Question

我的编码不是很好，我需要帮助我的代码。我有一个代码可以在数据库中搜索。现在它显示了数据库中的所有数据，当有人搜索时，它会过滤掉并在同一个表上显示结果。我只想显示结果，当有人在搜索栏上搜索时，它应该显示我过滤的数据。否则，我的桌子应该被隐藏。

任何人都可以告诉我该怎么做。非常感谢你的时间。

  <?php
    if(isset($_POST['search']))
    {
        $valueToSearch = $_POST['valueToSearch'];
        // search in all table columns
        // using concat mysql function
        $query = "SELECT * FROM `ADDRESS` WHERE CONCAT(`ID`, `STATE`) LIKE '%".$valueToSearch."%'";
        $search_result = filterTable($query);

    }
     else {
        $query = "SELECT * FROM `ADDRESS`";
        $search_result = filterTable($query);
    }

    // function to connect and execute the query
    function filterTable($query)
    {
        $connect = mysqli_connect("localhost:3306", "root", "dbadmin", "simplymac");
        $filter_Result = mysqli_query($connect, $query);
        return $filter_Result;
    }

     ?>

您可以使用ajax解决问题。当客户在当时输入文本框时调用一个java脚本函数，在此函数中获取文本框值并为结果表调用ajax。

function getResult(search)
{
	var file_path = '';//your php file path
	$.ajax({
		type: "POST",
		url: file_path,
		data: search,
		cache: false,
		success: function(result){
			//print result in one div
		}
	});
}

 <input type="submit" name="search" value="SEARCH" class="Button" onClick="getResult(this.value);">

如何在搜索栏上隐藏结果表？
