I want to set a page number of a page
if(!isset($_REQUEST['page'])) {
$page =$_REQUEST['page'] + 1;
echo "page is ".$page; // this echos out page is 1
}
The problem is when I try and use $page further down in the body $page is 0
Question <?=$page; ?> <BR />
<? echo "page is".$page; ?>
<?=$question[($page-1)]; ?>
I also get an undefined index notice
Notice: Undefined index: page in
c:\Inetpub\wwwroot\lss\module_one\evaluation.php on line 8
page is 1
but I though if I do a if(!isset($_REQUEST['page'])) this is the way to set
a previously undefined index?
you have to check if page exists in $_REQUEST
if (!array_key_exists($_REQUEST,"page"))
{ $page = 1;
}
why do you wish to add something that's not set to a constant value ?
$page =$_REQUEST['page'] + 1;
