Allow More HTML Tags in WordPress Comments

文字压力允许在员额评论内容中选择几个超文本标。 这当然是一个非常麻烦的特点,因为它防止了XSS的安全漏洞和其他恶意守则被mmer、黑客和女佣注射。 不幸的是,还有其他许多方面,博客可能希望得到支持;例如,技术博客可能希望支持<条码>。 很奇怪的是,在你的言辞中允许更多的主角:

// Create function which allows more tags within comments
function allow_pres() {
	global $allowedtags;
	$allowedtags[ pre ] = array( class =>array());
}

// Add WordPress hook to use the function
add_action( comment_post ,  allow_pres );

The global $allowedtags variable holds an array of allowed comment tags, so adding the pre key will allow PRE elements within comments.  The class key within the pre array allows the class attribute for any PRE tags posted within the comment, so not only can you allow additional HTML tags, but you can also specify allowed attributes too!  This function is added to the comment_post hook (same hook that AJAX comments use) so as to only add desired tags when a comment is posted.
