Hi

I have a database search results page that I would like to paginate but as it moves from the first page to the next page it loses the value of the search term.

ie

The recordset is
<?php
$search_rs = new WA_MySQLi_RS("search_rs",$connection,10);
$search_rs->setQuery("SELECT * FROM items WHERE items.itemTitle LIKE '%".$_POST['search']."%' ORDER BY items.itemTitle ASC");
$search_rs->execute();
?>
with 'search' being POSTed from another page.

This successfully produces a list of 10 results using ...

<?php
while(!$search_rs->atEnd()) {
?>

<tr>
<td><?php echo($search_rs->getColumnVal("itemNo")); ?></td>
<td><?php echo($search_rs->getColumnVal("itemTitle")); ?></div></td>
</tr>

<?php
$search_rs->moveNext();
}
$search_rs->moveFirst();
?>

Adding and clicking the link

<a href="<?php echo $search_rs->getNextPageLink(); ?>">Next</a>

before the results listing gives "undefined index" for the query ie it has lost the 'search' value.

Hope that this makes sense.

Would be grateful for any suggestions to solve this.

Thanks

Andrew

change the next link:

<a href="<?php echo $search_rs->getNextPageLink(); ?>">Next</a>



to:

<a href="<?php echo $search_rs->getNextPageLink(); ?><?php echo(isset($_POST['search'])?"&". $_POST['search']:""); ?>">Next</a>




then add the following at line 1:

<?php
if(isset($_GET['search'])) {
$_POST['search'] = $_GET['search'];
}
?>

Hi

I've done as you said - copied and pasted.

It lists the first ten results correctly and then again on page two loses the value of the variable and lists the entire database.

Notice: Undefined index: search in C:\wamp_php5_5\www\sheffieldarchives\database_admin\admin_search_library_results.php on line 9

where line 9 is

$search_rs->setQuery("SELECT * FROM items WHERE items.itemTitle LIKE '%".$_POST['search']."%' ORDER BY items.itemTitle ASC");

(Point of clarification - I've no knowledge of php - I've added

<?php
if(isset($_GET['search'])) {
$_POST['search'] = $_GET['search'];
}
?>

immediately above the pagination code. I assume that is what you meant.

Thanks in anticipation

Andrew

no, this code:
<?php
if(isset($_GET['search'])) {
$_POST['search'] = $_GET['search'];
}
?>

needs to go at line 1, not above the pagination.

That is where I originally placed it - but then I thought about it too much!

I have put it at Line 1 - and it has made no difference.

I'll need to troubleshoot directly, see the private message section.


please send a link to your site where i can see the problem occur and ftp login details so I can access the site files directly to troubleshoot.

i am not able to reproduce.

I go to the search page, enter test and hit the submit button, no error.

on clicking the next button, i still don't see an error.

I see, I was looking for the error you reported, not paying attention to the results.

Sorry, the code for the next link:

<a href="<?php echo $search_rs->getNextPageLink(); ?><?php echo(isset($_POST['search'])?"&". $_POST['search']:""); ?>">Next</a>


should be:
<a href="<?php echo $search_rs->getNextPageLink(); ?><?php echo(isset($_POST['search'])?"&search=". $_POST['search']:""); ?>">Next</a>
