How to define a function

Karlin

Hi,

I am fairly new to PHP. I have downloaded the osCommerce shopping cart. Awesome shopping cart, by the way!

Anyways, I installed a module that automatically resizes pictures of my products. It all works well unless I try to modify the product, or add a new one in the Admin panel. I receive the following error message in my browser:

Fatal error: Call to undefined function: set_resize() in .../scripts/OS_Commerce_Shopping_script/catalog/admin/categories.php on line 321

Here is a snippet of the categories.php file around line 321:

314 // copy image only if modified
315 // $products_image = new upload('products_image');
316 // $products_image->set_destination(DIR_FS_CATALOG_IMAGES);
317 // if ($products_image->parse() && $products_image->save()) {
318 // copy image only if modified

319 $products_image = new upload('products_image');
320 $products_image->set_destination(DIR_FS_CATALOG_IMAGES);
321 $products_image->set_resize(true);
322 if ($products_image->parse() && $products_image->save()) {
323
324 $products_image_name = $products_image->filename;
325 } else {

326 $products_image_name = (isset($HTTP_POST_VARS['products_previo
us_image']) ? $HTTP_POST_VARS['products_previous_image'] : '');

327 }
328 break;

I am fairly ignorant about coding, so I have no idea where to look to see if the function is defined improperly, or even if it is defined at all. Any help would be greatly appreciated!

Well, here's where it's calling it.

$products_image->set_resize(true);

You need to find the actual function though. Should be on this page, or through an include or require call

include("somepage.php");
require("someOtherpage.php");

The start of it should look like this...

function set_resize($var) {
    //$var is probably not what they used, but I dunno

That's the problem with using someone else's script. You should know the code of things you're using. Good luck.

OK, I did this:

egrep -r "function set_resize" *

and found it in /includes/classes/upload.php. Here is what it looks like:

297     function set_permissions($permissions) {   
298       $this->permissions = octdec($permissions);
299     }
300                 
301     function set_resize($resize) {
302       $this->resize = $resize;
303     }
304
305     function set_debug($debug) {
306       $this->debug = $debug;

Now that I have found the actual function, what do I do next?

Is upload.php included on the file that you're getting the error from

Karlin

No, but I did add this line in the /admin/categories.php file:

Released under the GNU General Public License
11 */
12

13 require('includes/application_top.php');
14 require('includes/classes/upload.php');
15 require(DIR_WS_CLASSES . 'currencies.php');
16

17 $currencies = new currencies();
18

19 $action = (isset($HTTP_GET_VARS['action']) ? $HTTP_GET_VARS['action']

I don't know if I used the correct words, but I tried to follow the convention used for the previous line.

This did result in a new error in the browser:
Fatal error: Cannot redeclare class upload in /var/www/karlin/public_html/scripts/OS_Commerce_Shopping_script/catalog/admin/includes/classes/upload.php on line 13

Here is a snippet of the upload.php file that the error points to:

 11 */
 12
 13   class upload {
 14     var $file, $filename, $destination, $permissions, $extensions, $tmp_

filename, $message_location;
15
16 function upload($file = '', $destination = '', $permissions = '777',
$extensions = '') {
17 $this->set_file($file);
18 $this->set_destination($destination);
19 $this->set_permissions($permissions);
20 $this->set_extensions($extensions);

Can anyone help me at this point? I am completely unsure what to do to resolve this problem. I have removed the line:

require('includes/classes/upload.php');

from the /admin/categories.php file, so I am back to the original problem. Any help would be greatly appreciated .
