如何添加footer模块到wordpress主题？
1、第一步，点击WP后台的Appearance Menu > Editor，编辑functions.php，添加以下代码并保存：
register_sidebar(array(
'name' => 'Footer Widget 1',
'id' => 'footer-1',
'description' => 'First footer widget area',
'before_widget' => '<div id="footer-widget1">',
'after_widget' => '</div>',
'before_title' => '<h2>',
'after_title' => '</h2>',
));
register_sidebar(array(
'name' => 'Footer Widget 2',
'id' => 'footer-2',
'description' => 'Second footer widget area',
'before_widget' => '<div id="footer-widget2">',
'after_widget' => '</div>',
'before_title' => '<h2>',
'after_title' => '</h2>',
));
register_sidebar(array(
'name' => 'Footer Widget 3',
'id' => 'footer-3',
'description' => 'Third footer widget area',
'before_widget' => '<div id="footer-widget3">',
'after_widget' => '</div>',
'before_title' => '<h2>',
'after_title' => '</h2>',
));
2、第二步，编辑footer.php，添加以下代码并保存：
<div id="footer-widgets">
<div id="footer-widget1">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('footer-1') ) : ?>
<?php endif; ?>
</div>
<div id="footer-widget2">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('footer-2') ) : ?>
<?php endif; ?>
</div>
<div id="footer-widget3">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar('footer-3') ) : ?>
<?php endif; ?>
</div>
</div>
<div style="clear-both"></div>
3、第三步，编辑style.css，为这个模块设置相应样式，添加以下代码并保存（可根据自己网站情况修改css）：
#footer-widgets {
display: block;
width:950px;
margin-right:0;
background: #ffffff;
}
#footer-widget1 {
width: 260px;
float: left;
margin: 15px 10px 10px 30px;
padding: 10px;
background-color: #ffffff;
}
#footer-widget2 {
width: 260px;
float: left;
margin: 15px 10px 10px 15px;
padding: 10px;
background-color: #ffffff;
}
#footer-widget3 {
width: 260px;
float: left;
margin: 15px 10px 10px 15px;
padding: 10px;
background-color: #ffffff;
}
