Variables Not working across pages HELP!

[seanmayhew]

I am working on localhost I've tried both URL queries and form submits but the variables will not move from one page to the next. My variables all work within their own document but never from one page to the next. Im using Apache and checked the httpd.conf file and everything else i think im supposed to but its just not working any help would be greatly apprecaited.

Hi buddy!

the only way to pass a variale from one page to another is by using the GET or POST methods:

by url adding:

page_to_go.php?variable_name=value
this may be absolute address or relative one.

by form:

<form action="page_to_go.php" method="POST/GET">
<input type="text" name="variable_name" value="initial value">
<input type="submit" value="Go!">
</form>

The only one you want to chose here is if you want to use the GET method(actualy the same as adding to the url as described above) or POST method. In the second way to access the variable try $HTTP_POST_VARS["Variable_name"]

Any questions are welcome.

Guess I should have explained better I know how to pass the variables and I have two sample pages that work fine on my testing server but I cant get them to work locally on my local set up of apache php and mysql

Have you been able to get any php outup at all on your local server?

filename = phpinfo.php

<?php

phpinfo();

?>

Yes PHP works when I'm working within a single page but when I try to use variables across pages I get no results.

Please be specific. Like, foo.php?a=b are you trying print $a or print $GET['a'] or print $HTTP_GET_VARS['a'] or print $REQUEST['a']... and what exact php version do you have? First guess, register_globals bites again.

[seanmayhew]

Im just trying to echo the output

http://localhost/test.html?name=sean

in the php file i enter

echo $name;

results in nothing

my version is 4.2.3 and for reference when you mentioned register globals i checked the phpinfo(); and it does say that register_globals is off for both.

[seanmayhew]

Im sorry that should have read

<a href="http://localhost/test.php?name=sean>The Link</a>

[philipolson]

Please read the manual entry on register_globals:

http://www.php.net/manual/en/configuration.directives.php#ini.register-globals

As well as the section on variables from outside PHP:

http://www.php.net/manual/en/language.variables.external.php

In short, register_globals = on is what'll create $name otherwise $name will not exist. Use $_GET['name'] instead.

🙂 Register Variables turned ON fixed it Thanks philipolson!

One thing to keep in mind, register_globals is considered a bad thing these days in the PHP world. Why? Having it on makes it easier to write bad code. Here are a couple more links on this topic:

Have fun :-)
