I have been messing around, and been trying to make this script work (for later implenting it in my own projects). It works fine, beside that I when I click on a new page, the results doesnt' change..
here is the script:
<?php
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * 5;
$sql = "SELECT * FROM employee ORDER BY emp_id ASC LIMIT $start_from, 20";
$rs_result = mysql_query ($sql);
?>
<table>
<tr><td>Name</td><td>Phone</td><td>Salary</td></tr>
<?php
while ($row = mysql_fetch_assoc($rs_result)) {
?>
<tr>
<td><?php echo $row['emp_id']; ?></td>
<td><?php echo $row['emp_name']; ?></td>
<td><?php echo $row['emp_salary']; ?></td>
</tr>
<?php
};
?>
</table>
<?php
$sql = "SELECT COUNT(emp_name) FROM employee";
$rs_result = mysql_query($sql);
$row = mysql_fetch_row($rs_result);
$total_records = $row[0];
$total_pages = ceil($total_records / 5);
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='pagination?page=".$i."'>".$i."</a> ";
};
?>
Actually there seems nothing fundamentally wrong. Did you try a hard reload in your browser ?
Use this in the unshown head part of your page to get rid of some caching issues:
<html>
<head>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
<meta http-equiv="cache-control" content="no-cache">
</head>
...
</html>
I changed some things anyway:
$perpage contains the number of entries per page nice in one place
never use unsanitized values in sql so I (int)ed the $_GET
--- need this line for the code to show ---
<?php
$perpage = 5;
if (isset($_GET["page"])) { $page = abs ((int)$_GET["page"]); } else { $page=1; };
$start_from = ($page-1) * $perpage;
$sql = "SELECT * FROM employee ORDER BY emp_id ASC LIMIT $start_from, $perpage";
$rs_result = mysql_query ($sql);
?>
<table>
<tr><td>Name</td><td>Phone</td><td>Salary</td></tr>
<? php
while ($row = mysql_fetch_assoc($rs_result)) {
?>
<tr>
<td><?php echo $row['emp_id']; ?></td>
<td><?php echo $row['emp_name']; ?></td>
<td><?php echo $row['emp_salary']; ?></td>
</tr>
<?php
};
?>
</table>
<?php
$sql = "SELECT COUNT(emp_name) FROM employee";
$rs_result = mysql_query($sql);
$row = mysql_fetch_row($rs_result);
$total_records = $row[0];
$total_pages = ceil($total_records / 5);
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='pagination?page=".$i."'>".$i."</a> ";
};
?>

enter image description hereThe problem is the content of my table is not showing. It is counting and show the the equal row from my database but no content is showing. Can you please help me?

There are few things wrong left over from your edited question earlier, most particularly this one where you changed the single quotes from ORDER BY 'so_id' to using backticks:
ORDER BY `so_id`
More on what are called "Identifier Qualifiers" can be seen in the following reference:
https://dev.mysql.com/doc/refman/8.0/en/identifier-qualifiers.html
Then about <? echo. Those are what are called short tags and if they're unabled, you need to change them to <?php echo or <?= which also does the same.
Then your quotes in COUNT('so_id'). Either remove them or replace them with backticks.
COUNT(`so_id`)
Finally; you're going to receive undefined index notices for these as soon as the page is loaded:
<td><? echo $row["so_customer"]; ?></td>
<td><? echo $row["so_address"]; ?></td>
Therefore and to avoid / fix those errors, replace them with the following:
<td><?php if(isset($row['so_customer'])){ echo $row["so_customer"]; } ?></td>
<td><?php if(!empty($row['so_address'])){ echo $row["so_address"]; }?></td>
Enabling error reporting for the PHP and error handling for the MySQL, would have been of help during development/debugging.

I am implementing a website in which admin has access to maintain stock. I am displaying stock from the database in html table. i have used pagination to display 10 records per page. I want that when i am on page 1 it displays "Showing 1-10 of total record" and when i am on page 2 it displays "Showing 11-20 of total record" and vice versa.
CODE:
<?php
$link = mysql_connect("localhost", "root", "");
mysql_select_db("login", $link);
$result = mysql_query("SELECT COUNT(*) FROM add_stock");
$row = mysql_fetch_row($result);
$num = $row[0];
?>

<th>Material</th>
<th>Size</th>
<th>Description</th>
<th>Quantity</th>
<th><b>Image</b></th>

$num_rec_per_page=10;
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * $num_rec_per_page;
$sql = "SELECT * FROM add_stock ORDER BY id DESC LIMIT $start_from, $num_rec_per_page";
$rs_result = mysql_query ($sql); //run the query
$total_records = mysql_num_rows($rs_result); //count number of records
$total_pages = ceil($total_records / $num_rec_per_page);
$next_page = $page + 1;
$prev_page = $page - 1;
$i= $start_from;
$start=1;
while ($result=mysql_fetch_array($rs_result) )
{
?>

