本文實例講述了WordPress評論中禁止HTML代碼顯示的方法。分享給大家供大家參考。具體分析如下：
使用WordPress的朋友會發(fā)現(xiàn)如果我們開戶了博客評論會經(jīng)常看到大量的垃圾廣告,帶連接了,那么我們要如何禁止用戶輸入html標(biāo)簽原樣輸出,而不顯示呢,下面我來給大家介紹.
html標(biāo)題無非就是由“<”、“>”組成了,我們可以反它轉(zhuǎn)換成“<”、“>”，這樣通過HTML編譯,自動變成了“<”、“>” 我們也可以直接替換掉了
找到一國外人的代碼,搞定了,不過不一定他是原作者,在functions.php的PHP代碼里加入如下代碼:
復(fù)制代碼
代碼如下:
//禁用wordpress評論html代碼
// This will occur when the comment is posted
function plc_comment_post( $incoming_comment ) {
// convert everything in a comment to display literally
$incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']);
// the one exception is single quotes, which cannot be #039; because WordPress marks it as spam
$incoming_comment['comment_content'] = str_replace( "'", ''', $incoming_comment['comment_content'] );
return( $incoming_comment );
}
// This will occur before a comment is displayed
function plc_comment_display( $comment_to_display ) {
// Put the single quotes back in
$comment_to_display = str_replace( ''', "'", $comment_to_display );
return $comment_to_display;
}
add_filter( 'preprocess_comment', 'plc_comment_post', '', 1);
add_filter( 'comment_text', 'plc_comment_display', '', 1);
add_filter( 'comment_text_rss', 'plc_comment_display', '', 1);
add_filter( 'comment_excerpt', 'plc_comment_display', '', 1);
// This will occur when the comment is posted
function plc_comment_post( $incoming_comment ) {
// convert everything in a comment to display literally
$incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']);
// the one exception is single quotes, which cannot be #039; because WordPress marks it as spam
$incoming_comment['comment_content'] = str_replace( "'", ''', $incoming_comment['comment_content'] );
return( $incoming_comment );
}
// This will occur before a comment is displayed
function plc_comment_display( $comment_to_display ) {
// Put the single quotes back in
$comment_to_display = str_replace( ''', "'", $comment_to_display );
return $comment_to_display;
}
add_filter( 'preprocess_comment', 'plc_comment_post', '', 1);
add_filter( 'comment_text', 'plc_comment_display', '', 1);
add_filter( 'comment_text_rss', 'plc_comment_display', '', 1);
add_filter( 'comment_excerpt', 'plc_comment_display', '', 1);
