[Plugin: WordPress SEO by Yoast] %%Excerpt%% for Chinese Character

  • Hello.
    The plugin cannot auto generate %%Excerpt%% for Chinese Character. This is because it use substr which don’t support UTF-8.

    This can be fixed by changing /wordpress-seo/inc/wpseo-functions.php:

    Search:
    '%%excerpt%%' => ( !empty($r->post_excerpt) ) ? strip_tags( $r->post_excerpt ) : substr( strip_shortcodes( strip_tags( $r->post_content ) ), 0, 155 ),

    Replace with:
    '%%excerpt%%' => ( !empty($r->post_excerpt) ) ? strip_tags( $r->post_excerpt ) : mb_substr( strip_shortcodes( strip_tags( $r->post_content ) ), 0, 155,'utf-8' ),

    Each time I upgrade the plugin, I have to do it manually. Would you fix it? Thanks.

    Regards,
    David Pi

    Hello. Did anyone read this?

    It’s not why you posted, but it helped me in a problem I was having trouble solving. So yes, I read it.

    hey David, why don’t you tweet @yoast and let him know directly? ?? And don’t forget to mark this thread as resolved.

    Unfortunately mb_substr is not a default function in PHP, so I cannot rely on it. Let me figure out another solution.

    Does this fix it:

    '%%excerpt%%' => ( !empty( $r->post_excerpt ) ) ? strip_tags( $r->post_excerpt ) : utf8_encode( substr( strip_shortcodes( strip_tags( utf8_decode( $r->post_content ) ) ), 0, 155 ) ),

    ?

    Hello. I’ve tried the code but it doesn’t fix it. All the Chinese Characters became “?”.

    Hmm shit. Ok, looking at other options.

    I’ve seen other plugins test for the existence of the mb_ version of a function and if present use that, otherwise use the normal one. This way it becomes a matter of adding to the plugin description something to the effect that for full CJK support mbstring is required, and maybe to the admin panel a warning informing a user with WPLANG == jp_JP etc. and no mbstring that he needs to contact his host for them to install this extension or support will be limited.

    Yeah I’ll probably have to fall back to something like that indeed.

    Unfortunately mb_substr is not a default function in PHP, so I cannot rely on it. Let me figure out another solution.

    Is this some kind of joke?

    WordPress widely uses mb_* functions and already has implementation for PHP functions that either missing from older PHP versions or not included by default in \wp-includes\compat.php

    So, please use the code above.

    Or, alternatively, you can use wp_html_excerpt:
    '%%excerpt%%' => (!empty($r->post_excerpt)) ? strip_tags($r->post_excerpt) : wp_html_excerpt(strip_shortcodes($r->post_content),155),
    It would be more correct, because essentially removes part of an entity at the end of string.

    In croatian language with wp_html_excerpt problem is resolved ?? … thanks

    Thank you. Had the same problem with Russian characters. Your post helped ??

    Thanx waitd!

    Always the same probleme with 1.2.8.3 the € isn’t displayed. Hope the next relase will fix that.
