The code which I use to show Links of 10 pages per page in pagination is:
$start = ( floor($page/10) * 10 ) + 1;
for( $i = $start; $i < $totalPages; $i++){
if( $i >= ($start + 10)){
break;
}
else{
}
echo ' ' . $i . ' ';
}
I want to hide the current page link such that if I was on Page 7 it will hide the link 7. can anybody help?
Echo only if the page is not equal to the current page.
if ($page != $i) echo ' ' . $i . ' ';
You need to get the current page and then just use a simple condition. Something like:
$currentPage = $_GET["page"];
$start = ( floor($page/10) * 10 ) + 1;
for( $i = $start; $i < $totalPages; $i++){
if( $i >= ($start + 10)){
break;
}
else {
if ($i!=$currentPage) echo ' ' . $i . ' ';
}
}
Also, I moved echo inside the else {} part because I believe it should be there.

I tried to make a PHP pagination like this:
$count = $this->dataBaseFunctions->countItems();
$resultperPage = 10;
$offset = 0;
$adjacents = 3;
$totalPages = ceil(intval($count) / $resultperPage);
if (isset($_GET['offset'])) {
$offset = trim($_GET['offset']);
}
$j = $adjacents;
while ($j > 0) {
if (($offset / 10) - 1 > 0) {
echo '' . ($offset - 10 - ($j * 10)) . ' ';
}
$j--;
}
/*for ($j = $adjacents; $j > 0; $j--) {
echo '' . ($offset - 10 - ($j * 10)) . ' ';
}*/
echo '[' . ($offset - 10) . '] ';
for ($j = 1; $j < ($adjacents + 1); $j++) {
echo '' . ($offset - 10 + ($j * 10)) . ' ';
}
The result should look like this (Brackets = current clicket page):
[0] 1 2 3
When I click "3" it should look like this (works so far):
0 1 2 [3] 4 5 6
But when I click "1" the result looks like this:
-2 -1 0 [1] 2 3 4
The "0" is not a problem, I just 'echoed' it for debugging.
I know that I dont set the right conditions for not showing pages below 1 but I dont get it how to make it right. Seems like I have tomatoes on my eyes... The echo is just for testing - later I save the whole pagination links into a variable to assign it to the bottom of the page. Its a bit of debugging code you see here but it shows what I try to do. Please let me know if I can improve the question or if there are missing informations like: "why you do ($offset / 10) -1 > 0" ;-)
Later I need to do same stuff in JS but I think I can manage that, when I know what I did wrong in the PHP version.
*Maybe it's a bad Idea what I try to do there?
This one should do the trick:
Now including the $adjacents
$count = $this->dataBaseFunctions->countItems();
$resultperPage = 10;
$offset = 0;
$adjacents = 3;
$totalPages = ceil(intval($count) / $resultperPage);
if (isset($_GET['offset'])) {
$offset = trim($_GET['offset']);
}
$start = ($offset-$adjacents) > 0 ? ($offset-$adjacents) : 0;
$end = ($offset+$adjacents) < $totalPages ? ($offset+$adjacents) : $totalPages;
$pager = "";
for ($i = 0; $i < $totalPages; $i++) {
if ($i >= $start && $i <= $end) {
$pager .= $offset != $i ? '' . $i . ' ' : "[$i] ";
}
}
echo $pager;
I was able to get my pagination script working, and everything works fine except when you go to PAGE 2, you can see a PAGE 0, which if you click on it give you nothing.
I need to fix my current code so that the application does not show a PAGE 0.
