PHP PDO sql query and results -


i'm having issues implementing sql query using pdo. 

$friend_emails = $pdo->prepare("select distinct user2                     members                     user1 = '$user'                     union                     select distinct user1                     members                     user2 = '$user'"); $friend_emails->execute();  for($i=0; $row = $friend_emails->fetch(); $i++) {      echo "foo"; }

"foo" doesn't show @ all. var_dumped $row , $friend_emails->fetch() both of 

boolean false

so i'm not sure why is, thought return array of data.

any appreciated!

use while here

while($row = $friend_emails->fetch()) {     echo "foo"; }

your loop never execute because 

for($i=0; $row = $friend_emails->fetch(); $i++)           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ // here $i not present

the correct format be

for($i=0; $i <= count($friend_emails->fetch()); $i++)

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
