Change to Recent Articles Snippet

[Maddog452]

I am currently using the following SSI code in a PHP Box on my front page.

Code Select Expand

ssi_boardNews($board = 17.0 , $limit = 5, $start = null, $length = 300, $output_method = 'echo');

Unfortunately, this means that the board that this function points to needs to be open to guests.

Is it possible to have the block on the front page that offers an article from one board if a guest and then another board if they are members??  I was thinking something like:

Code Select Expand


if ($context['user']['is_guest'])
   ssi_boardNews($board = 17.0 , $limit = 5, $start = null, $length = 300, $output_method = 'echo')
else
    ssi_boardNews($board = 6.0 , $limit = 5, $start = null, $length = 300, $output_method = 'echo')


I know the above code wouldnt work (I'm dumb but not that dumb) plus the above function still would not work because the SSI function requires the target board to be accessable to guests

That general form would work, though it would have to be cleaned up some.

But is there a reason you even SHOW the block to guests. The point becomes moot, if you simply uncheck the box that enables Guests to see this block, doesn't it?

But if you want guests to see an alternate board, then:

Code Select Expand

global $$context;
if ($context['user']['is_guest']) {
   ssi_boardNews(17, 5, null, 300); }
else {
   ssi_boardNews(6, 5, null, 300); }

Should work fine IF guests are to be shown entries from board 17 and members are to be shown entries from board 6.

Thanks for the code.

The issue from my side is that to use the "ssi_boardNews" function, the board needs to be accessible to guests.

Unfortunately a newspaper reporter quoted one of the Obituaries in our news section and then went on to "Quote inside sources", which make me look like I provided the datail from our members only forum.

How can I stop that?

Let's make sure we're using the same terms here. A board is a section within the forum and you can make them (and the topics/posts within) inaccesible to guests. Were a guest to view a block which displayed the ssi_boardNews output, it would NOT include anything from boards which don't grant access to guests because of this bit of code in the function:

Code Select Expand

// Make sure guests can see this board.
$request = db_query("
SELECT ID_BOARD
FROM {$db_prefix}boards
WHERE " . ($board === null ? '' : "ID_BOARD = $board
AND ") . "FIND_IN_SET(-1, memberGroups)
LIMIT 1", __FILE__, __LINE__);
if (mysql_num_rows($request) == 0)
{
if ($output_method == 'echo')
die($txt['smf_news_error2']);
else
return array();
}

That's why you would supply a board # for guests which points to a publicly viewable board and different 'restricted to logged in members' board for those logged in.

So, you can give highly constrained access (to, say, one single board) to guests (and let them only READ that one at that). And guests will NOT be able to see anything more of your forum than that. They will certainly not be shown (by ssi functions) posts from boards to which they have no access.

Thanks for taking the time to help me understand this.

Firstly my set up so far.  All boards are excessible by members and only one (#17) is accessible to guests (I will probably change that to just an article) once I work out how to do it.

I tried the first section of code:

Code Select Expand

global $$context;
if ($context['user']['is_guest']) {
   ssi_boardNews(17, 5, null, 300); }
else {
   ssi_boardNews(6, 5, null, 300); }

It works perfectly except when I actually log in and I get the following error message:

You cannot specify a board that doesn't allow guests. Please check the board ID before trying again

Board #6 is my members news board and is set with all membergroups getting access but the Guest check box is unchecked - hence the error. Is there a way to modify the function or do I need to find the full function and post that into the function after the "else".

When people log in as guests they get the members only speil.

The second block of code - is that from the source code or should I insert that in the block with (or instead of) the first lot of code??

I can give you a login to have a look if you want.  PM me.

Sorry. Was simply not familiar with that aspect of the ssi_boardNews function.

That bit of code was just to illustrate some of the constraints the code puts on guests. In fact, that bit of code is actually the culprit in this case.

I would tend to say you should copy the necessary code into your block rather than modify the function. Otherwise, the next time you upgrade, the SSI.php will simply be overwritten and you'll encounter this problem again until you go and modify it again.

Without taking the time to pull apart the function to get rid of things you don't need but it has to allow for, simply copy the whole thing and comment out the name and the enclosing brackets. Directly assign the values that would have been passed in (or defaulted to). Then comment out the chunk that's causing the problem (and it's actually noted as the place where the code is to "// Make sure guests can see this board.").

You end up with this:

Code Select Expand


$board = 6;
$limit = 5;
$start = null;
$length = 300;
$output_method = 'echo';

// Show the latest news, with a template... by board.
// function ssi_boardNews($board = null, $limit = null, $start = null, $length = null, $output_method = 'echo')
// {
global $scripturl, $db_prefix, $txt, $settings, $modSettings, $context;
global $func;

loadLanguage('Stats');

// Must be integers....
if ($limit === null)
$limit = isset($_GET['limit']) ? (int) $_GET['limit'] : 5;
else
$limit = (int) $limit;

if ($start === null)
$start = isset($_GET['start']) ? (int) $_GET['start'] : 0;
else
$start = (int) $start;

if ($board !== null)
$board = (int) $board;
elseif (isset($_GET['board']))
$board = (int) $_GET['board'];

if ($length === null)
$length = isset($_GET['length']) ? (int) $_GET['length'] : 0;
else
$length = (int) $length;

$limit = max(0, $limit);
$start = max(0, $start);

// // Make sure guests can see this board.
// $request = db_query("
// SELECT ID_BOARD
// FROM {$db_prefix}boards
// WHERE " . ($board === null ? '' : "ID_BOARD = $board
// AND ") . "FIND_IN_SET(-1, memberGroups)
// LIMIT 1", __FILE__, __LINE__);
// if (mysql_num_rows($request) == 0)
// {
// if ($output_method == 'echo')
// die($txt['smf_news_error2']);
// else
// return array();
// }

// mysql_free_result($request);

Just paste that mass in where the "ssi_boardNews(6, 5, null, 300);" is (be careful to retain the closing curly bracket which follows on that line).

Thanks for that.  That funxtion rocks.

The SSI function only shows the original post - the actual news.  How do I modify this one to show only the news??

Sorry about the constant stream of dumb questions.  I am struggling to follow the code.  The simple "If" statements are ok but after that, I get very confused.

Disragard my last.  I does work.  My members did something I didn't notice.

Thanks

[jacortina]

Good, because the way the code works, I'd be hard pressed to figure out how it was looking at anything but the first post in a topic.

Sorry to pester after more than a month but is it possible to modify the second part of this to show more than one board (eg the 5 or 6 most recent posts from two or three boards).

Maybe inserting an Array??

I dunno.
