ari_aaron Posted March 17, 2006 Author Share Posted March 17, 2006 Thank you, I want to have the page run an SQL query and then change a variable. Does refreshing a page clear the POST data that it received? if so, I would not want to do that (although I guess I could pass it on). I would want the new variable to be displayed, though.

I would want the new variable to be displayed, though.[/quote]$_POST variables are only received when a page is loaded, so i'm not sure what you mean by "clear" the data. if you're looking to have recurrent pages reference the same variable, you'll want to go with session variables, but let's take this one step at a time. copy and paste this code and see if it gives the basic idea of what you're after:[code]<?php$var = isset($_GET['var']) ? $_GET['var'] : 'none';echo "Value of \$var: <b>$var</b><br />\n";echo "<a href='?var=blue'>change to \"blue\"</a>\n";?>[/code]that should start out with the output:[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]Value of $var: [b]none[/b][/quote]then, when you click on the link, it should refresh as:[!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--]Value of $var: [b]blue[/b][/quote]if you understand the principles, you can easily apply a SQL query where you'd like instead of simply assigning the value to the variable manually.hope this helps!

ari_aaron Posted March 17, 2006 Author Share Posted March 17, 2006 yes, that is what I need, but when it loades the second time, it does not keep the POST data it received from before. How can I pass this on? Quote Link to comment Share on other sites More sharing options...
Spixxx Posted March 18, 2006 Share Posted March 18, 2006 The answer if you need to have a hidden input. Example: You have a form, a user submits the data, and is sent to another form within the same php code. You want to use the data from a previous field, or maybe even 2 or 3 forms back. Use this: [code]<input type="hidden" name="something" value="$something">[/code]Put that in a form to use that data in the next form, and even if you use it then, you need to use that everytime for the following page/form.I probably made it more complicated that it really is...but you'll get the idea.
