I'm trying to code pagination and it should show this:
<<1...11>>
but instead it shows this:
<<-5...11>>
This happens if the content less than 11 pages.
this is my code
<?php if($page != 1): ?>
<a href="?page=<?php echo $page-1; ?>&srch-term=<?php echo #$_GET['srch-term']; ?>&tag=<?php echo #$_GET['tag']; ?>&color=<?php echo #$_GET['color']; ?>" aria-label="Previous">
<span aria-hidden="true">«</span>
</a>
<?php else: ?>
<span aria-hidden="true">«</span>
<?php endif; ?>
</li>
<?php
$limitPage = 5;
$fromPage = ($page - $limitPage) <= 0 ? 1:$page - $limitPage;
$endPage = ($page + $limitPage) >= $count? $count:$page+$limitPage;
if($page <= ($limitPage)) $endPage = ($limitPage*2) + 1;
if(($page - $limitPage) > ($count - ($limitPage*2))) $fromPage = $count - ($limitPage*2);
?>
<?php for($i=$fromPage;$i<=$endPage;$i++): ?>
<li class="<?php echo ($page == $i)? 'active':''; ?>"><?php echo $i; ?></li>
<?php endfor; ?>
<li class="<?php echo ($page == $count)? 'disabled':''; ?>">
<?php if($page != $count): ?>
<a href="?page=<?php echo $page+1; ?>&srch-term=<?php echo #$_GET['srch-term']; ?>&tag=<?php echo #$_GET['tag']; ?>&color=<?php echo #$_GET['color']; ?>" aria-label="Next">
<span aria-hidden="true">»</span>
</a>
<?php else: ?>
<span aria-hidden="true">»</span>
<?php endif; ?>
Looks like this is the line that is not working the way you expect.
if(($page - $limitPage) > ($count - ($limitPage*2))) $fromPage = $count - ($limitPage*2);
Here is a php sandbox link with some debugging code that should help you out. http://sandbox.onlinephpfunctions.com/code/df2faac69d217ce8e5bea86b63325b8dd4c49600
$limitPage = 5;
$page = 1;
$count = 5;
$fromPage = ($page - $limitPage) <= 0 ? 1:$page - $limitPage;
$endPage = ($page + $limitPage) >= $count? $count:$page+$limitPage;
echo $fromPage . ' ' . $endPage. "\n";
if($page <= ($limitPage)) $endPage = ($limitPage*2) + 1;
echo $fromPage . ' ' . $endPage. "\n";
if(($page - $limitPage) > ($count - ($limitPage*2))) $fromPage = $count - ($limitPage*2);
echo $fromPage . ' ' . $endPage;

I want to make a pagination for search results. I can see the results in first page when I use the search box but I can't see the other results in other pages. What am I doing wrong?
I would be really glad if you could help me
Here' my search page codes.

}
$sql_query2 = "SELECT * FROM posts ";

