I have this code:
$total = 12;
$limitPerPage = 6;
$totalPages = ceil($total / $limitPerPage);
$p = $_GET['p'];
echo $p;
echo 'Total pages: ' . $totalPages . '<br /><br />';
$limitRow = 3;
$totalRow = ceil($total / $limitRow);
for($i = 1; $i <= $totalRow; $i++){
$row = ($i * $limitRow) - $limitRow;
echo "From " . $row . ": ";
for($j = 1; $j <= $limitRow; $j++){
echo $row + $j . " ";
}
echo '<br />';
What i want is to get pagination something like that:
First page would have:
From 0: 1 2 3
From 3: 4 5 6
Second page:
From 6: 7 8 9
From 9: 10 11 12
Etc...
Now i have set per page 6, but maybe later i change to 9 or 12...
This is code for geting from sql and it needs to be in that way with for loops throught each for and than limiting each row.
Any ideas how to reach that? I know i can just make $limit 6 and will get 6 per page, but main important thing is that i limit each row.
UPDATE:
It works in that way:
<div id="ref1"></div>
<div id="ref2"></div>
<div id="ref3"></div>
<div id="completeref">
<div id="ref1"></div>
<div id="ref2"></div>
<div id="ref3"></div>
</div>
That way is for each row after 3 divs then i create new div with all 3 divs in it.

I have number from 1 until 200, number will be printed in a page, each page has a limit by 81. When reach 81 then print into the next page.
This is output i want:
number = 200;
print number 1 - 81 in page 1
create new page
print number 82 - 162 in page 2
create new page
print number 163 - 200 in page 3
How to do it in PHP?
Update:
I mean i just want to print like above. No need of size of paper.
Here's what i have done
$number = 200;
$limit = 81;
$page = ceil($number/$limit);
for($i = 0; $i < $page; $i++){
echo "print number 1 - ". 200-81 ." in page".$i; // i'm stuck in here
}
I think this might work:
$number = 200;
$limit = 81;
$page = ceil($number/$limit);
for($i = 0; $i < $page; $i++){
$start = $i*$limit+1;
$last = ((($i+1)*$limit));
$last = $last>$number?$number:$last;
echo "<br>print number $start - $last in page".($i+1);
}
I am fetching username and Id from the database. I have more than 500 usernames. I have to display pagination number only 1 to 5 and last pagination number.
Example:- pagination number is:- 1 2 3 4 5...20(last number).
Now I am getting all numbers in horizontal. Would you help me in this?
Can anyone help me with NEXT and LAST in pagination?
include('../db/connection.php');
$reclimit = 3;
if(isset($_GET['page'])){
$page = $_GET['page'];
} else {
$page = 1;
}
$start = (($page-1) * $reclimit);
$sql = "SELECT * FROM request";
$records =$conn->query($sql);;
$total = $records->num_rows;
$tpages = ceil($total / $reclimit);
$search_sql="SELECT * FROM request LIMIT ".$start."," .$reclimit;
$search_result = $conn->query($search_sql);

The pagination which you are using is simple and working one. But the pagination which you are searching is smart way and you should achieve this by using some if conditions. Similar answer are there in SO. Go to the following, this may help you
Smart pagination algorithm
PHP pagination
Limit pagination page number
It's a simple idea, but I didn't test it. Edit foreach displaying numbers:
$pgStart = 1;
if (isset($_GET['page'])) { // get first showing number = current page - 2
$pg = $_GET['page'] - 2;
$pgStart = $pg + 5 > $tpages ? $tpages - 4 : $pg; //EDIT fix when reach pages end
$pgStart = $pg < 1 ? 1 : $pg; // This must be after ending correction (previous line)
}
if ($pgStart > 1) { // show 1
echo '1 ... ';
}
for($i = $pgStart; $i <= $tpages && $i < $pgStart + 5; $i++) { // show 5 pages
echo ' '.$i.' ';
}
if ($i < $tpages) { // show last
echo ' ... '.$tpages.'';
}
EDIT
Output of this script with $_GET['page'] = 7 and $tpages = 20 from php sandbox is (without linebreaks):
1 ...
