Blog wordpress mo\u017ce otrzymywa\u0107 ponad 100 komentarzy spamowych (produkowanych przez roboty spamuj\u0105ce) dziennie, co jest denerwuj\u0105ce.<\/p>\n

\"Najskuteczniejsze<\/a><\/p>\n

Generalnie mog\u0105 one zosta\u0107 przechwycone przez wtyczki, takie jak Akismet, jednak dane te s\u0105 nadal przechowywane w bazie danych, zanim zostan\u0105 r\u0119cznie usuni\u0119te lub po<\/a> up\u0142ywie daty wa\u017cno\u015bci<\/a>.<\/p>\n

LEONA<\/a> zapewnia sprytne rozwi\u0105zanie zapobiegaj\u0105ce przedostawaniu si\u0119 tych spamowych komentarzy nawet do bazy danych. Polega na umieszczeniu w formularzu ukrytego pola i ustawieniu warto\u015bci, gdy u\u017cytkownik naci\u015bnie klawisz (onkeyup). Wi\u0119c je\u015bli warto\u015bci nie pasuj\u0105, my\u015blimy, \u017ce nie jest to sk\u0142adane przez cz\u0142owieka.<\/p>\n

wordpress zapewnia filtr preprocess_comment<\/strong>, dzi\u0119ki czemu mo\u017cesz sprawdzi\u0107 komentarze i wyj\u015b\u0107 ze strony wcze\u015bniej za pomoc\u0105 wp_die()<\/strong>.<\/p>\n

WP Official API m\u00f3wi (https:\/\/codex.wordpress.org\/Plugin_API\/Filter_Reference\/preprocess_comment<\/a> ), $commentdata zawiera nast\u0119puj\u0105ce informacje:<\/p>\n

Nast\u0119pnie mo\u017cemy u\u017cy\u0107 tej wtyczki, aby umo\u017cliwi\u0107 pingback\/trackback (co moim zdaniem jest przydatne) i skutecznie pozby\u0107 si\u0119 komentarzy spamowych.<\/p>\n
