如何在WP 3.9中自定义TinyMCE4-样式和格式的旧方法不再起作用

在WP 3.9之前，我在function.php中应用了以下两个过滤器：

function my_mce_buttons_2( $buttons ) {
    array_unshift( $buttons, 'styleselect' );
    return $buttons;
}
add_filter('mce_buttons_2', 'my_mce_buttons_2');

function mce_mod( $init ) {
    $init['theme_advanced_blockformats'] = 'p,h3,h4';
    $init['theme_advanced_styles'] = "Header gross=mus-bi news-single-bighead; Header klein=mus-bi news-single-smallhead; Link=news-single-link; List Items=news-single-list";
    return $init;
}
add_filter('tiny_mce_before_init', 'mce_mod');

因此，段落格式下拉列表仅显示p，h3和h4，而自定义样式下拉列表显示“ Header gross”，“ Header klein”等。但是不幸的是，wp和tinymce从wp 3.9开始就不再麻烦了，我现在仅看到标准段落格式的下拉列表

以及标准样式格式下拉列表：

到目前为止，我还没有找到关于文档更新到tinymce 4时是否有任何钩子的文档。有人知道吗？最好的问候拉尔夫

更新：基于更多的研究和下面的评论，我想我已经知道了：

//Creating the style selector stayed the same
function my_mce_buttons( $buttons ) {
   array_unshift( $buttons, 'styleselect' );
   return $buttons;
}
add_filter('mce_buttons', 'my_mce_buttons');

function mce_mod( $init ) {
   //theme_advanced_blockformats seems deprecated - instead the hook from Helgas post did the trick
   $init['block_formats'] = "Paragraph=p; Heading 3=h3; Heading 4=h4";

   //$init['style_formats']  doesn't work - instead you have to use tinymce style selectors
   $style_formats = array(
    array(
        'title' => 'Header 3',
        'classes' => 'mus-bi news-single-bighead'
    ),
    array(
        'title' => 'Header 4',
        'classes' => 'mus-bi news-single-smallhead'
    ),
    array(
        'title' => 'Link',
        'block' => 'a',
        'classes' => 'news-single-link',
        'wrapper' => true
    )
   );
   $init['style_formats'] = json_encode( $style_formats );
   return $init;
}
add_filter('tiny_mce_before_init', 'mce_mod');

如果您看一下，class-wp-editor.php会发现所使用的过滤器仍然存在，但是设置有所不同。

self::$first_init = array(
                    'theme' => 'modern',
                    'skin' => 'lightgray',
                    'language' => self::$mce_locale,
                    'formats' => "{
                        alignleft: [
                            {selector: 'p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li', styles: {textAlign:'left'}},
                            {selector: 'img,table,dl.wp-caption', classes: 'alignleft'}
                        ],
                        aligncenter: [
                            {selector: 'p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li', styles: {textAlign:'center'}},
                            {selector: 'img,table,dl.wp-caption', classes: 'aligncenter'}
                        ],
                        alignright: [
                            {selector: 'p,h1,h2,h3,h4,h5,h6,td,th,div,ul,ol,li', styles: {textAlign:'right'}},
                            {selector: 'img,table,dl.wp-caption', classes: 'alignright'}
                        ],
                        strikethrough: {inline: 'del'}
                    }",
                    'relative_urls' => false,
                    'remove_script_host' => false,
                    'convert_urls' => false,
                    'browser_spellcheck' => true,
                    'fix_list_elements' => true,
                    'entities' => '38,amp,60,lt,62,gt',
                    'entity_encoding' => 'raw',
                    'keep_styles' => false,
                    'paste_webkit_styles' => 'font-weight font-style color',

                    // Limit the preview styles in the menu/toolbar
                    'preview_styles' => 'font-family font-size font-weight font-style text-decoration text-transform',

                    'wpeditimage_disable_captions' => $no_captions,
                    'wpeditimage_html5_captions' => current_theme_supports( 'html5', 'caption' ),
                    'plugins' => implode( ',', $plugins ),
                );

我正在猜测，但我认为您需要更改要定位到的数组键formats。

编辑保留此位置，但OP确认此操作不执行他正在尝试的操作。

function mce_mod( $init ) {
        $init['formats'] = "{
                            alignleft: [
                                {selector: 'p,h3,h4,td,th,div,ul,ol,li', styles: {textAlign:'left'}},
                                {selector: 'img,table,dl.wp-caption', classes: 'alignleft'}
                            ],
                            aligncenter: [
                                {selector: 'p,h3,h4,td,th,div,ul,ol,li', styles: {textAlign:'center'}},
                                {selector: 'img,table,dl.wp-caption', classes: 'aligncenter'}
                            ],
                            alignright: [
                                {selector: 'p,h3,h4,td,th,div,ul,ol,li', styles: {textAlign:'right'}},
                                {selector: 'img,table,dl.wp-caption', classes: 'alignright'}
                            ],
                            strikethrough: {inline: 'del'}
                        }";
    return $init;
}
add_filter('tiny_mce_before_init', 'mce_mod');

请记住，这是完全未经测试的，因此您的行驶里程可能会有所不同。（并且在测试之前，请勿在生产站点上使用）。

继续向前

深入研究格式似乎是自定义的tinyMCE按钮。您可以看到该formatselect按钮已添加到mce_buttons_2中class-wp-editor.php。然后我跟踪到tinymce.js：

    editor.addButton('formatselect', function() {
        var items = [], blocks = createFormats(editor.settings.block_formats ||
            'Paragraph=p;' +
            'Address=address;' +
            'Pre=pre;' +
            'Heading 1=h1;' +
            'Heading 2=h2;' +
            'Heading 3=h3;' +
            'Heading 4=h4;' +
            'Heading 5=h5;' +
            'Heading 6=h6'
        );

考虑到这一点，我认为新目标将是1.（理想情况下）更改editor.settings.block_formats或2.通过过滤mce_buttons_2并添加自己的自定义版本来删除该按钮。

经过测试和工作

function mce_mod( $init ) {
    $init['block_formats'] = 'Paragraph=p;Heading 3=h3;Heading 4=h4';

    $style_formats = array (
        array( 'title' => 'Bold text', 'inline' => 'b' ),
        array( 'title' => 'Red text', 'inline' => 'span', 'styles' => array( 'color' => '#ff0000' ) ),
        array( 'title' => 'Red header', 'block' => 'h1', 'styles' => array( 'color' => '#ff0000' ) ),
        array( 'title' => 'Example 1', 'inline' => 'span', 'classes' => 'example1' ),
        array( 'title' => 'Example 2', 'inline' => 'span', 'classes' => 'example2' )
    );

    $init['style_formats'] = json_encode( $style_formats );

    $init['style_formats_merge'] = false;
    return $init;
}
add_filter('tiny_mce_before_init', 'mce_mod');

function mce_add_buttons( $buttons ){
    array_splice( $buttons, 1, 0, 'styleselect' );
    return $buttons;
}
add_filter( 'mce_buttons_2', 'mce_add_buttons' );

小警告：我不确定在哪里为下拉菜单项添加样式。在TinyMCE示例中，“红色标题”选项为红色。我不知道这个。如果您愿意，请告诉我。
