The form itself, yes, can only have one or the other method attribute. What it sounded like was: What others have not addressed is that the form used to send variables will send only GET OR POST method variables, but not both at the same time. I still stand by that statement. A form can only send variables through the method stated in the form. The "action" value of the form is not data provided by a POST-method form -- it simply uses the address provided by the coder. If you want to add GET data to the action value, then that's your call, but the POST method form will do nothing to the action value data. However, a GET-method form will change the action value. Try this as an experiment. Use a GET form with the action value containing get type data (?id=1234) and see what happens to that data. If you do, then you'll have a better idea of what you can/can't do with a form.

A form can only send data it has collected via it's declared method and the choices are POST or GET, but not both. Please review the post I made to Paul on this subject -- that explains this concept better.

So what am I missing? Is there an error in my code? Paul -- Paul M. Foster http://noferblatz.com Paul: What I am saying is your form is a POST-method-form and it will only send variables via the POST method. If you change the form's method to GET, then the variables from the form will be sent via the GET method. Remember, there is ONLY ONE form being used per Submit action -- it can either be a POST method or a GET method, but it can not be both. This does not mean that you can't send both POST and GET variables together via the same Submit action, but it does mean that the *form* will only send it's contents via one method or the other. Here's a demo: http://php1.net/c/post-get Please note that the POST method form will send only POST data and the GET method form will send only GET data. However, you can force a POST method *form* via the action attribute value to also include a GET variable (see Submit POST w/GET) -- BUT -- that does not come from the form's input but rather from the action attribute. Do you see what I mean? The code is shown. Also, please note interaction between the GET/POST/REQUEST re the variable 'alfa' and you will get an idea of why REQUEST may pose a problem.

So, I don't think one can write a small simple script that > can demonstrate this. I'm sure I must be misunderstanding something here. The following is a script which will show both GET and POST being received by the script, and with the same variable names but different values: =-=-=-=-=-=-=-=-=- \n"; print_r($_GET); print "\n"; print "POST:\n"; print_r($_POST); ?> =-=-=-=-=-=-=-=-=-= Call this script via test.php?alfa=1234 Call it the first time this way and leave that in the location bar of your browser. Now fill in the value in the blank with the value 4567. Press the "submit" button. You will see that $_POST['alfa'] returns 4567, while $_GET['alfa'] returns 1234. It sounds like you're saying this isn't possible, yet it is. So what am I missing? Is there an error in my code? Paul -- Paul M.
