i have this code pagination and this code for quiz after click to next saves session and header(location) to next page for quiz.
now i want to load next page without refresh page after click to input next load next page ...
<?php
$cid = (int)$_GET['id'];
if(!isset($_GET['page'])){
$page = 1;
}else{
$page = (int)$_GET['page'];
}
$records_at_page = 1;
$q = $db->query("SELECT * FROM `questions` WHERE `cat`='".$cid."'");
$records_count = $q->num_rows;
$pages_count = (int)ceil($records_count / $records_at_page);
if(($page > $pages_count) or ($page <= 0)){
die('No More Pages');
}
$start = ($page - 1) * $records_at_page;
$end = $records_at_page;
$next = $page + 1;
$prev = $page - 1;
$qui = isset($_POST['val']);
if(isset($_POST['next'])){
$tst = $_SESSION['val'] = $qui;
$_SESSION['value'] = ($_SESSION['value'] + $tst);
if($next <= $pages_count){
header('Location: quiz.php?id='.$cid.'&page=' .$next. '');
}
if($next > $pages_count){
echo 'Result';
exit;}
}
if($records_count != 0){
$ar = $db->query("SELECT * FROM `questions` WHERE `cat`='".$cid."' order by `id` desc LIMIT $start,$end");
while($rowar = $ar->fetch_object()){
echo"
<form ation='' method='POST'>
<div>".$rowar->question."</div>";
$ans = $db->query("select * from `answer` where `question_id`='".$rowar->id."' order by `id` desc");
$rowans = $ans->fetch_object();
echo"
<div ><input class='rgt' type='radio' name='val' value='".$rowans->val1."'/><p>".$rowans->answ1."</p></div>
<div><input type='submit' name='next'value='Next'/></div>
</form>

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";
?>
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 .
my default load page is ok with next and prev results.. but for search results i can get only first page then blank for the next page. let say total search results row is 9, it display 3 pages with next link. but when i click the next link, it queries no result on the page 2. here is my code:
echo '<table><tr><td>';
echo '<form method="post" name="frmSearch" action="mypage.php>
Search by name
<input type="text" name="txtSearch">
<input type="submit" name="submit" value="Search">
</form>';
$per_page = 5;
$page = 1;
if (isset($_GET['page']))
{
$page = intval($_GET['page']);
if($page < 1) $page = 1;
}
$start_from = ($page - 1) * $per_page;
$Prev_Page = $page - 1;
$Next_Page = $page + 1;
if (!$_POST){
//$sql = "SELECT * FROM mytable LIMIT $start_from, $per_page";
//$totalr = mysql_query("SELECT COUNT(*) FROM mytable");
//$totalr = mysql_fetch_row($totalr);
//$totalr = $totalr[0];
//$total_pages = $totalr / $per_page;
//$total_pages = ceil($total_pages);
//$listresult = mysql_query($sql);
//$total = mysql_num_rows($listresult);
}
else {
if ($_POST['txtSearch']!="") {$cond1 = " name LIKE
'%".$_POST['txtSearch']."%' ";} else {$cond1 = 1; }
$sql = "SELECT * FROM mytable WHERE ".$cond1." LIMIT $start_from, $per_page";
$totalr = mysql_query("SELECT COUNT(*) FROM mytable WHERE name LIKE
'%".$_POST['txtSearch']."%' ");
$totalr = mysql_fetch_row($totalr);
$totalr = $totalr[0];
$total_pages = $totalr / $per_page;
$total_pages = ceil($total_pages);
$listresult = mysql_query($sql);
$total = mysql_num_rows($listresult);
}
if($total == 0){
echo "<center>No records found.</center>";
}
echo "<span style='float:right;margin-top:8px;'>[ <a href='new.php'>Add New</a>
]</span></td></tr>";
echo "<table>
<tr>
<th>ID</th>
<th>Name</th>
</tr>
";
while ($_POST = mysql_fetch_assoc($listresult)){
echo "<tr>";
echo "<td>" . $_POST['id'] . "</td>";
echo "<td>" . $_POST['name'] . "</td>";
echo "</tr>";
}
echo "</table>";
echo "</table>";
echo $totalr." result";
echo "<br>";
if ($Prev_Page) {
echo " <a href ='{$_SERVER['PHP_SELF']}?page=$Prev_Page'><< Prev</a> ";
}
if ($totalr > $per_page) {
for($i = 1; $i <= $total_pages; ++$i)
{
echo "<a href='{$_SERVER['PHP_SELF']}?page=$i'>$i</a> | ";
}
}
if ($page!=$total_pages) {
echo " <a href='{$_SERVER['PHP_SELF']}?page=$Next_Page'>Next >></a> ";
}
maybe you need to use SELECT COUNT(*) FROM mytable WHERE name LIKE '%$search%' ... remember to escape the $_POST['txtSearch']
I have used this code before with no issues but... now I can't seem to load the page request when pressing Previous/Next Navigation if you can see where I went wrong be a help.
<?php
include 'config.php';
$db = mysql_connect($host, $username, $password);
mysql_select_db($db_name,$db);
$sql = "SELECT u_id FROM users";
$query = mysql_query($sql,$db);
$total_results = mysql_num_rows($query);
$limit = "5"; //limit of archived results per page.
$total_pages = ceil($total_results / $limit); //total number of pages
if (empty($page))
{
$page = "1"; //default page if none is selected
}
$offset = ($page - 1) * $limit; //starting number for displaying results out of DB
$query = "SELECT * FROM users ORDER BY u_id LIMIT $offset, $limit";
$result = mysql_query($query);
//This is the start of the normal results...
while ($row = mysql_fetch_array($result))
{
?>
<HR>
Username : <B><?echo $row['uname'] ?></B><BR>
user Message: <?echo $row['umess'] ?>
<BR>
<?
}
mysql_close();
// This is the Previous/Next Navigation stuff having issue with
echo "<font face=Verdana size=1>";
echo "Pages:($total_pages) "; // total pages
if ($page != 1)
{
echo "<a href=?&page=1><< First</a> "; // First Page Link
$prevpage = $page - 1;
echo " <a href=?page=$prevpage><<</a> "; // Previous Page Link
}
if ($page == $total_pages)
{
$to = $total_pages;
}
elseif ($page == $total_pages-1)
{
$to = $page+1;
}
elseif ($page == $total_pages-2)
{
$to = $page+2;
}
else
{
$to = $page+3;
}
if ($page == 1 || $page == 2 || $page == 3)
{
$from = 1;
}
else
{
$from = $page-3;
}
for ($i = $from; $i <= $to; $i++)
{
if ($i == $total_results) $to=$total_results;
if ($i != $page)
{
echo "<a href=?showold=yes&page=$i>$i</a>";
}
else
{
echo "<b><font face=Verdana size=2>[$i]</font></b>";
}
if ($i != $total_pages)
echo " ";
}
if ($page != $total_pages)
{
$nextpage = $page + 1;
echo " <a href=?page=$nextpage>>></a> "; // Next Page Link
echo " <a href=?page=$total_pages>Last >></a>"; // Last Page Link
}
echo "</font>";
?>
After a test run you can see 1st page request is fine untill you click next or a page number it keeps going back to 1st page.
Instead of
if (empty($page))
{
$page = "1"; //default page if none is selected
}
Try :
if (isset($_GET['page']))
{
$page = $_GET['page'];
}
else
{
$page = 1;
}
