get_search_form

评论(1)

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。

使用

<?php
    get_search_form($echo = true) 
?>

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。

<?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。

函数源代码

<?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 = '<form role="search" method="get" id="searchform" action="' . esc_url( home_url( '/' ) ) . '" >
	<div><label class="screen-reader-text" for="s">' . __('Search for:') . '</label>
	<input type="text" value="' . get_search_query() . '" name="s" id="s" />
	<input type="submit" id="searchsubmit" value="'. esc_attr__('Search') .'" />
	</div>
	</form>';
 
	if ( $echo )
		echo apply_filters('get_search_form', $form);
	else
		return apply_filters('get_search_form', $form);
}
?>

总结

NONE
假期过得真快。

  1. 楼主:应该是寻找searchform.php吧,search.php这个文件是显示搜索结果的模板。
