Upload+Resize Database mysql

Jeg har et problem med noget Upload resize, jeg kan i princippet godt finde ud af at uploade billed stien til min database, men problemet opstår idet den smider stierne ind i alle tabellerne.

Til den heldige vinder som kan redde ud i trådende, er der 300 point.

Her er min kode:

<?php

$conn = mysqli_connect("medieskolerne.dk","hfelev15","hfelev15","hfelev15");

# Function to open any kind of image
function open_image ($file){
    # JPEG:
    $im = @imagecreatefromjpeg($file);
    if ($im !== false) {return $im;};
    # GIF
    $im = @imagecreatefromgif($file);
    if ($im !== false) {return $im;};
    # PNG
    $im = @imagecreatefrompng($file);
    if ($im !== false) {return $im;};
    # GD File:
    $im = @imagecreatefromgd($file);
    if ($im !== false) {return $im;};
    # GD2 File:
    $im = @imagecreatefromgd2($file);
    if ($im !== false) {return $im;};
    # WBMP
    $im = @imagecreatefromwbmp($file);
    if ($im !== false) {return $im;};
    # XBM
    $im = @imagecreatefromxbm($file);
    if ($im !== false) {return $im;};
    # XPM
    $im = @imagecreatefromxpm($file);
    if ($im !== false) {return $im;};
    # Try and load from string:
    $im = @imagecreatefromstring(file_get_contents($file));
    if ($im !== false) {return $im;};
    return false;
};

# File-field name
$file_field_name = "fil";
# Submit-field name
$submit_field_name = "submit";

# Allowed file-types
$allow_types = array('jpg','gif','png');
# Directory where files will be uploaded to
$upload_dir = "thumbs/";

# Check if submit-button is clicked
if (isset($_POST[$submit_field_name])){
    #Check if there is a file
    if (is_uploaded_file($_FILES[$file_field_name]['tmp_name'])){
        # Get file extension
        $file_ext = strtolower(pathinfo($_FILES[$file_field_name]['name'], PATHINFO_EXTENSION));
        $billede2 = date('dmyHis').mt_rand().".".$file_ext;
       
        # Check if file extension is allowed
        if (in_array($file_ext, $allow_types)){
            # Move file to the upload directory
            if (move_uploaded_file($_FILES[$file_field_name]['tmp_name'], $upload_dir.$billede2)){

$image_path_new = "thumbs/thumbs_".$billede2;

$image = open_image($image_path);  //Open the image

if($image === false){
    echo "Ikke gyldigt fil format. Kun JPG, GIF & PNG er tilladt.";
}else{
    # Orginal file size
    $width = imagesx($image);
    $height = imagesy($image);
   
    # New file size
    $width_new = 200;
    $height_new = $height * ($width_new / $width);
   
    # Resize / resample the image
    $image_resized = imagecreatetruecolor($width_new,$height_new);
    imagecopyresampled($image_resized,$image,0,0,0,0,$width_new,$height_new,$width,$height);
   
    # Check if the images has been resized
    if(!isset($image_resized)){
        $image_resized = $image;
    };
   
    # Save the image
    imagejpeg($image_resized,$image_path_new);
   
    # Display resized image
    //echo "<img src='".$image_path_new."' />";

   
};

$minQuery = "UPDATE skoleopgaver SET billede2= '$image_path_new'  WHERE '$billede2'" or die(mysqli_error());
                                                                                                       
$result=mysqli_query($conn,$minQuery) or die(mysqli_error($conn));                                                                                                       

                //echo "<br>File $billede2 uploaded<br>";
            }else{
                echo "Error occoured while moving the file";
               
            };
        }else{
            # File type is allowed
            echo "File type is not allowed";
           
        };

      echo "Select a file for upload";
     
  };
};
mysqli_close($conn);

header("location:edit.php?p=1");
?>

<form action="upload_resize.php" method="POST" enctype="multipart/form-data">
<input type="file" name="fil" />
<input type="submit" name="submit" value="Upload" />
</form>

Håber der er en som kan hjælpe mig :-)
