Question
hello kind sirs can you help me with this code. What i try to do is when i type something in the search box, ex. pending it will show the 5 pending reservation per page(5 rows of pending reservation). but when i try it, it shows all the pending reservation which is more than 10.
here is the image
i try something like this.. but it shows nothing
$query = "SELECT * FROM reservations WHERE CONCAT(firstname, lastname, reservationstatus)LIKE '%".$valueToSearch."%' LIMIT " . $this_page_first_result . ',' . $results_per_page";
Here is the whole code
<?php
error_reporting(E_ALL & ~E_NOTICE);
error_reporting(E_ERROR | E_PARSE);
session_start();
?>
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "srdatabase";
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error)
{
die("Connection failed: " . $conn->connect_error);
}
$results_per_page = 5;
$select= "SELECT * FROM reservations";
$result = mysqli_query($conn, $select);
$number_of_results = mysqli_num_rows($result);
if(!isset($_GET['page']))
{
$page = 1;
}
else
{
$page = $_GET['page'];
}
$this_page_first_result = ($page-1)*$results_per_page;
$sql = "SELECT * FROM reservations LIMIT " . $this_page_first_result . ',' . $results_per_page;
$result = mysqli_query($conn, $sql);
$number_of_pages = ceil($number_of_results/$results_per_page);
?>
<div id="paging-div">
<?php
for($page=1;$page<=$number_of_pages;$page++)
{
echo '<a id="pagingLink" href="adminControl.php?page=' . $page . '">' . $page . '</a>';
}
?>
<?php
if(isset($_POST['search']))
{
$valueToSearch = $_POST['valueToSearch'];
$query = "SELECT * FROM reservations WHERE CONCAT(firstname, lastname, reservationstatus)LIKE '%".$valueToSearch."%'";
$search_result = filterTable($query);
}
else
{
$query = "SELECT * FROM reservations";
$search_result = filterTable($query);
}
function filterTable($query)
{
$conn = mysqli_connect("localhost", "root", "", "srdatabase");
$filter_Result = mysqli_query($conn, $query);

... when i try it, it shows all the pending reservation which is more than 10.
That's because when you hit 2nd, 3rd, ... pages(after navigating from the 1st page), the $_POST array would be empty ie $_POST['search'] won't be set, and that's why else{...} part of the code will get executed every time you navigate to 2nd, 3rd, ... pages. Since you're not sending any sensitive data with the form, use GET instead of POST in the method attribute of the form, like this:
<form action="..." method="get">
and get the user inputted data like this:
if (isset($_GET['search'])) {
$valueToSearch = $_GET['valueToSearch'];
...
Subsequently, you need to attach that search query in each of your pagination links, so that the search query would be available when you hop from page to page.
// your code
<?php
for($page=1;$page<=$number_of_pages;$page++)
{
echo "<a id='pagingLink' href='adminControl.php?page=" . $page . "&valueToSearch=". urlencode($_GET['valueToSearch']) ."&search'>" . $page . "</a>";
}
?>
// your code
