表单需要在PHP中处理两个提交按钮

问题描述：

In my HTML I have a form where users can register or login.The problem is both Register and Login buttons are in the same form, and they are handled by two scripts: register.php and login.php.

<form action=" ">

there could just be one script name. So how to make the form able to handle two submit buttons(two scripts)?

  <form action="register.php" method="post" class="login_form">     

    <div class="login_form_input_container">   
      <label for="email" class="login_form_label">Email</label>
      <input type="email" id="email" name="email" class="login_form_input">
    </div>

    <div class="login_form_input_container">  
      <label for="password" class="login_form_label">Password</label>
      <input type="password" id="password" name="password" class="login_form_input">
    </div>

    <a href="forgot_password/" class="forgot_password_link">Forgot password?</a>

    <input type="submit" id="login_submit" name="login_submit" value="Log In" class="login_form_submit">

    <input type="submit" id="register_submit" name="register_submit" value="Register" class="login_form_submit">

  </form>

在我的HTML中，我有一个用户可以注册或登录的表单。问题是注册和登录按钮都在相同的表单，它们由两个脚本处理：register.php和login.php。 p>

在 p>

 ＆lt; form action =“”＆gt;  
  code>  pre> 
 
 可能只有一个脚本名称。 那么如何使表单能够处理两个提交按钮（两个脚本）？ p> 
 
 
 ＆lt; form action =“register.php”method =“post”class =“login_form  “＆GT;  
 
＆lt; div class =“login_form_input_container”＆gt;  
＆lt; label for =“email”class =“login_form_label”＆gt;电子邮件＆lt; / label＆gt; 
＆lt; input type =“email”id =“email”name =“email”class =“login_form_input”＆gt; \  n＆lt; / div＆gt; 
 
＆lt; div class =“login_form_input_container”＆gt;  
＆lt; label for =“password”class =“login_form_label”＆gt;密码＆lt; / label＆gt; 
＆lt; input type =“password”id =“password”name =“password”class =“login_form_input”＆gt; \  n＆lt; / div＆gt; 
 
＆lt; a href =“forgot_password /”class =“forgot_password_link”＆gt;忘记密码？＆lt; / a＆gt; 
 
＆lt; input type =“submit”id =“login_submit  “name =”login_submit“value =”登录“class =”login_form_submit“＆gt; 
 
＆lt; input type =”submit“id =”register_submit“name =”register_submit“value =”Register“class =”login_form_submit  “＆gt; 
 
＆lt; / form＆gt; 
  code>  pre> 
  div>

答

Create another script register_or_login.php, let that script handle the form submission and make it route to either the login or register backend script:

if (isset($_POST['login_submit'])) {
    require 'login.php';
} elseif (isset($_POST['register_submit'])) {
    require 'register.php';
}

A button is not much different from, say, a checkbox or textfield; if you give it a name it will be present in $_POST.

答

you can just check with isset which one was sent/clicked like so

if(isset($_POST['login_submit'])){
    //do login
}elseif(isset($_POST['register_submit'])){
    //do register
}

I just thought of this and checked that if a user just hits enter without clicking a submit button it sends the first submit name/value as a default. So in your case login_submit will be sent if user just hits enter which is probably a good thing.
