Guest edwinsweep Posted March 1, 2006 Share Posted March 1, 2006 hi everybodyi have been messing with my php script trying to get it to work.before trowing my monitor out of the window i thought maybe you guys know what is going on:)its a small piece of script from a forum.this peace of code delete's a complete topic from my forum and will also set the total number of replys back.lets say my counter is on 15 for the amount of replys that are on my forum.then when i delete a topic with only 5 replys in it, i want the counter to go back to 10.so i wrote this script.$quik =mysql_query("SELECT * FROM forumnews WHERE vantopicid = '$topic_id' ") or die(mysql_error());$ab =mysql_num_rows($quik);if (($ab = 1) OR ($ab = 0)){}else{mysql_query("UPDATE forums SET nrofreplys = nrofreplys-'$ab' WHERE forum_id = '$vfi' ") or die(mysql_error());}the damn thing just wont work, anybody have an idea???thanks in advance Quote Link to comment Share on other sites More sharing options...
AV1611 Posted March 1, 2006 Share Posted March 1, 2006 Is this closer to what you want?[code]$quik =mysql_query("SELECT * FROM forumnews WHERE vantopicid = '$topic_id' ") or die(mysql_error());$ab =mysql_num_rows($quik);if (($ab! <= 1){ mysql_query("UPDATE forums SET nrofreplys = nrofreplys-$ab WHERE forum_id = '$vfi' ") or die(mysql_error());}[/code] Quote Link to comment Share on other sites More sharing options...

AV1611 Posted March 2, 2006 Share Posted March 2, 2006 I've been bit by that a hundred times... I think it happens because you write an SQL query that does a single = followed by a PHP clause that uses a double ==That's my theory, anyways...I also cleaned up your first clause, by making the if !== you don't need the if then else you had before...
