PHP Simple not a object error

dnwk

Hi
Could someone look at this PHP code and see why the second addchild will generate an error " addChild() on a non-object"?
Thanks

$rtaXML = new SimpleXMLElement("<records></records>");

foreach($vas as $key=>$val){

$rtaBib[$key]=$rtaXML->addChild('bibrecord')->addAttribute('id',$key);

    foreach($val as $copy=>$item){
    $rtaBib[$key]->addChild('item');
    }

}
echo $rtaXML->asXML();

Here is the XML I am trying to build

 <record>
  <bibrecord>
    <item>
    something
     </item>
    </bibrecord>
  <bibrecord>
     <item>
      something
     </item>
   </bibrecord>
 </record>

The first addChild() is done on the $rtaXML object while the second one is not. The second one is attempting to be done on the $rtaBib array which is not an object.

php.net/manual/en/simplexmlelement.addattribute.php isn't returning anything meaning $rtaBib[$key] is not an object. I'm not sure what are you trying to do as that code doesn't make much sense to me, but you maybe wanted something like this:

$rtaBib[$key]=$rtaXML->addChild('bibrecord'); $rtaBib[$key]->addAttribute('id',$key);

Here is the XML I am trying to build. @vedran I am trying to add additional child and some element could be repeated like multiple bibrecord

 <record>
  <bibrecord>
    <item>
    something
     </item>
    </bibrecord>
  <bibrecord>
     <item>
      something
     </item>
   </bibrecord>
  </record>

Anyone has suggestions?

You will want to output the contents of $rtaBib[$key] and $rtaXML using var_dump(). Either of those is likely to be something different from what you expect it to be.

If I want to add a child on a child how to do that?
