Question

我试图过滤我的数据库但是当我这样做时表是空的。我从http://1bestcsharp.blogspot.com/2015/10/php-html-table-search-filter-data-mysql-database.html复制了代码。当我在test_db上尝试他的代码时，它运行良好

这是在过滤之前： https://imgur.com/a/F4J4boM

经过筛选后： https://imgur.com/a/hIFip9s

<?php

 if(isset($_POST['search']))
 {   
$valueToSearch = $_POST['valueToSearch'];
//search in all table columns
//using concat mysql function
$query = "SELECT * FROM pelajar INNER JOIN koko ON pelajar.id = koko.id WHERE 
CONCAT 
('id','nama','umur','kelasid','rsukanid','permainanid','kelabid','ppbid') 
LIKE '%".$valueToSearch."%'";
$search_result = filterTable($query);
}
else{
    $query = "SELECT * FROM pelajar INNER JOIN koko ON pelajar.id = koko.id";
    $search_result = filterTable($query);
}

//function to connect and execute the query
function filterTable($query)
{
$connect = mysqli_connect("localhost", "root", "", "pendaftaran");
$filter_Result = mysqli_query($connect, $query);
return $filter_Result;
}

?>
