I'm having a problem with my PHP pagination for a project.
It almost works but it doesn't seem to display the numbers correctly.
I want only 6 more page numbers to display after the selected and one before;
(also if you are on page one display 7 after)
For example:
If on Page 1: 1/2/3/4/5/6/7/8
If on Page 2: 1/2/3/4/5/6/7/8
If on Page 5: 4/5/6/7/8/9/10/11
If on Page 10: 9/10/11/12/13/14/15/16
This is my code so far...
if($page == ceil($NumOfPages) && $page != 1){
for($i = 1; $i <= ceil($NumOfPages)-1; $i++){
if($i > 0){
echo "{$i}";
}
}
}
if ($page == ceil($NumOfPages) ) {
$startPage = $page;
}else{
$startPage = 1;
}
for ($i = $startPage; $i <= $page+6; $i++){
if ($i <= ceil($NumOfPages)){
if($i == $page) {
echo "<a href='/page/$i/' title='View movies page $i' id='pagelisel'>$i</a> ";
}else{
echo "<a href='/page/$i/' title='View movies page $i' id='pageli'>$i</a> ";
}
}
}
Any help would be greatly appreciated,
Thanks!
I assumed that (partly for myself... ;) ):
$page is the selected page
$startPage is the first page number you want to show
$numPages is already ceil-ed
First you need to find $startPage. Depending whether $page is the first one (ie has the value one 1, another assumption) or not. Your check is slightly off, as it check if it is equal to the last page.
if($page == 1) {
$startPage = 1;
} else {
$startPage = $page - 1;
}
Then you need to find out the last page number you want to print ($lastPage). So check if $startPage is near the end and set ~$lastPage` accordingly:
if($startPage + 7 > $numPages) {
$endPage = $numPages;
} else {
$endPage = $startPage + 7;
}
Finally, use you for-loop which seem ok, but loop from $startPage to $endPage.
Here's an alternative approach that should work for you as well:
$pageCurrent = $page;
$pagePrevious = $pageCurrent-1;
$pageClass = '';
$pageStart = 1;
$pageEnd = $pageCurrent+6;
$pageMax = ceil($NumOfPages);
if($pageCurrent==1){
echo "1";
}else{
echo "$pagePrevious";
}
for($i = $pageStart; $i <= $pageEnd; $i++){
if($i <= $pageEnd){
if($i == 1 && $pageCurrent != 1){
$pageClass = 'selected';
}else{
$pageClass = '';
}
echo "$i";
}
}

I have 100+ records in my database so i am using pagination but it prints page number for every page like 1,2,3,5 and so on how to limit the number shown in pagination.
Here is my code:
$row_offer2=mysqli_num_rows($sql_result2);
$total=ceil($row_offer2/$num_rec);
echo "<div class='col-md-12' style='margin:0 auto;text-align:center;'><ul
class='pagination '>";
echo "<li id='1' class='pag'>".'|<'."</li>"; // Goto 1st page
for ($i=1; $i<=$total; $i++) {
echo "<li id=".$i." class='pag'>".$i."</a></li> ";
};
echo "<li id=".$total." class='pag'>".'>|'."</a></li> "; // Goto last page
echo "</ul></div>";
?>
Show pagination for current page +- x pages (x should be something like 2-3) and show the first and last page.
$currentPage = 6;
function getPages($cp, $max, $offset) {
$pages = [];
$pages[] = 1;
$min = ($cp - $offset) > 1 ? $cp - $offset : 1;
$lim = ($cp + $offset) < $max ? $cp + $offset : $max;
for ($i = $min; $i < $lim; $i++) {
$pages[] = $i;
}
$pages[] = $max;
return array_unique($pages);
}
var_dump(getPages($currentPage, 20, 3));
then you can simply loop with foreach through array you receive from this function and display your LIs
Control your loop with number you want to show. If you want to show 3 pages in pagination just do this.
for ($i=1; $i<=3; $i++) {
echo "<li id=".$i." class='pag'>".$i."</a></li> ";
};
I have the following code:
$max = 4;
$page = isset($_GET['page']) ? ($_GET['page']) : '1';
$init = $page - 1;
$init= $max * $init;
$strCount = "SELECT COUNT(*) AS 'total_mytable' FROM mytable";
$varstrCount = $crud->viewdatas($strCount);
$total = 0;
if(count($varstrCount)){
foreach ($varstrCount as $row) {
$total = $row["total_mytable"];
}
}
$result = "SELECT * FROM mytable ORDER BY id_mytable LIMIT $init,$max";
$varresult = $crud->viewdatas($result);
content of page:
<?php
if(count($varresult)){
foreach ($varresult as $res) {
?>
<h5><?php echo $res['title'] ?></h5>
<?php
}
}
?>
<?php
$max_links = 10;
$previous = $page - 1;
$next = $page + 1;
$pgs = ceil($total / $max);
if($pgs > 1 ){
if($previous > 0){
echo "<li><a href='".BASE_URL."/category/$previous' aria-label='Previous'><span aria-hidden='true'>«</span></a></li>";
} else{
}
for($i=$page-$max_links; $i <= $pgs-1; $i++) {
if ($i <= 0){
}else{
if($i != $page{
if($i == $pgs){ //if end insert 3 dots
echo "<li><a href='".BASE_URL."/category/".($i)."'>".$i."</a></li> ...";
}else{
echo "<li><a href='".BASE_URL."/category/".($i)."'>".$i."</a></li>";
}
} else{
if($i == $pgs){ //if end insert 3 dots
echo "<li>".$i."</li> ...";
}else{
echo "<li>".$i."</li>";
}
}
}
}
if($next <= $pgs){
echo "<li><a href='".BASE_URL."/category/$next' aria-label='Next'><span aria-hidden='true'>»</span></a></li>";
}else{
}
}
?>
The result:
And I not understand the reason for the active number stay right off the paging menu
In the code I defined max-links for 10, but no show number 5 and if I define max links for 3 changes nothing , displays the same result as the image.
