每当我尝试使用下面的PHP脚本插入时,我收到此错误消息发生错误:SQLSTATE [42000]:语法错误或访问冲突:1065查询为空,foreach循环用于处理多个选择值。

你根本不需要从我能看到的东西中进行预测
<?php
require_once("functions/function.php");
require_once("db_connection.php");
require_once("database.php");
if(isset($_POST['group_name'])){
try{
$sql = "INSERT INTO group_details
(group_reg_no, group_name, leader_name,
leader_contact, region, district, division,
ward, village, activity,
category, men, women,
total, registred_date)
VALUES (:group_reg_no, :group_name, :leader_name,
:leader_contact, :region, :district,
:division, :ward, :village, :activity,
:category, :men, :women,
:total, now())";
$statement = $db->prepare($sql);
$params = array(':group_reg_no' => $_POST['group_reg_no'],
':group_name' => $_POST['group_name'],
':leader_name' => $_POST['leader_name'],
':leader_contact' => $_POST['leader_contact'],
':region' => $_POST['region'],
':district' => $_POST['district'],
':division' => $_POST['division'],
':ward' => $_POST['ward'],
':village' => $_POST['village'],
':activity' => $activity,
':category' => $_POST['category'],
':men' => $_POST['men'],
':women' => $_POST['women'],
':total' => $_POST['total'])
foreach ( $_POST['activity'] as $activity ) {
$params[':activity'] = $activity;
$statement->execute();
} // endforeach
$result = "<p style='padding: 20px; color: green;'> Registration Successful</p>";
}
catch (PDOException $ex){
$result = "<p style='padding: 20px; color: red;'> An error occurred: ".$ex->getMessage()."</p>";
}
}
?>
当然,如果您想删除一些不必要的代码,可以删除部分代码并将$_POST
值直接放入$params
数组中。
您还可能希望在执行INSERT之前确保所有$_POST
值isset()
,或者至少使用默认值初始化标量变量。只是为了完全安全。

所以跟进我对课程的评论是我的简化答案:
在您的表单所在的页面上添加以下内容:
<?php
require_once("functions/function.php");
require_once("db_connection.php");
require_once("database.php");
require_once('class.handleit.php');
$handle = new HandleIt();
if (isset($_POST['group_name']))
{
$handle->handleIt($_POST['group_name'], $_POST['group_reg_no'], $_POST['leader_name'], $_POST['leader_contact'], $_POST['region'], $_POST['district'], $_POST['division'],
$_POST['ward'], $_POST['village'], $_POST['activity'], $_POST['category'], $_POST['men'], $_POST['women'], $_POST['total']);
}
?>
让您的生活更轻松。制作class.handleit.php
并添加:
<?php class HandleIt
{
public function handleIt($group, $reg, $leader, $contact, $region, $district, $division, $ward, $village, $activity, $category, $men, $women, $total)
{
$stmt = $this->prepare("INSERT INTO `group_details`(group_reg_no, group_name, leader_name,
leader_contact, region, district, division,
ward, village, activity,
category, men, women,
total, registred_date)
VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?, NOW())");
$stmt->execute([$group, $reg, $leader, $contact, $region, $district, $division, $ward, $village, $activity, $category, $men, $women, $total]);
echo "Success!";
}
public function fetchIt()
{
$stmt = "SELECT * FROM `group_details`";
$res = $this->prepare($stmt);
$res->execute();
while ($row = $res)
{
$rows[] = $row;
}
return $rows;
}
}
你会看到有两个类..插入和获取(插入解释了它的自我和获取是这样你可以在所需的页面上运行你的foreach)。
以下是foreach示例:
<?php
$getForeach = $handle->fetchIt();
foreach ($getForeach as $row)
{
echo "<div>$row->group_name</div>";
/* and so on.. you get the idea.. */
}
?>
请记住,foreach需要进入需要你的班级和班级名称的页面。
