javascript - 使用 php/javascript 或 jquery 提交 form2 时阻止其他 form1 提交
问题描述
这是我正在做的第一篇文章的真实代码包含同样的问题，
如您所见，表单 1 按钮用于控制 $_SESSION['clicks'] 值的迭代，我在此表单中使用会话，
表单 2 按钮用于回显从另一个数组中检索到的对应名称的数组。
问题是每次在 php 中单击或调用 form2 中的按钮时，其他表单或 form1 也会被提交
<?php
session_start();
$results_per_page = 10;
if (!isset($_GET['page'])) {
$page = 1;
}else{
$page = $_GET['page'];
}
$stmt1 = $conn->prepare("SELECT*FROM doctors");
$stmt1->execute();
$stmt2 = $conn->prepare("SELECT*FROM doctors ORDER BY doctor_name ASC");
$stmt2->execute();
while($row = $stmt2->fetch()) {
$result[] = [
'name' => $row['doctor_name'],
'degree' => $row['doctor_degree'],
'foe' => $row['doctor_foe'],
];
}

解决方案
嗨，我想我明白你想说什么。
只需使用以下内容包装表单中的逻辑：
<?php
if(isset($_POST['btn1'])) {
//Code for form 1
}
if(isset($_POST['btn2'])) {
//Code for form 2
}