Here is the necessary code:
<?php
$total_records = countRecords(); // self explanatory function called here
$total_pages = ceil($total_records / $rec_limit);
$adjacents = 2;
$previousPage = $page - 1;
$nextPage = $page + 1;
$querystring = "";
$start = ($page < $adjacents ? 1 : $page - $adjacents);
$beginning = 1;
$end = ($page > $total_pages - $adjacents ? $total_pages : $page + $adjacents);
foreach($_GET as $key => $value)
{
if($key != "page") $querystring .= "$key=$value&";
}
echo
'<div class="row-fluid">
<div class="span2">'.countRecords()." total records" .'</div>
<div class="container pagination-small">
<ul style="margin: 3px;" class="pager">';
echo #"<li>First</li>";
if ($left_rec < $rec_limit)
{
$last = $page - 1;
echo #"<li><a href=\"$targetpage?page=$previousPage&$querystring\">
Previous</a></li>";
for($i= $start; $i <= $end; $i++)
{
echo #"<li " . ((($page)==$i)? "class=\"active\"" : "") . ">
$i</li>";
}
}
else if($page == 0)
{
for($i= $start; $i <= $end; $i++)
{
echo #"<li " . ((($page)==$i)? "class=\"active\"" : "") . ">
$i</li>";
}
echo #"<li>Next</li>";
}
else if ($page > 0)
{
$last = $page - 2;
echo #"<li><a href=\"$targetpage?page=$previousPage&$querystring\">
Previous</a></li>";
for($i= $start; $i <= $end; $i++)
{
echo #"<li " . ((($page)==$i)? "class=\"active\"" : "") . ">
$i</li>";
}
echo #"<li>Next<li>";
}
echo #"<li>Last</li>";
echo '<ul></div></div>';
I tried to keep the code as short as possible. If there are any errors, just note it's only a typo as I typed it here. The code works, with exception to my problem.
So with that all said, can anyone tell me how to remove PAGE 0 from the pagination? I have done some research, but I have been unsuccessful applying it to my code. So I'm hoping someone can take a look at my code and tell me how I can alter it to make this work.
I appreciate the help.
Thank you in advance.
Logic flaw:
$start = ($page < $adjacents ? 1 : $page - $adjacents);
If you're on Page 1, you'll get
$start = (1 < 2 ? 1 : 1 - 2);
$start = -1; // page negative one? huh?
Then this loop is pointless:
foreach($_GET as $key => $value) { ... }
Why not just
unset($_GET['page']);
$q = http_build_query($_GET);
I was able to create a working pagination system for my application. But the problem I am having is when a user does a search, it can/will display over 100 pages in the pagination.
I am trying to figure out how to show only like 5 on each side of the current page. I would like to create a FIRST page button, and a LAST page button, but I'll deal with that later.
So here is the first part of code that counts the records in the database table:
<?php
function countRecords()
{
// The application takes a lot of user input, which then builds a query here.
// The user input goes into a session variable called $_SESSION['where']
// I'll start with the actual query code
$sql = "SELECT COUNT(DISTINCT CONTAINER_NUMBER) AS TOTAL
FROM 'contTable'" . " WHERE (" . $_SESSION['where'] . ");";
$sqlres = #mysql_query($sql) or die();
$row = mysql_fetch_row($sqlres);
$return $row[0];
}
So code above gets the count from the table depending on the search criteria.
Here is the next piece of code that prints the grid. I'll keep it as short as possible:
function displayrecords()
{
$rec_limit = 100;
$targetpage = "containers.php";
if(isset($_GET['page']))
{
$page = $_GET['page'];
$offset = $rec_limit * ($page - 1);
}
else
{
$page = 1;
$offset = $rec_limit * ($page - 1);
}
$left_rec = countRecords() - ($page * $rec_limit);
$select = "";
$_SESSION['where'] = "";
// user input variables are here that build a variable called $_SESSION['where']
// I'll skip the code down to the query
if ($_SESSION['where'] != "") $select = "SELECT * FROM 'contTable'" . " WHERE
(" . $_SESSION['where'] . ") GROUP BY container, bol LIMIT " . $offset . ",
" . $rec_limit . ";";
}
Please excuse any typos or missing brackets and whatnot. Just know the above code works.
