problem with variables working cooperatively... extreme newbie

10
below i have code from a simple php form program. you are supposed to enter your name in a text box and push the submit button. it then is supposed to bring you to a page that says "hello --your name here-- "
but instead it says "Hello $userName!; ?>" i tried rewriting it, ive tried fixing it different ways, and i thought maybe it had something to do with "register_globals" but i have a severe lack of understanding of it. however i do have it turned on (as i remember). anyways, here is the code of the original page first and after i will have the code of the second page. thanks

You're using shorttags (<? /*code*/ ?>) try using full tags (<?php /*code*/?>)

That book seems abit out-dated.

The code would work, had register_globals been enabled.

the full tags didnt do the trick. im running out of ideas. i think maybe there might be something wrong with my .ini file? or something i did wrong in the setup maybe? i even did a cross browser check and its all the same.

Try the above. The changes I make are as follows:

1) use of <?php instead of <? as PHP tag.
2) echo instead of print. Maybe print works fine, I just never used it :)
3) I broke up the argument to the echo statement to three pieces using the string concatenation symbol which is a period. I did this because you have a ! just after the PHP variable name. This is probably no problem, but I do this just to make sure the line is handled correctly by PHP. There are many ways of writing this line, but what I did above should work.
4) You need to retrieve the value of userName from the $_POST array. Note that the $_POST array may be case sensitive. I use Linux, which definitely is case sensitive, so in this case "userName" would be present but "username" would not be! I am not sure about PHP on Windows, whether that is case sensitive, but it is best to keep case sensitivity in case you ever need to port your scripts.

If the above does not work, then you need to examine your $_POST array and see if it is present and correct. To do this, try putting this statement in the script above, after the <body> tag:

echo "<pre>";
print_r($_POST);
echo "</pre>";

That should print a listing of your $_POST array. If it is empty or you do not see the entry for 'userName', then you need to inspect your php configuration to see why. Also make sure that the page that calls this script (the one the user submits) is properly set up such that the submit button and the userName input field are contained within the same form tags (if you put two sets of form tags on your page or made some mistake here, you may not get the input values to your $_POST correctly.
