If You want to store information in a variable and than print it out, check if you use something like this:

Code: Select all: echo $html_variable;

or better use such structure:

Code: Select all: ... php code ... ?> ... html code ... <? ... php code ...

these were the only changes i made to the httpd.conf file

ScriptAlias /php/ "c:/php/"
AddType application/x-httpd-php .php
AddType application/x-httpd-php .php3
AddType application/x-httpd-php .php4
AddType application/x-httpd-php .htm
AddType application/x-httpd-php .html
AddType application/x-httpd-php .phtml
Action application/x-httpd-php "/php/php.exe"

when i execute phpinfo(); it works fine but i can't get to pass a variable from a html form to use it in any other place.

That's all what you change in httpd.conf?
How about cgi.force_redirect = 1?

I have checked this forum and I found that many people here have the same problem as mine, that I cannot retrieve the variable content to php script from html form. This is a simple sample I copy from my beginner's book, and it's just don't work in my LAMP:

<html>
<body>
<form action="thisfile.php" method="GET">
<p>Give your name: <input type="text" name="yourname">
<br><input type="submit" name="Submit">
</form>
<?php

print("$yourname\n");
?>
</body>
</html>

very simple isn't it? but the $yourname inside the php tags can just never get the value of the yourname that I type in the text box, it's empty.
I noticed that this seems work in php3 but not php4 right? So how is the correct way to do this? even my php4 begineer book is teaching the wrong thing

check php.ini
find this string:
register_globals = Off and change at register_globals = On
at your place i'm install PHP as ISAPI module not like CGI...

In php4 you can't use $yourname, you have to use : $_POST['yourname'];
because global vars are off

can you give a sample of code u use?

by **parxal** » Tue Nov 26, 2002 9:38 am

make a html file with:

<form name="form1" method="post" action="enviar.php">
<p>Name :
<input type="text" size=40 name="name">
</p>
<input type="submit" name="submit" value="Enter information">
</form>

This will create a form with a textbox named name

make a php file named enviar.php with :

<?
$name=$_POST['name'];
printf("the name is". $name);
?>

this will print the name that tou put in the textbox.

What's the point for php4 to turn the register_globals off? Security?
I m supposed to turn it on or use $_POST[] ?

by **parxal** » Tue Nov 26, 2002 12:35 pm

it's supose not turn it on, in http://www.php.net they advise to use new php4 methods!
