Question

我尝试创建一个脚本来上传多张照片，重命名照片和添加数据库条目。数据库文件名条目是正确的，但图像上传文件名正在混合jpg名称。

即。数据库输入正确命名文件：photo_1，photo_2，photo_3

文件上传的名称不正确：photo_1.jpg，photo_1.jpgphoto_2.jpg，photo_1.jpgphoto_2.jpgphoto_3.jpg

由于数据库条目正确无法确定如何解决此问题。

    <?php
if (isset($_POST['submit'])) {
    $j = 0; //Variable for indexing uploaded image 
    $image_post_id = $_POST["image_post_id"];

    $target_path = "uploads/"; //Declaring Path for uploaded images
    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array




        $validextensions = array("jpeg", "jpg", "png", "JPG", "PNG", "JPEG");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 

        $file_extension = end($ext); //store extensions in the variable





        //MYSQL Handling

            mysql_query( "INSERT INTO post_images(`image_filename`, `image_post_id`) VALUES('0', '".addslashes($image_post_id)."')" );
                            $new_id = mysql_insert_id();

                            $target_path = $target_path . "post_". $new_id . "." . strtolower($ext[count($ext) - 1]);//set the target path with a new name of image
                            mysql_query( "UPDATE post_images SET image_filename='post_".addslashes($new_id).".".strtolower($ext[count($ext) - 1])."' WHERE image_id='".addslashes($new_id)."'" );












        $j = $j + 1;//increment the number of uploaded images according to the files in array       

      if (($_FILES["file"]["size"][$i] < 1000000) //Approx. 100kb files can be uploaded.
                && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
                echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
            } else {//if file was not moved.
                echo $j. ').<span id="error">please try again!.</span><br/><br/>';
            }
        } else {//if file size and file type was incorrect.
            echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
        }
    }
}
?>

问题出在for循环中的这一行：

$target_path = $target_path . "post_". $new_id . "." . strtolower($ext[count($ext) - 1]);

此代码基本上说＆＃34; 将新文件名附加到上一个值＆＃34;，这显然不是您想要的。

要解决此问题，只需移除$target_path：

右侧的=即可

$target_path = "post_". $new_id . "." . strtolower($ext[count($ext) - 1]);
