Hi what I'm trying to do is make a pagination for the whole and gives also a chance the user to search for a name and returns a paginated result.
Here is my code
<form method = "POST">
<td>
Search:<input name="search_name" type="text" id="t_searchkey" style="width:35%;" placeholder = "Name">
<input type="submit" name="b_find" id="b_find" title="Find" value = "Find">
</td>
PHP code:
<?php
if(!isset($_POST['b_find']))
{
$query = "SELECT * FROM reginformation
WHERE deleted = 0";
$search_name = "";
}
if(isset($_POST['b_find']))
{
$search_name = trim($_POST['search_name']);
$query = "SELECT * FROM reginformation WHERE name = '$search_name' AND deleted = 0 ";
}
?>
<?php
$result = mysql_query($query) or die(mysql_error());
?>
<?php
$num_rec_per_page=5;
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
if (isset($_GET["search"]))
{
$search_name = $_GET['search'];
}
$start_from = ($page-1) * $num_rec_per_page;
$query2 =$query . " LIMIT $start_from, $num_rec_per_page";
echo "query2 $query2";
$rs_result = mysql_query ($query2); //run the query
while ($row = mysql_fetch_assoc($rs_result)) {
echo "<tr onClick =window.location='infodetailsresp.php?id=$row[regID]'><td>$row[name]</td><td>$row[emailadd]</td><td>$row[contactno]</td><td>$row[event]</td><td>$row[date_register]</td></tr>";
};
//$sql = "SELECT * FROM reginformation";
$rs_result = mysql_query($query); //run the query
$total_records = mysql_num_rows($rs_result); //count number of records
$total_pages = ceil($total_records / $num_rec_per_page);
?>
<?php
echo "<a href='reglistresp.php?page=1&search=$search_name'>".'|< '."</a> "; // Goto 1st page
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='reglistresp.php?page=".$i."&search=$search_name'>". $i ."</a> ";
};
echo "<a href='reglistresp.php?page=$total_pages&search=$search_name'>".' >| '."</a> "; // Goto last page
?>
What happens when I click the next page it gives me the query in the
if(!isset($_POST['b_find']))
So what should be changed so I can get my desired query to the next page?

I used this code in my all pages. Everywhere this code work well. In case of my search page this code count all page by search words but when I click next(2nd or 3rd) page, its cannot display any item. That means sql query for 2nd or 3rd or any others pages not worked. No error also. Pagination page url goes well also.
My Search code:
if(isset($_POST['searchword'])){
$w = mysqli_real_escape_string($dbh, $_POST['searchword']);
$q = strip_tags($w);
$q = trim ($w);
$limit = 12;
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * $limit;
$sql = "SELECT * FROM search_data WHERE MATCH(detail) AGAINST('+$q*' IN BOOLEAN MODE) ORDER BY id ASC LIMIT $start_from, $limit";
$execute = $dbh->query("$sql");
$rowcount = $execute->num_rows ;
if ($rowcount > 0 ) {
$row = $dbh->query($sql) ;
while ($row = $execute->fetch_assoc()) {
$detail = $row['detail'];
$url = $row['url'];
echo $detail;
}
}
}
//Pagination
$sql = "SELECT COUNT(id) FROM search_data WHERE MATCH(detail) AGAINST('+$q*' IN BOOLEAN MODE)";
$result = mysqli_query($dbh,$sql);
$row = mysqli_fetch_row($result);
$total_records = $row[0];
if($total_records > 0){$total_pages = ceil($total_records / $limit); }
$pagLink = "<ul class='pagination'>";
if(!empty($total_pages)){for ($i=1; $i<=$total_pages; $i++) {
$pagLink .= "<li><a href='".$thispage."?page=".$i."'>".$i."</a> </li>";
};
echo $pagLink . "</ul>";
}
Well below i have attached the table structure kindly go through it.
I would like to get serial no as my 1st column followed by id and name. serial no should continue for pagination rather then starting from 1st.
Thanks in advance..
