The "More Pots" pages use a basic template page with just the banner and navigation bar elements. The area where text normally is written was expanded downward. Using a right-click on that area I inserted the following HTML in the "HTML inside" area:
<SCRIPT> var url=document.URL; var pos=url.indexOf("?"); var newurl="/pots.php"; if(pos>0) {newurl="/pots.php"+url.substr(pos);}; document.write('<iframe height="100%" name="Aframe" width="100%" id="Aframe" src='+newurl+'> </iframe>'); </SCRIPT>
This code looks for optional parameters passed in the URL, for example,
http://coffeepottery.com/blank.html?p=5
includes the optional parameter: ?p=5
If there are optional parameters the code appends them to "/pots.php". The resulting URL is used as the source for an iframe that occupies the entire text area.
The pots.php script then uses the parameters to select the data to be shown.