5
6
7
8
9
... 20
I have my pagination page links like this.And the pagegrows like:
1 2 3 4 5 6 7 ,8,9,10 and goes on.
But i want to limit this so if there is more than 5 pages it shall only show 5 links like this:
1 2 3 4 5... 97 98 99
where 99 is the last page.
And if you go to next page it will only change the first pages like this:
3 4 5 ... 97 98 99
function pagination($current_page_number, $total_records_found, $query_string = null)
{
$page = 1;
echo "Page: ";
for ($total_pages = ($total_records_found/NUMBER_PER_PAGE); $total_pages > 0; $total_pages--)
{
if ($page != $current_page_number)
echo "<a href=\"?page=$page" . (($query_string) ? "&$query_string" : "") . "\">";
echo "$page ";
require_once('inc/database.php');
define("NUMBER_PER_PAGE", 5); //number of records per page of the search results
$page = ($_GET['page']) ? $_GET['page'] : 1;
$start = ($page-1) * NUMBER_PER_PAGE;
$sql = "SELECT * FROM members WHERE 1=1";
$total_records = mysql_num_rows(mysql_query($sql));
//we limit our query to the number of results we want per page
$sql .= " LIMIT $start, " . NUMBER_PER_PAGE;
// we display our pagination at the top of our search results
pagination($page, $total_records, "id=$id&username=$username&email=$email");
$loop = mysql_query($sql)
or die ('cannot run the query because: ' . mysql_error());
while ($record = mysql_fetch_assoc($loop))
echo "<br/>{$record['id']}) " . stripslashes($record['username']) . " - {$record['email']}";
echo "<center>" . number_format($total_records) . " search results found</center>";
if ($page != $current_page_number)
echo "</a>";
$page++;
Pagination is one of those things that has been done so many times that you're better off figuring out how to use a pre made class like this one http://code.tutsplus.com/tutorials/how-to-paginate-data-with-php--net-2928
The basics of what you need to do are calculate how many links you want to see on either side of the elipses ... and then make loops to create those links. The ceil() function may be new for you, but it returns a fraction always rounded up.
$buffer = 3;
$results_per_page = 5;
$page = ($_GET['page']) ? $_GET['page'] : 1;
$start = ($page-1) * $results_per_page;
$sql = "SELECT * FROM members WHERE 1=1";
$total_records = mysql_num_rows(mysql_query($sql));
$total_pages = ceil(intval($total_records) / $results_per_page);
for ($x = $page - $buffer; $x < $page; $x++){
echo " $x";
}
echo " ... ";
for ($x = $total_pages - $buffer; $x <= $total_pages; $x++){
echo " $x";
}
This quick little bit of code does not take in to consideration result sets small enough to fit all links in to one line. Which is why I suggest using the pagination classes that exist already.
I am, using the Codeigniter pagination library,
I am wondering how I can grab the number of the first and last items displayed using the pagination class?
So, if I had 12 results, and per_page was set to 5. I would want
Page 1: Displaying 1 to 5 of 12 results
Page 2: Displaying 6 to 10 of 12 results
Page 3: Displaying 11 to 12 of 12 results.
Keeping it simple.
You need 3 variables. Result start, result end (in the page, not the whole) and total result.
You already know the total results (from the pagination). Let's call it $total.
so, now get the current page ($curpage) value from CI instance. Then,
$result_start = ($curpage - 1) * $per_page + 1;
if ($result_start == 0) $result_start= 1; // *it happens only for the first run*
for $result_end, you just need to add the per page value but considering it'll be 1 less,
$result_end = $result_start+$per_page-1;
if ($result_end < $per_page) // happens when records less than per page
$result_end = $per_page;
else if ($result_end > $total) // happens when result end is greater than total records
$result_end = $total;
send all those 3 values to view.
echo "displaying $result_start to $result_end of $total";
itachi's solution works great except you need to handle the case where the last page has less than $per_page elements.
