【已解决】wordpress中给Retina主题添加多个菜单

WordPress crifan 786浏览 0评论

【问题】
由于不小心,把之前wordpress中retina的主题更新成最新的0.2版本了,导致原先我手动在0.1的基础上修改的很多代码,使得支持多个菜单,prev和next post,帖子的已读次数等,都丢失了。
所以很是悲剧。然后现在只好一点点手动去重新改写对应的代码,以添加对应的功能。

【解决过程】
下面记录折腾的过程。

1.先是用FileZilla 3.5.3去下载下来对应的retina\lib\structure\menu.php,然后用notepad++打开,结果显示有点问题,每一行都多了一个换行的效果,所以很是悲催。
先不管了,手动删除多余空行,接着按照之前的记忆,去修改对应的代码,改好后,再上传到服务器上,替换原先的menu.php。结果重新打开www.crifan.com,网站却无法显示了,显示500错误。看来是代码添加的有问题了。

2.后来只好去retina的官方网站上面,下载最新的源码,然后找到对应的menu.php,再重新替换回来,然后网站才能正常打开。

3.后来再次重新用notepad++打开menu.php,结果显示又正常了,没了多余的换行了。
然后接着修改代码,去参考这里:
http://www.dayunet.com/WordPress-method-multiple-custom-menu.html

修改后的代码menu.php为:

<?php
/** This theme uses wp_nav_menu() in two locations.*/
register_nav_menus(
	array( 
	'primary-menu' => 'Primary Menu',
	'second-menu' => 'Second Menu',
	)
);

/**
 * Primary Menu
 */

/** Primary Menu Callback */
function retina_primary_menu_cb() {
	wp_page_menu ();		 
}

/** Build Primary Menu */
function retina_primary_menu() {
	
	echo '<div class="menu1">
			<div class="menu1-data">';
	
	if ( has_nav_menu( 'primary-menu' ) ):
	
		$args = array(
			
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'primary-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
						
		);
		
		$args2 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'second-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);
		
		wp_nav_menu( $args );
		wp_nav_menu( $args2 );
	
	else:
	
		retina_primary_menu_cb();
	
	endif;
	
	echo '<div class="clear"></div>
			</div> <!-- end .menu1-data -->
		  </div> <!-- end .menu1 -->';
	
}

/** Primary Menu Init */
add_action( 'retina_after_header', 'retina_primary_menu_init' );
function retina_primary_menu_init() {	
	retina_primary_menu();	
}
?>

然后登陆网站后台管理界面,就可以看到对应的显示效果了:

添加了第二个菜单后的效果

然后就照葫芦画瓢,去添加更多的菜单项。

然后又一共添加了9个,登陆后台管理页面,刷新后,效果如下:

添加了共9个菜单,刷新一下,后台的显示效果

最后共添加了所需要的12个,相关代码如下:

register_nav_menus(
	array( 
	'primary-menu' => 'Primary Menu',
	'second-menu' => 'Second Menu',
	'third-menu' => 'Third Menu',
	'fourth-menu' => 'Fourth Menu',
	'fifth-menu' => 'Fifth Menu',
	'sixth-menu' => 'Sixth Menu',
	'seventh-menu' => 'Seventh Menu',
	'eighth-menu' => 'Eighth Menu',
	'nighth-menu' => 'Nighth Menu',
	'tenth-menu' => 'Tenth Menu',
	'eleventh-menu' => 'Eleventh Menu',
	'twelveth-menu' => 'Twelveth Menu',
	)
);

	if ( has_nav_menu( 'primary-menu' ) ):
	
		$args = array(
			
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'primary-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
						
		);
		
		$args2 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'second-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args3 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'third-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args4 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'fourth-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args5 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'fifth-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args6 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'sixth-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args7 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'seventh-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args8 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'eighth-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args9 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'nighth-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args10 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'tenth-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args11 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'eleventh-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		$args12 = array(
		'container' => 'div', 
		'container_class' => 'primary-container', 
		'theme_location' => 'twelveth-menu',
		'menu_class' => 'sf-menu1',
		'depth' => 0,
		'fallback_cb' => 'retina_primary_menu_cb'
		);

		wp_nav_menu( $args );
		wp_nav_menu( $args2 );
		wp_nav_menu( $args3 );
		wp_nav_menu( $args4 );
		wp_nav_menu( $args5 );
		wp_nav_menu( $args6 );
		wp_nav_menu( $args7 );
		wp_nav_menu( $args8 );
		wp_nav_menu( $args9 );
		wp_nav_menu( $args10 );
		wp_nav_menu( $args11 );
		wp_nav_menu( $args12 );

这12个全部建立好后,把之前就已经存在的菜单(这个是之前就自己建立好的,和主题是脱离的,所以没被覆盖掉),设置好对应关系,

再打开主页,就可以看到主页中的菜单显示效果就是所想要的12个了:

主页中的12个菜单的效果

  对应的之前就创建好的子菜单项目也是存在的
