I tried creating a script to upload multiple photos, rename photo, and add database entry. The database filename entry is correct however the image upload filename is compounding the jpg name.

ie. Database entry is correctly naming files: photo_1, photo_2, photo_3

The files are being uploaded named incorrectly: photo_1.jpg, photo_1.jpgphoto_2.jpg, photo_1.jpgphoto_2.jpgphoto_3.jpg

Not sure how to resolve this as my database entry is correct.

    <?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/>';
        }
    }
}
?>

  • Stop what you are doing, NOW. You are using a deprecated, unmaintained, and insecure database API. Alternatives like PDO have been available for more than a decade. See http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php – miken32 Feb 20 '17 at 04:22
  • To help people answering your question, may I suggest two things : 1- Format the code you post to be more readable. 2- Tell what you expect as result (the final name that should be gotten, even if I may get it from your code, it is always good to be explicit). – Master DJon Feb 20 '17 at 04:24

Your problem is with this line in your for loop:

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

This code essentially says "Append the new filename to the previous value", which obviously is not what you want.

To fix, just remove the $target_path on the right of the =:

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

  • thanks! Worked like a charm, much appreciated. I am not very skilled at php. I guess i will have to figure out how to switch to mysqli. – Jason Feb 20 '17 at 05:48
