经常受到垃圾评论的滋扰,下面的代码可能对你有所帮助。

将以下代码粘贴到你的主题functions.php模板中。

任何包含在$ bad_comment_content数组内的字符,将会被自动拒绝留言。
 

function in_comment_post_like($string, $array) {

foreach($array as $ref) { if(strstr($string, $ref)) { return true; } }

return false;

}

function drop_bad_comments() {

if (!empty($_POST['comment'])) {

$post_comment_content = $_POST['comment'];

$lower_case_comment = strtolower($_POST['comment']);

$bad_comment_content = array(

'viagra',

'hydrocodone',

'hair loss',

'xanax',

'tramadol',

'russian girls',

'russian brides',

'lorazepam',

'adderall',

'dexadrine',

'no prescription',

'oxycontin',

'without a prescription',

'sex pics',

'family incest',

'online casinos',

'online dating',

'cialis',

'best forex',

'amoxicillin'

);

if (in_comment_post_like($lower_case_comment, $bad_comment_content)) {

$comment_box_text = wordwrap(trim($post_comment_content), 80, "\n ", true);

$txtdrop = fopen('/var/log/httpd/wp_post-logger/nullamatix.com-text-area_dropped.txt', 'a');

fwrite($txtdrop, " --------------\n [COMMENT] = " . $post_comment_content . "\n --------------\n");

fwrite($txtdrop, " [SOURCE_IP] = " . $_SERVER['REMOTE_ADDR'] . " @ " . date("F j, Y, g:i a") . "\n");

fwrite($txtdrop, " [USERAGENT] = " . $_SERVER['HTTP_USER_AGENT'] . "\n");

fwrite($txtdrop, " [REFERER ] = " . $_SERVER['HTTP_REFERER'] . "\n");

fwrite($txtdrop, " [FILE_NAME] = " . $_SERVER['SCRIPT_NAME'] . " - [REQ_URI] = " . $_SERVER['REQUEST_URI'] . "\n");

fwrite($txtdrop, '--------------**********------------------'."\n");

header("HTTP/1.1 406 Not Acceptable");

header("Status: 406 Not Acceptable");

header("Connection: Close");

wp_die( __('bang bang.') );

}

}

}

add_action('init', 'drop_bad_comments');
