evanesq Posted May 23, 2008 Share Posted May 23, 2008 I am designing a website with several pages that are sequentially numbered, i.e., 0001.html, 0002.html, etc. I'd like to be able to put a <right arrow> button on each page, which when clicked, will send the user to the next sequential page. Is there a way to use a variable in the link, i.e., http://www.myweb.com/000n.html, and define the click on the button to make n=n+1? In other words, if someone is looking at 0001.html and clicks the <right arrow>, 0002.html should load. At the risk of being too annoying, I'd also like some sort of onerr command so that if the value of n exceeds the maximum number of pages and returns a 404, the user will be sent back to the main menu. I'm told this should be done in php, but I haven't a clue where to start. I'd appreciate any help.

smc Posted May 23, 2008 Share Posted May 23, 2008 <?php $myDomain = "http://www.myweb.com/"; //This is your base domain $currentPage = "0001"; //This is the current page. You can substitute this with a $_SERVER variable to get the current page $newPage = $currentPage++; //This adds 1 to the current page value $linkAddress = $myDomain . $newPage . ".html"; //This will put it all together, the myDomain, tacks on the current page +1 the finishes it up with .html ?> Link to comment https://forums.phpfreaks.com/topic/106880-using-variables-in-links/#findComment-547898 Share on other sites More sharing options...
