I need some help, I want to make an next / previous page but I have some problems...
This is the PHP Code, how I try to make it. The problem is that it doesn't show 3 data on the first page and on the next page it puts the same data again an not the other one.
Code:
$statement = $connect->prepare("SELECT COUNT(*) AS anzahl FROM `accounts`");
$statement->execute();
$row = $statement->fetch();
$max_data = $row['anzahl'];
$page = 1;
if(isset($_GET['page'])) {
$page = intval($_GET['page']);
}
$max_info = 3;
$start = ($page - 1) * $max_info;
$number_page = ceil($max_data / floatval($max_info));
for($a = 1; $a <= $anzahl_seiten; $a++) {
if($page == $a){
echo " <b>$a</b> ";
}
else {
echo " <a href='acp.php?page=list_all_player&seite=$a'>$a</a> ";
}
}

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 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; $i++)
//Here you can loop through the numbers within adjacents of the current page
I have a large database which can yield thousands of results and I need to limit the amount of pagination links of say 9 links, with previous 4 pages on one side then the current page then the 4 next pages.
for example: 14|15|16|17|18|19|20|21|22
anyone know how I could achieve this? Thanks
if (isset($_GET["page"]))
{
$page = $_GET["page"];
}
else
{
$page=1;
};
$start_from = ($page-1) * 10;
$message = "SELECT * FROM document WHERE email='$_SESSION[email]' ORDER BY id DESC LIMIT $start_from , 10";
// echo results
// make page links for results
$sql = "SELECT id FROM document WHERE email = '$_SESSION[email]'";
$rs_result = $db->query($sql);
$total_records = $rs_result->num_rows;
$total_pages = ceil($total_records / 10);
if($rs_result->num_rows >10) {
$page = "<p class = 'page'>";
for ($i=1; $i<=$total_pages; $i++)
{
$page .="<a href='results.html?page=".$i."'>".$i."</a> ";
}
$page .="</p>";
echo $page;
}
Just use basic math to calculate the start and end pages for use in your loop:
$page_range_offset = 4;
$page_start = $page - $page_range_offset;
if ($page_start < 1) {
$page_start = 1;
}
$page_end = $page + $page_range_offset;
if ($page_end > $total_pages) {
$page_end = $total_pages;
}
for ($i=$page_start; $i<=$page_end; $i++) {
$page .="<a href='results.html?page=".$i."'>".$i."</a> ";
}
I have the following mysql query and I have added pagination from here:
http://www.tonymarston.net/php-mysql/pagination.html
$DBQuery3 = mysqli_query($dblink, "SELECT * FROM images WHERE project_id = '$FormProjectID'");
if (mysqli_num_rows($DBQuery3) < 1) {
$ProjectContent = '
<p>This project is empty. Upload some files to get started.</p>
';
} else {
//if no page number is set, start at page 1
if (isset($_GET['pageno'])) {
$pageno = $_GET['pageno'];
} else {
$pageno = 1;
}
//This code will count how many rows will satisfy the current query.
$DBQuery3b = mysqli_query($dblink, "SELECT count(*) FROM images WHERE project_id = '$FormProjectID'");
$query_data = mysqli_fetch_row($dblink, $DBQuery3b);
$numrows = $query_data[0];
//This code uses the values in $rows_per_page and $numrows in order to identify the number of the last page.
$rows_per_page = 2;
$lastpage = ceil($numrows/$rows_per_page);
//This code checks that the value of $pageno is an integer between 1 and $lastpage.
$pageno = (int)$pageno;
if ($pageno > $lastpage) {
$pageno = $lastpage;
}
if ($pageno < 1) {
$pageno = 1;
}
//This code will construct the LIMIT clause for the sql SELECT statement.
$limit = 'LIMIT ' .($pageno - 1) * $rows_per_page .',' .$rows_per_page;
$DBQuery3c = "SELECT * FROM images WHERE project_id = $FormProjectID $limit";
$DBQuery3d = mysqli_query($dblink, $DBQuery3c);
//set this variable to empty and so we can latwe loop and keep adding images to it
$ProjectContent ='';
while($row = mysqli_fetch_array($DBQuery3d)) {
$DBImageID = $row['image_id'];
$DBProjectID = $row['project_id'];
$DBImageName = $row['image_name'];
$DBImageDescription = $row['image_description'];
$DBDateCreated = $row['date_created'];
$DBLinkToFile = $row['link_to_file'];
$DBLinkToThumb = $row['link_to_thumbnail'];
$DBGivenName = $row['given_name'];
//if the image was given a name by the user, display it
//otherwise display the generated name
if (strlen($DBGivenName) > 1) {
$FileName = $DBGivenName;
} else {
$FileName = $DBImageName;
}
$ProjectContent .= '
<img src="uploads/'.$DBLinkToThumb.'" width="150px" height="150px" alt="'.$FileName.'" title="'.$FileName.'"/>
';
//Finally we must construct the hyperlinks which will allow the user to select other pages. We will start with the links for any previous pages.
if ($pageno == 1) {
$FirstPrev = " FIRST PREV ";
} else {
$First = " <a href='{$_SERVER['PHP_SELF']}?page=project&id=$FormProjectID&pageno=1'>FIRST</a> ";
$prevpage = $pageno-1;
$Prev = " <a href='{$_SERVER['PHP_SELF']}?page=project&id=$FormProjectID&pageno=$prevpage'>PREV</a> ";
}
//Next we inform the user of his current position in the sequence of available pages.
