get_search_form 函数在 WordPress 中是用来提取预设的搜索表单或者默认的搜索表单的。因为官方这个函数没有中文的,所以我就简单写了一下。
描述
get_search_form 函数在 WordPress 中是用来提取自定义搜索表单或者默认的搜索表单的。
显示自定义表单还是显示默认表单,完全取决于您的主题中是否有search.php文件,
如果有该文件,则自动调用该文件,如果没有则显示默认的搜索表单。

默认值:true
实例
没你想象的复杂,其实就是这么简单。

<?php get_search_form(); ?> |
这里提一下,如果你需要整合谷歌自定义搜索那些的话,
你只要在你的search.php 文件中将自定义的部分代码放入即可喽,当然你需要设定样式。
