get_search_form 函數在 WordPress 中是用來提取預設的搜索表單或者默認的搜索表單的。因為官方這個函數沒有中文的，所以我就簡單寫了一下。

描述

get_search_form 函數在 WordPress 中是用來提取自定義搜索表單或者默認的搜索表單的。

顯示自定義表單還是顯示默認表單，完全取決于您的主題中是否有search.php文件，

如果有該文件，則自動調用該文件，如果沒有則顯示默認的搜索表單。

使用

<?php

get_search_form($echo = true)

?>

參數

$echo 布爾型，用來選擇顯示還是返回變量。

默認值：true

實例

沒你想象的復雜，其實就是這么簡單。

<?php

get_search_form();

?>

這里提一下，如果你需要整合谷歌自定義搜索那些的話，

你只要在你的search.php 文件中將自定義的部分代碼放入即可嘍，當然你需要設定樣式。

函數源代碼

<?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);
