$info_box_contents[] = array('align' => 'left', 'text' => '<a class="headerNavigation" href="' . tep_href_link(FILENAME_SPECIALS) . '">' . TABLE_HEADING_SPECIALS_MODULE . '</a>');
new contentBoxHeading($info_box_contents);

Many thanks in advance

In broad lines, you have to modify the code to

1) first run the "new" query

2) check the resulting number of rows

3) only if nbr of rows > 0 , execute all the rest

Many thanks for your help

I understand what you are saying in a consept, but my php knowlage is very poor, and my spelling. I am not able to write up the language.

If you could have a go at modifying the script, it would be greatly in dept to you

 

Kind Regards

 

Dave

Thanks!!!

You're the man!!

How would i go about learning PHP, I've picked up a little by looking at the scripts of OSC and the contributions, but it nothing compared to rewriting the script like that.

 

I would love to be able to modify it a little so it picks random specials from the database.

That would just add the finishing touches off to an exelent script

I think i am going to have to start compiling a contribution.

 

Many Thanks

 

Dave
