WordPress中用于获取搜索表单的PHP函数使用解析

前端之家收集整理的这篇文章主要介绍了WordPress中用于获取搜索表单的PHP函数使用解析前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

get_search_form 函数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,则自动调用文件,如果没有则显示默认的搜索表单。

使用

PHP;">

参数

$echo 布尔型,用来选择显示还是返回变量。 默认值:true

实例

没你想象的复杂,其实就是这么简单。

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。

函数代码

PHP;"> PHP /** * Display search form. * * Will first attempt to locate the searchform.PHP file in either the child or * the parent,then load it. If it doesn't exist,then the default search form * will be displayed. The default search form is HTML,which will be displayed. * There is a filter applied to the search form HTML in order to edit or replace * it. The filter is 'get_search_form'. * * This function is primarily used by themes which want to hardcode the search * form into the sidebar and also by the search widget in wordpress. * * There is also an action that is called whenever the function is run called,* 'get_search_form'. This can be useful for outputting JavaScript that the * search relies on or varIoUs formatting that applies to the beginning of the * search. To give a few examples of what it can be used for. * * @since 2.7.0 * @param boolean $echo Default to echo and not return the form. */ function get_search_form($echo = true) { do_action( 'get_search_form' );

$search_form_template = locate_template('searchform.PHP');
if ( '' != $search_form_template ) {
require($search_form_template);
return;
}

$form = '

';

if ( $echo )
echo apply_filters('get_search_form',$form);
else
return apply_filters('get_search_form',$form);
}
?>
