如何在链接编辑器现有的“链接关系(XFN)选项”列表中添加“noollow”选项？

时间：2010-12-10 作者：Scott B

将“nofollow”选项添加到链接编辑器现有的“链接关系（XFN）选项列表”有多困难？

或者，或者更好的是，另外，在“批量操作”列表中添加一个名为“使链接不跟随”的项目，该项目将使所有选定的链接rel=“nofollow”。

我想将此功能添加到我的主题功能中。php

或者，您可以通过将队列重新指向xfn来撤消禁用关系框的代码。js脚本。。

首先创建该脚本的修改版本，如下所示。。

jQuery(document).ready( function($) {
    //$(\'#link_rel\').attr(\'readonly\', \'readonly\');
    $(\'#linkxfndiv input\').bind(\'click keyup\', function() {
        var isMe = $(\'#me\').is(\':checked\'), inputs = \'\';
        $(\'input.valinp\').each( function() {
            if (isMe) {
                $(this).attr(\'disabled\', \'disabled\').parent().addClass(\'disabled\');
            } else {
                $(this).removeAttr(\'disabled\').parent().removeClass(\'disabled\');
                if ( $(this).is(\':checked\') && $(this).val() != \'\')
                    inputs += $(this).val() + \' \';
            }
        });
        $(\'#link_rel\').val( (isMe) ? \'me\' : inputs.substr(0,inputs.length - 1) );
    });
});
另存为xfn.js 并放入插件文件夹或当前主题文件夹。

NOTE: 这是WordPress排队的原始（现有）脚本的直接副本，我留下了将rel输入设置为只读的原始代码，以便您可以查看更改的内容（一行）。

然后将其添加到插件代码或主题函数中。，并取消对代码示例中相应行的注释。。

function switch_xfn_src( $src, $handle ) {
    if( \'xfn\' == $handle )
        //$src = plugins_url( \'/xfn.js\', __FILE__ ); // For use inside plugin
        //$src = get_bloginfo( \'stylesheet_directory\' ) . \'/xfn.js\'; // For use inside theme
    return $src;
}
add_filter( \'script_loader_src\', \'switch_xfn_src\', 10, 2 );
工作完成了……：）

我不确定是否存在过滤器或操作。如果是这样的话，就相当容易了。如果没有，请使用我的外部链接插件：

这里有一个函数，它删除了现有的link\\u xfn元框，并添加了另一个相同的元框，其中带有“nofollow”复选框：

add_action( \'admin_menu\', \'nofollow_enabled_xfn_box\' );

function nofollow_enabled_xfn_box() {
    global $pagenow;
    if ( $pagenow != \'link.php\' ) return;

    remove_meta_box( \'linkxfndiv\', \'link\', \'normal\' );
    add_meta_box(\'linkxfndiv\', __(\'Link Relationship (XFN)\'), \'se5160_link_xfn_meta_box\', \'link\', \'normal\' );
}

/**
 * Modified xfn form fields box, with "nofollow" link.
 *
 * @based on function link_xfn_meta_box() (from /wp-admin/includes/meta-boxes.php)
 *
 * @param object $link

很多core的copypasta，但它比黑客好。当然，您可以任意更改xfn选项。

它已经在里面了。您只需在浏览器中停用javascript并重新加载页面。您现在可以自由进入nofollow.
