What are common reasons for a PHP "absenden" button not functioning properly?

Common reasons for a PHP "absenden" button not functioning properly include incorrect form action or method, missing name attribute in form elements, or errors in the PHP code handling form submission. To solve this issue, double-check the form action and method, ensure all form elements have a name attribute, and review the PHP code for any syntax errors or logic mistakes. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
    if (isset($_POST['absenden'])) {
        // Handle form submission
    }
}
?>

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>">
    <input type="text" name="input_field">
    <button type="submit" name="absenden">Absenden</button>
</form>
