public $dom2;
public function __construct(){
$this->dom = new simple_html_dom();
$this->dom2 = new simple_html_dom();
}
function GetDatumInUroPodatkovInTabKrajev($lang){
$this->dom->load_file("http://www...diferentadresthenbelow...html");

//some code...
//some code...
return $this->functon2("minkjaaa");
}
function functon2($ik){
$this->dom2->load_file("http://www.arso.gov.si/vreme/napovedi%20in%20podatki/vreme_si.html");
$tabelaVremRazm = $this->dom2->find('table[#class="online"]'); // this line trows an error, becaus dom2 is empty
return"";
}
}
?>

[Fatal error: Call to a member function find() on a non-object in C:\..\simple_html_dom.php on line ..]

Answer 1

Find("SELECTORS", index) Find returns an array of objects unless an optional index is specified, then it will return the Nth object... This is probably what you're missing... Here's a working example:
// includes Simple HTML DOM Parser
include "simple_html_dom.php";
$url = "http://www.arso.gov.si/vreme/napovedi%20in%20podatki/vreme_si.html";
//Create a DOM object
$dom2 = new simple_html_dom();
// Load HTML from a string
$dom2->load_file($url);
// Find the link with the appropriate selectors
$table = $dom2->find('table.online', 0);
// Find succeeded
if ($table)
echo $table->outertext;
else
echo "Find function failed !";
// Clear DOM object (needed essentially when using many)
$dom2->clear();
unset($dom2);
