I'm hitting the wall for nearly two hours now, trying to figure this out.

Here is the thing' I have made a xml parser to read xml file and add posts (with content) from xml:

$ch = curl_init( "http://abc.xml" );

curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_HEADER, 0 );
$data = curl_exec( $ch );
curl_close( $ch );
$doc = new SimpleXmlElement( $data, LIBXML_NOCDATA );


$size = count( $doc );
$count_added = 0;
for( $i = 0; $i <= 1; $i++ )
{
    $img = $doc->prod[$i]->awImage;
    // skipping the part of post adding
    $my_post_id = wp_insert_post( $new_post );
    update_post_meta( $my_post_id, 'prod_image', $img );
}

Problem is that custom filed doesn't get my $img value, even though if I do echo $img - I get the content... Strange thing is if I create some other variable $var="test" and enter this instead $img in update_post_meta - the custom field gets the value of $test...

Whats wrong here, because I'm starting to hit keyboard really badly...

Regards.

Have you tried to set $img variable directly (I mean write it down by hand) to "$doc->prod[$i]->awImage" content and check if it is stored? –  JohnnyPea Sep 6 '11 at 12:57
    
You should also check if the post ID isn't already present, when inserting. –  kaiser Sep 6 '11 at 13:35

Maybe if you use add_post_meta instead, because update_post_meta assumes that you have already that value and you are updating it ( from http://codex.wordpress.org/Function_Reference/update_post_meta ).

Also check if $doc->prod[$i]->awImage is actually a string (do print_r instead of echo).

If a value isn't found, update_post_meta will insert it. "The first thing this function will do is make sure that $meta_key already exists on $post_id. If it does not, add_post_meta($post_id, $meta_key, $meta_value) is called instead and its result is returned." From the codex page you linked to. –  chrisguitarguy Sep 6 '11 at 16:47
    
Fair enough, maybe it's the loop value... what if dumps print_r($doc) to see if the problem is there? –  Álex Acuña Viera Sep 6 '11 at 18:16
    
thanks for the suggestion of print_r. the thing was this var was somehow SimpleXMLElement object and wordpress had problems with that, so what i did was - $img=strval($img); to return string from this value. –  kroma Sep 7 '11 at 7:14
