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");
?>

Good day, I have an HTML table and I use paging on it so that only a certain amount of items is shown. The problem is that I need to have multiple selections with checkboxes and that works for a single page but I need that to work between pages. So for example on page 1 you choose 3 items and in the next page you choose 5 items and when GET happens I need to have all those items in one place so that I can store them in a variable.
<?php
include("connect.php"); //database connection file
$limit = 7;
if ( isset($_GET['page']) ) {
$page_no = $_GET['page'];
} else {
$page_no = 1;
}
$start_from = ($page_no-1)*$limit;
$sql = "SELECT * FROM emp_info LIMIT $start_from,$limit ";
$result = mysqli_query($conn , $sql);
?>
<form method="GET" action="project.php?name=<?php echo
$data['name']; ?>">
<div class="container">
<h2>employee information:</h2>
<table class="table table-striped table-hover">

<tr>
<th>EmpId</th>
<th>Name</th>
<th>Email</th>
</tr>
</thead>
<tbody>
<?php
$info = "SELECT * FROM emp_info LIMIT $start_from,$limit ";
//query to select the data from database
$query = mysqli_query ($conn , $info);
while ( $data = mysqli_fetch_assoc ($query) )
{ //query to fetch the data
$_SESSION['emp_name']=$data['name'];
?> <tr>
<td><?php echo $data['emp_id'];?></td>
<td>
<a href="project.php?id=<?php echo $data['emp_id'];?>&name=<?php echo $data['name']; ?>">
<input type="checkbox" name="check_list[]" value="<?php echo $data['name'];?>">
</a> <?php echo $data['name'];?>
</td>
<td><?php echo $data['email'];?></td>
</tr>
<?php }
?>
</tbody>
</table>
<ul class="pagination">
<?php
$sql = "SELECT COUNT(*) FROM emp_info";
$result = mysqli_query($conn , $sql);
$row = mysqli_fetch_row($result);
$total_records = $row[0];

$total_pages = ceil($total_records /

I recommend reseaching abit of Javascript and more specificly aJax to solve this issue.
You need somewhere to store the information that has been selected in order to use it somewhere else.
I have problem with my pagination href link. here is my current php file.
<?php
$query = $_GET["q"];
$s= mysqli_query($connection,$query);
$page = (int)(!isset($_GET["page"]) ? 1 : $_GET["page"]);
if ($page <= 0) $page = 1;
$per_page = 10; // Set how many records do you want to display per page.
$startpoint = ($page * $per_page) - $per_page;
$querylimited = $query . " LIMIT {$startpoint} , {$per_page}";
$_SESSION["query"] = $query;
if(!empty($_POST))
{
$result = mysqli_query($connection,$querylimited);
}
else
{
$page = (int)(!isset($_GET["page"]) ? 1 : $_GET["page"]);
if ($page <= 0) $page = 1;
$per_page = 10; // Set how many records do you want to display per page.
$startpoint = ($page * $per_page) - $per_page;
$s= mysqli_query($connection,$_SESSION["query"]);
$querylimited = $_SESSION["query"] . " LIMIT {$startpoint} , {$per_page}";

This is $_GET('p')

now problem is when I click on page 2 link it does not add &page=2with it.
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);
?>

<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> ";
};

I'm trying to get an id from the users database so that I can link to about.php?id=$id1 and I'm using 2 while loops to do that. I end up getting what I want, about.php?id=$id1 but there are duplicate entries...
Here's the code.

How can I get the selected category id after 1st page in pagination?
Do you pass though category in the request? You haven't given us that information (what is the value of qstr in the javascript?), but I'd guess not.
You're also passing it straight into an SQL query, which leaves you open to injection.
You should use mysql_escape_string() to fix that.
Post it with the AJAX call and return it
Store it in a local JS variable
Add it to the URL
...
You seem to be aware that $_GET['p'] gets the value of the 'p' parameter passed in the querystring. Well $_REQUEST['category'] is doing the same thing. (Technically $_REQUEST checked everything in $_POST, $_GET and $_COOKIE).
So if you haven't set the 'category' in the querystring then it wont contain anything in your code.
You should add ?category=XXX&sid=RAND... to your url
Better use $category = isset($_GET['category']) ? (int)$_GET['category'] : 0;
