PHP Mysql Paginating results - php

Hey I am trying to have paginated results for a book store but I can not figure out why my links to other pages will not work. When I run this the original page loads the results but when I go to the next page it says items not found.
<?php
$host = '???'; //IP Address on domain name of the host for the database
$user ='???'; //the name of the user
$pass="???";//Our Password
//make the connection to the database
$con=mysql_connect($host,$user,$pass) or
die("Error connecting to Database");
$dbname = "???"; //we had a database name ???
mysql_select_db($dbname);
?>
<?php
echo "<br><h3><u>Available Books for Sell</u></h3><br>"; // promps user to order a book
$per_page=5;
if (isset($_GET["page"])) {
$page = $_GET["page"];
}
else {
$page=1;
}
// Page will start from 0 and Multiple by Per Page
$start_from = ($page-1) * $per_page;
$query="select * from Books limit $start_from,$per_page"; // create query using the $_GET 'id' sent
$result=mysql_query($query); //results from executing the mysql query
if(!$result) // if not results
{
echo" get Items error"; // print error
exit;
}
while($row=mysql_fetch_array($result)) // while there are results
{
echo
"<br>----------------------------------------------------------------------
<br>Title: ".$row['Title'].
"<br>Author: ".$row['Author']. //print row price, name, author
"<br>ISBN: ".$row['ISBN'].
"<br>Condition: ".$row['BookCondition'].
"<br>Price: ".$row['Price'].
"<br>Sellers Username: ".$row['Uname'];
echo"<br>";
echo"----------------------------------------------------------------------";
}
//Now select all from table
$query = "select * from Books";
$result = mysql_query($query);
// Count the total records
$total_records = mysql_num_rows($result);
//Using ceil function to divide the total records on per page
$total_pages = ceil($total_records / $per_page);
//Going to first page
echo "<center><a href='getItems.php?page=1'>".'First Page'."</a> ";
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='getItems.php?page=".$i."'>".$i."</a> ";
};
// Going to last page
echo "<a href='getItems.php?page=$total_pages'>".'Last Page'."</a></center> ";
?>

How to display only 5 records per page from my mysql database table through pagination?

I want to display five record per page through pagination (mysql,php,html,css) until all the records are displayed, navigation to pages must be like, Page: 1 2 3 4 5 6 7 7 8... Last.
HERE IS MY CODE TO VIEW ALL THE RECORDS FROM emp_master table.
I am new to PHP so please write an easily understandable code for pagination. I have seen few examples but they are not working.
<?php
$con=mysqli_connect("localhost","user","password","dataplus");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM emp_master");
echo "<table border='1'>";
$i = 0;
while($row = $result->fetch_assoc())
{
if ($i == 0) {
$i++;
echo "<tr>";
foreach ($row as $key => $value) {
echo "<th>" . $key . "</th>";
}
echo "</tr>";
}
echo "<tr>";
foreach ($row as $value) {
echo "<td>" . $value . "</td>";
}
echo "</tr>";
}
echo "</table>";
mysqli_close($con);

This code below is not working:

$dbuser="10053";

"--------------------------------<br>";
}
if( $page > 0 ) {
$last = $page - 2;
echo "Last 10 Records |";
echo "Next 10 Records";
}else if( $page == 0 ) {
echo "Next 10 Records";
}else if( $left_rec < $rec_limit ) {
$last = $page - 2;
echo "Last 10 Records";
}
mysql_close($conn);
If you want just PHP MySQL code, I usually use something like the following.
$page=max(intval($_GET['page']),1); // assuming there is a parameter 'page'
$itemsperpage = 5;
$total=100; // total results if you know it already otherwise use another query
$totalpages = max(ceil($total/$itemsperpage),1);
$query = "SELECT * FROM emp_master LIMIT ".(($page-1)*$itemsperpage).",".$itemsperpage; // this will return 5 items based on the page
You can use a library called dataTables that will auto paginate the data and you can easily customize it to suit your needs with the look and how many records to show per page. It also has a search field which enables users to search your data without any extra code.
All you have to do is include a couple of cdn's and the following code and everything works fine
$(document).ready(function(){
$('#myTable').DataTable();
});
Some examples here
you just should remove spaces in href and also make $page = $page + 1 when page is 0
if( $page > 0 ) {
$last = $page - 2;
echo "Last 10 Records |";
echo "Next 10 Records";
}else if( $page == 0 ) {
$page = $page + 1;
echo "Next 10 Records";
}else if( $left_rec < $rec_limit ) {
$last = $page - 2;
echo "Last 10 Records";
}

