Hi!

I have made a new php-block to display Heise News at my geeklog site: http://miklas.dasburo.com. I want to include it as an existing php-site:

function phpblock_heisenews () {
global $_CONF;
$path = $_CONF['path_html'];
include_once($path . "/class.heise_news.php");
}

The Problem is: the nwe Heise News block is empty and showing up the news above my geeklog site ... please take a look at http://miklas.dasburo.com How can i fix that?

Thanx, Miklas

Your page must return the HTML string, NOT print the HTML. See any of the existing PHP blocks in GL and you\'ll see what I mean

The reason people blame things on previous generations is that there's only one other choice.

Your PHP block should return the contents of the block, not display the contents directly.

Not sure what your class does, but why don't you simply use the RDF file that Heise supplies (http://www.heise.de/newsticker/heise.rdf) and create a portal block instead?

Hi!

The portal block works, but then all the News were displayed. I want to
limit it to the last five news. here\'s the code of class.heise_news.php:

$list = new HeiseNews();
$list->setNumber(5);
$list->displayList();

class HeiseNews {
var $number = 0;

function setNumber($show_number) {
$this->number = $show_number;
return true;
}

function displayList() {
$cnt = \"\";
$this->liste = $this->retrNews();
while (list($key, $value) = each ($this->liste)) {
$cnt .= \"<li>\" . trim($value) . \"</li>\";
}
echo $cnt;
}

function retrNews() {
$fcontents = join (\'\', file (\'http://www.heise.de/newsticker/heise.rdf\'));
$fcontents = str_replace (\"</item>\", \"\", $fcontents);
$fcontents = str_replace (\"</link>\", \"\", $fcontents);

$splices = explode (\"<item>\", $fcontents);
if ($this->number) {
$show_splices = ($this->number + 1);
} else {
$show_splices = count($splices);
}

for ($i = 1; $i < $show_splices; $i++){
$link = explode(\"<link>\",$splices[$i]);
$link[1] = strip_tags($link[1]);
$headline = str_replace (\"<title>\", \"<a href=\\\"\" . trim($link[1]) . \"\\\"
target=\\\"_blank\\\">\", $splices[$i]);
$headline = str_replace (\"</title>\", \"</a>\", $headline);
$headline = explode (\"<link>\", $headline);
$headline = $headline[0];

$this->hdls[] = $headline;
}
return $this->hdls;
}
}

Here's a simple PHP block:

function phpblock_hello () { $retval = 'Hello, world'; return $retval; }

So what you need to do is rewrite your class so that it does not echo the news but returns them to your PHP block which then returns them (as a string) to Geeklog. Then they will show up in your block.

P.S. Do you know geeklog.info yet?
