SimpleXML Object is not passed to view

#1

Hi there,

I hope that someone has the answer to my problem :-)

I'd like to pass a simplexml object from my controller to my view. Here's the code:
Code:
function loadxml($url)
    {
        $curl_handle=curl_init();
        curl_setopt($curl_handle,CURLOPT_URL,$url);
        curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,3);
        curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
        return curl_exec($curl_handle);
        curl_close($curl_handle);
    }

    function Index()
    {
        $url = 'http://some-site.com/myData.xml';
        $xmlLoading = $this->loadxml($url);
        $xml = simplexml_load_string($xmlLoading);
        $outputarray = array();
        if ($xml) {
            foreach ($xml->Auctions->Auction as $auction) {
                array_push($outputarray, $auction);
            }
        }
        $this->load->view('header');
        $this->load->view('listing_view', $outputarray);
        $this->load->view('footer');                              
    }

The XML is correctly loaded and the $outputarray has the correct data are it. Still I get a "undefined variable" in my view :-( Can't I transfer such an object?

I also tried to pack everything into an array as described here: http://codingforums.com/showthread.php?t=87283 and it didn't work either.

Thanks for help me out.

Can we see your view?

Also, in the loadxml function, you're returning before you close curl. You can't do that. The close_curl function is never getting called.

Hi Raiko,

Thanks pointing out my error in the loadxml function.

Here's my little class:
Code:
<?php  if (!defined('BASEPATH')) exit('No direct script access allowed');

class Listing extends Controller {
    function Listing()
    {
        parent::Controller();
    }
    function loadxml($url)
    {
        $curl_handle=curl_init();
        curl_setopt($curl_handle,CURLOPT_URL,$url);
        curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,3);
        curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1);
        return curl_exec($curl_handle);
        curl_close($curl_handle);
    }
    
    function Index()
    {
        $url = 'http://www.ricardo.ch/Default/GetXMLListing.asp?catg=1&listingtype=7&listingsort=1&MaxPerPage=2';
        $xmlLoading = $this->loadxml($url);
        $xml = simplexml_load_string($xmlLoading);
        print_r($xml); // $xml is loaded correctly
        $outputarray = array();
        if ($xml) {
            foreach ($xml->Auctions->Auction as $auction) {
                array_push($outputarray, $auction);
            }
        }
        $this->load->view('header');
        $this->load->view('listing_view', $outputarray);
        $this->load->view('footer');                              
    }
}
?>

And here's my view:
Code:
<?php
print_r($outputarray);
?>

I get this error:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: outputarray
Filename: views/listing_view.php
Line Number: 2

I was having a similar issue until I embedded it into an array, like:

Code:
$process['xml'] = $xml = new SimpleXMLElement($data);

$this->load->view('index', $process);

Thanks for your help :-D

I finally found an answer:

I added this line:
Code:
$data['xml'] = $outputarray;

cheerio.
