I'm trying to show table values from database by using PDO but while doing this it shows an error
"Fatal error: Call to undefined method ManageUsers::fetchAll()"
Please provide solution to solve this?
list-seller.php
<?php
include "C:/wamp/www/Super_Admin_MangoAir/classes/class.ManageUsers.php";
$sellers = new ManageUsers();
//$sellers->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
while ($row = $sellers->fetchAll(PDO::FETCH_ASSOC)) {
?>
<tr>
<td><?php echo $row['company_name']; ?>
<span class="pull-right-container">
<small class="label pull-center bg-green">Premium Member</small>
</span>
</td>
<td><?php echo $row['email']; ?></td>
<td><?php echo $row['mobile']; ?></td>
<td><?php echo $row['count_free']; ?></td>
<td><?php echo $row['count_travel']; ?>
<span class="pull-right-container">
<small class="label pull-center bg-green">Paid</small>
</span>
</td>
<td><button type="button" class="btn btn-flat btn-default btn-sm disabled">Already Paid</button></td>
</tr>
<?php } ?>
class.ManageUsers.php
<?php
class ManageUsers{
include "C:/wamp/www/Super_Admin_MangoAir/classes/class.database.php";
public $link;
function __construct(){
$db_connection = new dbConnection();
$this->link = $db_connection->connect();
return $this->link;
}
function seller_list($result){
$result = $this->link->prepare("SELECT company_name,email,phone,count_free,count_travel FROM login");
$result->execute();
}
}
?>
class.database.php
<?php
class dbConnection{
protected $db_conn;
public $db_name='company';
public $db_user='root';
public $db_pass='';
public $db_host='localhost';
function connect (){
try{
$this->db_conn=new PDO("mysql:host=$this->db_host;dbname=$this->db_name",$this->db_user,
$this->db_pass);
return $this->db_conn;
}
catch(PDOException $e){
return $e->getMessage();
echo 'errorrrrrrrr';
}
}
}
?>

Answer 1

Changes
1) Remove include "C:/wamp/www/Super_Admin_MangoAir/classes/class.database.php"; from class ManageUsers (inside) and place it above.
2) Add public before seller_list().
3) call seller_list() in list-seller.php page.
4) Missed return keyword in function seller_list(). Add it.
5) Remove $result from seller_list() function in Class ManageUsers as it is of no use.
Updated Code
list-seller.php
<?php
include "C:/wamp/www/Super_Admin_MangoAir/classes/class.ManageUsers.php";
$sellers = new ManageUsers();
$query = $sellers->seller_list();
foreach($query as $row){
?>
<tr>
<td><?php echo $row['company_name']; ?>
<span class="pull-right-container">
<small class="label pull-center bg-green">Premium Member</small>
</span>
</td>
<td><?php echo $row['email']; ?></td>
<td><?php echo $row['mobile']; ?></td>
<td><?php echo $row['count_free']; ?></td>
<td><?php echo $row['count_travel']; ?>
<span class="pull-right-container">
<small class="label pull-center bg-green">Paid</small>
</span>
</td>
<td><button type="button" class="btn btn-flat btn-default btn-sm disabled">Already Paid</button></td>
</tr>
<?php } ?>
class.ManageUsers.php
<?php
include "C:/wamp/www/Super_Admin_MangoAir/classes/class.database.php";
class ManageUsers{
public $link;
function __construct(){
$db_connection = new dbConnection();
$this->link = $db_connection->connect();
}
public function getDB(){
return $this->link;
}
public function seller_list(){
$result = $this->getDB()->prepare("SELECT company_name,email,phone,count_free,count_travel FROM login");
$result->execute();
return $result->fetchAll();
}
}
?>

Answer 2

Try to remove return $this->link from your constructor and call fetchAll using $sellers->link->fetchAll(PDO::FETCH_ASSOC)

Answer 3

The constructor of a given class can only return instance of said class, no other return value.
See Constructor returning value?
I'd suggest this instead for your class:
class ManageUsers
{
include "C:/wamp/www/Super_Admin_MangoAir/classes/class.database.php";
private $link;
public function __construct()
{
$db_connection=new dbConnection();
$this->link=$db_connection->connect();
}
public function getLink()
{
return $this->link;
}
And use the last function.
//list-seller.php//
<?php
include "C:/wamp/www/Super_Admin_MangoAir/classes/class.ManageUsers.php";
$manager = new ManageUsers();
$sellers = $manager->getLink();

Answer 4

You need to add a sql query which shows data from table. Try to add these lines in list-seller.php after $sellers = new ManageUsers();:
$sql = 'SHOW TABLES';
$sellers->query($sql);
while ($row = $sellers->fetchAll(PDO::FETCH_ASSOC))
{
