form variable instantiation problem

djkanebo

Hi all,

I have written some code in a simple program and tested to see if it is posting the variables through the form. However the variables are not being posted to the action page!

As i was certain my code was correct, I sent the code I wrote to a friend of mine who uploaded it onto his server where the files worked fine! Has anyone any idea why this may be?

Please help if u can!

Well, problem one: You didn't show us a lick of code, so we'll have to test our mind reading skills here.

The usual cause of this is because register_globals is on on one server and not on the other.

Heres the code

test.htm

<html>
<head><title>COCOMO Model</title></head>
<body bgcolor=cornsilk>
<center>
<form action=testprocess.php method="POST">
<table align=center>
<tr>
<td>Input 1</td>
<td><input type="text" name="input1"> </td>
</tr>
<tr>
<td "colspan=2"><input type="submit" name="submit"></td>
</tr>
</table>
</form>
</center>
</body>
</html>

testprocess.php

html>
<head><title>COCOMO Model</title></head>

<body bgcolor=cornsilk>
<center>
<h2>You have input... </h2>
<?php
$a = $HTTP_POST_VARS['input1'];
echo "$a";
?>
</center>
</body>
</html>

Please help once again!

Two things to try:

1) On your form, quote around the action also
<form action="testprocess.php" method="post">

2) Instead of using HTTP_POST_VARS, use $POST
$a = $POST['input1'];
read here on that.

if u use 4.1.0 or later, use $_POST as you would use $HTTP_POST_VARS. the difference is that its already global.

i have the tried all these things already lads! i dont have a clue what to do next!

gahbryel

ok then, try this out cuz i use it everyday. simply use your variable as if it were declared and instancied.

<?php
if(isset($input1)) echo "$input1";
?>

djkanebo

still no luck even with that!

gahbryel

i know this may look stupid but is your php server even started ??? if not, it would simply ignore the <?php ?> tag and all within, explaining why you don't have any result. if not, sorry but i'm out of solutions :p

LordShryku

at the very top of the second page, do this

<?php
print_r($_POST);
?>

That should tell you conclusivly if the are being passed or not.

If anyone is stupid it is me!

How do u start the PHP server?

I installed it following the instruction specified... It seemed to report all the correct messages when i installed it

how can i test this?

gahbryel

err, first thing first, try <?php echo "hello"; ?>

if it write hello, your server intreprets php ok, so the problem is elsewhere.

if not, it depends on your php server. if u'r using easyphp, be sure that it is started. in the taskbar, the icon shoul resemble to the letter "e" it a small red dot in the lower right. if it's not there, load the program. if the icon is there and the dot is blinking, the server is on. if not, right-click the icon and select start server or something of that sort.

if u'r not using easyphp, then if u have a network tech or administrator, i suggest getting in touch with him to confirm :p

i'm no expert, i only know the basics but this could help
