storing the value of GET variable - php

Question

I have a search bar on the first page and the results are shown on the second page with pagination. The problem is the pagination isn't working with $_GET or $_POST variable.
what I meant is like when the form is submitted the url on second page changes to something like
products.php?search=something and I am able to see the results that show up.
However when I hit the next button of the pagination I get undefined index search error and the url changes to products.php?page=2
so is there any way that I can store the $_GET['search']; value so that I can use it when the page number changes?
<form action="products.php" method="post">
<input type="text" name="search">
<input type="Submit">
</form>
products.php
<?php
/*
* Connect to the database (Replacing the XXXXXX's with the correct details)
*/
try
{
$dbh = new PDO('mysql:host=localhost;dbname=db', 'root', '');
}
catch(PDOException $e)
{
print "Error!: " . $e->getMessage() . "<br/>";
die();
}
/*
* Get and/or set the page number we are on
*/
if(isset($_GET['page']))
{
$page = $_GET['page'];
}
else
{
$page = 1;
}
/*
* Set a few of the basic options for the class, replacing the URL with your own of course
*/
$options = array(
'results_per_page' => 100,
'url' => 'products.php?page=*VAR*',
'db_handle' => $dbh
);
$q = $_GET['search'];
/*
* Create the pagination object
*/
try
{
$paginate = new pagination($page, "SELECT * FROM products where title LIKE '%$q%' order by id desc", $options);}
catch(paginationException $e)
{
echo $e;
exit();
}
if($paginate->success == true)
{
$paginate_result = $paginate->resultset->fetchAll();
foreach($paginate_result as $row)
{
echo $row['title'];
}
?>
<?php echo "<li>"; //this is next and prev button for the pagination class if results exceed the limit.
echo $ball->links_html;
echo "</li>"; ?>

Answer 1

Change your code to something like this ...
<form action="products.php" method="get">
<input type="text" name="search">
<input type="Submit">
</form>
... and ...
$options = array(
'results_per_page' => 100,
'url' => 'products.php?search=' . urlencode($_GET['search']) . '&page=*VAR*',
'db_handle' => $dbh
);

Answer 2

The easiest solution would probably be to use a hidden field in your form:
<form action="products.php" method="post">
<input type="text" name="search">
<input type="hidden" name="page" value="<?php echo $_GET['page']; ?>">
<input type="Submit">
</form>

Try Session variables, they let you store it until the browser is closed(or you switch to another website maybe?) and store it across pages.

The other alternative is cookies, which will let you store for just about as long as you want unless the user deletes their cookies.
