I try to modify the page
/com_community/helpers/head.php
that I send you. Il problem is I cannot load the variable $bulletin->message
I write at line 137
// Setup Announcement Table $bulletin->load($act->cid); message title
// Moficica Setup Announcement Table
$bulletin = JTable::getInstance('Bulletin', 'CTable');
$bulletin->load($act->cid);
echo " Test ";
echo $bulletin->message;
echo " Fine test ";
$stringa=$bulletin->message;
$pos1 = strpos($stringa, '<img src=');
//identifico la prima occorrenza di apertura del tag immagine
$pos2 = strpos($stringa, 'g" />', $pos1);
//identifico la prima occorrenza di chiusura del tag jpg
$testo = substr($stringa,$pos1+10,$pos2-$pos1-9);
//estraggo il contenuto escludendo i tag iniziali
echo '<meta property="og:image" content="';
echo $testo;
echo '"/>';
but not working. thanks
