Maybe youÌtumọ̀ Yorùbá: ’ve had the same problem, and I hope this filter helps you solve it. The filter works by hooking the “syndicated_post” action of FeedWordPress and the“ save_post” action in the core of WordPress. For each potential post from a feed, the plugin attempts to find an identical SHA1 hash of the first 1024 non-whitespace characters (stripped of HTML tags) of the post content. If it finds a match the post is skipped. If not, the post is processed and a hash is inserted into the postÌtumọ̀ Yorùbá: ’s metadata. (Stored as key _dpf.) **NOTE:** No filter is going to be 100% accurate. This filter will stop _most_ or _some_ duplicates, but in all likelihood, will not stop _all_ of them. If you want a filter that stops _all_ duplicates, this isnÌtumọ̀ Yorùbá: ’t your solution. In my test installation I had 5 posted duplicates out of 125 syndicated posts (4% false negative) out of a corpus of about 300 duplicates. Most of those false negatives were due to slightly different HTML markup in the post content itself. So my approach isnÌtumọ̀ Yorùbá: ’t perfect, but it is “good enough” for me. ### Important Note This filter can only check future syndication posts. Whatever duplicates are already present in your WordPress installation youÌtumọ̀ Yorùbá: ’ll have to remove/clean- up on your own. ### License Copyright (C) 2012 by Mark R. Allen All rights reserved.

This works better than previous strategies. 1.3 Ìtumọ̀ Yorùbá: – Fixed a dumb typo. Rewrote the DB query using better wpdb methods( prepare and query). Changed from htmlescape2 to esc_html WP function. 1.2 Ìtumọ̀ Yorùbá: – Escaping the single quote (‘) character sometimes gives a conversion of ’ instead of ’ This caused a false negative and duplicate posts would be stored. Consider this release a temporary hack until I write a proper regex based title escape function. 1.1 Ìtumọ̀ Yorùbá: – Characters in post-titles like ‘&’ were not getting converted to HTML entities. This caused the post title comparison to register a false negative.( So duplicate posts would be added to your feed.) 1.0 Ìtumọ̀ Yorùbá: – initial release ## Àkójọpọ̀ Meta * Ẹ̀yà **1.5** * Ìgbàgbọ́hùn tó kẹ́yìn **ọdún 14 sẹ́yìn** * Àwọn ìgbéwọlẹ̀ tó ṣiṣẹ́ **200+** * Ẹ̀yà WordPress ** 2.8 tàbí ju bẹ́ẹ̀ lọ ** * Dánwò dé **3.3.2** * Èdè * [English (US)](https://wordpress.org/plugins/feedwordpress-duplicate-post-filter/) * Àwọn àmì * [duplicate posts](https://yor.wordpress.org/plugins/tags/duplicate-posts/)[feedwordpress](https://yor.wordpress.org/plugins/tags/feedwordpress/) * [Ìwòye Tó Péye](https://yor.wordpress.org/plugins/feedwordpress-duplicate-post-filter/advanced/) ## Àwọn ìbò Kò sí ìwádìí tí a tíì fi ránṣẹ́.
