Hey thanks, the plugin is amazing, just whats needed for WP.
@lzerner thanks for the code modification it displays the post almost exactly how i want,
how would i get my categories post to only display 5 or 6 lines of each post? Because some pages are extremely long showing the whole post!
isn't there some code i could insert to make each post like a preview and then have a readmore link somewhere.

Kind regards.

Hi, at first I thought including the option to display the content would be unnecessary. But since I´ve had so many requests, and lzerner was kind enough to write the code, I´ll add it to the next version of the plugin.

Thanks for using List Category Posts, and thanks a lot for the code!!
The plugin is getting better thanks to its users!

Regards

Hello, Ellen. I am not the author of this wonderful plugin, but a user like you. I have the same need you describe. I am also a programmer, so I wrote the enhancement myself and I'm sharing it here with you and the rest of the community of users of this plugin. I want to be clear that this version is not approved by the plugin author, Ferndando Briano, but I hope Fernando will include my changes in his next version.

In my enhancement of the plugin, you will see you can use the "content" attribute to instruct that the plugin should display the full content of the posts, like this:

[catlist name=mycategory content=yes]

If you specify both excerpt=yes and the content=yes attributes, then the content will be shown, even for posts that have an excerpt. For posts that happen to have an excerpt only, with no content, in this case specifying both excerpt=yes and the content=yes will display the excerpt rather than displaying empty content.

This version of the plugin also has a fix to a bug that prevented the "name" attribute from working correctly.

Since I don't see a way to attach a file to this post, I'll show the whole code for the enhanced list_cat_posts.php file and templates/default.php template. You can copy and paste these into a text editor to make new files to replace the ones in your WordPress plugins/list_cat_posts folder (or just wait for Fernando to incorporate these changes into the next version):

list_cat_posts.php

Code:

<?php

/*

Re: List Category Posts WordPress Plugin support

There is a simple but serious bug in the handling for the name attribute. See lines 48-52:

Code:

     48         if($atts['name']!='default' && $atts['id']!='0'){

     49                 $category = 'category_name=' . $atts['name'];

     50         }else{

     51                 $category = 'cat=' . $atts['id'];

     52         }

This says, if the "name" attribute has been explicitly set and the "id" attribute has also been set, then use the category_name, otherwise, use the category ID. That's contrary to the documentation, which says:

Quote:

If you use both arguments (wrong!), List Category Posts will show the posts from the category in 'name'.

In the above implementation, if you set both arguments, List Category Posts shows the posts from the category in "id" instead.

It's very bad, though, if you provide only the "name" argument. In this case, since $atts['id'] is still '0', you skip line 49 and instead execute line 51:

Code:

$category = 'cat=' . $atts['id'];

The result is that you see all posts listed from all a categories.

In other words, the "name" argument doesn't ever work. The only way to restrict the category in your current implementation is to use the "id" argument.

The fix to this is very simple. In line 48, change

Code:

$atts['id']!='0'

Code:

$atts['id']=='0'

(change from "not equal" to "equal"), so the whole line is:

Code:

48 if($atts['name']!='default' && $atts['id']=='0'){

In this case it will behave as you documented it.

In a subsequent post, I will provide an enhancement to your code that allows the inclusion of post content on the page as an alternative to the post excerpt.

Thank you for a wonderful little plugin that has perfectly solved my requirement to put category listings into the page navigation.

Qtranslate Multilingual Support for List Category Posts Plug

alfirin — Thu, 12 Nov 2009 07:19:46 -0600

Hi!

For everyone using Qtranslate in their websites, here is a way to make List Category Posts Plugin with multilingual support to show the correct part of the post title in each language version.

In list_cat_posts.php add this line

Code:

$catposts = __($catposts);

at the end of

Code:

 //Build the query for get_posts()

   $catposts = get_posts($category.'&numberposts=' . $atts['numberposts'] .

            '&orderby=' . $atts['orderby'] .

            '&order=' . $atts['order']);

   $catposts = __($catposts);

It works perfect for me. Thanks for this great plugin!

Cheers,

List Category Plugin

ellenstevens — Wed, 11 Nov 2009 18:10:09 -0600

Thank you so much for creating this plugin! I think it has been a much needed feature on wordpress for some time.

Is it possible to display the entire posts, versus just a title list? I understand the excerpts can be posted, but I would like to see all of the post. Is that possible?

thanks,

ellen

Hey yo Glassy and Nando...

Here is the fix for the offset that Glassy is asking about...

Glassy, what you really mean is that the posts that are listed are those which are already been showed, so in order to avoid that I reprogrammed the plugin to use the offset function of the :

Offset Parameter

You can displace or pass over one or more initial posts which would normally be collected by your query through the use of the offset parameter.

The following will display the 5 posts which follow the most recent (1):

Code:

query_posts('posts_per_page=5&offset=1');

as stated in the wp CODEX site:

http://codex.wordpress.org/Template_Tags/query_posts#Parameters
Scroll all the way down to offset..

So the fix is to add a new parameter:

Code:

'offset' => '4',

and to send that parameter to the query_post():

Code:

'&offset=' . $atts['offset'] );

and to add that parameter to the code:

Code:

[catlist ID=1 numberposts=5 excerpt=yes date=yes offset=4]

This will list all the post starting at the 4th post on the cat id 1, all you need to do is.. can you count?

The final fix to the plugin shows as follows:

Code:

function catlist_func($atts, $content=null) {

   $atts=shortcode_atts(array(

         'id' => '0',

         'name' => 'default',

         'orderby' => 'date',

         'order' => 'desc',

         'offset' => '4', //Permite especificar un offset para comensar a listar los posts, contribucion por Levi Vasquez

         'numberposts' => '5',

         'date' => 'no',

         'author' => 'no',

         'dateformat' => get_option('date_format'), //By Verex

         'template' => 'default',

         'excerpt' => 'no',

         'exclude' => '0'

      ), $atts);

   return list_category_posts($atts);

}

add_shortcode('catlist', 'catlist_func');

function list_category_posts($atts){

   if($atts['name']!='default' && $atts['id']!='0'){

      $category = 'category_name=' . $atts['name'];

   }else{

      $category = 'cat=' . $atts['id'];

   }

   //Build the query for get_posts()

   $catposts = get_posts($category.'&numberposts=' . $atts['numberposts'] .

            '&orderby=' . $atts['orderby'] .

            '&order=' . $atts['order'] .

            '&offset=' . $atts['offset'] ); //Permite especificar un offset para comensar a listar los posts, contribucion por Levi Vasquez

Cheers mates!!!!

Levi.

Hi,

I had been looking for an answer to a question I had and the answer WAS in the comments but since they were removed, I can't find the answer now.

The problem I am having is that when the plugin generates the list, it also puts the pages that the list is on IN the list. Can this be disabled or removed?
