Basic PHP question

#1 (**permalink**) 01-20-2004

Greetings,
I have a page called test.php. I want to call the same page but pass a
variable to
it so that data on the page (retrieved from mysql database ) changes.

So, can I have inside test.php a call to test.php with a variable ?

thanks,
Darryl

Of course! It would go something like this:

<html>
<head>title</head>
<body>
<?php if ($somevar) {
# make data call here returning some data
?>
This is page with somevar.
<?php } else { ?>
This is without somevar.
<php } ?>
</body>
</head>

$somevar could be sent by post (form) or get (query string).

Hi Darryl,

you can call the page directly with variables like:
test.php?your_var=1&another_one=testing

or you can eventually use some form:
echo "<form action=\"test.php?your_var=1\" method=\"post or get\">";

instead of \"test.php?your_var=1\", you can try also the $_PHPSELF variable
and use the fields (hidden or normal) from your form..

Lot of fun..

Greetz,
Damir

Your code is deprecated

use this one below

<html>
<head>title</head>
<body>
<?php if ($_REQUEST["somevar"]) {
# make data call here returning some data
?>
This is page with somevar.
<?php } else { ?>
This is without somevar.
<php } ?>
</body>
</head>

I would recommend that you use the $_POST['somevar'] or respective the
$_GET['somevar'] vars to read your parameter from the header. Of course,
Tyrone sample is good and work perfekt, but also if you start php coding,
learn how to use parmeter in a more secure way.

You can build a link to parse a varialbe to your page:

echo '<a href="test.php?var=' . $value . '">sent var</a>';
if (issset($_GET['var']))
echo $_GET['var'];

One more question then.
say I have defined:
$adj = -60;

and then in a loop I do:
$adj = $adj - 30;

then I want to have something like:
-30px

how do I convert to string and concatinate the px on the end?
I still need $adj to be numeric so I can subtract from it on the next
loop iteration.

thanks,
Darryl

Nevermind, I figured it out.
strval() is my friend.
