Sometimes, some of you may want to have a form redirect differently depending on the values the user has selected in it. You can apply a special message and destination url when a particular form field has a particular value, by adding the logic to your tweaks file like this:

$redirectchecks[0] = array("profile.php?action=editprofile", "fieldname", "fieldvalue", "redirect message to display", "destination url");
$redirectchecks[1] = array("profile.php?action=editprofile", "anotherfieldname", "anotherfieldvalue", "another redirect message to display", "anotherdestination url");
$redirectchecks[2] = array("suggest.php?action=addlink", "fieldname", "fieldvalue", "redirect message to display", "destination url");

Suppose you have a custom field in your 'submit article' form called 'iwantpageb'. When it has the value 'yes' you want to send people to b.html with a "thank you for choosing page b" redirect page message in the meantime. This is what you'd use:

$redirectchecks[0] = array("suggest.php?action=addlink", "iwantpageb", "yes", "thank you for choosing page b", "b.html");

If you want to test for something other than equality, you can specify another operator in an optional 6th term. This can be any standard PHP operator: >, >=, <, <=, !=. For example, to redirect when something is greater than 5:

$redirectchecks[0] = array("suggest.php?action=addlink", "something", "5", "thank you for choosing page b", "b.html", ">");