Table structure is
create table departments (
id INT(20) AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30) NOT NULL);
<html>
<head>
<?php
$db_connection = new mysqli("localhost","root","","emp_app");
if($db_connection->connect_error)
die("connection failed".$db_connection->connect_error);
?>
</head>
<body>
<table>
<tr>
<th>Serial no </th>
<th>id</th>
<th>name</th>
</tr>
<?php
$sql_query = "select * from departments";
$result = $db_connection->query($sql_query);
if($result->num_rows > 0){
while($rows = $result->fetch_assoc()){
echo "<tr>";
echo "<td>".$rows["id"]."<td>";
echo "<td>".$rows["name"]."<td>";
echo "<tr>";
}
}
?>
</table>
</body>
here is a good example how to add pagination in php pagination in php
Refrence link is using depricated mysql query you need to replace with mysqli query
$num_rec_per_page=10;
if (isset($_GET["page"])) { $page = $_GET["page"]; } else { $page=1; };
$start_from = ($page-1) * $num_rec_per_page;
$sql = "SELECT * FROM departments LIMIT $start_from, $num_rec_per_page";
$rs_result = $db_connection->query ($sql); //run the query
$serial=1;
while ($row = $result->fetch_assoc) {
//code here
echo $serial;
$serial++;
};
$sql = "SELECT * FROM departments"; //select query for total records
$rs_result = $db_connection->query($sql); //run the query
$total_records =$rs_result->num_rows; //count number of records
$total_pages = ceil($total_records / $num_rec_per_page);
echo "<a href='pagination.php?page=1'>".'|<'."</a> "; // Goto 1st page
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='pagination.php?page=".$i."'>".$i."</a> ";
};
echo "<a href='pagination.php?page=$total_pages'>".'>|'."</a> "; // Goto last page
?>
You could append the URL to add a get variable that will serve as your pagination number i.e. youurl.com/?pagination=1 or 2 or 3
Then in your code add
$pagenumber = $_GET["pagination"];
$offset = $pagenumber * 5; //The number 5 is how many results per page if you wanted 10 results per page this would be 10
Where you have
$sql_query = "select * from departments";
You can change to
$sql_query = "select * from departments" LIMIT 5 OFFSET '$offset';
Which is basically saying; only give me 5 results starting from the pagination row (which is 5 results x page 2 or 3

my default load page is ok with next and prev results.. but for search results i can get only first page then blank for the next page. let say total search results row is 9, it display 3 pages with next link. but when i click the next link, it queries no result on the page 2. here is my code:
echo '<table><tr><td>';
echo '<form method="post" name="frmSearch" action="mypage.php>
Search by name
<input type="text" name="txtSearch">
<input type="submit" name="submit" value="Search">
</form>';
$per_page = 5;
$page = 1;
if (isset($_GET['page']))
{
$page = intval($_GET['page']);
if($page < 1) $page = 1;
}
$start_from = ($page - 1) * $per_page;
$Prev_Page = $page - 1;
$Next_Page = $page + 1;
if (!$_POST){
//$sql = "SELECT * FROM mytable LIMIT $start_from, $per_page";
//$totalr = mysql_query("SELECT COUNT(*) FROM mytable");
//$totalr = mysql_fetch_row($totalr);
//$totalr = $totalr[0];
//$total_pages = $totalr / $per_page;
//$total_pages = ceil($total_pages);
//$listresult = mysql_query($sql);
//$total = mysql_num_rows($listresult);
}
else {
if ($_POST['txtSearch']!="") {$cond1 = " name LIKE
'%".$_POST['txtSearch']."%' ";} else {$cond1 = 1; }
$sql = "SELECT * FROM mytable WHERE ".$cond1." LIMIT $start_from, $per_page";
$totalr = mysql_query("SELECT COUNT(*) FROM mytable WHERE name LIKE
'%".$_POST['txtSearch']."%' ");
$totalr = mysql_fetch_row($totalr);
$totalr = $totalr[0];
$total_pages = $totalr / $per_page;
$total_pages = ceil($total_pages);
$listresult = mysql_query($sql);
$total = mysql_num_rows($listresult);
}
if($total == 0){
echo "<center>No records found.</center>";
}
echo "<span style='float:right;margin-top:8px;'>[ <a href='new.php'>Add New</a>
]</span></td></tr>";
echo "<table>
<tr>
<th>ID</th>
<th>Name</th>
</tr>
";
while ($_POST = mysql_fetch_assoc($listresult)){
echo "<tr>";
echo "<td>" . $_POST['id'] . "</td>";
echo "<td>" . $_POST['name'] . "</td>";
echo "</tr>";
}
echo "</table>";