<?php
$i++;
} ?>
</table>
<?php
$sql = "SELECT * FROM add_stock";
$rs_result = mysql_query($sql); //run the query
$total_records = mysql_num_rows($rs_result); //count number of records
$total_pages = ceil($total_records / $num_rec_per_page);

for ($i=1; $i<=$total_pages; $i++) {

}
if ($page==$total_pages) {
$page=$total_pages;
}
else{

echo "<a href='viewstock.php?page=$total_pages'><b>»</b></a> ";
?>
</div>
</div>
<p>Displaying <?php echo $start ?> - <?php echo $total_records ?> of Records: <?php echo $num ?></p>
This will work:
<p>Displaying <?php echo $start_from+1 ?> - <?php echo $start_from + $total_records ?> of Records: <?php echo $num ?></p>
as long as you:
1) Move the output below the code where the numbers you need are calculated
2) Don't re-use the variable $total_records after your SELECT * FROM add_stock. Instead give this instance of the variable a new name so it can't be confused with the earlier version, which means something different, and is needed for your output.
Please note also my first comment regarding your SQL Injection vulnerability, which you should take steps to fix as soon as possible.
I am developing a page where a user can enter the limit of the table in pagination. While I am doing this the data I enter is taken and query is performed according to that. But as I click on another page of that table the value is reset to default which I set to 5 here.
<?php session_start(); ?>
Submit New record<br><br>
<form method="post">
<input type="text" name="dlimit">
<input type="submit" name="submit">
</form>
<?php
$database = 'test';
require 'connection.php';
if(!isset($_POST['submit']))
{
$limit = 5;
}
else
{
$dlimit = $_POST['dlimit'];
$limit = $dlimit;
}
#$id = $_GET['id'];
if($id==""||$id==null)
{
$page=0;
}
else
{
$page = ($id*$limit)-$limit;
}
$qq ="select * from record limit $page,$limit";
$result = $link -> query($qq);
?>
<table border="1"><th>ID</th>
<th>Name</th>
<th>qualification</th>
<th>address</th>
</tr>
<?php
while ($row = mysqli_fetch_object($result))
{
?>
<tr>
<td><?php echo $row->id ?></td>
<td><?php echo $row->user_name ?></td>
<td><?php echo $row->qualification ?></td>
<td><?php echo $row->address ?></td>
</tr>
<?php
}
?>
</table>
<?php
$query = "SELECT * FROM record";
$result = $link -> query($query);
$rows = mysqli_num_rows($result);
$rr = $rows/$limit;
$rr = ceil($rr);
for ($i=1; $i<=$rr ; $i++) {
?>
<?php echo #$i;?>
<?php
}
mysqli_close($link)
?>
Run the above code and check. If my words are not clear to you.
I think that the $_POST data is missing. You click on the link, so the new page will open without POST infos.
You can change this, if you switch to GET instead of POST. You can add the GET parameter to your <a href=""> Tag.
For example
<a href="pagination.php?page=5&dlimit=100
Also try to avoid the #error suppression and don't pass the $_POST/$_GET Vars directly to your sql string. Bad people could use it for SQL Injections
So I got the answer for my question. I am posting it here if anyone need it on later basis.

