How can PHP developers effectively debug issues with checkbox values not being transmitted?

Issue: If checkbox values are not being transmitted in PHP, it could be due to the checkboxes not being properly named in the HTML form or not being checked before submitting the form. To solve this, ensure that each checkbox has a unique name attribute and that they are checked before submitting the form. 

// Example HTML form with checkboxes
<form method="post" action="process_form.php">
    <input type="checkbox" name="checkbox1" value="1"> Checkbox 1
    <input type="checkbox" name="checkbox2" value="2"> Checkbox 2
    <input type="submit" value="Submit">
</form>

// process_form.php
<?php
if(isset($_POST['checkbox1'])) {
    $checkbox1_value = $_POST['checkbox1'];
    // Process checkbox1 value
}

if(isset($_POST['checkbox2'])) {
    $checkbox2_value = $_POST['checkbox2'];
    // Process checkbox2 value
}
?>
