[PHP] How do I stop foreach if $menu not set??
I Have worked out this, but when $menu is not set it does the foreach
function anyway, and desplays an error.
What Can I do to stop the foreach function from working if $menu is not
set??
?
if ($menu==(introduction)) {$sub = array(
'overview.php' = 'Overview',
'moreinfo.php' = 'More Info'
);
}
#These parts are topics and there may be more than two.
if ($menu==(support)) {$sub = array(
'sitemap.php' = 'Site Map',
'contact.php' = 'Contact Us'
);
}
foreach ($sub as $link = $name) (
$sublink .= lia href='.$link.'.$name./a/libr;
?
a href=?menu=introductionIntroduction/abr
? $introduction; ?br
a href=?menu=supportSupport/abr
? $support; ?

Change introduction to a variable with $ in front of it or put it in quotes
introduction.

'overview.php' = 'Overview',

Re: [PHP] How do I stop foreach if $menu not set??
You should be able to contain your foreach statement within an if statement:
if (isset($menu))
{
foreach ($sub as $link = $name) (
$sublink .= lia href='.$link.'.$name./a/libr;
}
else
{
print menu variable not set
}
Hope this helps.
