[SOLVED] Thumbnail from image upload

rwt · June 21, 2007

Hello.

I created an upload form with then creates a thumbnail.

The I got to a point were everything seemed to work fine exept that is was only for JPEG image types.

So I tried adding in the thumbnail function an if statement to detect what filetype it was. But then the jpeg don't show anything and gif/png get an error message!

<html> 

<head> 
<title>Upload</title> 
</head> 

<body> 
<?php 
if(!isset($_POST['Upload'])) 
{ 
include("upload_form.inc"); 
exit(); 
}/*endif*/ 
else 
{ 
if($_FILES['pix']['tmp_name'] == "none") 
{ 
echo "<b>File did not successfully upload. Check the file size. File must be less than 1Mb.<br>"; 
include("upload_form.inc"); 
exit(); 
} 
if(!ereg("image",$_FILES['pix']['type'])) 
{ 
echo "<b>File is not a picture. Please try another file.</b><br>"; 
include("upload_form.inc"); 
exit(); 
} 
else 
{ 
function thumbnail($image_path,$thumb_path,$image_name,$thumb_width) 
{ 
    if(ereg("image/pjpeg",$_FILES['pix']['type'])) 
    { 
    $src_img = imagecreatefromjpeg("$image_name"); 
    } 
    elseif(ereg("image/gif",$_FILES['pix']['type'])) 
    { 
    $src_img = imagecreatefromgif("$image_name"); 
    } 
    elseif(ereg("image/png",$_FILES['pix']['type'])) 
    { 
    $src_img = imagecreatefrompng("$image_name"); 
    } 
    else 
    { 
    $src_img = imagecreatefromjpeg("$image_name"); 
    } 
    $origw=imagesx($src_img); 
    $origh=imagesy($src_img); 
    $new_w = $thumb_width; 
    $diff=$origw/$new_w; 
    $ratio=$thumb_width/$origw; 
    $new_h=$origh * $ratio; 
    $dst_img = imagecreatetruecolor($new_w,$new_h); 
    imagecopyresized($dst_img,$src_img,0,0,0,0,$new_w,$new_h,imagesx($src_img),imagesy($src_img)); 

    imagejpeg($dst_img, "$thumb_path/$image_name"); 
    return true; 
    } 
} 
$ran = rand (1, 100000) ; 
$destination = $firstname."".$ran.".".$_FILES['pix']['name']; 
$temp_file = $_FILES['pix']['tmp_name']; 
move_uploaded_file($temp_file,$destination); 
$imgpath = "http://www.mywebsite.ch/rwt/junk/UPLOAD%20AND%20SEND/{$ran}.{$_FILES['pix']['name']}"; 
echo "<p><b>Your image:</b></p>"; 
thumbnail(0,"thumbs","{$ran}.{$_FILES['pix']['name']}",200); 
echo "<a href='$imgpath' title='$firstname portrait' target='_blank' alt='$firstname portrait><img src='http://www.mywebsite.ch/rwt/junk/UPLOAD%20AND%20SEND/thumbs/{$ran}.{$_FILES['pix']['name']}' style='border: 1px solid #C0C0C0' alt='$firstname'></a>"; 
} 
?> 

</body> 

</html>
