PHP - Apply Pagination To Search Results, Limit Pages

Hi,

my page is currently up at brewhas.org/transactions.php.  When I retrieve a set of results > the defined # per page (such as entering 'WI' for last name), I see the first page correctly, and see the links to next pages, but when I go to the next page there are no results displayed.  Same for p.3, etc.

So I've looked around enough to know that I need to pass a variable to the subsequent pages, either via a session variable or the URL.  I have 2 fields input on the form, as well as a limit and offset.  My questions are 1) do I need to pass all 4 and if so then should I use a session variable so the URL does not get too long, and 2) can anyone provide any help with setting session variables and including them to be passed?

I'm a newbie and have grabbed some code where I can but this is where i'm stuck.  thanks in advance.

Hi all,

I need your help as I have got a problem with display the 50 rows in the search results. I want to limit 50 rows in per page and if I have less than 50 rows like 21 rows in the page 2 then display the 21 rows.

I have got a problem with the limit, because when I tried to use `LIMIT 0, 50`, it will display total 71 rows which I only want to display no more than 50 in per page.

Here is what I have tried:

    $search_mailbox = $link->prepare("SELECT * FROM $folder WHERE from_email LIKE ? OR subject LIKE ? OR message LIKE ? ORDER BY received_date DESC LIMIT 0, 50");
    $search_mailbox->execute([$searchemail, $searchsubject, $searchmessage]);

And I have also tried this:

    $search_mailbox = $link->prepare("SELECT * FROM $folder WHERE from_email LIKE ? OR subject LIKE ? OR message LIKE ? ORDER BY received_date DESC LIMIT $offset, $limit");
    $search_mailbox->execute([$searchemail, $searchsubject, $searchmessage]);

It will not limit the rows I want. It will still show the 71 rows.

Here is the full code:

   

<?php
    
    // Initialize the session
    session_start();
    
    //Connect to the database
    require_once('config.php');
    
    $searchemail = '%' . 'gmail.com' . '%';
    $searchsubject = '%' . 'gmail.com' . '%';
    $searchmessage = '%' . 'gmail.com' . '%';
    
    $mailbox = $link->prepare("SHOW TABLES");
    $mailbox->execute();
    $folders = array();
    $total = 0;
    $total_rows = 0;
    $i = 0;
            
    while ($folder = $mailbox->fetch(PDO::FETCH_NUM)) {
        $folder = $folder[0];
    
        if (strpos($folder, 'users') !== false) {
            $folder = str_replace('users', '', $folder);
        }
        else
        {
            $folders[$i] = $folder;
        }
        $i++;
    }
    
    foreach($folders as $folder) {
        $search_mailbox = $link->prepare("SELECT * FROM $folder WHERE from_email LIKE ? OR subject LIKE ? OR message LIKE ? ORDER BY received_date DESC LIMIT 0, 50");
        $search_mailbox->execute([$searchemail, $searchsubject, $searchmessage]);
        
        if ($search_mailbox->rowCount() > 0) {
            $total += $search_mailbox->rowCount();
        }
    }
    
    $page = 1;
    $limit = 50;
    //$per_page = 50;
    //$pages = ceil($total / $per_page);
    
    $offset = ($page - 1) * $limit;
    
    
    foreach($folders as $folder) {
        
        $search_mailbox = $link->prepare("SELECT * FROM $folder WHERE from_email LIKE ? OR subject LIKE ? OR message LIKE ? ORDER BY received_date DESC LIMIT $offset, $limit);
        $search_mailbox->execute([$searchemail, $searchsubject, $searchmessage]);
    
    
        if ($search_mailbox->rowCount() > 0) {
            foreach($search_mailbox->fetchAll() as $k => $row) {
                $email_number = $row['id'];
                $search_from = $row['from_email'];
                $search_subject = $row['subject'];
                $total_rows++;
                echo $search_subject . '.........................' . $total_rows;
                echo "<br>";
            }
        }
                        
    }
    
    ?>

I am unable to fetch the first 50 rows in the page 1 and I am also unable to fetch the 21 rows in the page 2. 

What I am trying to achieve is when I am in page 1, I want to display the first 50 rows, then in the page 2 if I have another 50 rows then display the 50 rows, but if I have less than 50 rows like 21 rows then display the 21 rows.

Can you please show me an example how I can start with first 50 rows when I am in the page 1 then in page 2 display 21 rows to make in total 71 rows?

Any advice would be much appreicated.

Thanks in advance.

Good Evening,
I've been in a trial and error state for the past week trying to figure out how I can put on the pre-made pagination scripts I found on the web, but of no luck. I have just started programming like two weeks ago, and is still trying to understand logics and stuffs so I can get my desired output. So far, everything is doing well except for one - I am really having a hard time to incorporate pagination scripts with my code. To rank myself as a php programmer, I can say I am lower than one, and seemingly, what I want to achieve is an advanced code. Can anyone help me on what pagination code I should try to play with and incorporate with my code?

Here's my code so far:

<?PHP
include("dbconnection.php"); //Include database connection to file

$query = "SELECT * FROM records";

if(isset($_POST["btnSearch"]))

{
$query .= " WHERE last_name LIKE '%".$_POST["search"]."%' OR first_name LIKE '%".$_POST["search"]."%'OR territory LIKE '%".$_POST["search"]."%'OR job_title LIKE '%".$_POST["search"]."%'OR title LIKE '%".$_POST["search"]."%'OR employer LIKE '%".$_POST["search"]."%' ORDER BY territory ASC LIMIT 0,15"  ;

$result = mysql_query($query, $connection) or die(mysql_error());
} 

?>

Hi All,

I have a pagination script that works correctly when a user clicks on a category heading, however when I am using it to try an display search results it does not take into account the set of records to display per page, it just shows all results.


<?php


echo '<h3>Search Results</h3><br />';



$query = "SELECT count(*) from merchants WHERE name LIKE '%$_GET[q]%' OR short like '%$_GET[q]%' OR full like '%$_GET[q]%' OR keywords like '%$_GET[q]%'"; 
$row=mysql_fetch_assoc(mysql_query($query));
$total_records = $row['count(*)'];
$records_per_page = 5;
$total_pages = ceil($total_records / $records_per_page);
$page = intval($p);
if ($page < 1 || $page > $total_pages) $page = 1;
$offset = ($page - 1) * $records_per_page; 
 
$limit = " LIMIT $offset, $records_per_page";



$query = mysql_query("SELECT * FROM merchants WHERE name LIKE '%$_GET[q]%' OR short like '%$_GET[q]%' OR full like '%$_GET[q]%' OR keywords like '%$_GET[q]%' ORDER BY m_id  DESC") ; 
echo mysql_error() ;



while($row = mysql_fetch_assoc($query)){

$name = $row['name'];
$short = $row['short'];
$per = $row['percent'];
$m_id = $row['m_id'];

?>
    
    <div id="cbbox">
    <a href="viewm.php?m_id=<?php echo $m_id;?>">

        </div>
        <div class="cbimage">
         <img src="pimage/<?php echo $name;?>.gif" height="50px" width="100px" />
        </div>
      <div class="cbshort">

        </a>

<?php
}
if($total_records > 5)
{
for ($i = 1; $i <= $total_pages; $i++) {
echo "<a title='page $i p=$i'>Page $i -  </a>";
}
}

?>
</div>


if I echo out $total_records it displays the correct amount (7 in the case I am looking at)

Any ideas?