$PageNumb = " ( Page $pageno of $lastpage ) ";
//This code will provide the links for any following pages.
if ($pageno == $lastpage) {
$NextLast = " NEXT LAST ";
} else {
$nextpage = $pageno+1;
$Next = " <a href='{$_SERVER['PHP_SELF']}?page=project&id=$FormProjectID&pageno=$nextpage'>NEXT</a> ";
$Last = " <a href='{$_SERVER['PHP_SELF']}?page=project&id=$FormProjectID&pageno=$lastpage'>LAST</a> ";
}
}
}
Then in my html I have:
<div id="projectview">
<?php echo $ProjectContent; ?>
<?php echo $FirstPrev; ?>
<?php echo $First; ?>
<?php echo $Prev; ?>
<?php echo $PageNumb; ?>
<?php echo $NextLast; ?>
<?php echo $Next; ?>
<?php echo $Last; ?>
<div class="clear-div"></div>
</div>
This is outputing for example in this case 2 images, but the pagination links look like this:
FIRST PREV ( Page 1 of 0 ) NEXT LAST
Clicking on the links is not cycling through any other images, it still shows the same 2 images.
I can't figure out what I have done wrong here. I don't understand why it says "1 of 0" when clearly there should be more results.
here is my paging code:
function getPagingQuery($sql, $itemPerPage = 10)
{
if (isset($_GET['page']) && (int)$_GET['page'] > 0) {
$page = (int)$_GET['page'];
} else {
$page = 1;
}
// start fetching from this row number
$offset = ($page - 1) * $itemPerPage;
return $sql . " LIMIT $offset, $itemPerPage";
}
function getPagingLink($sql, $itemPerPage = 10, $strGet ="")
{
$result = dbQuery($sql);
$pagingLink = '';
$totalResults = dbNumRows($result);
$totalPages = ceil($totalResults / $itemPerPage);
// how many link pages to show
$numLinks = 10;
// create the paging links only if we have more than one page of results
if ($totalPages > 1) {
$self = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'] ;
if (isset($_GET['page']) && (int)$_GET['page'] > 0) {
$pageNumber = (int)$_GET['page'];
} else {
$pageNumber = 1;
}
// print 'previous' link only if we're not
// on page one
if ($pageNumber > 1) {
$page = $pageNumber - 1;
if ($page > 1) {
$prev = " [Prev] ";
} else {
$prev = " [Prev] ";
}
$first = " [First] ";
} else {
$prev = ''; // we're on page one, don't show 'previous' link
$first = ''; // nor 'first page' link
}
// print 'next' link only if we're not
// on the last page
if ($pageNumber < $totalPages) {
$page = $pageNumber + 1;
$next = " [Next] ";
$last = " [Last] ";
} else {
$next = ''; // we're on the last page, don't show 'next' link
$last = ''; // nor 'last page' link
}
$start = $pageNumber - ($pageNumber % $numLinks) + 1;
$end = $start + $numLinks - 1;
$end = min($totalPages, $end);
$pagingLink = array();
for($page = $start; $page <= $end; $page++) {
if ($page == $pageNumber) {
$pagingLink[] = " $page "; // no need to create a link to current page
} else {
if ($page == 1) {
$pagingLink[] = " $page ";
} else {
$pagingLink[] = " $page ";
}
}
}
$pagingLink = implode(' | ', $pagingLink);
// return the page navigation link
$pagingLink = $first . $prev . $pagingLink . $next . $last;
}
return $pagingLink;
}
im calling it like:
$sql = "something";
$result = mysql_query(getPagingQuery($sql, $rowsPerPage));
$pagingLink = getPagingLink($sql, $rowsPerPage, $url);
now if my url is like
http://xyz/abc/list.php its working fine.
but when my url is like
http://xyz/abc/list.php?action=def
after i click on page 2 the url changes like http://xyz/abc/list.php?page2&
'action=def' part is gone so the result changes.
if i use to pass the value in $strGet as $_SERVER['QUERY_STRING']
the 1st time it is ok like http://xyz/abc/list.php?page2&action=def
but from the 2nd time onwards it gives like http://xyz/abc/list.php?page3&page2&action=def
so not getting the desired result.
whereas i want it to be like http://xyz/abc/list.php?page3&action=def
plz help.. thanxx in advance
So I consider you use $_GET['page'] ^^
$_GET['page']=$page;
$url = 'http://xyz/abc/list.php?';
foreach($_GET as $key=>$param) {
$url.=$key.'='.$param.'&';
}
use http_build_query() instead of $_SERVER['QUERY_STRING']
What i would do is before setting $page = url code. i would first echo $page before and after setting it. so that i can see exactly what the values are. And i would print echo statements before and after everytime i set $page with the url to make sure it is correct. and if in any place you can see that its not the desired output because you can see that from the echo statements then you can make the right changes to make sure the $page variable is set properly.
what i would do then to set it properly is clear the $page variable and make sure that the $page variable is then set freshly with the url.
also when setting the url make sure that the $strGet variable is also echoed out first to make sure that it is the right value that you want to set. and then set the url to the $page variable.
By doing this simple debugging you are making sure all the values are correct first and you know it is before setting them.
give it a go
let me know what happens
