I stripped down my original script until it started receiving POST data, then I kept modifying it until I figured out where the problem was. I found it, but I'm still as clueless as every. To summarize: I have a form that posts to the same script that contains the form. In its original state, when the script is called after I submit the form data, the $_POST[] data is completely empty and the _SERVER variable that indicates the type of data is set to "GET". In the script is the following code: if (IsSet($_POST["action"])) {

//    $action = $_POST["action"];

} else {

    $action = $_GET["action"];

} Normally the second line is not commented. When I comment out that line, then the $_POST array has all of the data I would expect it to. When it is not commented, then it does not work. Just to make sure that I am really confused, this bit of code is *after* the call to var_dump($_POST), but *before* the code that creates the form. Does anyone have any ideas about why setting this variable has such a large and seemingly unrelated affect?

WILD GUESS: Somewhere in your form and/or the logic, you are sending GET data for $action as well as POST data for $action, and you are confusing the two. Show us your stripped-down but still-broken code.

Thanks for sticking with me. I tried stripping it down again, but then the stripped down version worked (even with the problem line). That means I need to take a couple more passes at it and figure out what else is working with this line that causes the problem. I did determine that it is not the name of the $action variable or the "action" POST value. If I manually set $action to "login", it causes the problem, but if I set it to "loginx", then the post values come through correctly. I didn't write this script, and I'm seeing the same problem in phpMyAdmin, so I don't think it is a coding problem unless it is an incompatibility between php4 and php5. I still need to track it down further. I'll let you know what I find.
