Trying to do IF ($smth= BALNK) else...

Anon

hi,

i am trying to figure out if this is possible.

i want to include an image on a page that has a list of ads, but not on the page when you view the details of the ad.

the main page has a var of ID and the details of the ad have vars of ID and AD. my thinking is that if $ad is blank, i want to include the image, but if it is posted, then the image doesnt display. the page that displays the details is the same page that displays the list of ads.

here is what i am trying now, but am only ablr to get the image to display on all the id supplied pages.

if ($ad <= "0")

if ($id == "17"){
	print "<center><img src=\"http://mysite.gif\"></center><br>\n";
} elseif ($id == "18"){
	print "<center><img src=\"http://mysite.gif\"></center><br>\n";
} elseif ($id == "19"){
	print "<center><img src=\"http://mysite.gif\"></center><br>\n";
} elseif ($id == "20"){
	print "<center><img src=\"http://mysite.gif\"></center><br>\n";
}  elseif ($id == "1"){
	print "<center><img src=\"http://mysite.gif\"></center><br>\n";
}

else

echo ".";

also, if there is a way to just include all the $id var in the same statement that would be great.

thanks

If I understand what you want correctly, then this should work:

if(!isset($ad)) {
print "<center><img src=\"http://mysite.gif\"></center><br>\n";

}

thanks, but it doesnt seem to work the way i am looknig for. below are the two links. the first one displays the page with all the ad titles within category 44.

the second displays the details of a certain ad with in that category.

http://www.mysite.com/showads.php?id=44

http://www.mysite.com/showads.php?id=44&ad=2070

i would like to have an image display only on the page WITHOUT the passed ad variable, so....essentially, i am thinking that if there is no ad number passed in the url, then the IF statement should execute.

currently, your suggestion fails the IF and goes right to the ELSE for all the pages.

hope fully this is a bit more clear.
thank you for your time and guidence.