Now here is the code for the rest of the pagination:
$total_records = countRecords();
$total_pages = ceil($total_records / $rec_limit);
$adjacents = 5; // I just added this variable. I don't know what to do with it
$previousPage = $page - 1;
$nextPage = $page + 1;
$querystring = "";
foreach ($_GET as $key => $value)
{
if ($key != "page") $querystring .= "$key=$value&";
}
echo '<ul style="border: 0px solid red; margin: 3px;" class="pager">';
if ($left_rec < $rec_limit)
{
$last = $page - 2;
echo #"<li><a href=\"$targetpage?page=$previousPage&$querystring\">
Previous</a></li>";
for($i = 1; $i <= $total_pages; $i++)
{
echo #"<li " . ((($page+1)==$i)? "class=\"active\"" : "") . ">
$i</li>";
}
}
else if ($page == 0)
{
for($i = 1; $i <= $total_pages; $i++)
{
echo #"<li " . ((($page+1)==$i)? "class=\"active\"" : "") . ">
$i</li>";
}
echo #"<li>Next</li>";
}
else if ($page > 0)
{
$last = $page - 2;
echo #"<li><a href=\"$targetpage?page=$previousPage&$querystring\">
Previous</a></li> ";
for($i = 1; $i <= $total_pages; $i++)
{
echo #"<li " . ((($page+1)==$i)? "class=\"active\"" : "") . ">
$i</li>";
}
echo #"<li>Next</li>";
}
echo '</ul>';
}
So, with all of the code above, I can display a grid, and display the pages at the bottom of the application. But I don't want to show all 100 pages, only 5 on each side of the current page. I know I need to utilize the variable called $adjacents and plug it in to the paging portion of the code. But I'm not exactly sure how to do it.
I hope I am being clear on my request.
Please help.
Instead of looping through all of the pages:
for($i = 1; $i <= $total_pages; $i++)
Try doing something like this:
$start = ($page < $adjacents ? 1 : $page - $adjacents);
$end = ($page > $total_pages - $adjacents ? $total_pages : $page + $adjacents);
for($i= $start; $i <= $end; $i++)
//Here you can loop through the numbers within adjacents of the current page
I have two tiny little problems;
1 . I want to add a previous / next button into this code
2 . I want it to only show like max 10 links between previous and next. So if i have 50 numbers/links it will only show 10 of them and not 50 links on the page.
I have searched on the clo
The code works, only need that two options in it.
Can someone help me out? Thank you !
<?php
include 'includes/connection.php';
$per_page = 8;
$pages_query = mysql_query("SELECT COUNT(`id`) FROM `products`");
$pages = ceil(mysql_result($pages_query, 0) / $per_page);
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;
$query = mysql_query("SELECT `name` FROM `products` LIMIT $start, $per_page");
while ($query_row = mysql_fetch_assoc($query)) {
echo '<p>', $query_row['name'] ,'</p>';
}
if ($pages >= 1 && $page <= $pages) {
for ($x=1; $x<=$pages; $x++) {
//echo $x, ' ';
echo ($x == $page) ? '<strong>'.$x.'</strong> ' : ''.$x.' ';
}
}else{
header("location:index.php?page=1");
}
?>
First of all, you should, just for good practice, put an "exit;" after the header() call at the end. It doesn't make a difference in this particular script, but keep in mind that any code following a header("Location: ...") call WILL be executed before redirection.
Now to your question, try this (UPDATE: This code has been tested and works.)