The code I have works absolutely perfectly:
<?
$maxresults = 10;
$total = $row[total];
$pagecount = $total / $maxresults;
if (!isset($_GET['page'])) { $_GET['page'] = '1'; }
$startcount = (($_GET['page'] - 1) * $maxresults + 1);
$stopcount = $startcount + ($maxresults - 1);
$lastTime = null;
$i='0';
$sc = $startcount;
$stmt=$db->prepare("// SELECT STATEMENT");
$stmt->bindParam(':user', $username);
$stmt->execute();
while ( $row = $stmt->fetch() ) {
if (!($sc > $stopcount)) {
$i++;
if( $row['time'] !== $lastTime ) {
if ( $lastTime === NULL ) {
echo '// close of loop';
} else {
echo '// loop grouping as title';
}
$lastTime = $row['time'];
}
if ($i >= $sc) { ?>
// the html to loop
<?
$sc++;
}
}
}
?>
Forward and Back buttons are easy enough to create. if $_GET['page'] * 10 > $total, active the next button, if $_GET['page'] > 1 activate previous button.
What I can't figure out is the correct formula and loop so I can always display the correct number of "page numbered" links. I want to always show 5 based on the 3rd number. So 1 would should 5 links: 1 - 5, 2 would also show 1 - 5, as would 3, 4 would show 2 - 6, 5 would show 3 - 7.
Now obviously, I could just add 2 and subtract 2 from the current $_GET[page] if the get page is greater than 3, but I need to take into account testing to see if the results go that high. So only if results are greater than 10 should number 2 show, and then if on page 16 pages 17 and 18 should only show if there are 170 and 180 results to display.
Perhaps I have just been staring at the code to long, but I can't seem to get a formula or loop correct in my head to even attempt the code page.
It was a fairly specific question. Wasn't sure if anyone would help with something so specific or not. Guess I learned.
Here is the answer to my own question:
<ul>
<li class="<? if ($_GET['page'] < '2') { echo 'disabled' ; } ?>">
<a href="<?
if ($_GET['page'] == '2') {
echo 'inbox.php';
} else {
echo '?page='.($_GET[page] - 1);
}
?>">Prev</a>
</li> <!-- previous button-->
<li style="<? if ($_GET['page'] - 2 < '1') { echo 'display:none;'; } ?>">
<a href="?page=<?
echo ($_GET[page] -2); ?>">
<? echo ($_GET[page] -2); ?>
</a>
</li> <!-- the button 2 before current spot if its greater than 0 -->
<li style="<? if ($_GET['page'] - 1 < '1') { echo 'display:none;'; } ?>">
<a href="?page=<?
echo ($_GET[page] -1); ?>">
<? echo ($_GET[page] -1); ?>
</a>
</li> <!-- the button 1 before current spot if its greater than 0 -->
<li class="disabled">
<? echo $_GET[page]; ?>
</li> <!-- current button disabled -->
<li style="<? if ($total - ($_GET[page] * 10) <= '0') { echo 'display:none;'; } ?>">
<a href="?page=<?
echo ($_GET[page] + 1); ?>">
<? echo ($_GET[page] +1); ?>
</a>
</li> <!-- the button 1 after current spot if results go that high -->
<li style="<? if ($total - ($_GET[page] + 1) * 10 <= '0') { echo 'display:none;'; } ?>">
<a href="?page=<?
echo ($_GET[page] + 2); ?>">
<? echo ($_GET[page] + 2); ?>
</a>
</li> <!-- the button 2 after current spot if results go that high -->
<li class="<? if ($total - ($_GET[page] * 10) <= '0') { echo 'disabled'; } ?>">
Next
</li> <!-- the next button if results go that high -->
</ul>
#bruce after seeing your solution, I'd like to give you my own solution.
$page = $_GET['page'];
$max_pages = ceil($total / $maxresults);
$min_pages = 1;
$start = max($min_pages, $page-2);
$end = min($max_pages, $start+2);
$nav = ($page > $min_pages ? '<li><</li>' : '' );
for ($i = $start; $i <= $end; $i++)
$nav .= '<li' . ($i == $page ? 'class="active"' : '' ) . '>' . $i . '</li>';
$nav .= ($page < $max_pages ? '<li>></li>' : '' );
I want to split pages to make it more smart and look nice,
I use this code to make Pagination
if (!isset($_GET['page'])){
$page = 1;
}
else {
$page = intval($_GET['page']);
}
$numbershownews = 1;
$x = ($page-1)*$numbershownews;
$select_news_all = $mysqli->query("SELECT id FROM news where FIND_IN_SET('$id_newscats_cat', cats) order by time desc");
$num_news_all = $select_news_all->num_rows;
$cn = $num_news_all/$numbershownews;
$select_news = $mysqli->query("SELECT * FROM news where FIND_IN_SET('$id_newscats_cat', cats) order by time desc limit $x,$numbershownews");
while ($rows_news = $select_news->fetch_array(MYSQL_ASSOC)){
$id_news = $rows_news ['id'];
$title_news = $rows_news ['title'];
}
i show pages by this code
<?
$pagenext = $page+1;
$pageprev = $page-1;
?>
<ul>
<li>
<?
if (($page == 1) or ($page == "")){
?>
<i class="fa fa-angle-double-right"></i>
<?
}else{
?>
<a class="link" href="<? echo "{$newurltitle_newscats_cat}-c-{$id_newscats_cat}-p-{$pageprev}.html"; ?>"><i class="fa fa-angle-double-right"></i></a>
<?
}
?>
</li>
<?php
for($i=0; $i<$cn; $i++){
$pagenumber = $i+1;
if($page == $pagenumber){
echo "<li>{$pagenumber}</li>";
}else{
?>
<li><a class="link" href="<? echo "{$newurltitle_newscats_cat}-c-{$id_newscats_cat}-p-{$pagenumber}.html"; ?>"><? echo $pagenumber; ?></a></li>
<?
}
}
?>
<li>
<?
if($page >= $cn){
?>
<i class="fa fa-angle-double-left"></i>
<?
}else{

