使用 php/javascript 或 jquery 提交 form2 时阻止其他 form1 提交

【中文标题】使用 php/javascript 或 jquery 提交 form2 时阻止其他 form1 提交【英文标题】：stop other form1 from submitting when submitting form2 using php/javascript or jquery 【发布时间】：2021-11-06 06:44:04 【问题描述】：这是我正在做的真正代码 第一篇文章包含同样的问题，
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;

$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'],

【问题讨论】：
你所说的听起来不正确。您可以在页面中拥有任意数量的表单，但用户一次只能提交一个。提交一份表格不会导致提交另一份表格。唯一的例外是，如果您专门编写了一些导致这种情况发生的 javascript 代码……您这样做了吗？ 对不起，我更新了我的帖子，你能看一下吗？ 【参考方案1】：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
【讨论】：
虽然你最终可能是对的，但这有点投机。我们不确定 PHP 如何处理表单，以及这是否导致了 OP 所看到的任何内容（不清楚，因为它们的描述似乎在谈论一些不可能的事情）。最好提供依赖于问题信息而不是猜测的答案。获得 50 名代表，发表评论要求澄清，关注问题，然后在确定具体问题后回答。 是的，我正在使用会话，这会影响其他表单的性能吗？ @MelvinEsguerra 之前没有提到会话......而且我的 sn-p 与会话无关......顺便说一下，你熟悉循环（for、foreach、while）不需要所有这些回声，您只需关闭 php 标签写入 html 并重新打开 php 标签。输入名称也可以是数组，所以你不会有 sa1 ... sa10... @edluis97 抱歉，如果您认为我在“展示我的代表”，但实际上不是，我只是想在网站上保持高质量的答案。与个人无关 ：-）。我没有说你不能帮忙。但是......过于依赖猜测/假设的答案通常最终会成为无益的分心。在***，我们更愿意尽可能根据可用的事实来回答。如果事实不可用，请要求澄清。 50 rep 是 5 upvotes，所以这不是一个漫长的旅程，即使你不能给太多时间。我不会在这里花太多时间，我只是在这里待了一段时间！【参考方案2】：很抱歉打扰你们，我发现我的错误。是 session['click'] 的 if else 触发了导致上述 form1 被提交的事件。并感谢您让我的代码更短的建议！

不客气，@Melvin。很抱歉，我无法提供更多帮助。祝你在这条漫长（真的很长）的道路上好运。继续练习，尽量不要太不知所措。一步一步走很长的路。 非常感谢！我会记住这一点以上是关于使用 php/javascript 或 jquery 提交 form2 时阻止其他 form1 提交的主要内容，如果未能解决你的问题，请参考以下文章
