This actually requires two trips to the database, once to get $money and
once to update $money. Do it in the query instead...once.....
$sqlUpdate = "UPDATE `myDatabase`.`myTable` SET `myMoney` =
(`myMoney`-10) WHERE `myCharacter` = `characterName` ";
$doUpdate = mysql_query($sqlUpdate, $myConnection);
saves lots of characters ;)
Hey, Look I made a new database just for this money testing stuff.
This is the table:
CREATE TABLE `money` (
`money` varchar(255) NOT NULL default ''
) TYPE=MyISAM;
Now, I use this code
$sqlUpdate = "UPDATE `myDatabase`.`myTable` SET `myMoney` =
(`myMoney`-10) WHERE `myCharacter` = `characterName` ";
$doUpdate = mysql_query($sqlUpdate, $myConnection);
And it should work, And it gives no error but it is not writing
anything into the database.
Lots of extra characters in that one... try this:
$q=mysql_query("update myTable set myMoney=(myMoney-10) where
myCharacter='characterName'");
if(!$q){echo mysql_error();}
so wasteful :-)
$q=mysql_query("update u set m=(m-10) where c='$c'");if(!$q)die(mysql_error());
