我正在开发一个系统，强制用户（不熟悉wp）在创建新帖子之前选择一个类别，然后添加一些适当的html布局样式来帮助他们。

如果选择类别“x”，则以下代码有效。如何对其进行调整以应对两种不同类别的情况？

所需人员代码：

如果新帖子属于X类：添加此html现有代码-如果类别为“X”，则在新帖子中插入一些html：

// This function will only be called when creating an empty post,
// via `get_default_post_to_edit()`, called in post-new.php
function wpse14403_wp_insert_post( $post_id )
{
    wp_set_post_categories( $post_id, $_REQUEST[\'category_id\'] );
}

add_filter( \'default_content\', \'wpa70073_default_products_content\' );

function wpa70073_default_products_content( $content ) {

    // change this to your desired category ID
    $products_category_id = 4;

    if( 
        isset( $_REQUEST[\'category_id\'][0] )
        && $products_category_id == $_REQUEST[\'category_id\'][0] 
        )
        return \'some html styling\';
}

更新：尝试将此添加到结尾，但不起作用。。。

// change this to your desired category ID

$products_category_id = 4;................

    if( 
        isset( $_REQUEST[\'category_id\'][0] )
        && $products_category_id == $_REQUEST[\'category_id\'][0] 
        )
        return \'Some html styling\';

    if ( $products_category_id = \'6\' ) {
        return \'Some alternative html styling\';
    } else {
        return \'Some default html styling\';
    }
}

还尝试按照下面建议的cpt线程编辑代码，但同样没有成功：(

add_filter( \'default_content\', \'wpa70073_default_products_content\' );
function wpa70073_default_products_content( $content ) {
    switch($content->category){
        // change this to your desired category ID
        case\'4\':
            $content=\'cat 4 content\';
            break;
        case\'6\':
            $content=\'news content\';
            break;
        default:
            $content=\'default content\';
            break;
    }
    return $content;
}

add_filter( \'default_content\', \'wpse_71772_default_content\', 10, 2 );

function wpse_71772_default_content( $content, $post ) 
{
    if( !isset( $_REQUEST[\'category_id\'] ) )
        return $content;

    switch( $_REQUEST[\'category_id\'][0] ){
        // change this to your desired category ID
        case\'1\':
            $content=\'cat 4 content\';
            break;
        case\'3\':
            $content=\'news content\';
            break;
        default:
            $content=\'default content\';
            break;
    }
    return $content;
}