echo "</table>";
echo $totalr." result";
echo "<br>";
if ($Prev_Page) {
echo " <a href ='{$_SERVER['PHP_SELF']}?page=$Prev_Page'><< Prev</a> ";
}
if ($totalr > $per_page) {
for($i = 1; $i <= $total_pages; ++$i)
{
echo "<a href='{$_SERVER['PHP_SELF']}?page=$i'>$i</a> | ";
}
}
if ($page!=$total_pages) {
echo " <a href='{$_SERVER['PHP_SELF']}?page=$Next_Page'>Next >></a> ";
}
maybe you need to use SELECT COUNT(*) FROM mytable WHERE name LIKE '%$search%' ... remember to escape the $_POST['txtSearch']
<?php
mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("data_wis1") or die(mysql_error());
if(isset($_GET["id"])) {
$id = $_GET["id"];
$sql = "DELETE FROM info WHERE ID = '".$id."'";
mysql_query($sql) or die(mysql_error());
}
if(isset($_GET["page"])) {
$page = $_GET["page"];
}
else {
$page = 1;
}
$start_from = ($page-1) * 1;
$sql = "SELECT * FROM info LIMIT 0, 1";
$query = mysql_query($sql) or die(mysql_error());
?>
<html>
<table>
<?php
for($i = 0; $i <mysql_num_rows($query); $i++) {
$id = mysql_result($query, $i, "ID");
$caseStatus = mysql_result($query, $i, "Case_Status");
echo "<tr>";
echo "<td>".$id."</td>";
echo "<td>".$caseStatus."</td>";
echo "<td><a href='del.php?id=".$id."'><input type='button' value='Delete'></a></td>";
echo "</tr>";
}
?>
</table>
<?php
$sql = "SELECT COUNT(ID) FROM info";
$query = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_row($query);
$total_records = $row[0];
$total_pages = ceil($total_records / 1);
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='del.php?page=".$i."'>".$i."</a> ";
}
?>
</html>
My problem is that whenever i click page 2,3,4... the display doesn't change. Page 2,3,4 gets the display of page 1. It should be like this. For example, page 1 should display ID = 1 and case status = open. Page 2 should display ID = 2 and case status = close and so on.
You never used $start_from in anywhere. I think $sql = "SELECT * FROM info LIMIT '".$start_from."', 1"; is the answer
i am writing code of pagination & i got an error.
this is my code :
<?php
mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("Admin") or die(mysql_error());
if (isset($_GET["page"]))
{
$page = $_GET["page"];
}
else
{
$page=1;
}
$start_from = ($page-1) * 2;
$sql = "SELECT * FROM events ORDER BY event ASC LIMIT $start_from, 2";
$result = mysql_query ($sql) or die(mysql_error());
$num=mysql_numrows($result);
$x=0;
?>
<table>
<tr><td>Event</td><td>Types</td></tr>
<?php
while ($x<$num) {
$row1 = mysql_result($result,$x,'event');
$row2 = mysql_result($result,$x,'types');
?>
<tr>
<td><? echo $row1; ?></td>
<td><? echo $row2; ?></td>
</tr>
<?php
$x++;
}
?>
</table>
<?php
$sql = "SELECT COUNT(event) FROM events";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_row($result);
$total_records = $row[0];
$total_pages = ceil($total_records / 2);
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='pagination.php?page=".$i."'>".$i."</a> ";
}
?>
now i got an error.
object not found
Note that instead of terrible while ($x<$num) you should use way more neat while($row=mysql_fetch_array($res))
so, make it
<?
$per_page = 2;
$page = 1;
if (isset($_GET['page'])) $page = $_GET['page'];
$start_from = ($page-1) * $per_page;
$sql = "SELECT * FROM events ORDER BY event ASC LIMIT $start_from, $per_page";
$res = mysql_query ($sql) or trigger_error(mysql_error().": ".$sql);
?>
<table>
<tr><td>Event</td><td>Types</td></tr>
<?php
while($row=mysql_fetch_array($res)) {
?>
<tr>
<td><? echo $row['event'] ?></td>
<td><? echo $row['types'] ?></td>
</tr>
<?php
}
?>
</table>
<?php
$sql = "SELECT COUNT(event) FROM events";
$res = mysql_query ($sql) or trigger_error(mysql_error().": ".$sql);
$row = mysql_fetch_row($res);
$total_records = $row[0];
$total_pages = ceil($total_records / $per_page);
for ($i=1; $i<=$total_pages; $i++) {
echo "<a href='pagination.php?page=".$i."'>".$i."</a> ";
}
?>
mysql_query returns false - i.e. your query failed and you are passing a wrong argument to mysql_num_rows. I think you have a typo in the table name in the SQL query, it should be events instead. Generally, you should check if the query succeeded:
$result = mysql_query ($sql) or trigger_error(mysql_error().": ".$sql);
