Question

我有一个项目，我现在正在做，我的项目由CRUD功能组成，它工作正常。我的项目也有分页和搜索功能。

分页正在运行，但搜索功能似乎不起作用。我想要的是一个搜索，我可以搜索我的表格中的任何内容，就像我想要搜索所有字段或者可能是实时搜索一样。有人可以帮助我。

Dbconfig.php

<?php
$db_host = 'localhost'
$db_username = 'root';
$db_password = '';
$db_name = 'survey';

try{
$db_con = new PDO("mysql:host={$db_host};dbname={$dbname}",db_username,$db_password);
}
catch(PDOException $exception{
echo $exception->getMessage();
}
include_once 'class.paginate.php'
$paginate = new paginate($DB_con);
?>

Class.paging.php

<?php
class paginate{
    private $db;

    function __construct($DB_con)
    {
     $this->db = $DB_con;
     }

     public function dataview($query)
    {
     $stmt = $this->db->prepare($query);
     $stmt->execute();

     if($stmt->rowCount()>0)
     {
            while($row=$stmt->fetch(PDO::FETCH_ASSOC))
            {
               ?>
               <tr>
               <td><?php echo $row['user_id']; ?></td>
               <td><?php echo $row['username']; ?></td>
               <td><?php echo $row['password']; ?></td>

               </tr>
               <?php
