Passing Values to another Page w/o a Form

[estrellas]

Hey guys -

I"m working with a lot of php/mysql databases here, and in order to update account information here's the code we use ...

	printf ("\n<form method=\"post\" action=\"mailadd.php\">\n");
	printf ("<input type=\"hidden\" name=\"geo_type\" value=\"rectangle\">\n");
        if ($usecookies == 0) {
	  printf ("<input type=\"hidden\" name=\"userid\" value=\"%d\">\n", $userid);
	  printf ("<input type=\"hidden\" name=\"passwd\" value=\"%s\">\n", $passwd);
        }
#	echo '<input type="Submit" name="submit" value="Enter a rectangle mail rule">';
	echo '<input TYPE="image" src="button-rectangle.jpg"></form><br>';
	echo "</form>\n";

now...my job is to redesign this site, etc, and to make it where we don't need the forms to send information from page to page.

How do you do that? I really don't know that much about php to know how to do it.

Thanks much in advance.

You can use sessions or pass them in url

URL:

http://your.site.here/target.page?variable=value

Sessions:

//Used to initialize the session superglobal
//Must be the first line on the page and must be done
//on every page you use session data on
SESSION_START();

//Puts $value into the session section "variable.name"
$_SESSION['variable.name'] = $value;

//Retrieves the value from session data
$value = $_SESSION['variable.name'];

I agree with Matt, use sessions. Passing a URL can be very ugly, people bookmark them and as it is limited in length.f you have a cluster of servers you will have to use a database based session handler rather than the default file implementation.

hmm .. interesting .. thanks

if i passed them through a URL ... how would I pass multiple values ...

would this work?

http://www.mysite.com/username=$username&password=$password

where $username and $password are two different unique variables per session?

if you do go the URL route your example is alomist correct as far as code goes but it sohuld like like

http://www.mysite.com?username=fred&password=basset

as by the timethis happens php has droped out of the picture and real values need to be seen.
As you will know passing clear text passwords in clear view is not so good !!

ouch thanks ... i think i'll just go with session variables ... it'll be a little more secure as i understand it

Going with session variables makes your URL 'prettier' and avoids probing by crafting specific URL parameters.

All you need is to start each script with session_start():

<?php
session_start();

# assign var:
$_SESSION['myVar'] = 'whatever';

# retrieve (in any script that uses session_start()):
echo $_SESSION['myVar'];
?>
