[Plugin: Category Page] Putting excerpts into pages (8 posts)

    Basically I wanted to have an excerpt of each post displayed in a page, so I wrote a little code and inserted it into the catlist.php and added a function to the functions.php of my theme (although you could put it into this file as well - but I use it elsewhere so it made sense there). So here goes:

    find the part where it starts talking about "// filter the content of a page " and then go down to where it says:

    foreach ($matches[1] as $key =>$v0) {
    	$catposts = get_posts('category='.$v0."&numberposts=".$limit);
    			foreach($catposts as $single):

    Now we're basically going to get rid of what it says in $output and replace it with a 150 character (non-word destructive) excerpt. So delete what it says there and replace it with this:

    $single_post_content = $single->post_content;
    $maxlength = 150;
    $excerpt = substr_replace($single_post_content, "", 0, $maxlength);
    $output .= "<li><a href='".get_permalink($single->ID)."'>".$single->post_title."</a></li><p>". $excerpt ."</p>";

    Now the beauty of this is if you want to have it be a 500 word excerpt all you do is change the value of $maxlength and that's that! Now after you update your file you need to go into your functions.php in your theme folder (or you can paste this at the top of your catlist.php file after the comments, whatever you wanna do - although I guarantee nothing if you choose the latter) and add the following code:

    function neat_trim($str, $n, $delim='...') {
    $str = str_replace("\n","",$str);
    $str = strip_tags($str);
      $len = strlen($str);
       if ($len > $n) {
           preg_match('/(.{' . $n . '}.*?)\b/', $str, $matches);
           return rtrim($matches[1]) . $delim;
       }
       else {
           return $str;
       }
    }

    I got that code from here so I take no credit for it, I just use it because it works. Now save your functions.php file and that's that!

    To note, it does strip out ANY formatting from the post, so if you have images, they will not show up. The reason I left it like this is because it counts the actual characters INCLUDING html markup, which makes it hard to determine what you're actually going to get when you do that.

    Hope this helps someone. I tried to contact the guys who made this, but their website is broken as hell and their forums are down as well.

    I apologize, I screwed up. The file you modify is page2cat.php not catlist.php (that was what I named my local file, der). Also, if you'd like to have it display the full contents of your post here's how:

    replace this:

    $excerpt = neat_trim($single_post_content, 500);

    with this:

    $excerpt = $single_post_content;

    and delete this:

    $excerpt .= "<a href='".get_permalink($single->ID)."'>more</a>";

    Now you've got a page that outputs everything on it with no hassles. :) Enjoy.

    Alright. So after a bit of tinkering, I've actually got it so you can now choose whether you want to include excerpts or full posts within the admin page for the plugin. You can choose one or the other but not both. Right now the default length for excerpts is 500 characters, but I'll add an option for that to be configurable later. So basically all you need to do is copy this script and paste it over your current page2cat.php file. To do that, just go to plugins -> editor. Next go to Select plugin to edit and choose Category Page and click select. It'll bring up your page2cat.php file in the editor. Click inside it and then hit ctrl+a (cmd+a) and then hit ctrl+v(cmd+v) and then click update file. It contains all the same functionality of the previous plugin, but adds in the option for excerpts and full posts.

    ?>

    So that's the modified code. I tried to contact the developer to submit it all to him, but there's no way to. Also, if it doesn't seem to work, deactivate it and then reactivate it. This is basically because the new database entries need to be put in and it may or may not do it when you update the file.

    Simple easy, peasy! Any questions just ask!!!

    Hi, just tried this out and it works.
    Though its not exactly what im looking for. As it is, it shows the full posts within the page. I would like to be able to show the full posts below the page as if it were the main page with the page as a sticky up top and below it were the categories I choose.

    Hope that makes sense :/

    hi there,
    This is great plugin, thanks!

    But I have problem with the plugin, I would like the final result just like this page http://dev.trismedia.com/three-lions/?page_id=74
    Two categories in one page, divided into 2 sections

    I tried the plugin with the following code in a page
    <h2>Latest News</h2>
    [catlist=1]

    <h2>Latest Events</h2>
    [catlist=3]

    But the result is http://dev.trismedia.com/three-lions/
    I got 1 category duplicated.

    Please help, thanks!
