$_GET variable question

[stephane]

I have a file.php in which a created dynamic hypertext links and send a
variable $row[0]

echo "<td><a href='modify_re quest.php?$row[0]'>$row[0]</a></td>";

I can see in the url on modify_request. php the variable value.

But I can't get it in another variable in modify_request. php

here is a simple example of what I am trying to do with file1
=============== =============

<?php
$var1 = 2;
echo "<a href='get_it.ph p?$var1'>click here</a>";
?>

and in file2 I try to use the variable $var2
=============== ===============

<?php

$var2= $_GET[var1];

print "$var2";

?>

=============== ===============
in that example, it doesn't print $var2...

can someone tell me what misses to make this work please?

Since you're not using a name=value combination, it isn't assigned to
any key in the $_GET array. What you rather need to do in the example,
is:

=============== =============== =====
<?php
// file1

$var1 = 2;
echo "<a href=\"get_it.p hp?var1=".$var1 ."\">click here</a>";
?>
=============== =============== =====
<?php
// file2

$var2 = $_GET["var1"];
echo $var2;
?>
=============== =============== =====

Re: $_GET variable question

You also could get the whole string behind the "?" from
$_SERVER['QUERY_STRING']

Re: $_GET variable question

a little tip that is not actually the problem here but it migth com in
handy in the future...whenev er you use the $_GET into an if statement
remember to use the isset() function.


if (isset($_GET['var']))

is better then:


if ($_GET['var'])

they should both work but the second may sometime give you some
problems...
