Pass the value of a variable to another page

How do you pass the value of a variable on to another page?

I've tried the following:

... .php?varname=varname1
... .php?varname=$varname1
... .php?varname-<?php echo $varname1 ?> - I get an error with this one

on the other page I echo varname and it gets displayed exactly as it is above (either varname1 or $varname1).

If it is outside of the php <? ?> brackets...

<a href="http://www.blah.com/blah.php?varname=<?= $vaiable ?>">Link</a>

If it is inside of the php <? ?> brackets...

echo "<a href=\"http://www.blah.com/blah.php?varname=".$variable."\">Link</a>";

And just to clear up any confusion you may have, it will set $_GET['varname'] (not $varname, as older tutorials would lead you to believe) on the next page.

James0816

thx...still not passing a value. Here's the redirect code:

TheDefender

Thanks for the follow-up Mordecai...

In other words, on the next page, you would have to echo it like so:

echo $_GET['varname'];

// OR

echo $_REQUEST['varname'];

// OR (not recommended)
extract($_GET);
echo $varname;

yepper to the $_GET statement. that is working coming from another page.

TheDefender

Outside the PHP <? ?> Brackets:

<meta http-equiv="refresh" content="1;url=../AddEdit.php?mname=<?= $sname; ?>">

Inside the PHP <? ?> Brackets:

echo "<meta http-equiv=\"refresh\" content=\"1;url=../AddEdit.php?mname=".$sname."\">";

James0816

sry...still a no go.

TheDefender

OK, when you say nogo, let me ask you this... Is the page refreshing to the right place first of all?

Like So:
http://www.yourdomain.com/AddEdit.php?mname=xxxxxx
(where the xxxxxx is the sname value)

If so, then on that page, what do you get when you do:
echo $_GET['mname'];

If not, then what does the URL read when it redirects? Or does it even redirect at all? What exactly is happening?

James0816

Here's what it looks like:

<html>
<?php
$sname="Bob"
?>
<head>
<meta http-equiv="content-type" content="text/html;charset=iso-8859-1">
<title>golive_test</title>
<meta http-equiv="refresh" content="1;url=../AddEdit.php?mname=".$sname."\"">
<link href="../style_Verdana.css" rel="stylesheet" media="screen">
</head>

This is the result:

{h}ttp://localhost/TestSite/AddEdit.php?mname=

TheDefender

<html>
<?php
$sname="Bob"
?>
<head>
<meta http-equiv="content-type" content="text/html;charset=iso-8859-1">
<title>golive_test</title>
<meta http-equiv="refresh" content="1;url=../AddEdit.php?mname=<?= $sname; ?>">
<link href="../style_Verdana.css" rel="stylesheet" media="screen">
</head>

OK, so you are OUTSIDE of the <? PHP ?> brackets... So, make the change like I did above...

James0816

I have three pages in all.

The first page contains the the link to pass the variable to the second page

AddEdit.php?mname=<?php $Test->Value('name') ?>

(This is displayed as .....mname=Bob)

The second page is the update page where you can change information. There is a submit button on that page. After making changes and clicking Submit, it goes to a confirmation page (update_confirm.php). This page displayes some information saying the the update was successfull.

Now I want it to go back to the AddEdit.php and be able to pull up that same record which is why I am trying pass the same value back (i.e. $sname='Bob').

It does do the redirect however the page comes up as empty. In the address line it has

{h}ttp://localhost/TestSite/AddEdit.php?mname=

when I thought it was supposed to have this:

{h}ttp://localhost/TestSite/AddEdit.php?mname=Bob

Hope this helps. Let me know if you need more info.

TheDefender

OK, look at the change I referenced in my last post.

James0816

That's got her.....can you explain that to me? something new introduced to me there

=<?= $sname; ?>

the second "=" sign.

TheDefender

Remove it from the line, and look at it alone for a second. It is a shorthand variation for PHP. I am not sure exactly what it's called, but look at the 3 examples below:

<?= $sname; ?>

EQUALS

<?PHP echo $sname; ?>

EQUALS

<?
echo $sname;
?>

Probably doesn't have a name, but the generic liguistic term for this sort of abbreviation is "syncopation". Note that it won't work if short_tags is turned of (but then, <? won't work either).
