I have a little script that have a Previous & Next button.
My problem is I want to detect & place the ID in those buttons
this is the code from the pagination
<body>
<?php include_once 'data.php'; ?>
<center>
<ul class="pagination">
<?php
if($page_counter == 0){
echo "<li><a href=?start='0' class='active'>0</a></li>";
for($j=1; $j < $paginations; $j++) {
echo "";
}
}else{
echo "<a href=?start=$previous><button>Previous</button></a>";
for($j=0; $j < $paginations; $j++) {
if($j == $page_counter) {
echo " ";
}else{
echo " ";
}
}if($j != $page_counter+1)
echo "<a href=?start=$next><button>Next</button></a>";
}
?>
</ul>
</center>
In this part I have the ID but the problem is I can`t get it with this example to place it into the pagination.
<?php
foreach($result as $row) {
echo '
<div class="card"><button1>
'. $row['notice_id'] .'
<div class="time-left">
<div class="dropdown1">
' ;
}
}
else {
echo '';
}
$conn->close();
?>
</div></div>
This is the code from data.php I think I need to place some code into for detection from the ID
<?php
//include configuration file
require 'configuration.php';
$start = 0; $per_page = 1;
$page_counter = 0;
$next = $page_counter + 1;
$previous = $page_counter - 1;
if(isset($_GET['start'])){
$start = $_GET['start'];
$page_counter = $_GET['start'];
$start = $start * $per_page;
$next = $page_counter + 1;
$previous = $page_counter - 1;
}
// query to get messages from messages table
$q = "SELECT * FROM group_notice LIMIT $start, $per_page";
$query = $db->prepare($q);
$query->execute();
if($query->rowCount() > 0){
$result = $query->fetchAll(PDO::FETCH_ASSOC);
}
// count total number of rows in students table
$count_query = "SELECT * FROM group_notice";
$query = $db->prepare($count_query);
$query->execute();
$count = $query->rowCount();
// calculate the pagination number by dividing total number of rows with per page.
$paginations = ceil($count / $per_page);
?>
You can use some formulas for calculate limit and offset of results.
For example you have 100 records, and you want to paginate it into 10 records per page, and the formula is like below.
// Get Page from Query String
$page = 1;
if(!empty($_GET["page"])){
$page = $_GET["page"];
}
// Get record count
$count_query = "SELECT * FROM group_notice";
$query = $db->prepare($count_query);
$query->execute();
$count = $query->rowCount();
$per_page = 10; // records per page
$pages = ceil($count/$per_page); // get total page
$start = $page * $per_page - $per_page; // get offset
// Do something with your records
$query = db->prepare("SELECT * FROM group_notice LIMIT ?, ?");
$query->bind_param("ii", $start, $per_page); // you should use bind param if you use prepared statement
$query->execute();
if($query->rowCount() > 0){
$result = $query->fetchAll(PDO::FETCH_ASSOC);
}
if($page > 1){
echo 'Prev'; // Print Prev Page
}
for($i = 1; $i <= $pages){
echo ''.$i.''; // Print Page Number
}
if($page < $pages){
echo 'Next'; // Print Next Page
}
Hope it helps.

I have a php pagination page with post submit by user to search something, query mysql in first page is ok, but in NEXT page, i have get white blank page.
Below is the paging code.
$_SESSION['nationality'] = $_POST['nationality'];
$reclimit = 2;
if(isset($_GET['page'])){
$page = $_GET['page'];
} else {
$page = 1;
}
$start = (($page-1) * $reclimit);
$sql = "SELECT userid, name, LEFT(hkid, 4) as hkid, description, nationality, photo_1, photo_2, photo_3 FROM $tbl_name WHERE `nationality` LIKE '%$_SESSION[nationality]%'";
$records = $con->query($sql);
$total = $records->num_rows;
$tpages = ceil($total / $reclimit);
$rec = "SELECT userid, name, LEFT(hkid, 4) as hkid, description, nationality, photo_1, photo_2, photo_3 FROM $tbl_name WHERE `nationality` LIKE '%$_SESSION[nationality]%' LIMIT $start, $reclimit";
$records = $con->query($rec);
while ($row = mysqli_fetch_assoc($records)){
// Loop record
}
// Paging
echo '<ul class="pagination pagination-lg">';
for( $i=1; $i <= $tpages; $i++ ) {
$active = $i == $page ? 'class="active"' : '';
echo "<li $active ><a href='$_SERVER[PHP_SELF]?page=" .$i. "'>" .$i. "</a></li>";
}
echo '</ul>';
This works for me:
<?php
$limit =3;
if (!isset($_GET['pg'])) {
$pg = 1;
} else {
$pg = $_GET['pg'];
}
$start = ($pg - 1 ) * $limit;
$sql = "SELECT * FROM tableName LIMIT $start , $limit";
?>
ok si im not very fimiliar with PDO im just starting off, could someone help me here why my results will not display? the pages are working but no data would show ..
