mysql_fetch_assoc() expects parameter 1 to be resource, boolean given HELP PLEASE

Hi
I am getting this error:
Warning: mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in /home/likethesethings/public_html/like.php on line 9

Here is the code I have at top of like.php:

<? include ("config.php");
$linkget1= trim(str_replace("-"," ",strtolower($_GET["like"])));
$linkget2= trim(str_replace("-","-",$linkget1));
$linkget3= trim(str_replace("","\\",$linkget2));
$linkget= trim(str_replace("-","\"",$linkget3));
$linkget= trim(str_replace("","?",$linkget));
$linkget= trim(str_replace("","/",$linkget));
$linkget= trim(str_replace("","@",$linkget));
$lingetk= trim(str_replace("",",",$linkget));
$linkget= trim(str_replace("-","---",$linkget));
$linkget= trim(str_replace("-","--",$linkget));
$x=mysql_query("SELECT * FROM fblike WHERE likee='".$linkget."'");
while ($y=mysql_fetch_assoc($x)){
$like=$y['likee'];
$new_hits=$y['hits']+1;
$hits=$y['hits'];
}
mysql_query("UPDATE fblike SET hits='$new_hits' WHERE like='$linkget'");
?>

It happens whenever type text in the URL as an 'id' for the page instead of a number id.
Please can someone help me fix this.
Thanks

 

you have to sanitise this:
x=mysql_query("SELECT * FROM fblike WHERE likee='".$linkget."'"); <-------

also, please double check you like keyword (you may want to use ` if that's the field):
mysql_query("UPDATE fblike SET hits='$new_hits' WHERE like='$linkget'");
