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";
}

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);

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 ) {

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");
}
I have following code to display only 10 records at one page. When I load the page for the first time, first 10 records are displayed well (see screenshot)
. But when I click on "Next 10 records", the same URL is not loaded with extra GET parameters using $_SERVER['PHP_SELF'].
My address bar shows this instead:
http://localhost/PHP/$_SERVER['PHP_SELF']?page=$page
Here is my complete code;
<?php
$con = #mysqli_connect( "localhost:3306", "root", "P#ssw0rd", "world" ) or die ("Couldn't connect to server");
//get total number of records
$query = "SELECT count(ID) FROM city";
$result = mysqli_query ( $con, $query) or die ("Couldn't execute SELECT query: ". mysqli_error($con));
$rec_count = mysqli_num_rows($result);
$rec_limit = 10; //number of records to display
if( isset($_GET['page']) ){ //when user clicks link
$page = $_POST['page'] + 1; //page count increment by 1
$offset = $rec_limit * $page;
}
else{ //user has not yet clicked any link
$page = 0;
$offset = 0;
}
//xxxxxxxx $rec_count is taken from result set
$left_rec = $rec_count - ($page * $rec_limit); //number of records remaining to display
$display_query = "SELECT * FROM city LIMIT $offset, $rec_limit";
$display_result = mysqli_query ( $con, $display_query) or die ("Couldn't execute SELECT query: ". mysqli_error($con));
echo "<table>";
echo "<th>ID</th> <th>Name</th> <th>Country Code</th> <th>District</th> <th>Population</th>";
while( $row = mysqli_fetch_assoc($display_result) ){
extract($row);
echo "<tr>
<td>$ID</td>
<td>$Name</td>
<td>$CountryCode</td>
<td>$District</td>
<td>$Population</td>
</tr>";
}
echo "</table>";
if( $page == 0 ){ //user has not yet clicked any link
echo ' Next 10 records ';
}
else if( $page>0 ){ //user has clicked at least once on link
$last = $page - 2; //here -2 because, in isset block again increment by 1
echo '<a href='. $_SERVER['PHP_SELF']. '?page=$last> Last 10 records </a>';
echo '<a href='. $_SERVER['PHP_SELF']. '?page=$page> Next 10 records </a>';
}
else if( $left_rec < $rec_limit ){ //when only records less than 10 remains
$last = $page - 2;
echo '<a href='. $_SERVER['PHP_SELF']. '?page=$last> Last 10 records </a>';
}
?>
if( $page == 0 ){ //user has not yet clicked any link
echo ' Next 10 records ';
}
This will fix your single and double quotes and will echo the values instead of the variables. You have to apply the same logic to all the inputs.
You can also do:
if( $page == 0 ){ //user has not yet clicked any link
echo " Next 10 records ';
}
echo ' Next 10 records ';
And similar $last.
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 |";
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

The first page should be 1 but its -1 and the next page should be 2 but its 0.
How can I make this work? I have tried to edit the $page but when I do, the if/else get wierd.
I added the whole code...
...
$resultt= "SELECT * FROM users WHERE AND country='$okc' AND state='$oks'";
if(!empty($a1) && empty($a2)){
$resultt .= " AND aar>=";
...
}
There are more than 1 if statement.
$result = mysqli_query($con,"$resultt");
$rec_limit = 19;
$row = mysqli_fetch_array($result);
$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);
$resultt .= "LIMIT $offset, $rec_limit";
$sql = $resultt;
$retval = mysqli_query( $con, "$resultt" );
if( $page > 0 )
{
$last = $page - 1;
echo "Last 10 Records |";
echo "Next 10 Records";
}
else if( $page == 0 )
{
echo "Next 10 Records";
}
else if( $left_rec < $rec_limit )
{
$last = $page - 2;
echo "Last 10 Records";
}
while($row = mysqli_fetch_array($retval, MYSQL_ASSOC))
{
}
You should change parts of code to get it to work. $_GET['page'] should give you the queried page number itself, so don't try to manipulate it.
$sql = "SELECT * FROM users WHERE country='$okc' AND state='$oks'"
$rec_limit = 10;
$result = mysqli_query( $con, $sql );
$row = mysqli_fetch_array( $result );
$rec_count = $row[0];
$left_rec = $rec_count - ( $rec_limit * $page );
$page = isset($_GET['page']) ? intval($_GET['page']) : 1;
$offset = $rec_limit * ( $page - 1 ) ;
$sql.= " LIMIT $rec_limit OFFSET $offset";
$result = mysqli_query( $con, $sql );
$row = mysqli_fetch_array( $result );
if( $page > 1 ){
$last = $page - 1;
echo "Last 10 Records |";
echo "Next 10 Records";
}else if( $page == 1 ){
echo "Next 10 Records";
}else if( $left_rec < $rec_limit ){
$last = $page - 2;
echo "Last 10 Records";
}
while( $row = mysqli_fetch_array( $result, MYSQL_ASSOC ) ){
// use $row to echo row contents ...
}
$_GET is an array like your $row.
to access array keys you always use [].
change your get into $_GET['page']
even better:
$page = isset($_GET['page']) ? intval($_GET['page']) : 1;
is page set then convert value to int, because you dont know whats incomming.
if not set take page 1.
btw. constructs like this:
$resultt = "LIMIT $offset, $rec_limit";
can/will cause sql injections bugs within you homepage!
never build a sql with variables!
Use parameters instead!
