wp_kses_hook()
云策文档标注
概述
wp_kses_hook() 函数用于在 KSES 过滤内容前应用 'pre_kses' 钩子,允许开发者自定义内容过滤逻辑。它接收内容、允许的 HTML 和协议参数,并返回过滤后的字符串。
关键要点
- 函数调用 apply_filters('pre_kses', ...) 来触发 'pre_kses' 钩子,这是 WordPress 中唯一的 KSES 钩子。
- 参数包括 $content(要过滤的内容)、$allowed_html(允许的 HTML 元素和属性数组或上下文名称)和 $allowed_protocols(允许的 URL 协议数组)。
- 返回值为通过 'pre_kses' 钩子过滤后的字符串内容。
代码示例
function wp_kses_hook( $content, $allowed_html, $allowed_protocols ) {
/**
* Filters content to be run through KSES.
*
* @since 2.3.0
*
* @param string $content Content to filter through KSES.
* @param array[]|string $allowed_html An array of allowed HTML elements and attributes,
* or a context name such as 'post'. See wp_kses_allowed_html()
* for the list of accepted context names.
* @param string[] $allowed_protocols Array of allowed URL protocols.
*/
return apply_filters( 'pre_kses', $content, $allowed_html, $allowed_protocols );
}
