I have boiled the problem down to a simple example and still don't understand the stupid mistake I must be making.

Trying to send data back to another page which will use it via a $_GET['some_data'] variable.

The problem is, my form works but the "some_data" does not get appended to the URL, only the question mark. Here's the simple HTML...

Code:

<HTML>
<HEAD>
<TITLE>test send back</TITLE>
</HEAD>
<BODY>

The URL that gets sent when button is pushed should be "foo.php?some_data"<br>
but the "some_data" gets left off.

<form action="foo.php?some_data"> 
<INPUT TYPE="SUBMIT" VALUE="continue">
</form>

</body>
</html>

My "foo.php" script never sees that data I am trying to pass to it.

Use a hidden field:

PHP Code:


			
<html>

<head>

<title>test send back</title>

</head>

<body>



The URL that gets sent when button is pushed should be "foo.php?some_data"<br>

but the "some_data" gets left off.



<form action="foo.php" method="post"> 

<input type="hidden" value="value" name="some_data" />

<input type="submit" value="continue" />

</form>



</body>

</html>

The problem of using a form without the method defined is sent using the get method automatically by the browser, and using your code above as an example, the some_data get parameter is being overwritten by the form input values.

If you specifiy post as the form method, the form input data will not overwrite your get params in the form action url.

Thanks mgraphic,

I wanted to use GET method so I could observe the data sent to the target script via the URL. This worked:

Code:

<form name="input" action="foo.php" method="get">

<input type="hidden" name="something" value="this_thing" />
<input type="submit" value="do it" />

</form>

Things like this seem so simple once figured out.
