在目录视图中从rsform回显特定字段

Question

我在积极使用该网站多年后的第一篇文章。

我正在尝试通过公司内部网站点上的RSFORM设置目录视图。一切都已完成，但在目录视图中我想回显表单中一个选择器的值（选择器隐藏在表单中，并在编辑中可见）。因此，当您在表单提交后编辑此选择器时，它会将此值回显到目录的特定区域（将其添加到整行的类）。

但我无法弄清楚如何获得特定的字段值..

我试过这个

echo $this->$field(FIELD_NAME); 

代码部分就像这样

    <?php if ($this->items) { ?>
    <?php foreach ($this->items as $i => $item) { ?>
    <tr class="row<?php echo $i % 2; ?> directoryRow **<?php echo $this->$field(FIELD_NAME);  ?>**">
        <?php if ($this->directory->enablecsv) { ?>
            <td align="center" class="center directoryGrid"><?php echo JHtml::_('grid.id', $i, $item->SubmissionId); ?></td>
        <?php } ?>
        <?php foreach ($this->viewableFields as $field) { ?>
            <td align="center" class="center directoryCol directoryCol<?php echo $this->getFilteredName($field->FieldName); ?>"><?php echo $this->getValue($item, $field); ?></td>
        <?php } ?>

这是来自view.html.php文件
