext= GetImageExtension($imgtype);
    $imagename=date("d-m-Y")."-".$price.time().$ext;
        $view_target_path="Photos/moses/".$imagename;
        $target_path="../Photos/moses/".$imagename;
 if(move_uploaded_file($temp_name, $target_path)) {
       // $name=$_REQUEST['name'];

//      mysql_query($query_upload) or die("error in $query_upload == ---->  ".mysql_error()); 
//            echo 'done';

    }else{

     exit("Error While uploading image on the server");
 }

    }
    $sql = "SELECT * FROM jewellery WHERE prodname = '$prodname'";

  $result = mysqli_query($db_conx, $sql);

if(!mysqli_num_rows($result))
{   
    $insertSQL = "INSERT INTO jewellery (prodname, path, category, price, descr, type, noviews)
            VALUES ('$prodname', '$view_target_path', '$category', '$price', '$desc', '$type', '$views')";

    mysqli_query($db_conx, $insertSQL);

    if($insertSQL)
    {
        echo "<script>alert('Successfully Added!')</script>";

        echo "<script>window.location.href='viewprod.php'</script>";
    }
    else
    {
        echo 'An error occured while uploading the entry to database. Please try again later.';
    }
}

else
{
    echo "<font color='red'>Sorry This Product already exists!</font>";
    echo "<script>alert('Redirecting...')</script>";
    echo "<script>window.location.href='newprod.php'</script>";
}

// Close your database connection
mysqli_close($db_conx);
?>
