I think the error is in your search.php page code. You need to change your ending limit.
$limit = 5;
if (isset($_GET['page'])) {
$page = $_GET['page'];
}else{
$page = 1;
}
$start_from = ($page-1) * $limit;
$search = $_GET['search'];
$sql = "SELECT * FROM job_post WHERE jobtitle LIKE '%$search%' ORDER BY id_jobpost DESC LIMIT $start_from, $limit";
When you are on the first page, you are doing: LIMIT 0, 5. When you are on the second page, you are doing: LIMIT 5, 5.
I suggest:
$limit = 5;
if (isset($_GET['page'])) {
$page = $_GET['page'];
}else{
$page = 1;
}
$start_from = ($page-1) * $limit;
$end_at = $page * $limit;
$search = $_GET['search'];
$sql = "SELECT * FROM job_post WHERE jobtitle LIKE '%$search%' ORDER BY id_jobpost DESC LIMIT $start_from, $end_at";
However I also noticed that in your search page you are doing a query inside of a query, I think a better way to do this is with a join so you only hit the database once. I don't know the structure of your database but the below code is an example of a better way to go about it so that you only hit the database once:
<?php
session_start();
require_once("db.php");
$page_size = 5;
if (isset($_GET['page'])) {
$page = $_GET['page'];
}else{
$page = 1;
}
$start_from = ($page-1) * $page_size;
$end_at = $page * $page_size;
$search = $_GET['search'];
$sql = "
SELECT
j_p.*,
c.*
FROM
job_post j_p,
company c
WHERE
jobtitle LIKE '%$search%'
and c.id_company = j_p.id_companyname
ORDER BY
id_jobpost DESC
LIMIT
$start_from,
$end_at
";
$result=$conn->query($sql);
if ($result->num_rows>0) {
while($row1 = $result1->fetch_assoc()) {
?>
<div class="attachment-block clearfix">
<img class="attachment-img" src="uploads/logo/<?php echo $row1['logo']; ?>" alt="Attachment Image">
<div class="attachment-pushed">
<h4 class="attachment-heading"><?php echo $row1['jobtitle']; ?> <span class="attachment-heading pull-right">₱<?php echo $row1['maximumsalary']; ?>/Month</span></h4>
<div class="attachment-text">
<div><strong><?php echo $row1['companyname']; ?> | <?php echo $row1['province'].",".$row1['city']; ?> | Experience Required(in years): <?php echo $row1['experience']; ?></strong></div>
</div>
</div>
</div>
<?php
}
}else{
echo "<center><strong>No Job Matched!</strong></center>";
}
$conn->close();
?>