Here is the code working for me, just change your db name, username and password
and get pagination done. You can change $rec_limit value to your desired no. of records per page.
<?php
$host="localhost";
$username="68";
$password="67242";
$database="68";
$rec_limit = 5;
$conn = mysql_connect($localhost,$username,$password);
if(! $conn ) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('10');
/* Get total number of records */
$sql = "SELECT count(emp_id) FROM emp_master ";
$retval = mysql_query( $sql, $conn );
if(! $retval ) {
die('Could not get data: ' . mysql_error());
}
$row = mysql_fetch_array($retval, MYSQL_NUM );
$rec_count = $row[0];
if( isset($_GET{'page'} ) ) {
$page = $_GET{'page'} + 1;
$offset = $rec_limit * $page ;
}else {
$page = 0;
$offset = 0;
}
$left_rec = $rec_count - ($page * $rec_limit);
$sql = "SELECT eid,ename, email, quali, gender, contactno, birthdate, joiningdate,CURDATE(), TIMESTAMPDIFF( YEAR, birthdate, CURDATE( ) ) AS age ".
"FROM emp_master ".
"LIMIT $offset, $rec_limit";
$retval = mysql_query( $sql, $conn );
if(! $retval ) {
die('Could not get data: ' . mysql_error());
}
echo "<table border='1'>";
$i = 0;
while($row = mysql_fetch_array($retval, MYSQL_ASSOC)) {
if ($i == 0) {
$i++;
echo "<tr>";
foreach ($row as $key => $value) {
echo "<th>" . $key . "</th>";
}
echo "</tr>";
}
echo "<tr>";
foreach ($row as $value) {
echo "<td>" . $value . "</td>";
}
echo "</tr>";
}
echo "</table>";
if( $page > 0 ) {
$last = $page - 2;
echo "Last 5 Records | ";
echo "Next 5 Records";
}else if( $page == 0 ) {
$page = $page + 0;
echo "Next 5 Records";
}else if( $left_rec < $rec_limit ) {
$last = $page - 2;

}
mysql_close($conn);

i Give you an example of my project of pagination. Just you have to put your values in the code
$sql="SELECT * FROM tblname LIMIT $next,5";
$results = mysqli_query($conn,$sql);
}
else if (isset($_POST['prev']))
{
$prev1=$_POST['prev'];
$next=$_POST['prev'];
$prev=$prev1;
$sql="SELECT * FROM tablename LIMIT $prev,5";
$prev=$prev1;
$results = mysqli_query($conn,"SELECT * FROM tablename LIMIT $prev,10");
if($prev==0)
{
$prev = 0;
}
else
{
$prev=$next-10;
}
}
else
{
$next=0;
$prev=0;
$results = mysqli_query($conn,"SELECT * FROM tablename LIMIT $next,10");
}

Pagination not showing results on next page

Looking for some help please. I am using the following code to filter and show results which works fine. My problem is the results aren't passing on to the second page so the page becomes blank no errors. very new to this so all help is welcome.
$num_rec_per_page=2;
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("searchresults") or die("ERROR");
if (!isset($_POST['submit'])) exit();
$vars = array('companyname','location');
$verified = TRUE;
foreach ($vars as $v) {
if (!isset($_POST[$v]) || empty($_POST[$v])) {
$verified = FALSE;
}
}
if (!$verified) {
echo "Sorry no results found, please enter your search";
exit();
}
// isset function is also used in checking for the existence of data in $_POST
if (isset($_POST["companyname"]) && $_POST["companyname"] != '') {
$companyname = mysql_real_escape_string($_POST["companyname"]);
$companyname = " AND (companyname LIKE '%$companyname%')";
}
if (isset($_POST["location"]) && $_POST["location"] != '') {
$location = mysql_real_escape_string($_POST["location"]);
$location = " AND (location LIKE '%$location%')";
}
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * $num_rec_per_page;
$sql = "SELECT * FROM reviewsandtips WHERE member_id > 0". $companyname . $location . "LIMIT $start_from, $num_rec_per_page";
$sql_result = mysql_query($sql) or die (mysql_error());
// now echo the code for the table heading
if (mysql_num_rows($sql_result)>0) {
while ($row = mysql_fetch_assoc($sql_result)) {
}
$sql = "SELECT * FROM reviewsandtips WHERE member_id > 0". $companyname . $location;
$sql_result = mysql_query($sql); //run the query
$total_records = mysql_num_rows($sql_result); //count number of records
$total_pages = ceil($total_records / $num_rec_per_page);
echo "<a href='codetest.php?page=1'>".'|<'."</a> "; // Goto 1st page
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='codetest.php?page=".$i."'>".$i."</a> ";
}
echo "<a href='codetest.php?page=$total_pages'>".'>|'."</a> "; // Goto last page
} else {
echo '<tr><td colspan="5">No results found.</td></tr>';
}

how to implement pagination using PHP and MYSQL

I am trying to implement pagination using PHP and MySQL by using the following code .
I have taken help from internet and changed the code but not able to get the value of page variable so code is not working effectively
Can you suggest me where is the error in the program or how can i get the page variable value. The program is just simple to implement the pagination using PHP and MYSQL db.
code is as following.

