Undefined variable in imagecreatefromjpeg()

[bugzy]

I was researching on how will I able to resize an image on image retrieve and I got this function

 

<?php

function me_resize_jpeg( $original_image, $new_height, $new_width, $filename )
{  
   // Resize the original image
   $image_resized = imagecreatetruecolor($new_width, $new_height);
   $image_tmp = imagecreatefromjpeg ($original_image);
   imagecopyresampled($image_resized, $image_tmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
   
   imagejpeg($image_resized, $filename.".jpg", 100);
   imagedestroy($image_resized);


}


?>

 

and I'm using it this way

 

<?php

$target_path = "../images_item/";

me_resize_jpeg($target_path.$edit_id.".jpg",'100','50',$target_path.$edit_id);

?>

 

 

 

But I'm getting this error:

 

Undefined variable: width in C:\wamp\www\runa\includes\functions.php on line 58

 

Undefined variable: height in C:\wamp\www\runa\includes\functions.php on line 58

 

 

The function is only asking for four parameters and I don't if the function is missing something...

 

Anyone?

You got a bad function. Find one that works

As the error messages tell you, $width and $height have no values. They should contain the width and height of the original image.

 

Put

$width = imagesx($image_tmp);
$height = imagesy($image_tmp);

 

before calling imagecopyresampled()

@Barand got to it before I could. From the php page, there are a few examples of how to get the variables of the original image. One example is:

 

list($width, $height) = getimagesize($original_image);

Just a side question guys...

 

Does imagecreatefromjpeg()  actually resize the original image on the server side, or it's being resize only on the end-user?

@bugzy, go to my web server and see how does my script work is.

I've used jQuery Image Cropping Plugin and php scripts to resize images.

If you like it I'll give you the scripts.

imagecreatefromjpeg() doesn't do any resizing - it just converts a jpeg image to a GD image.

From the word converting, so the original image will be a GD file now literally? and imagecreatefromjpeg() doesn't do any and image duplication? like the duplicate one will going to be the GD file? and the original will still be there as is? 

 

Just want to be sure guys..
