Trucating tables in excerpt

  • I developed a theme and I wish to create a filters to properly truncate tables in excerpt. In fact, I have several posts containing long tables (several dozen rows), and I wish that, as an excerpt is requested, for example in a category page, only few rows are shown. How could I do that?

    Thank you in advance

    I’m not sure why t-p thinks you are trying to fix a commercial theme, they may have made the correct reply to the wrong post. Mistakes happen, don’t worry about it.

    Excerpts are truncated by wp_trim_excerpt(). Hook the filter of the same name and see if table tags appear in the excerpt. If so, the raw content was passed as a second parameter. Starting from where the function first truncated the output, search forward until a </tr> tag is encountered. It’s safe to truncate a table after this tag since it represents the end of a row. Append a </table> tag to close out the shortened table. Return the modified excerpt.

    To be 100% correct, there may be more table tags to close out like tbody, and other legitimate row ends, like </th> or <tfoot>. Browsers tend to be forgiving of malformed HTML, but if you want your output to validate, all possible scenarios need to be accounted for.

    ok, thank you. MY theme is not commercial at all, by the way. It’s a personal theme. ??