Again I am mentioning here that files which I included here are just connection where I filled my connection details and other is my record entry file where data is entered by the user.
I've tried to make a pagination with PHP, but it seems to not work. I want to limit my data which showing in each page, I have this code and it uses PHP code:
showUsers.php
<?php
$query = mysql_query("select * from users");
while ($data = mysql_fetch_array($query)) {
?>
<td><?php echo $data['no_peg']; ?></td>
<td>
<?php
echo $data['username'];
//previlage admin
if ($_SESSION['role'] == 'admin') {
?>
<div class="row-actions">
Edit
<?php if ($data['role'] != 'admin') {?>
| Delete
<?php } ?>
</div>
<?php } ?>
</td>
<td><?php echo $data['fullname']; ?></td>
<td><?php echo $data['telephone']; ?></td>
<td><?php echo $data['email']; ?></td>
I want to show just 10 names per page, to avoid long scrolling, but how can it work?
Hi，if you want to make a pagination, you should add in a LIMIT clause into your queries, like this:
SELECT* FROM users LIMIT 0, 10
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.
So, what's the next?
You need to add a parameter to your query url specifies the number of page when you list the users.
Such as:
showUsers.php?page=1
Then, in your program, you can get parameter by this:
$page = isset($_GET['page']) ? $_GET['page'] : 1;
I hope it will help you, I'm new here.
<?php
$sqlCount = "select count(id_user) from users";
$rsCount = mysql_fetch_array(mysql_query($sqlCount));
$totalData = $rsCount[0];
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$limit = 10;
$start_from = $limit * ($page - 1);
$sql_limit = "SELECT * FROM users limit $start_from, $limit";
$result = mysql_query($sql_limit);
while ($data = mysql_fetch_array($result)) {
?>
<td><?php echo $data['no_peg']; ?></td>
<td>
<?php
echo $data['username'];
//previlage admin
if ($_SESSION['role'] == 'admin') {
?>
<div class="row-actions">
Edit
<?php if ($data['role'] != 'admin') {?>
| Delete
<?php } ?>
</div>
<?php } ?>
</td>
<td><?php echo $data['fullname']; ?></td>
<td><?php echo $data['telephone']; ?></td>
<td><?php echo $data['email']; ?></td>
</tr>
<?php
}
?>
<?php
$totalPage = ceil($totalData / $limit);
echo 'Page : ';
for($i = 1; $i <= $totalPage; $i++){
if($page != $i){
echo '['.$i.'] ';
}else{
echo "[$i] ";
}
}
?>
Where is your pagination code? Your code just shows this query:
$query = mysql_query("select * from users");
But for basic pagination you need to set a LIMIT like so:
$query = mysql_query("select * from users LIMIT 0,10");
So that would only grab the first 10 items. And then—let’s say, on page 2 you could do this:
$query = mysql_query("select * from users LIMIT 11,10");
That would grab the next 10 items starting from item 11.
That’s the basic concept. But you have to code the logic for passing along pagination values & such.
<?php
if(is_int($_GET('pageNo'))) // getting the page number from the URL i.e script.php?pageNo=2
{
$query = mysql_query("select * from users limit ".$_GET['pageNo']." ,10");
while ($data = mysql_fetch_array($query)) {
?>
<td><?php echo $data['no_peg']; ?></td>
<td>
<?php
echo $data['username'];
//previlage admin
if ($_SESSION['role'] == 'admin') {
?>
<div class="row-actions">
Edit
<?php if ($data['role'] != 'admin') {?>
| Delete
<?php } ?>
</div>
<?php } ?>
</td>
<td><?php echo $data['fullname']; ?></td>
<td><?php echo $data['telephone']; ?></td>
<td><?php echo $data['email']; ?></td>
</tr>
<?php
}
} // not sure where the closing if should be you figure it out :P
?>
How would I go about making a pagination script for this MySQL & PHP query.
if (isset($_GET['c'])) {
$c = $_GET['c'];
}
$query = mysql_query("SELECT * FROM Categories WHERE category = '$c' ");
WHILE($datarows = mysql_fetch_array($query)):
$id = $datarows['id'];
$category = $datarows['category'];
$code = $datarows['code'];
endwhile;
$query2 = mysql_query("SELECT * FROM Games WHERE category = '$code' ");
WHILE($datarows_cat = mysql_fetch_array($query2)):
$title = $datarows_cat['title'];
$description = $datarows_cat['description'];
$imgurl = $datarows_cat['image_name'];
$category = $datarows_cat['category'];
$views = $datarows_cat['view_count'];
$pagename = $datarows_cat['pagename'];
$featured = $datarows_cat['featured'];
if ($featured =="1") {$f = "<img src='http://my-site.com/images/star.png' width='13px' title='Featured Game' /> Featured"; } else {$f = "";}
if(is_int($views/2)) {
$views = $views / 2;
} else { $views = $views / 2 + .5; }
if (strlen($description) > 95) {
$desc= substr($description,0,95);
$desmod = "$desc...<br/>- Read More";
}
else {$desmod = "$description";}
echo "$f - $title - $desmod<br/>";
endwhile;
And when I visit http://my-site.com/categories/Action for instance, The code looks up that category in my category table, then once it gets the unique code for that category, It runs another query to find all games in another table with that category code. Currently, however, I have 200+ games loading for a single category which causes a great amount of loading time.
Thanks for your help!
First of all find out how many games are there for a specific category
change the line
$query2 = mysql_query("SELECT * FROM Games WHERE category = '$code' ");
to
$sql="SELECT * FROM Games WHERE category = '$code' ";
$query_count=mysql_query($sql);
Add following after it
$per_page =30;//define how many games for a page
$count = mysql_num_rows($query_count);
$pages = ceil($count/$per_page);
if($_GET['page']==""){
$page="1";
}else{
$page=$_GET['page'];
}
$start = ($page - 1) * $per_page;
$sql = $sql." LIMIT $start,$per_page";
$query2=mysql_query($sql);
Then display the numbers of pages where you want
<ul id="pagination">
<?php
//Show page links
for ($i = 1; $i <= $pages; $i++)
{?>
<li id="<?php echo $i;?>"><?php echo $i;?></li>
<?php
}
?>
</ul>
Use CSS for pagination this will do the trick
//database connation
<?php
$conn = new mysqli("localhost", "root", "","database_name");
?>
