copied!<p>If you just want site.php to reload every 5 seconds and add 1 to whatever is the url for 'version' you could just use the following javascript (this is assuming that the user's edits are saved in sync) :</p> <pre><code>function getVar(name){ name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]"); var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var results = regex.exec( window.location.href ); if( results == null ){ return ""; }else { return results[1]; } } var version = getVar('vesion'); version = Number(version) + 1; window.setTimeout('window.location="http://test.com/site.php?version=' + version +'";' ,5000); </code></pre> <p>You may want to check that the version exists every 5 seconds instead. You would need to query the database from site.php for the current database version number and use:</p> <pre><code><?php //query your database ?> window.setTimeout('window.location="http://test.com/site.php?version=<?php echo $row['db_version_number']; ?>";' ,5000); </code></pre> <p>this will reload the database and refresh the page with whatever version is in db_version_number data cell every 5 seconds</p> ### Edited to answer second question <p>to start at 10 an stop at 20: initial url for the window would be site.php?version=10</p> <p>then:</p> <pre><code>function getVar(name){ name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]"); var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var results = regex.exec( window.location.href ); if( results == null ){ return ""; }else { return results[1]; } } var version = getVar('vesion'); version = Number(version) + 1; if (version < 20){ window.setTimeout('window.location="http://test.com/site.php?version=' + version +'";' ,5000); } </code></pre> <p>should do the trick</p>

Querying!
