How can the issue of select fields being outside the form be resolved in PHP?

Issue: The problem of select fields being outside the form can be resolved by ensuring that the select fields are placed within the form tags in the HTML code. This ensures that the selected values are included in the form submission data.

<form action="process_form.php" method="post">
    <label for="select_field">Select Option:</label>
    <select name="select_field" id="select_field">
        <option value="option1">Option 1</option>
        <option value="option2">Option 2</option>
        <option value="option3">Option 3</option>
    </select>
    <input type="submit" value="Submit">
</form>
