option select form always deleting the sql query

by

Don’t tag your option as selected if you don’t want it selected, which means that you should probably be using selected() to dynamically select any value that has already been set. That should solve the problem.

But this could be cleaned up a lot:

  1. esc_attr() accepts a single parameter. You are sending it two.
  2. It would be easier and cleaner to pull the user meta once and store
    it in a variable.
  3. As mentioned, used selected()

So… 

$statusz = get_the_author_meta( 'statusz', $user->ID ); ?>
<tr class="user-statusz-wrap">
  <th><label for="statusz"><?php _e('Státusz') ?></label></th>
  <td>
    <select type="text" name="statusz" id="statusz">
      <option value disabled selected> -- válassz egyet -- </option>
      <option value="<?php echo esc_attr('Kezdő'); ?>" <?php selected( 'Kezdő', $statusz);?> >Kezdő</option>
      <option value="<?php echo esc_attr('Aktív'); ?>" <?php selected( 'Aktív', $statusz);?>>Aktív</option>
      <option value="<?php echo esc_attr( 'Pártoló'); ?>" <?php selected( 'Pártoló', $statusz);?>>Pártoló</option>
    </select>
    </td>
</tr>
