Move_upload_file() 无法打开流并且无法移动文件

Question

在文件夹中上传图像文件时出现一些问题，如果文件存在，则通过当前上传文件移动它... 第一次上传很好，但在移动过程中显示一些错误

<?php include_once('../includes/config.php');

   if(isset($_POST['add_code']))
   {
       if (($_FILES['photo']['name']!="")){
           // Where the file is going to be stored
           $target_dir = "manufacturer/";
           $file = $_FILES['photo']['name'];
           $path = pathinfo($file);
           $filename = $path['filename'];
           $ext = $path['extension'];
           $temp_name = $_FILES['photo']['tmp_name'];
           $path_filename_ext = $target_dir.$filename.".".$ext;

           // Check if file already exists
           if (file_exists($path_filename_ext)) {
               echo "Sorry, file already exists.";
           }else{
               move_uploaded_file($temp_name,$path_filename_ext);
               echo "Congratulations! File Uploaded Successfully.";
           }
       }           
       $ititle=$_POST['image_title'];
       $c_=mysqli_query($connection,"INSERT INTO `manufacturer`(`mname`, `mimg`) VALUES ('$ititle','$path_filename_ext')");
//$check_user_data=mysqli_fetch_array($check_user_);
       if($c=true){
        echo '1';
       }
   }
?>

您必须按以下方式验证一些要点。

1) 确保您的表单具有 enctype="multipart/form-data"

2) 请检查您必须创建文件夹的根目录 "manufacturer"

现在我希望您拥有以下文件

form.php 文件

<form name="fileUpload" method="post" id="fileUpload" enctype="multipart/form-data" action="success.php">
    <input type="text" name="image_title">
    <input type="file" name="photo">
    <input type="submit" name="add_code" value="Submit">
</form>

success.php 文件

<?php

if(isset($_POST['add_code'])){
    if (($_FILES['photo']['name']!="")){
        // Where the file is going to be stored
        $target_dir = "manufacturer/";
        $file = $_FILES['photo']['name'];
        $path = pathinfo($file);
        $filename = $path['filename'];
        $ext = $path['extension'];
        $temp_name = $_FILES['photo']['tmp_name'];
        $path_filename_ext = $target_dir.$filename.".".$ext;

        // Check if file already exists
        if (file_exists($path_filename_ext)) {
            echo "Sorry, file already exists.";
        }else{
           move_uploaded_file($temp_name,$path_filename_ext);
           echo "Congratulations! File Uploaded Successfully.";
       }
    }

    $ititle=$_POST['image_title'];
    $c_=mysqli_query($connection,"INSERT INTO `manufacturer`(`mname`, `mimg`) VALUES ('$ititle','$path_filename_ext')");
    //$check_user_data=mysqli_fetch_array($check_user_);
    if($c=true){
        echo '1';
    }
}
?>

请尝试使用上面列出的代码，我希望它有效。
