我的代码存在问题，因为当我按下更新按钮时，我希望它在重定向的页面上仅显示复选框中选中的字段。
我将发布第一页的代码，然后是第二页的代码，更新代码的位置以及网站页面的一些图片。
第一页：
代码首页：
<?php
if (isset ($_POST['search'])){
$ValueToSearch=$_POST['valueToSearch'];
$query1="SELECT * FROM `customer` AS cust,`type` AS type,`valability` AS val WHERE cust.Customer_ID=val.Customer_ID AND val.Insurance_ID=type.Insurance_ID AND CONCAT(cust.Customer_ID,cust.Employee_ID,cust.Name_c,cust.Surname_c,cust.brth,cust.phone,cust.adress,cust.email,type.series,type.type,type.name_i,type.Company_N,type.value,val.nr,val.entry_d,val.exp_d) LIKE '%".$ValueToSearch."%'";
echo "<!-- ". $query1 ." -->";
$search_result=filterTable($query1);
}else{
$query1 = "SELECT * FROM `customer`,`type`,`valability` WHERE customer.Customer_ID=valability.Customer_ID AND valability.Insurance_ID=type.Insurance_ID";
$search_result=filterTable($query1);
}
function filterTable($query1){
$connect=mysqli_connect("localhost" ,"root", "","asig");
$filter_Result=mysqli_query($connect,$query1);
return $filter_Result;
}
?>
<?php
if (isset($_POST['update'])) {
//$connect=mysqli_connect("localhost" ,"root", "","asig");
//$update_id=$_POST['checkbox'];
Header("Location: displayupdate.php");
//die();
//exit;
}else{
echo"can't redirect";
}
?>

答案 0 :(得分：0)
由于您的操作转到了display.php，我会假设您的第二页是＆＃39;是display.php。如果是这种情况，那么您需要使用$ _POST []。
检索提交的检查值在您的示例中，复选框命名为＆＃39;复选框＆＃39;所以你的POST应该如下所示......
<?php
$customer_id_arr = $_POST['checkbox'];
$customer_id_str = implode(",", $customer_id_arr);
//Connect to database
$connect=mysqli_connect("localhost" ,"root", "","asig");
//Select database
mysqli_select_db($connect,'asig');
//Select Query
$sql = "SELECT * FROM `customer`,`type`,`valability` WHERE customer.Customer_ID IN(" . $customer_id_str . ") AND valability.Insurance_ID=type.Insurance_ID";
//Execte query
$records=mysqli_query($connect,$sql);
?>
<html>
您的代码总体上需要一些工作/清理。
希望有所帮助。