Thanks for any help
echo "<li>".$i."</li>";
on the above line add up a href, seems like you have css formatting for li>a because of which you are not getting the required formatting on only li. so for getting better formatting for all paging links current, prev, next. you need to add up a tags.
echo "<li><a>".$i."</a></li>"; //in your else part
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 have page with a URL like this:
http://***.com/profile/username#profile_favs
With my pagination it looks like this:
http://***.com/profile/username?s=0&p=1#profile_favs
The last example doesn't work.
Basically my pagination-function looks like this:
function Pagination($pages, $start, $display, $link_url="", $anchor="") {
echo '<div id="pagination">';
$current_page = ($start / $display) + 1;
$paginator_num = 5;
$pages_display = 10;
if ($current_page > $pages - $paginator_num) {
$paginator_num = $pages_display - ($pages - $current_page);
} elseif ($current_page < $paginator_num + 1) {
$paginator_num = $pages_display - $current_page;
} else {
$paginator_num = 5;
}
$min = max($current_page - $paginator_num, 1);
$max = min($current_page + $paginator_num, $pages);
for ($i = $min; $i <= $max; $i++) {
if ($i != $current_page) {
echo '<div class="pagination_link">';
echo '' . $i . '';
echo '</div>';
} else {
echo '<div id="pagination_active" class="pagination_link">';
echo $i . ' ';
echo '</div>';
}
}
echo '</div>';
}
And this is the part that calculates the pages (this part gets included right before my pagination-function):
<?php
$display = $display_num;
if (isset($_GET['p']) && is_numeric ($_GET['p'])) {
$pages = $_GET['p'];
} else {
$total_results = $qr_num;
if ($total_results > $display) {
$pages = ceil ($total_results / $display);
} else {
$pages = 1;
}
}
if (isset($_GET['s']) && is_numeric ($_GET['s'])) {
$start = $_GET['s'];
} else {
$start = 0;
}
?>
Now my question is: Is there any workaround possible to get that pagination working with a URL mentioned above:
http://***.com/profile/username?s=0&p=1#profile_favs
Actually I'd prefer a solution without GET-parameters.
You could use an AJAX call with the XMPHttpRequest Object to fetch it without the get parameters.
Another thing you could do (if you are using Apache) is to look at mod_rewrite for urls.
Hope that helps :)
I want to limit the number of pages displayed on my pagination php script below. This was a script made a few years back for me, and although I have read through similar problems on here, their coding is very different.
Any help with this would be really appreciated.
Here is my current script:
<?php
if ($max_pages>1) {
echo "<br>";
if ($page>0) {
echo 'Previous';
}
for ($x=0;$x<$max_pages;$x++) {
if ($page<>$x) {
echo ''.($x+1).'';
}
else {
echo '<span class="pagination">'.($x+1).'</span>';
}
}
if (($page+1<>$max_pages)) {
echo 'Next';
}
}?>
Your current script cycles $x between 0 and $max_pages.
What you can do is first replace them with $from_page and $to_page:
$from_page = 0;
$to_page = $max_pages;
...
for ($x=$from_page; $x < $to_page; $x++)
at which point the script will work just as before.
Now if you want to only display from $N pages before to $N pages after $page,
$N = 5; // display 5+5+1 = 11 pages
$from_page = $page - $N; if ($from_page < 0) $from_page = 0;
$to_page = $from_page + 2*$N+1; if ($to_page > $max_pages) $to_page = $max_pages;
$from_page = $to_page - 2*$N-1; if ($from_page < 0) $from_page = 0;
Not the most elegant way perhaps, but it will try to fit an 11-page area centered on the current page. You may want to also display a link to pages 0 and $max_pages-1.
MRE version
<?php
if ($max_pages>1)
{
$N = 5; // display 5+5+1 = 11 pages
$to_page = min($max_pages, max(0, $page - $N) + 2*$N+1);
$from_page = max($to_page - 2*$N-1, 0);
echo "<br>";
if ($page > 0)
{
echo 'Previous';
}
for ($x=$from_page; $x < $to_page; $x++) {
if ($page != $x) {
echo ''.($x+1).'';
}
else {
echo '<span class="pagination">'.($x+1).'</span>';
}
}
if (($page+1<>$max_pages)) {
echo 'Next';
}
