What are some common pitfalls to avoid when implementing multiple actions on a PHP page for form submissions?

One common pitfall to avoid when implementing multiple actions on a PHP page for form submissions is not properly handling the form submission logic for each action. To solve this, you can use a conditional statement to check which action was triggered by the form submission and execute the corresponding code block. 

<?php
// Check if the form was submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Check which action was triggered
    if (isset($_POST['action1'])) {
        // Handle action 1
        // Your code here
    } elseif (isset($_POST['action2'])) {
        // Handle action 2
        // Your code here
    } else {
        // Handle default action or show error message
        // Your code here
    }
}
?>
