Wordpress实现站搜索

wordpress内置的搜索表单如下

<form role="search" method="get" id="searchform" action="<?php echo home_url( ‘/‘ ); ?>">
    <div><label class="screen-reader-text" for="s">Search for:</label>
        <input type="text" value="" name="s" id="s" />
        <input type="submit" id="searchsubmit" value="Search" />
    </div>
</form>

方法一：自定义的函数调用

function my_search_form( $form ) {
    $form = ‘<form role="search" method="get" id="searchform" action="‘ . 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>‘;
    return $form;
}

add_filter( ‘get_search_form‘, ‘my_search_form‘ );

然后在页面相应位置调用：

<?php get_search_form( $echo ); ?>

方法二：模板调用

在模板中创建searchform.php

<form role="search" method="get" id="searchform" action="<?php echo home_url( ‘/‘ ); ?>">
    <div><label class="screen-reader-text" for="s">Search for:</label>
        <input type="text" value="" name="s" id="s" />
        <input type="submit" id="searchsubmit" value="Search" />
    </div>
</form>

然后在页面相应位置调用：

<?php get_template_part(‘searchform‘); ?>
