Theme Options page not saving data correctly

Question

I am struggling to save the correct data in my themes options page. Here is my code in my functions.php file:

<?php 
if ( get_option( 'everes_options' ) ) { 
    $everes_options = get_option( 'everes_options' ); }
else {
    add_option( 'everes_options', array(
        'everes_pdf' => '1', 
        'everes_showBlog' => '1'
    ) );
    $everes_options = get_option( 'everes_options' ); }
}

function everes_options(){
    global $everes_options;
    ?>
    <div class="wrap">
      <h2>Resume Options</h2>
      <form action="edit.php?post_type=employment&page=resume_options" method="post">
        <table>
          <tr>
            <td>Print as PDF?</td>
            <td>
              <select name="everes_pdf">
                <option value="1" <?php selected( '1', $everes_options['everes_pdf'] ); ?> >Yes</option>
                <option value="0" <?php selected( '0', $everes_options['everes_pdf'] ); ?> >No</option>
              </select>
            </td>
          </tr>
          <tr>
            <td>Show blog</td>
            <td>
              <select name="everes_showBlog">
                <option value="1" <?php selected( '1', $everes_options['everes_showBlog'] ); ?> >Yes</option>
                <option value="0" <?php selected( '0', $everes_options['everes_showBlog'] ); ?> >No</option>
              </select>
            </td>
          </tr>
          <tr>
            <td colspan="2"><?php submit_button(); ?></td>
          </tr>
        </table>
      </form>
    </div>
<?php } ?>

When I submit the data, it will save the data, but after a few clicks in the menu, or refreshed in the website, the data disappears. I can't see where the issue is, but I do believe that it would be glaringly obvious to someone here. Any help? Please?

Answer 1

I have found the solution that I was (sort of) looking for. I searched for a video tutorial to integrate my settings with the Theme Customization page, which does pretty much what I wanted it to, and I think might actually be more beneficial there.