<?php
require_once 'db/_db.php';
$stmt = $db->prepare("SELECT * FROM article");
$stmt->execute();
$result = $stmt->fetchAll();

//$base_url = 'https://localhost/pagi/'; //
global $per_page;
$num_links = 4;
$total_rows = $total_rows;
$cur_page = 1;
if(isset($_GET['page']))
{
$cur_page = $_GET['page'];
$cur_page = ($cur_page < 1)? 1 : $cur_page; //if page no. in url is less then 1 or -ve
}
$offset = ($cur_page-1)*$per_page; //setting offset
$pages = ceil($total_rows/$per_page);
$start = (($cur_page - $num_links) > 0) ? ($cur_page - ($num_links - 1)) : 1;
$end = (($cur_page + $num_links) < $pages) ? ($cur_page + $num_links) : $pages;
//$res = mysql_query("SELECT * FROM article ORDER BY id DESC LIMIT ".$per_page." OFFSET ".$offset);
$stm = $db->prepare("SELECT * FROM article ORDER BY id DESC LIMIT ".$per_page." OFFSET ".$offset);
$stm->execute();
$res = $stm->fetchAll();
$rows = $stm->rowCount();
if($rows < 1){
header("Location: news-events.php");
exit;
}
if(is_resource($result))
{
foreach( $res as $row ) {
$desc = $row["ne_article"];
$img = $row['ne_image'];
if(!empty($img)){

would really appreciate your time and help
You are doing nearly everything wrong. And you did with old mysql as well
To get the number of records in database you should never select all the rows, nor fetch them. You have to select the count already.
$total_rows = $pdo->query("SELECT count(1) FROM article")->fetchColumn();
is how it have to be done with PDO.
Besides, for the other query you should use prepared statements.
Finally, you have to take out all the useless verifications and start with foreach right away:
$stm = $db->prepare("SELECT * FROM article ORDER BY id DESC LIMIT ?,?");
$stm->execute([$offset,$per_page]);
$res = $stm->fetchAll();
foreach( $res as $row ) {
And read up on setting the error mode properly here.
check if you have problem with the quotes... when you echo html code inside ' ' if you have " " and again inside '' like this example echo ' " '' " ' you will have problem. you should use \' in order to avoid these problem here echo ' '.$dir.' ';
I used this code in my all pages. Everywhere this code work well. In case of my search page this code count all page by search words but when I click next(2nd or 3rd) page, its cannot display any item. That means sql query for 2nd or 3rd or any others pages not worked. No error also. Pagination page url goes well also.
My Search code:
if(isset($_POST['searchword'])){
$w = mysqli_real_escape_string($dbh, $_POST['searchword']);
$q = strip_tags($w);
$q = trim ($w);
$limit = 12;
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * $limit;
$sql = "SELECT * FROM search_data WHERE MATCH(detail) AGAINST('+$q*' IN BOOLEAN MODE) ORDER BY id ASC LIMIT $start_from, $limit";
$execute = $dbh->query("$sql");
$rowcount = $execute->num_rows ;
if ($rowcount > 0 ) {
$row = $dbh->query($sql) ;
while ($row = $execute->fetch_assoc()) {
$detail = $row['detail'];
$url = $row['url'];
echo $detail;
}
}
}
//Pagination
$sql = "SELECT COUNT(id) FROM search_data WHERE MATCH(detail) AGAINST('+$q*' IN BOOLEAN MODE)";
$result = mysqli_query($dbh,$sql);
$row = mysqli_fetch_row($result);
$total_records = $row[0];
if($total_records > 0){$total_pages = ceil($total_records / $limit); }
$pagLink = "<ul class='pagination'>";
if(!empty($total_pages)){for ($i=1; $i<=$total_pages; $i++) {
$pagLink .= "<li><a href='".$thispage."?page=".$i."'>".$i."</a> </li>";
};
echo $pagLink . "</ul>";
}
I have few records in MySQL DB table.
