exclude article

lindabb · 2023-02-17 17:28:38

Hello,
How I exclude article with id in :

<txp:article class=“article-list” form=“article_listing” limit=“10” wraptag=“ul” />

this is from the demo that comes with textpattern installation.
also, I like to add like first 100 characters from the article body below the title, with read more.

Thank you

Hello, welcome to the forum.

To exclude some articles, pass their ids to exclude attribute:

<txp:article exclude="1,2,3" class="article-list" form="article_listing" limit="10" wraptag="ul" />

To truncate the article body, avoiding cutting inside a word, if possible:

<txp:body  trim="/(?<=^.{95})(\w{0,5})[\s\w].+$/" replace='$1... <txp:permlink>Read more</txp:permlink>' />

Hope it helps.

Thank you so much, worked perfectly after fixed replaced ” with “

lindabb · 2023-02-17 22:33:26

the exclude worked, but the body for some reason not showing

<txp:article exclude="1,6" class="article-list" form="article_listing" limit="10" wraptag="ul" >  
                       <txp:body trim="/(?<=^.{95})(\w{0,5})[\s\w].+$/" replace='$1... <txp:permlink>Read more</txp:permlink>' />   
                       </txp:article>

Thank you

You should probably remove form attribute?

Edit: Also remove eventual HTML tags first to avoid broken markup:

<txp:body escape="tags" ... />

… And maybe the link <txp:permlink>Read more</txp:permlink> have to be placed outside the <txp:body /> tag (otherwise, the link tag is escaped).

Hello,

Thank you all for your suggestions, none of above worked, as I said the exclude part worked,
but list of articles title (or header) with first 100-150 characters with read me didn’t work, will be nice if some post real working example.
needed example: list of all articles (titles) with ability to exclude articles by ids, with h1 and then show part of the body first 100-150 characters with read more link.

Thank you for any help I get

I had no luck with regex variant either in txp 4.8.8, though the regex does work very nicely (see here).

@lindabb, See this post (and the thread above it) for another way that does currently work, though it’s not quite as neat because it can stop mid-word:

<txp:evaluate query='substring("<txp:body escape="tags" />", 1, 150)' escape="trim" /><txp:evaluate query='string-length("<txp:body escape="tags" />" > 150)'>…</txp:evaluate>
<txp:permlink>Read more</txp:permlink>

Sorry, we need a s modifier here, to match multiline bodies:

<txp:hide process="1" trim="/^\s*(.{95}\w*)\b.+$/s" replace='$1... <txp:permlink>Read more</txp:permlink>'>
    <txp:body escape="tags" />
</txp:hide>

And thanks to Pat64 for the escape fix.

Thank you all for all suggestions,
But Jakob’s solution worked very well, million stars!
BTW: this is the best active forum for open source CMS.
I’m just 2 weeks with textpattern I learned a lot.

Here is final working title with working first 150 characters with read more:

<txp:article exclude="1" class="article-list"  limit="20" wraptag="ul" > 

    <h3><txp:title /></h3>

    <txp:evaluate query='substring("<txp:body escape="tags" />", 1, 150)' escape="trim" /><txp:evaluate    query='string-length("<txp:body escape="tags" />" > 150)'>…</txp:evaluate>
<txp:permlink>Read more</txp:permlink> <br>


          </txp:article>

Thank you all for your time and support.

Note: the solution provided by etc is much better because the Regex in use doesn’t strip letters into the final word. A kind of good programming lesson as always.

lindabb · 2023-02-20 20:38:10

Thank you Pat64,
but I couldn’t use etc’s code . I got error
strip_tags(): Passing null to parameter #1 ($string) of type string is deprecated while parsing form None on page xx
