you need to check the num of rows returned, since the query always(if it
works) returns true
$result = mysql_query($query);
if (($result)&&(mysql_num_rows($result)==1))
{
echo "Alias already in use";
} else {
echo "Unique alias";
mysql_close();
}

Subject: If syntax

Take a look at my if ( ) syntax line below. I am wondering if I have it
wrong in same way. What I am trying to achieve is if the alias the user
enters is already found in the database I want the words "Alias already in
use" to be shown on the screen; otherwise "Unique alias" to be shown on the
screen.
PRESENTLY alias already in use is what comes up all the time.

mysql_connect(localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT * FROM tablename WHERE alias LIKE '$alias%'";
if (mysql_query($query))
{
echo "Alias already in use";
} else {
echo "Unique alias";
mysql_close();
}
