isset condition for different submit button

Question

I have two submit button in my webpage. Once a button is clicked (using post method), it will do perform different action.

How do I check which of the two button is clicked by the user?

The code for the two button

<form name="existingForm" method="post" action="">
     <div class="alert alert-info" role="alert" style="text-align: center;">
          <label>Are you a returning customer?</label>
          <input name="button1" type="submit" value="Login Here" />
     </div>
</form>

<form name="logingForm" method="post" action="">
     <div class="alert alert-info" role="alert" style="text-align: center;">
          <label>Are you a returning customer?</label>
          <input name="button2" type="submit" value="Login Here" />
     </div>
</form>

The code for post method for button 1:

if($_SERVER["REQUEST_METHOD"] == "POST")
    {
        $buttonPressed = 1;
    }

The code for post method for button 2:

if($_SERVER["REQUEST_METHOD"] == "POST")
    {
        $buttonPressed -= 1;
    }

Why don't you check if the respective button is pressed or not and then do your stuff? Something like:

<?php
if(isset($_POST['button1']))
{
// your stuff for existingForm
}
else 
if(isset($_POST['button2']))
{
// your stuff for logingForm
}

<form name="existingForm" method="post" action="">
     <div class="alert alert-info" role="alert" style="text-align: center;">
          <label>Are you a returning customer?</label>
          <input name="button1" type="submit" value="Login Here" />
     </div>
</form>

<form name="logingForm" method="post" action="">
     <div class="alert alert-info" role="alert" style="text-align: center;">
          <label>Are you a returning customer?</label>
          <input name="button2" type="submit" value="Login Here" />
     </div>
</form>
