大家好！我需要你的帮助。我的代码出错，我的编译器说mysq_query（）expert参数1是字符串，资源给定test.php第21行和mysql_fetch_array（）期望参数1是资源，在第72行的test.php中给出null 我无法弄清楚如何解决这个错误，我不知道如何在我的代码上添加分页，我想知道如果过滤器没有结果我怎么能显示任何消息。 。请查看并查看下面的代码。预先感谢您的帮助。 :)
这是我的代码：
Hi everyone!, I need your help. I got an error in code, my compiler said "mysq_query() experts parameter 1 to be string, resource given test.php line 21" and "mysql_fetch_array() expects parameter 1 to be resource, null given in test.php on line 72" and I can't figure out how to solve this errors and I don't know how I will add pagination on my codes and I would like to know how I can show any message when there is no result from the filters. . Please see and check my codes below. Thank you in advance for your help. :)
Here is my codes:
<?php
if(isset($_POST['search']))
{
$valueToSearch = $_POST['valueToSearch'];
// search in all table columns
// using concat mysql function
$query = "SELECT * FROM `dbcharity2016` WHERE CONCAT(`genNo`, `reliefNo`, `disas_date`, `area`, `city`, `type`, `surv_date`, `surv_date`, `surv_volunteers`, `vol_incharge`, `relief_date`, `volunteers`, `venue`, `T_Beneficiary`, `unit`, `individual`, `house`, `sacksNo`, `DRG`, `cost_set`, `cost_relief`, `DAI`, `CAG`, `TCA`) LIKE '%".$valueToSearch."%'";
$search_result = filterTable($query);
}
else {
$query = "SELECT * FROM `dbcharity2016`";
$search_result = filterTable($query);
}
// function to connect and execute the query
function filterTable($query)
{
$con = mysql_connect("localhost","test_webdev","e7#_AZ*9we_^","test_WebBase");
$filter_Result = mysql_query($con, $query);
return $filter_Result;
}
?>

我尝试过：
我试图将$连接更改为$ con，将mysqli_query更改为mysql_query，遗憾的是错误仍然存在并且增加了更多。我不知道如何修复这个混乱以及如何在每个页面中添加分页时，当表格自动打10行时，将出现分页。我也知道当没有结果过滤器时如何显示消息无结果。
[由Nelek编辑]从非答案复制的其他信息下面
我使用的是php 4.0.1和Mysql版本5.5.54
What I have tried:
I tried to change $connection to $con and mysqli_query to mysql_query, unfortunately the error is still there and increased more. I don't know how I fix this mess and how I add pagination too in every page when table hit 10 rows automatic the pagination will appeared. and I know too how to show message "No Result" when there is no result in filter.

推荐答案
_POST ['search '）））
{
_POST['search'])) {
valueToSearch =
valueToSearch =
_POST ['valueToSearch'];
//在所有表格列中搜索
//使用concat mysql函数
_POST['valueToSearch']; // search in all table columns // using concat mysql function