<?php
include 'includes/connection.php';
$per_page = 8;
$pages_query = mysql_query("SELECT COUNT(`id`) FROM `products`");
$pages = ceil(mysql_result($pages_query, 0) / $per_page);
$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;
$query = mysql_query("SELECT `name` FROM `products` LIMIT $start, $per_page");
while ($query_row = mysql_fetch_assoc($query))
{
echo '<p>' . $query_row['name'] . '</p>';
}
// If the requested page is less than 1 or more than the total number of pages
// redirect to the first page
if($pages < 1 || $page > $pages)
{
header('Location: ?page=1');
// end execution of the rest of this script
// it will restart execution after redirection
exit;
}
// If more than one page, show pagination links
if($pages > 1)
{
$html = array();
$html[] = '<strong>';
// if you're on a page greater than 1, show a previous link
$html[] = (($page > 1) ? 'Previous ' : '');
// First page link
$pageFirst = '1';
$html[] = (($page == 1) ? "</strong>{$pageFirst}<strong>" : $pageFirst);
if ($pages > 6)
{
$start_cnt = min(max(1, $page - (6 - 1)), $pages - 6);
$end_cnt = max(min($pages, $page + 4), 8);
$html[] = ($start_cnt > 1) ? '...' : ' ';
for ($i = $start_cnt + 1; $i < $end_cnt; $i++)
{
$html[] = ($i == $page) ? '</strong>' . $i . '<strong>' : '' . $i . '';
if ($i < $end_cnt - 1)
{
$html[] = ' ';
}
}
$html []= ($end_cnt < $pages) ? '...' : ' ';
}
else
{
$html[] = ' ';
for ($i = 2; $i < $pages; $i++)
{
$html[] = ($i == $page) ? '</strong>' . $i . '<strong>' : '' . $i . '';
if ($i < $pages)
{
$html[] = ' ';
}
}
}
// last page link
$pageLast = '' . $pages . '';
$html[] = (($page == $pages) ? "</strong>{$pageLast}<strong>" : $pageLast);
// Show next page link if you're on a page less than the total number of pages
$html[] = ($page < $pages) ? ' Next' : '';
// If you're not on the last page, show a next link
$html[] = '</strong>';
}
else
{
// show page number 1, no link.
$html[] = '<strong>1</strong>';
}
echo implode('', $html);
Also note that the final ?> is not required in PHP files that do not have HTML code following the PHP code, so I left it off.

I asked a similar question like this yesterday but after waiting for ever I figured out part of the problem but now I'm stuck again I'm trying to display ... when the search results are to long because my pagination links will keep on displaying and will not stop until every link is displayed on the page.
For example I'm trying to achieve the following in the example below. Can some one help me fix my code so I can update my site. Thanks
This is what I want to be able to do.
First Previous 1 2 ... 5 6 7 8 9 10 11 12 13 ... 199 200 Next Last
Here is my pagination code that displays the links.
$display = 20;
if (isset($_GET['p']) && is_numeric($_GET['p'])) {
$pages = $_GET['p'];
} else {
$q = "SELECT COUNT(id) FROM comments WHERE user_id=3";
$r = mysqli_query ($mysqli, $q) or trigger_error("Query: $q\n<br />MySQL Error: " . mysqli_error($mysqli));
$row = mysqli_fetch_array ($r, MYSQLI_NUM);
$records = $row[0];
if ($records > $display) {
$pages = ceil ($records/$display);
} else {
$pages = 1;
}
}
if (isset($_GET['s']) && is_numeric($_GET['s'])) {
$start = $_GET['s'];
} else {
$start = 0;
}
//content goes here
if ($pages > 1) {
echo '<br /><p>';
$current_page = ($start/$display) + 1;
if ($current_page != 1) {
echo 'First';
}
if ($current_page != 1) {
echo 'Previous ';
}
for ($i = 1; $i <= $pages; $i++) {
if ($i != $current_page) {
echo '' . $i . ' ';
} else {
echo '<span>' . $i . '</span> ';
}
}
if ($current_page != $pages) {
echo 'Next';
}
if ($current_page != $pages) {
echo 'Last';
}
echo '</p>';
}
Instead of the loop just use something like this:
if($current_page > 8 && $pages > 11) {
echo '1 ';
echo '2 ';
echo '...';
}
for ($i = max(1, $current_page - 4); $i < min($current_page + 4, $pages); $i ++) {
echo '' . $i . ' ';
}
if ($current_page < $pages - 8 && $pages > 11) {
echo '...';
echo '' . ($pages - 1) . ' ';
echo '' . $pages . ' ';
}
