将快捷码包含在另一个包含的快捷码中会中断输出功能

我已经看到了几个关于这个主题的问题，但似乎没有一个真正回答这个问题。

我当前正在上注册我的短代码after_setup_theme.

function mbe_register_shortcodes() {

    require_once( PATH . \'/inc/shortcodes.php\' );

    add_shortcode( \'font\', \'mbe_shortcode_font\' );

}

add_action( \'after_setup_theme\', \'mbe_register_shortcodes\' );

目录Shortcodes.php:

/**
 * @param array       $attributes
 * @param String|null $content
 *
 * @return string
 */
function mbe_shortcode_font( $attributes = array(), String $content = null ) {

    $default_attributes = array(
        \'color\'  => false,
        \'weight\' => \'normal\',
        \'align\'  => \'left\'
    );

    $attributes = shortcode_atts( $default_attributes, $attributes );

    if ( $attributes[\'color\'] !== false ) {
        $attributes[\'color\'] = \'color\';
    }

    $html = \'\' . PHP_EOL;

    $html .= \'<span class="\' . esc_attr( $attributes[\'color\'] . \' font-\' . $attributes[\'weight\'] . \' text-\' . $attributes[\'align\'] ) . \'">\' . $content . \'</span>\' . PHP_EOL;

    return $html;

}

Sample Text:

[font align="center" weight="extra-bold"]YOUR LOCAL [font color="true"]FULL SERVICE[/font] REAL ESTATE OFFICE[/font]
[font align="center" weight="semi-bold-italic"]Our Realtors Know Real Estate![/font]

With the default code specified above, the output is like:

<span class=" font-extra-bold text-center">YOUR LOCAL [font color="true"]FULL SERVICE</span> REAL ESTATE OFFICE[/font]
<span class=" font-semi-bold-italic text-center">Our Realtors Know Real Estate!</span>

一

[font align="center" weight="extra-bold"]YOUR LOCAL [font color="true"]FULL SERVICE[/font] REAL ESTATE OFFICE[/font]
[font align="center" weight="semi-bold-italic"]Our Realtors Know Real Estate![/font]
#1 I\'ve tried...
$html .= \'<span class="\' . esc_attr( $attributes[\'color\'] . \' font-\' . $attributes[\'weight\'] . \' text-\' . $attributes[\'align\'] ) . \'">\' . $content. \'</span>\' . PHP_EOL;

return do_shortcode( $html );
#1 and outputs...
<span class=" font-extra-bold text-center">YOUR LOCAL 
<span class="color font-normal text-left"></span>
FULL SERVICE</span>
 REAL ESTATE OFFICE[/font]

<span class=" font-semi-bold-italic text-center">Our Realtors Know Real Estate!</span>
#2 And this...
$html .= \'<span class="\' . esc_attr( $attributes[\'color\'] . \' font-\' . $attributes[\'weight\'] . \' text-\' . $attributes[\'align\'] ) . \'">\' . do_shortcode( $content ) . \'</span>\' . PHP_EOL;

return $html;
#2 and outputs...
<span class=" font-extra-bold text-center">YOUR LOCAL 
<span class="color font-normal text-left"></span>
FULL SERVICE</span>
 REAL ESTATE OFFICE[/font]

<span class=" font-semi-bold-italic text-center">Our Realtors Know Real Estate!</span>
#3 And this...
$html .= \'<span class="\' . esc_attr( $attributes[\'color\'] . \' font-\' . $attributes[\'weight\'] . \' text-\' . $attributes[\'align\'] ) . \'">\' . do_shortcode( $content ). \'</span>\' . PHP_EOL;

return do_shortcode( $html );
#3 and outputs ...
<span class=" font-extra-bold text-center">YOUR LOCAL 
<span class="color font-normal text-left"></span>
FULL SERVICE</span>
 REAL ESTATE OFFICE[/font]

<span class=" font-semi-bold-italic text-center">Our Realtors Know Real Estate!</span>

function mbe_register_shortcodes() { require_once( PATH . \'/inc/shortcodes.php\' ); add_shortcode( \'font\', \'mbe_shortcode_font\' ); add_shortcode( \'font_color\', \'mbe_shortcode_font_color\' ); // Added } add_action( \'after_setup_theme\', \'mbe_register_shortcodes\' );

function shortcode_font( $attributes = array(), String $content = null ) { $default_attributes = array( \'weight\' => \'normal\', \'align\' => \'left\' ); $attributes = shortcode_atts( $default_attributes, $attributes ); $html = \'<span class="font-\' . esc_attr( $attributes[\'weight\'] ) . \' text-\' . esc_attr( $attributes[\'align\'] ) . \'">\' . $content . \'</span>\'; return do_shortcode( $html ); } function shortcode_font_color( $attributes = array(), String $content = null ) { $html = \'<span class="color">\' . $content . \'</span>\'; return do_shortcode( $html ); }

ADD_FILTER IMG_CAPTION_SHORTCODE未实现

在我正在创建的插件中，我需要更改[caption]. 我是这样做的（就像《法典》和这里的其他例子一样）add_filter(\'img_caption_shortcode\', \'caption_fix\', 10, 3); function caption_fix ($x, $att, $content) { $content = \'new caption\' ; // change it return $content; } 但是[caption]
