wildteen88 Posted January 9, 2010 Share Posted January 9, 2010 Are they any errors? _POST variables are treated the same as any other variable. Link to comment https://forums.phpfreaks.com/topic/187855-_post-variable-un-useable/#findComment-991845 Share on other sites More sharing options...

jl5501 Posted January 10, 2010 Share Posted January 10, 2010 It looks to me like a problem in your quoting try something like this $currsel1 = mysql_query("select id from page0.page0 where refnum =\'".$oldnum."\' AND username!='admin'") Link to comment https://forums.phpfreaks.com/topic/187855-_post-variable-un-useable/#findComment-992284 Share on other sites More sharing options...
mattal999 Posted January 10, 2010 Share Posted January 10, 2010 It looks to me like a problem in your quoting try something like this $currsel1 = mysql_query("select id from page0.page0 where refnum =\'".$oldnum."\' AND username!='admin'") Actually that won't work. That would output: select id from page0.page0 where refnum=\'123\' AND username!='admin' It should be: $currsel1 = mysql_query("SELECT id FROM page0.page0 WHERE refnum='".$oldnum."' AND username!='admin'"); Link to comment https://forums.phpfreaks.com/topic/187855-_post-variable-un-useable/#findComment-992285 Share on other sites More sharing options...
