hey guys,

i'm fairly new to simpleportal and have a question about article categories .. i've been looking through simpleportal and can find an answer

what i want on my homepage is a block that allows you to click to view a list of articles under a category name. so for example when i click on a link to see game news the link takes me to the 'games news' category, listing all articles in that category.

my issue isn't about settings this block up .. it's about how i link to the category id, and how to display the articles for that category id on a separate page.

thanks in advance for any help

My suggestion, would be that you make a Custom PHP Page, which you can add code to show the articles for a particular category

Ie. index.php?pageid=showarticles;cat=x

Then use $_REQUEST['cat'] to get the id, and show the articles. Refer to the 'sportal_articles' and 'sportal_articles_callback' functions from the Sources/PortalArticles.php file, for help on accessing and displaying articles. The Themes/default/PortalArticles.template.php file may also be useful.

cheers nathaniel .. i'll look into it 

[mack]

wow ..

well since i wrote i've been trying a few different things to get it working, and failing .. hard (hehe)

i took your advice and tried to work with the sportal_articles and sportal_articles_callback functions in the file you mentioned, but it's led to all sorts of problems (which i've only just reset)

my php is very rusty .. can anyone be more definitive about the code i need in my custom php block?

thanks again for any help

As this is really a Customization request and we have just had a release, its a bit unreasonable to expect someone to code it for you within a day or two.

Anyway try this code in a custom page.

thanks for the reply .. sry if i came across as being unreasonable .. i just thought this would've come up before somewhere which is why i was a little surprised at the lack of response .. but np

thanks for the code tho, i'll give it a whirl

[Nathaniel]

Any luck with that code mack?

[mack]

Any luck with that code mack?

sorry for the delayed response

in short .. no. basically it showed all of the articles, from all categories. i might've misunderstood something in your post ofc.

[Nathaniel]

Doesn't it display a list of categories at the top of the page? If you select a specific category, then it will only show articles from that category.

[mack]

i'll set it up again later on and see .. can't say i noticed that the first time i tested it

[mack]

i think i hadn't noticed it first time around because of the way my design restricts a certain amount of simpleportal's previews

but yes .. it works really well ..

for anyone interested in how i incoporated it:

all i needed to do was create a page in simpleportal with the php in it (making sure the page type was selected as 'php'). then i added some buttons from my home page to point to each category that the new page switches between ('cat=1', 'cat=2' etc) and that was that.

@nathaniel - hopefully by the time you read this i'll have added in the extra buttons so you can see it at work (clan4 web site .. links on the right to games news, hardware news, and odds 'n' ends). oh and nathaniel .. awesome mate .. thank you very much

I keep getting this error when I try to implement this:

Fatal error: Call to undefined function: db_query() in /home/xxxx/public_html/mysite/Sources/Subs-Portal.php(1333) : eval()'d code on line 12

Argh!

[Nathaniel]

@peteewheat,
That code is for SMF 1.1.x, you are running SMF 2, so the code won't work properly.

I can convert the code for SMF 2 (when I find the time) if you want?

[peteewheat]

Yes! That would be awesome. I have a football league with news articles broken out by team (30'ish teams). Each team has their own page and I would love to break out the articles for each team.

[Nathaniel]

The code below is the same as the code above, but adapted for SMF 2.
