php/mysql account activation

Question

Everything in my new website is working just fine, except that I can\'t get this piece of code to work:

$query = mysql_query(\"SELECT * FROM members WHERE userem         


        

Answer 1

Change your first line to:

$query = mysql_query("SELECT * FROM members WHERE useremail = '$useremail'") or die(mysql_error());

And it will spit out the mysql error that is causing the Warning =)

You should not be presuming the call to mysql_query returns a valid result; It's good practice to always test the result first, e.g.

$r=mysql_query("SELECT * YADYADA");
if($r && mysql_num_rows($r)>0){
  $row=mysql_fetch_assoc($r);
}else{
  //Uh oh, something's not right~~~ throw an exception maybe?
}
