What are common reasons for input values not being transferred via $_POST in PHP forms, and how can they be resolved?

Common reasons for input values not being transferred via $_POST in PHP forms include incorrect form method (e.g., using GET instead of POST), missing name attribute in form inputs, or issues with form submission (e.g., missing submit button or JavaScript validation preventing form submission). To resolve these issues, ensure that the form method is set to POST, all form inputs have a name attribute, and any JavaScript validation allows the form to be submitted. 

<form method="post" action="">
    <input type="text" name="username">
    <input type="password" name="password">
    <input type="submit" value="Submit">
</form>