if ($result_end > $total) {
$result_end = $total;
}
In CodeIgniter Controller file
$params['limit'] = 15;
$params['offset'] = ($this->input->get('per_page')) ? $this->input->get('per_page') : 0;
$config = $this->config->item('pagination');
$config['per_page'] = $params['limit'];
$config['base_url'] = site_url('cy_controller/action?');
$config['total_rows'] = $this->abcd_model->get_count($params);
$this->pagination->initialize($config);
$data['merchant'] = $this->abcd_model->get_all($params);
$countMerchant = count($data['merchant']);
if ($params['offset'] == 0) {
$find_total_record = $countMerchant;
} else {
$valuec = $params['offset'] + $params['limit'];
if ($valuec > $config['total_rows'])
$find_total_record = $params['offset'] + $countMerchant;
else
$find_total_record = $params['offset'] + $params['limit'];
}
$per_page_total = $find_total_record;
$initial = $params['offset'] == 0 ? 1 : $params['offset'];
$data['showing'] = "Showing " . $initial . " to " . $per_page_total . " of " . $config['total_rows'] . " results";
$data['_view'] = 'cy_controller/action';
$this->load->view('layouts/main', $data);
And in view file
<div class="pull-left">
<?php echo $showing; ?>
</div>
<table><tr>
<?php
for($i=0;$i<15;$i++) {
if($i%5 == 0) {echo '</tr> <tr>';}
?><td><?php echo $i ?></td>
<?php
}?>
</tr>
</table>
this generate:
0 1 2 3 4
5 6 7 8 9
10 11 12 13 14
how can I make:
0 3 6 9 12
1 4 7 10 13
2 5 8 11 14
?
You need a nested loop
<table>
<?php
$rows = 3;
for($i=0 ; $i < $rows ; $i++ ) {
echo "<tr>";
for( $j = 0 ; $j < 5 ; $j++ ) {
echo "<td>" . ($j * $rows + $i) . "</td>";
}
echo "</tr>";
}
?>
</table>
I tried to make the variable names descriptive:
<table>
<?php
// Set the number of rows, cols, and starting number here:
$number_rows = 3;
$number_cols = 5;
$starting_num = 0;
// You can use foreach w arrays... much easier
$rows = range(0,$number_rows - 1);
$cols = range(0,$number_cols - 1);
foreach($rows as $one_row) {
?>
<tr>
<?php
foreach($cols as $one_col) {
// Do the calculation
echo "<td>" .
($starting_num + $one_col + ( max($rows) * $one_col ) + $one_row) .
"</td>";
}
?>
</tr>
<?php
}
?>
</table>
Working example like in the OP.
Now let's say you want to go from (1300-1431), then you start at 1300 and want a 4 x 8.
$number_rows = 8;
$number_cols = 4;
$starting_num = 1300;
Like this.
There are two "tricks."
The first is using range() to quickly define an array integers. I find arrays more pleasant to work with than raw numbers, since arrays can be worked on with the intuitive construct of foreach().
The second is figuring out how to know what number to print if you have the column, row, and starting, number. It's simplest to figure out the numbers for the first row and go from there. Let's number the rows and cols from 0. So col:0 row:0 will be the starting number. Col:1 Row:0, the number to the right, will just be the starting number + one (the column number) + the number of rows less one (easiest to see by looking at the matrix of number), and the number of rows less one is the maximum number in the rows array. So for the first row we have:
$starting_num + $one_col + ( max($rows) * $one_col )
then all we just add the row number to take that into account, and we've got it all:
$starting_num + $one_col + ( max($rows) * $one_col ) + $one_row
Tested example with given start and end:
<table>
<?php
$start = 1300;
$end = 1432;
$n = $end - $start + 1;
$cols = 5;
$rows = ceil($n / $cols);
for($i=0 ; $i < $rows ; $i++ ) {
echo "<tr>";
for( $j = 0 ; $j < $cols ; $j++ ) {
$val = $j * $rows + $i;
echo "<td>";
echo ($val < $n) ? $val + $start : ' ';
echo "</td>";
}
echo "</tr>";
}
?>
