Passing Variables

rowantrimmer

Hello,

I have a few variables $count, $number, $effect & $location that I want to pass onto another php page without having to put them into a form as the next page is loaded automatically using an html tag.

Any ideas ?

Many thanks

Rowan

You could use sessions (or cookies), or if feasible pass using the query string, i.e. $_GET.

Could you possibly give me an example of how I could use $_GET ? or session cookies ?

Many thanks

echo '<a href="nextpage.php?count=' . $count . '&number=' . $number . '&effect=' . $effect . '&location=' . $location . '">Next Page</a>';

You may need to url encode the variables first, though.
Then on nextpage.php you would access using $GET['count'], $GET['number'] etc.

I'm not entirely sure if this will work with a meta refresh, as you apparently are trying to do.

does the same apply for action targets in forms?
i.e <form method=post action="<?php echo $PHP_SELF.'?action=blah';?>">

caus it doesnt seem to pass the variable to the url

It should, if I remember correctly.

Please help I am really struggling.

I have attached the 2 php files. The first shows the variables that I am trying to pass to the new one. As you can see my code for property.php is wrong.

<?php

include ("world_var.php");

$db = mysql_connect("localhost", $world_user,$world_pass);

mysql_select_db($world_data,$db);

$sql = "SELECT * FROM property";

$prop = mysql_query($sql);

$proprow = mysql_fetch_array($prop);

$$propcount=mysql_num_rows($prop);

$$prop_counter=12;

$sql = "SELECT * FROM flash";

$flash = mysql_query($sql);

$flashrow = mysql_fetch_array($flash);

$$flashcount=mysql_num_rows($flash);

$$flash_counter=99;

<html>

<head>

echo '<a href="property.php?propcount=' . $propcount . '&prop_counter=' . $prop_counter . '&flashcount=' . $flashcount . '&flash_counter=' . $flash_counter . '">Next Page</a>';

</body>

</html>

Property.php

<?php

$propcount=$_GET['propcount'];

?>
<html>
<head>
<title>Orchards Rolling Screen Application (Startup Page)</title>
<meta http-equiv="Page-Enter"content="revealTrans(Duration=2.0,Transition=<?php echo $scroll ?>)">
<meta http-equiv="refresh" content="100"; URL=main.php?splash=<? echo $HTTP_GET_VARS['splash'];?>">
<meta HTTP-EQUIV="imagetoolbar" CONTENT="no">
<link rel="stylesheet" href="body.css">
</head>
<body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" style="overflow:hidden">

</body>
</html>

Here is a little test of mine:

trans0.php

<html>
<head>
<title>Form Page</title>
</head>
<body>
<form action="trans1.php" method="post">
<input type="text" name="testvar">
<input type="submit" value="Submit">
</form>
</body>
</html>

trans1.php

<?php
if (!empty($_POST['testvar']))
	$testvar = stripslashes($_POST['testvar']);
?>
<html>
<head>
<title>Transition Page</title>
<meta http-equiv="refresh" content="2; url=trans2.php?testvar=<?php echo rawurlencode($testvar); ?>"> 
</head>
<body>
Please wait to be transferred, or click <a href="trans2.php?testvar=<?php echo htmlspecialchars($testvar); ?>">here</a>.
</body>
</html>

trans2.php

<?php
if (isset($_GET['testvar']))
	echo htmlspecialchars(stripslashes($_GET['testvar']));
else
	echo 'error';
?>
