多个表单和php链接

Question

I have a problem with my form. So in my logandreg.html I have 2 forms. One for login which is

<form method="post" action="valid.php">
  <p>
      Username: 
      <input type="text" name="login_username">
  </p>
  <p>
      Password: 
      <input type="password" name="login_pass">
  </p>
  <div class="clear"></div>
  <div class="form-row login">
      <p>
          <input type="submit" value="Login" id="login" name="login" class="button alt">
      </p>

and another form for register

<form method="post" action="register.php">
  <p>
      Username: 
      <input type="text" name="username">
  </p>
  <p>
      Password: 
      <input type="password" name="pass">
  </p>
  <p>
      E-mail: 
      <input type="text" name="email">
  </p>                      
  <div class="clear"></div>
  <div class="form-row reg">
      <p>
          <input type="submit" data-value="Register" value="Register" id="reg" name="reg" class="button alt">
      </p>

But why when I click on the submit button on the register part it always bring me to valid.php which is from the login form? Both of these form are in the same html. In the valid.php I have this

    <?php
        session_start();
        if(isset($_POST['login']))
        {...}
    ?>

and in the register.php I have this

    <?php
        if(isset($_POST['reg']))
        {...}
    ?>

Why does it always bring me to the valid.php when I click on the register button? Where is my mistake? Thanks

Try to submit both of form using button, and trigger click event then relevent form submit event.

<form name="login" id="login" method="post" action="do_login.php">
    <input type="text" name="inp_1" id="inp_1"/>
    <button type="button" id="login_submit"></button>
</form>

<form name="registration" id="registration" method="post" action="do_registration.php">
    <input type="text" name="inp_2" id="inp_2"/>
    <button type="button" id="registration_submit"></button>
</form>

<script type="text/javascript">
    $("#login_submit").click(function(){
        $("#login").submit();
    });


    $("#registration_submit").click(function(){
        $("#registration").submit();
    });
</script>
