skycruiser Posted February 16, 2007 Share Posted February 16, 2007 I'm a php/mysql noob and I'm a little stuck at the moment. I've got one page that generates a set of POST variables (number depends on the number of records in a mysql query). The vars are doc_master0, doc_master1 etc. That part works fine. I can see that the variables are available on the next page. I can echo them directly. But I'm trying to access those variables in a loop and there's where I'm running into trouble. In my loop with index 'i', I'm creating a temp variable $doc_master_temp = "doc_master".$i; But if I try to retrieve that post variable with $doc_master = $POST_["doc_master_temp"]; I get an error undefined POST variable. I also tried $doc_master = $POST_["$doc_master_temp"]; Is there any way to get this to work or do I need a completely different approach (arrays or something??). Thanks for the help!

Jessica Posted February 16, 2007 Share Posted February 16, 2007 It's $_POST not $POST_ Link to comment https://forums.phpfreaks.com/topic/38771-solved-help-passing-variable-num-of-post-variables/#findComment-186281 Share on other sites More sharing options...
skycruiser Posted February 16, 2007 Author Share Posted February 16, 2007 lol i'm an idiot. Stupid typos!!! Awesome works now (with the $var, not just var). Thanks for the quick reply. I've been banging my head all morning.

Jessica Posted February 16, 2007 Share Posted February 16, 2007 Also, don't put the variable in a string in the post if it's just the var. $_POST[$doc] not $_POST["$doc"] - it's extra work for PHP to do that way.

skycruiser Posted February 16, 2007 Author Share Posted February 16, 2007 Can't PM yet. wanted to say I'm also in Richardson TX - at UTD. And I noticed you do freelance work. Once my database is done and ready to go online we may want an "expert" review for security issues or other general advice. I'll keep you in mind when we get there (if you're interested).
