How do you get search box's input terms into meta tags?

Right now I am using a session to get search's input terms and place them into meta tags(title). It works; the only issue is that the search terms lag 1 page behind.

 

For eg.

 

If i search "flowers" on first try, it will show flowers in the metas(title). Next I input "treehouse" in search; instead of "treehouse" showing in the metas, it'll still show me the previous term "flowers".  Now if I do a third search with a new term, it won't show the new term in metas, it'll show me the previous term "treehouse".

 

Why is this happening? Am I doing something wrong?

 

This is only an issue with meta tags. Search itself works fine. It shows results on a page as it's suppose to.

HI.

 

when do you set you session variable ?

 

Can you post your code here ?

 

 

Well my session_start(); is at the very begining of the page. My site setup is done in layers with header,head,footer,foot divded up; but here is a basic layout with my search session.

<?php init.php ?> //this includes the sesion_start();
<html>
<head>
	$searchsession	=	$_SESSION['searchsession'];
	
	<title><?php echo $searchsession; ?></title>
	<meta name="description" content="Search page description here." />
</head>
<body>

	<?php $value =  $_GET['search']; 
	
	  $_SESSION['searchsession']  =	$value;
	
	?>
	
	<form action="search.php?q=<?php echo $value; ?>" method="GET">
		<input type="search" name="search" maxlength="60" placeholder="Search...">
		<input type="submit" name="submit" value="Search" >
	</form>

</body>
</html>

It's simply down to the order you're processing the page -

 

Step 1 -

$searchsession	=	$_SESSION['searchsession'];

Let's say $_SESSION['searchsession'] = '1'; This line is setting $searchsession = '1';

 

Step 2 -

<title><?php echo $searchsession; ?></title>

You echo $searchsession, so the title will be '1'.

 

Step 3 -

$value =  $_GET['search']; 

You assign the variable $value the same value as $_GET['search'].. let's say that value is '2'.

 

Step 4

$_SESSION['searchsession']  =	$value;

You change the existing $_SESSION['searchsession'] variable to '2'.

 

Step 5 -

<form action="search.php?q=<?php echo $value; ?>" method="GET">

You echo the $value variable in your form, this is '2' as it's come from the $_GET['search'] variable.

 

Look at the order things are happening above. What you're looking for is step 1 - 5 the variable to always be 2.

 

By changing the order of the 5 steps above you'll get what you want.

Thanks for pointing me the right direction.  I was getting confused sessions and variables because I had divided up the pages/sections; but by playing around with it more, I finally came to a solution. It works now.
