I see your question has already been answered, but I'll add a tip that works well for me. Whenever I want to perform an SQL query that involves PHP variables I will write the query string to its own variable instead of directly into the function. Then use that variable in the query function...
$query = "SELECT * FROM my_table WHERE column1 = '$mydata' && column2 = '$mydata2' ORDER BY $order_col $asc_desc"; $result = mysql_query("$query", $db); -Kevin ----- Original Message ----- From: "Gerard Samuel" <[EMAIL PROTECTED]> To: "PHP" <[EMAIL PROTECTED]> Sent: Wednesday, December 12, 2001 7:08 AM Subject: [PHP] Single/Double Quotes > Im tring to rewrite some code to use single/double quotes correctly (as > correct as can be). > > If I use > $result=mysql_query('SELECT book FROM ' .