Displayed those records with pagination PREV and NEXT.
Page ids are displaying in url bar.
http://localhost/pagination.php?page=5
I don't want them while pagination clicking.
How can i do this?
Here is my code.
<?php
mysql_connect("localhost", "root", "");
mysql_select_db("moodle");
$per_page = 10;
$pages_query = mysql_query("SELECT COUNT('id') FROM question");
$pages = ceil(mysql_result($pages_query, 0) / $per_page);
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;
$query = mysql_query("SELECT * FROM question LIMIT $start, $per_page");
while($query_row = mysql_fetch_assoc($query)){
echo $query_row['id']."<br />";
}
$prev = $page - 1;
$next = $page + 1;
echo "<a href='pagination.php?page=$prev'>Prev</a> ";
if($pages >= 1){
for($x=1; $x<=$pages; $x++){
echo ''.$x.' ';
}
}
echo "<a href='pagination.php?page=$next'>Next</a> ";
?>
Use id in session and don't display it in url . other method is to use Ajax call in pagination on click of previous or next button . i think these are two simple solutions for you that you can easily manage .
I used Pagination in php with mysqli and Alphabetical navigator in same page. They are working well. But if I click on any Alphabet like: B Its display 10 sql table's data with B and when I click page 2 to display rest of data Alphabet B, Its cannot display rest of data B but display next 10 data of all sql table's.
I have Total 100 row in sql where for A=20, b=30, c=5, d=15 ... etc. I used Pagination for display 10 data at a time And Alphabetical navigator to display data as Alphabet.
Now I want:
When user load my page, Pagination work for all data by name ASC limit 10, But when user click on any Alphabet, Pagination work for this Alphabet.
Here is my code:
<?php
include_once('db.php');
//for pagination
$limit = 10;
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * $limit;
//for Alphabet
$sort = isset($_GET['firstLetter']) ? filter_input(INPUT_GET, 'firstLetter',FILTER_SANITIZE_URL) : "" ;
if($sort == "") {
$sql = "SELECT * FROM evideo ORDER BY name ASC LIMIT $start_from, $limit";
}else{
$sql = "SELECT * FROM evideo WHERE Name LIKE '$sort%' ORDER BY name ASC LIMIT $start_from, $limit" ;
}
$execute = $dbh->query("$sql");
//Display Alphabet
echo '<div class="well abc-pag"><b>Find Alphabetically:</b> ';
for ($i = 65; $i < 91; $i++) {
printf('%s ', $_SERVER['PHP_SELF'] , chr($i), chr($i));
}
printf('ALL', $_SERVER['PHP_SELF'] );
echo "</div>";
$rowcount = $execute->num_rows ;
$c = 1;
if ($rowcount > 0 ) {
$row = $dbh->query($sql) ;
while ($row = $execute->fetch_assoc()) {
$name = $row['name'];
$Detail = $row['Detail'];
$link = $row['link'];
$pic = $row['pic'];
if (empty($pic)) $pic = "../images/edir.jpg";
echo '<article class="white-panel"><a href="'.$link.'">';
echo '<img src="images/loader.gif" border="0" data-echo="'.$pic.'" class="emusicpro img-responsive"></a>';
echo '<div class="well"><strong>'.$name.'</strong><br>'.$Detail.'</div>';
echo '</article>';
}
} else {echo '<p align="center"><b>No Data Found.</b></p>';}
//Display pagination
$sql = "SELECT COUNT(id) FROM evideo";
$rs_result = mysqli_query($dbh,$sql);
$row = mysqli_fetch_row($rs_result);
$total_records = $row[0];
$total_pages = ceil($total_records / $limit);
$pagLink = "<ul class='pagination'>";
for ($i=1; $i<=$total_pages; $i++) {
$pagLink .= "<li><a href='ebox2.php?page=".$i."'>".$i."</a></li>";
};
echo $pagLink . "</ul>";
