插入数据的代码。

<form name="reliable-search-form" id="reliable-search-form" method="POST" action="<?php bloginfo(\'url\');?>/search-results/">
<div id="reliable-service"><input type="text" id="search-service" name="search-service" value="<?php wp_dropdown_categories($service); ?>" /></div><!-- #reliable-service -->
<div id="reliable-area"><input type="text" id="search-area" name="search-area" value="<?php wp_dropdown_categories($area); ?>" /></div><!-- #reliable-area -->
<div id="reliable-search-submit-form"><input type="submit" id="reliable-search-submit-button" name="reliable-search-submit-button" value="Search" /></div><!-- #reliable-submit-form -->
</form>

没有任何内容插入到表中。我已经将此代码用于订阅列表，它可以工作，所以我想知道为什么它在这里不工作。
