What potential issues can arise when trying to execute multiple actions, such as form submission and link opening, with a single button click in PHP?

When trying to execute multiple actions with a single button click in PHP, potential issues can arise due to the synchronous nature of HTTP requests. To solve this, you can use JavaScript to handle the multiple actions asynchronously, ensuring that each action completes successfully before moving on to the next. 

<!-- HTML form with a button that triggers multiple actions -->
<form method="post" action="">
    <button onclick="executeActions()">Submit Form and Open Link</button>
</form>

<script>
function executeActions() {
    // Submit the form asynchronously
    fetch('process_form.php', {
        method: 'POST',
        body: new FormData(document.querySelector('form'))
    })
    .then(response => {
        if (response.ok) {
            // Open the link after form submission
            window.open('https://example.com', '_blank');
        } else {
            console.error('Form submission failed');
        }
    })
    .catch(error => console.error('Error:', error));
}
</script>
