Make a thumb image

[sorin21us]

I have this demo on my website, where you login with demo and demo, but when I upload an image the script doesn't make the thumb. I find the original photo in the folder from that profile, but I can't see the error for thumb. I see only the broken link icon for thumb and if you click on that you will see the original image.

If there is someone who can give me a hand I will appreciate that.

This is the code for adding images and making thumbs:

<?php
session_start();
include "db_connect.php";

if($_SESSION['id'])
{
    $sql = "SELECT username FROM `users` WHERE `id`='".$_SESSION['id']."'";
    $res = mysql_query($sql) or die(mysql_error());
    
    if(mysql_num_rows($res) != 1)
    {
        session_destroy();
        echo "<script language=\"Javascript\" type=\"text/javascript\">document.location.href='index.php'</script>";
    }
    else
    {
    $row = mysql_fetch_assoc($res);
    
    $title = protect($_POST['title']);
    
    if(!$title)
    {
        echo "<script language=\"Javascript\" type=\"text/javascript\">
                alert(\"You must choose a title for your picture!\")
                document.location.href='profilecp.php'</script>";
        
    }
    
    $target = $row['username'];
    if(!is_dir($target)) @mkdir($target);
    $target = $target . '/pics';
    
    if(!is_dir($target)) @mkdir($target);
    
        $target = $target."/".basename($_FILES['pics']['name']) ;
        $size = $_FILES['pics']['size'];
        $pic = $_FILES['pics']['name'];
        $type = $_FILES['pics']['type'];
                            
            $sql2= "INSERT INTO `user_photos` (`profile_id`,`title`,`size`,`type`,`reference`)
            VALUES ('".$_SESSION['id']."','$title','$size','$type','$pic'); ";
            
            $res2 = mysql_query($sql2) or die(mysql_error());

                if(move_uploaded_file($_FILES['pics']['tmp_name'], $target))
                {
                    echo "<script language=\"Javascript\" type=\"text/javascript\">
                    alert(\"Your picture has been uploaded\")
                    document.location.href='profilecp.php'</script>";
                }
                else
                {
                    echo "<script language=\"Javascript\" type=\"text/javascript\">
                    alert(\"There was an error, try again\")
                    document.location.href='profilecp.php'</script>";
                }
            
        
        $target2 = $row['username'];
        $target2 = $target2 . '/pics';
        $target2 = $target2 . '/thumbs';
        if(!is_dir($target2)) @mkdir($target2);
        $target2 = $target2."/".basename($_FILES['pics']['name']) ;
        createthumb($target,$target2,150,150);
        
    }
}else echo "<script language=\"Javascript\" type=\"text/javascript\">document.location.href='index.php'</script>";

?>

Are the 'target' directories being created? Are you using the full path to the 'target' directory/file? Is createthumb your function? Could we see the code to check it as well?

In the code that's above I create with mkdir the pics dir that has inside the thumb dir. Only with that code I make dir.
The path is correct: usename/pics/thumbs

                $target2 = $row['username'];
        $target2 = $target2 . '/pics';
        $target2 = $target2 . '/thumbs';
        if(!is_dir($target2)) @mkdir($target2);
        $target2 = $target2."/".basename($_FILES['pics']['name']) ;
        createthumb($target,$target2,150,150);

We'll be needing to see the code for your createthumb function as well.

What I meant was, can you see the directories via FTP to see if they were created? With the full path, I meant '/server/path/to/root/usename/pics/thumbs/'.

We'll be needing to see the code for your createthumb function as well.

This is the function:

function createthumb($name,$filename,$new_w,$new_h)
{
$system=explode(".",$name);
if (preg_match("/jpg|jpeg/",$system[1])){$src_img=imagecreatefromjpeg($name);}
if (preg_match("/png/",$system[1])){$src_img=imagecreatefrompng($name);}
$old_x=imageSX($src_img);
$old_y=imageSY($src_img);
if ($old_x > $old_y) 
{
$thumb_w=$new_w;
$thumb_h=$old_y*($new_h/$old_x);
}
if ($old_x < $old_y) 
{
$thumb_w=$old_x*($new_w/$old_y);
$thumb_h=$new_h;
}
if ($old_x == $old_y) 
{
$thumb_w=$new_w;
$thumb_h=$new_h;
}
$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y); 
if (preg_match("/png/",$system[1]))
{
imagepng($dst_img,$filename); 
} else {
imagejpeg($dst_img,$filename); 
}
imagedestroy($dst_img); 
imagedestroy($src_img); 
}

Thank you.

I forgot to put the function in the script .

Because you helped me, if you need the full script for this DEMO(login: demo and demo), you can take it from here.
