MergeBlock() with array of arrays (with inner numeric indexes)

This (single array with inner numeric indexes) works
My data array (slurped and converted into array from an RSS feed)

Using the following php (works)

global $xmlobj;
include ("./xml_parser_KD.php");

$url = "http://rss.azstarnet.com/index.php?section=s1a";
$xml = implode('', file($url));
$xmlobj = XML_unserialize(&$xml);

// blk1 gets me the top level info about the RSS feed...
$TBS->MergeBlock('blk1', 'array', array($xmlobj));
// blk2 drills down into the array to get the multiple items...
$TBS->MergeBlock('blk2', 'array', $xmlobj[rss][channel][item]);

$TBS->Show();

and the .html template for this (works)

<tr><th align=left colspan=2>       
RSS Feed for    "<a href="[blk1.rss.channel.link;block=tr;.]" target="_blank">[blk1.rss.channel.title;.]</a>"
</th></tr>

<tr bgcolor="#ffffcc">
<td valign=top><font size="-0" color="Blue">[blk2.title;block=tr;.]</font></td>
<td valign=top> <font face="Arial" size="-1" color="navy">[blk2.description;.]</font></td>
</tr>

Now the problrem... the "multiple" RSS feeds I generate an array of arrays (another array for each of multiple RSS feeds)
the php to generate the data array

Yes, I think main/sub blocks are the possible approach, and here is what I am trying for the PHP...

include ("./xml_parser_KD.php");
$list[] = "http://cruisingsailor.org/component/option,com_rss/feed,RSS2.0/no_html,1";
$list[] = "http://rss.azstarnet.com/index.php?section=s1a";

foreach ($list as $key=>$url){
$xml = implode('', file($url));
$xmlobj[] = XML_unserialize(&$xml);
unset($xml);
}

$TBS->MergeBlock('main', 'array', $xmlobj );
$TBS->MergeBlock('sub', 'array', 'xmlobj[%p1%][channel][item]' );

$TBS->Show();

The above php code gives array of arrays like this (example of just two feeds)

But now I'm stumped -- I can't see how to do recursion through each of the top level arrays and then also access the numeric indexes of "items" inside of each RSS array.

My template like this...

<tr><th align=left colspan=2>       
RSS Feed for    "<a href="[main.rss.channel.link;block=tr;.]" target="_blank">[main.rss.channel.title;.]</a>"
</th></tr>

<tr bgcolor="#ffffcc">
<td valign=top><font size="-0" color="Blue">[sub.title;block=tr;p1=[main.$];.]</font></td>
<td valign=top> <font face="Arial" size="-1" color="navy">[sub.description;.]</font></td>
</tr>

And I tried that and many other templates for a long time :( but could not get anything running.

Any examples or ideas would be very appreciated!

Thanks for TBS

Re: MergeBlock() with array of arrays (with inner numeric indexes)

Hi TomH,
I'm not sure if this helps any, and I have not time to test it. Besides, I'm not quite sure I understand your question well enough. But does this message on this same forum help?

sub-block indexing error? Re: MergeBlock() with array of arrays (with inner numeric indexes)

Hi Pirjo,
Yes, that is the exact model I am using now!

$TBS->MergeBlock('main', 'array', $xmlobj );
$TBS->MergeBlock('sub', 'array', 'xmlobj[%p1%][rss][channel][item]' );

and

<tr bgcolor="#ffffcc">
<td valign=top><font size="-0" color="Blue">
<a href="[sub.link;p1=[main.$];block=tr;.]" target="_blank">[sub.title;p1=[main.$];.]</a></font></td>

<td valign=top> <font face="Arial" size="-1" color="navy">[sub.description;p1=[main.$];.]</font></td>
</tr>

You can see my actual testing with results page, php source, and template source by looking here http://tomhenry.us/tbs3/rss_object_read/

There are two errors showing on the results page "multi"
Note the following errors in the results...
* the sub-block items are rendered _below_ the three RSS feed parents when they should be just below the second RSS feed
# that the four 'items' that are displayed are the child 'items' that associate with the second RSS feed parent

Maybe from there and the source that is available there you might seee what I'm missing.

Re: sub-block indexing error? Re: MergeBlock() with array of arrays (with inner numeric indexes)

Sorry, I can't help you test this, too busy, too sleepy, 4:25 a.m...
But here's a very old 3-level TBS example I found, originally by Skrol29, I believe:

<table border="1" cellspacing="0" bordercolor="#0000FF">

<tr>

    <td>[b1.$;block=tr]</td>

    <td>

      <table border="1" cellspacing="0" bordercolor="#FF0000">

        <tr>

          <td>[b2.$;block=tr;p1=[b1.$]]</td>

          <td>

            <table border="1" cellspacing="0" bordercolor="#00FF00">

              <tr>

                <td>[b3.val;block=tr;p1=[b1.$];p2=[b2.$]]</td>

              </tr>

            </table>

          </td>

        </tr>

      </table>

    </td>

</tr>

</table>

And the php:

<?

//Here is an example with data stored into a Php array like:

//   $src['A'] = array('a1'=>'a1-1');

include_once('tbs_class.php');

$TBS = new clsTinyButStrong;

$TBS->LoadTemplate('levels3.htm');

$src = array (

'A' => array (

    'a1' =>array('a1-1','a1-2'),

    'a2'=>array('a2-1','a2-2')

    ),

'B' => array (

    'b1' =>array('b1-1','b1-2'),

    'b2'=>array('b2-1','b2-2')

    ),

'C' => array ('c1' =>array('c1-1','c1-2'),'c2'=>array('c2-1','c2-2'))

);

$TBS->MergeBlock('b1','array','src');    //string syntax

$TBS->MergeBlock('b2','array','src[%p1%]');

$TBS->MergeBlock('b3','array','src[%p1%][%p2%]');

$TBS->Show();

?>

Hope you can tweak this into a solution for your problem.

Re: sub-block indexing error? Re: MergeBlock() with array of arrays (with inner numeric indexes)

Pirjo,
Thanks for pushing me onward!

The example you provided also did NOT work after I modified the template to the same form as mine.
So after some many, many puzzled re-re-re-reading of the diff's I did see the simple error I was making. Solved.

Results (working!) now at http://tomhenry.us/tbs3/

Thanks for TBS,
TomH
