下拉列表对用户禁用，仅对管理员工作正常，但是当我编辑页面并重新提交时，它会在DB中将特定列留空。

<select class="form-control"  name="currency[]" <?php if($_SESSION['info'] == staff){ echo 'disabled="true"'; } ?>>
                                <option value="INR"<?php if ($row[currency] == 'Rs') echo ' selected="selected"'; ?>>Indian Rupee</option>
                                <option value="USD"<?php if ($row[currency] == 'USD') echo ' selected="selected"'; ?>>US Dollar</option>
                                <option value="CNY"<?php if ($row[currency] == 'cny') echo ' selected="selected"'; ?>>Chinese Yuan</option>
