MySQL - if ???

Hi.
I have used this clause(?):
<code>
$query = "SELECT * from $table WHERE name='$name'";
mysql_query($query);
// check to see if there are any entries under that name
</code>
now I am using an 'if' statment, however I do not know the right thing to write.
<code>
if (I_NEED_TO_PUT-RECIEVED_RESULST_OR_SOMTHING != 0) {
echo "Name already chosen - please try again.";
}

else {
$query = "INSERT INTO...
</code>
e.t.c.
I am not sure what to put in the 'if' statement.
Please help
Thanks!

RE: MySQL - if ???

Use this:

php Code:

Original - php Code
$query = "SELECT * from $table WHERE name='$name'"; $result = mysql_query($query); $num_rows = mysql_num_rows($result); if ($num_rows > 0) { echo "Name already chosen."; } else { your insert query }

 
$query = "SELECT * from $table WHERE name='$name'";
$result = mysql_query($query);
$num_rows = mysql_num_rows($result);
if ($num_rows > 0) { echo "Name already chosen."; }
   else { your insert query }