<?php
$dbhost = 'localhost';
$dbuser = 'root';

if(! $conn ) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('test_db');
/* Get total number of records */
$sql = "SELECT count(cinno) FROM register_data ";
$retval = mysql_query( $sql, $conn );
if(! $retval ) {

}
$row = mysql_fetch_array($retval, MYSQL_NUM );
$rec_count = $row[0];
if( isset($_GET{'page'} ) ) {
$page = $_GET{'page'} + 1;
$offset = $rec_limit * $page ;
}else {
$page = 0;
$offset = 0;

echo "Cin No :{$row['cinno']} <br> ";
}

}else if( $left_rec < $rec_limit ) {
$last = $page - 2;
echo "Last 10 Records";
}
mysql_close($conn);
?>
</body>
</html>
I have cheked last page condition by finding $total_page and then comparing $page == $total_page. $left_rec method is not fit all the time.
// $left_rec = $rec_count - ($page * $rec_limit); not always give correct result
$total_page = ceil($rec_count/$rec_limit);
ceil() is a php function which returns the next highest integer value by rounding up. for more info read http://php.net/manual/en/function.ceil.php
Also you have spaces in your query string thats why you can't get page value and you need not to use $_PHP_SELF you can simply write
echo "<a href = '?page=$page'>Next 10 Records</a>"; or echo "<a href = 'index.php?page=$page'>Next 10 Records</a>"; if the code is in index.php

Pagination on sql fetched row in php

I want to use pagination on sql fetched row. I am using this code:
<?php
$rec_limit = 4;
$sql = "SELECT count(id) FROM wp_wct8 ";
$retval = mysql_query( $sql);
if(! $retval ) {
die('Could not get data: ' . mysql_error());
}
$row = mysql_fetch_array($retval, MYSQL_NUM );
$rec_count = $row[0];
if( isset($_GET{'page'} ) ) {
$page = $_GET{'page'} + 1;
$offset = $rec_limit * $page ;
}else {
$page = 0;
$offset = 0;
}
$left_rec = $rec_count - ($page * $rec_limit);
$sql = "SELECT id, name, insurance ".
"FROM wp_wct8 ".
"LIMIT $offset, $rec_limit";
$retval = mysql_query( $sql);
if(! $retval ) {
die('Could not get data: ' . mysql_error());
}
while ($b = mysql_fetch_array($retval)){
echo $b['name'];
echo $b['insurance'];
}
if( $page > 0 ) {
$last = $page - 2;
echo "Last 4 Records |";
echo "Next 4 Records";
}else if( $page == 0 ) {
echo "Next 4 Records";
}else if( $left_rec < $rec_limit ) {
$last = $page - 2;
echo "Last 4 Records";
}
?>
but pagination not working... when i click on show next 4 records it is showing same records not next..please helpme... thanks in advance
I don't recommend you to put this code online as it's vulnerable to SQL injection. (Use prepared statements with PDO instead or at least, escape your input in the SQL query.)
I assume the error are the whitespaces in your links. So try removing the whitespaces, e.g. echo "Last 4 Records |";

PHP Pagination Last id record

I've the following Pagination code :
$rec_limit = 3;
/* Get total number of records */
$query = "SELECT count(id) FROM news";
$result = mysql_query($query);
if(!$result)
{
die('Could not get data: ' . mysql_error());
}
$row = mysql_fetch_array($result, MYSQL_NUM );
$rec_count = $row[0];
if( isset($_GET{'page'} ) )
{
$page = $_GET{'page'} + 1;
$offset = $rec_limit * $page ;
}
else
{
$page = 0;
$offset = 0;
}
$left_rec = $rec_count - ($page * $rec_limit);
$query2 = "SELECT * ".
"FROM news ".
"LIMIT $offset, $rec_limit";
$result2 = mysql_query( $query2 );
if(! $result2 )
{
die('Could not get data: ' . mysql_error());
}
while($row = mysql_fetch_array($result2, MYSQL_ASSOC))
{
echo " ID :{$row['id']} <br> ".
" News : {$row['title']} <br> ".
" Date : {$row['date']} <br> ".
"--------------------------------<br>";
}
if( $page > 0 )
{
$last = $page - 2;
echo "Last 3 Records |";
echo "Next 3 Records";
}
else if( $page == 0 )
{
echo "Next 3 Records";
}
else if( $left_rec < $rec_limit )
{
$last = $page - 2;
echo "Last 3 Records";
}
The code works perfectly as needed, except that the a href part where it shows the Next 3 records link even when there is no news left. By that i mean, it keeps opening up pages with empty records ! How can i remove Next 3 Records link when it reaches the last news ID.
Thank You
Just bring the last condition above the other two and change < to <=:
if($left_rec <= $rec_limit)
{
$last = $page - 2;
echo "Last 3 Records";
} else if ( $page > 0 )
{
$last = $page - 2;
echo "Last 3 Records |";
echo "Next 3 Records";
}
else if( $page == 0 )
{
echo "Next 3 Records";
}