<?
}
?>
it works well but it gives me pages like this 1,2,3,4,5,6,7,8,9,10 i want to split pages like this 1,2,3,4,...,9,10 how can i do this
thanks

This code allow the navigation between a query records, so it create a page foreach record in database and so shows one record time. How can i modify that code to paging every 10 records? So i want to show 10 records time and create a page for the next.
Sorry for my english (I'm italian) , i hope you can help me.
What you need first is the LIMIT statement from mysql. MySql states:
The LIMIT clause can be used to constrain the number of rows returned
by the SELECT statement. LIMIT takes one or two numeric arguments,
which must both be nonnegative integer constants (except when using
prepared statements).
With two arguments, the first argument specifies the offset of the
first row to return, and the second specifies the maximum number of
rows to return. The offset of the initial row is 0 (not 1):
As for how to implement it in your code I could not have written a better answer as the one found here.
Use LIMIT to get as many records as you wish.
Example:
SELECT * FROM tbl LIMIT 5,10; # Retrieve rows 6-15
Here is your modified code. This should work for your.
I haven't tested it but give it a try:
<?php
$host='localhost';
$user='root';
$password='root';
$database='database';
$startindex=(isset($_REQUEST['seek']) ? $_REQUEST['seek'] : 0);
$db=mysql_connect($host, $user, $password)
or die ("Impossibile connettersi al server $host");
mysql_select_db($database, $db)
or die ("Impossibile connettersi al database $database");
$queryCnt = "SELECT count(*) as cnt FROM ordini_master";
$CntRow=mysql_fetch_row(mysql_query($query, $db));
$CntData = $CntRow[0];
$step = 10;
$query="SELECT * FROM ordini_master LIMIT $startindex, $step";
$result=mysql_query($query, $db);
while ($row = mysql_fetch_assoc($result)) {
foreach($row as $k=>$v) {
$myfield=mysql_fetch_field($result, $k);
print($myfield->name . " : $v <br/>");
}
}
mysql_free_result($result);
mysql_close($db);
print("<br/>Seleziona il record<br/>");
for($index=0; $index<$CntData; $index=$index+$step) {
print("<a href=\"{$_SERVER['PHP_SELF']}?seek=$index\" >" .
($index+1) . "</a> ");
}
Use the information from tadman too.
It's very important to do something to prevent SQL injection and it's also necessary to use PDO or the mysqli extension because the mysql extension will not longer be supported.
You can use COUNT to display your records and create pages
function getLimitData($start,$limit){
//getting all items
$db = new PDO('mysql:host=localhost; dbname=data','root','');
$results = $db->query("SELECT * FROM table ORDER BY ID DESC limit $start,$limit");
$results = $results->fetchAll(PDO::FETCH_ASSOC);
return $results;
}
//database connection
$db = new PDO('mysql:host=localhost; dbname=data','root','');
//pagination pages
$nav_counter = basename($_SERVER['SCRIPT_FILENAME']);
$page_counter = $nav_counter;
$nav_counter = rtrim($nav_counter, ".php");
$cPage = $page_counter + 1;

$fourth_prev = $nav_counter - 4 ;
$fifth_prev = $nav_counter - 5 ;
$sixth_prev = $nav_counter - 6 ;
$seventh_prev = $nav_counter - 7 ;
//row count
$tableExists = $db->tableExist();
$ROW_COUNT = $db->getRowCount();
$numRows= 9; //number of items to be displayed

$pageNate = 'class="hide"';
}else{
$pageNate = 'class="exist"';

//displaying torrents
$start = 0;
$limit = $numRows;

I use below code for pagination.How to add first,previous,next,last links in pagination.
Only 9 paging numbers should allow in pagination.
