echo "

<input type=\"text\" id=\"inputnumber\" value=\"\" /> 
<input type=\"button\" value=\"Go\" onclick=\"javascript:window.location='". $_SERVER['PHP_SELF'] . "?pagenum=document.getElementById('pagenumberinput').value;\" />"; 
 

When i click on Go button nothing happens.
For example in the input field i typed 2. When i press Go i should go to page localhost/facts/pagination2.php?pagenum=2 but it doesnt happen like that. when i press go nothing happens.
I looked at the output source code. it looks like that :

<input id="pagenumberinput" type="text" /><input type="button" value="Go" onclick="javascript:window.location='/facts/pagination2.php?pagenum=document.getElementById('pagenumberinput').value;" />

Any ideas how to correct this?

why not just use php?? Submit the form to a processing page and siply redirect to the page number, it will be accessible as well. No need for javascript in the situation.
