将 WordPress 标题设置为两个单独的变量

Question

我有一个自定义的 post 类型，其中有一堆 post 的格式都像这样

 Artist - Song Title

例如

The Smashing Pumpkins - Quiet

我试图将 'Artist' 放入变量 $artist 并将 'Song Title' 放入变量 $song

 $artistsong = get_the_title();
 $songeach = explode("-", $artistsong);
 $artist = $songeach[0];
 $song = $songeach[1];

但这不起作用。 Echo-ing $artist 获得完整标题

The Smashing Pumpkins - Quiet

回显 $song 不输出任何内容

如果我只是从纯文本开始，这有效，但不适用于 'get_the_title()'

 $song = "The Smashing Pumpkins - Quiet";
 $songeach = explode("-", $song);
 $artist = trim($songeach[0]);
 $song = trim($songeach[1]);
 echo $artist;
         //echos 'The Smashing Pumpkins'
 echo $song;
         //echos 'Quiet'

除了 get_the_title() 之外，还有其他方法可以将完整标题放入最初的变量中，这似乎对我不起作用，还是我遗漏了其他东西？

Answer 1

将此代码添加到您的 functions.php

function get_the_title_keep_hyphen( $post = 0 ) {
    $post = get_post( $post );

    $title = isset( $post->post_title ) ? $post->post_title : '';
    $id = isset( $post->ID ) ? $post->ID : 0;

    if ( ! is_admin() ) {
        if ( ! empty( $post->post_password ) ) {

            /**
             * Filter the text prepended to the post title for protected posts.
             *
             * The filter is only applied on the front end.
             *
             * @since 2.8.0
             *
             * @param string  $prepend Text displayed before the post title.
             *                         Default 'Protected: %s'.
             * @param WP_Post $post    Current post object.
             */
            $protected_title_format = apply_filters( 'protected_title_format', __( 'Protected: %s' ), $post );
            $title = sprintf( $protected_title_format, $title );
        } elseif ( isset( $post->post_status ) && 'private' == $post->post_status ) {

            /**
             * Filter the text prepended to the post title of private posts.
             *
             * The filter is only applied on the front end.
             *
             * @since 2.8.0
             *
             * @param string  $prepend Text displayed before the post title.
             *                         Default 'Private: %s'.
             * @param WP_Post $post    Current post object.
             */
            $private_title_format = apply_filters( 'private_title_format', __( 'Private: %s' ), $post );
            $title = sprintf( $private_title_format, $title );
        }
    }

    /**
     * Filter the post title.
     *
     * @since 0.71
     *
     * @param string $title The post title.
     * @param int    $id    The post ID.
     */
    return $title;
}

并在您的 single.php

中使用此代码

$artistsong = get_the_title_keep_hyphen();
$songeach = explode(" - ", $artistsong);
$artist = $songeach[0];
$song = $songeach[1];

看到最后一行

我从return apply_filters( 'the_title', $title, $id );变成了return $title;

因为 apply_filters 函数将连字符从 - => –.

Answer 2

这是因为破折号。

试试 $songeach = explode("P", $artistsong); 你就会明白我的意思了。您可以尝试在艺术家和歌曲名称之间使用不同的字符 - 虽然可能不理想。
