add_editor_style()文章编辑器添加一个自定义的CSS样式表

目录

描述

Allows theme developers to link a custom stylesheet file to the TinyMCE visual editor. The function tests for the existence of the relative path(s) given as the $stylesheet argument against the current theme directory and links the file(s) on success. If no $stylesheet argument is specified, the function will test for the existence of the default editor stylesheet file, editor-style.css, against the current theme directory, and link that file on success.

If a child theme is used, both the current child and parent theme directories are tested and both the files with the same relative path are linked with this single call if they are found.

To link a stylesheet file from a location other than the current theme directory, such as under your plugin directory, use a filter attached to the mce_css hook instead.

Note that the behavior of this function with respect to child themes was changed in Version 3.4 and changed back in Version 3.5, see the Notes section below.

用法

add_editor_style() 用法

参数

$stylesheet

(string/array) (可选) Path to a stylesheet file, relative to the current theme directory, or an array thereof to link multiple stylesheet files.

默认值: "editor-style.css"

If a child theme is used, both the current child and parent theme directories are considered (see Description).

As of version 3.6, http or https URLs (e.g., http://example/style.css) can be used. Root-relative URLs will not work: e.g., /editor-style.css is treated the same as editor-style.css.

Paths with a query string (e.g., editor-style?ver=…) will fail to be added. You can work around that by using the equivalent http(s) URL, e.g. , http://example/editor-style.css?ver=…. (get_stylesheet_directory_uri() and home_url() can help you build "full" URLs.)

Call get_editor_stylesheets() to see which styles have been added.

示例

Basic Usage

Add the following to the functions.php file of your theme.

Next, create a file named custom-editor-style.css in your themes root directory. Any CSS rules added to that file will be reflected within the TinyMCE visual editor. The contents of the file might look like this:

Using Google Fonts

Google Fonts API provides a single URL for a CSS file that can include multiple variants of a type face, separated by commas. Commas in a URL need to be encoded before the string can be passed to add_editor_style.

Reusing Your Theme Styles

You can reuse the styles from your theme stylesheet file in your custom editor stylesheet file using the @import CSS rule. Working on the previous example, put the following instead into the custom-editor-style.css file.

If necessary, change 'style.css' to the path to your theme stylesheet, relative to the custom-editor-style.css file.

Choosing Styles Based on Post Type

To link a custom editor stylesheet file based on the post type being edited, you can use the following in the functions.php file of your theme. This assumes the stylesheet files with names in the form of editor-style-{post_type}.css are present directly under your theme directory.

Note that the pre_get_posts action hook is used to ensure that the post type is already determined but, at the same time, that TinyMCE has not been configured yet. That hook is not run when creating new posts, that is why we need to use it in combination with the init hook to achieve a consistent result.

add_editor_style() 示例

注意

  • As of Version 3.4, WordPress will link the stylesheet file only if its path determined by the $stylesheet argument passes the file_exists() test, so arguments like "editor.css?version=1.0" will not work. Prior to Version 3.4, this will apply only to child themes.
  • In Version 3.4, using this function by a child theme to add a stylesheet file will not link the file if a stylesheet file on the same relative path was already added by a parent theme. As of Version 3.5, this was fixed and WordPress will look for the file in both the parent and child theme directories, as was the case before Version 3.4. See the ticket #21026 for details about these changes.
