untouchable genearl.php

Recommended Posts

I am using osC BS Edge version to install the file. Has this Add-On Compatibility for 2.3.4 EDGE
Add some addons and did not notice admin/catagories has missing the SAVE button till yesterday. Found out that the file making the problem is admin/includes/functions/general.php

need to modify the file for KISSIT image thumbnail.

this is the original file that can show up the SAVE button (but when open in the dreamweaver, you can notice the colour is different as missing ?> and have unnecessary space, BUT it show up the button.

admin/includes/functions/general.php

    while ($customers = tep_db_fetch_array($customers_query)) {
       $select_string .= '<option value="' . $customers['customers_id'] . '">' . $customers['customers_lastname'] . ', ' . $customers['customers_firstname'] . '</option>';
    }
	    $select_string .= '</select>';
    return $select_string;
  }
 

however, you can not touch any thing, not even delete a space nor put ?> , of course nor any other extra code. Otherwise it will make the 500 Internal Error, and the admin page goes completely blank.

Can any one please help to fix the problem?

The not working solution I had tried is to go to oscommerce.com to download 2.3.4 version, and replace 2.3.4 general.php file, even though it will not cause the blank (500 Internal Error), the SAVE button could not show up.

 

No idea what is going on...please help. Thanks!

Well, complains are good. It helps you narrow down the problem. Check you file permission and etc. for 500 IE. The web server is complaining. If you have code error, then the PHP parser will complain. U may wanna hire someone to help you with this.

If the file is exactly as posted, then the problem is probably with the <?php. Try moving it so it starts in column 1. If that is not it, you may want to use a php editor instead. It has been a long time since I used DW but when I did, there were problems with it and php code. But maybe that is no longer the case. It also might matter which php version you are using since your file is not the latest one and will throw warnings or errors, depending upon the version.

It is never wise to mix files from different versions of osCommerce.

You said that you are using osC Edge, and have the compatibility add-on installed. You are now trying to install KISSit Image Thumbnail when you discovered this problem. Is this all running on an in-house server, or on your host's server? What version of PHP is being used?

Dreamweaver is NOT a good tool to use when editing osCommerce files. Many people recommend Notepad++ (which I use, although I also use plain old Notepad most of the time). Notepad++ also uses colors to highlight areas and/or missing bits.

If your files are on your host's server, some FTP clients (such as Filezilla) allow you to edit the file directly on the server (well, it makes a copy on your workstation, you edit it there, and then it uploads it back to the server). The other way is to have a complete copy of all your files on your local workstation, edit them locally, then upload any edited files back to the server.

As @Jack_mcs pointed out, there are some blank spaces before the opening <?php in the code you posted. This can cause the PHP engine to crash. Remove those blank spaces, so that <?php begins in the first column.

Hi Malcolm & Jack_mcs,

Thank you for the reply.
It is true not wise to mix the version. So I start over again with the new 234.1 version.
Once again, thanks!
