在使用php/javascript或jquery提交form1时，停止提交其他form2
在使用php/javascript或jquery提交form1时，停止提交其他form2
提问于 2021-09-09 15:25:48
这是我正在做的真实代码，第一篇文章包含了同样的问题，
如您所见，Form1按钮用于控制我在此表单中使用的会话的$_SESSION‘’clicks‘值的迭代，
Form2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form2中单击按钮或在php中调出按钮时，另一个表单或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'],
];
}
?>

嗨，我想我明白你想说什么了。
只需用以下代码包装表单中的逻辑即可：
<?php
if(isset($_POST['btn1'])) {
//Code for form 1
}
if(isset($_POST['btn2'])) {
//Code for form 2

很抱歉打扰你们，我找到我的错误了。正是会话‘’click‘的if else触发了导致提交所述form1的事件。并感谢您的建议，使我的代码更简短！
<?php
include 'connection.php';
session_start();
$results_per_page = 10;

}
$stmt1 = $conn->prepare("SELECT*FROM doctors");
$stmt1->execute();
$stmt2 = $conn->prepare("SELECT*FROM doctors ORDER BY doctor_name ASC");
$stmt2->execute();
