if I use {{$node[0]->url}}
then Laravel's templating engine dislays the correct result but I can not figure out how to display all using the @for $i=0 within a @foreach loop this is what I have in my routes file
$oReturn = new stdClass();
$fid='endpoints';//sample fid
$url = 'http://localhost:5493/sdata/$system/registry/'.$fid;
$xml = simplexml_load_file($url);
foreach($xml->xpath("//sdata:payload") as $entry) {
// xpath here must be from payload to endPoint--type
$content = $entry->xpath("./sdata:endPoint--type");
foreach($content as $c) {
// Make set of children with prefix sdata
$nodes = $c->children('sdata', true);
}
// add parsed data to the array
$oReturn->entry[] = $nodes;
}
return View::make('index', compact('oReturn'));
and this is what I have tried in my view file
@for($i=0; $i < 4; $i++)
@endfor
@foreach ($oReturn as $node)
<li>{{$node[$i]->url}}</li>
@endforeach
sorry here is the complete print_r result

The simple answer is that foreach
in Blade works the same as a regular PHP foreach
. You should be able to do something like:
@foreach ($nodes as $node)
<li>{{ $node->url }}</li>
@endforeach
If you need access to the array key value for each node:
@foreach ($nodes as $key => $node)
<li>{{ $key }}: {{ $node->url }}</li>
@endforeach
However, I think the problem may not be with your Blade syntax, but with the way you created your input variables. Given the way you created $oReturn
in the code above, it won't have the properties you appear to be expecting. To illustrate, here's a simplified version of what you appear to be creating:
// initialize your return variable
$oReturn = new stdClass();
// create a dummy array <sdata:x> nodes,
// to simulate $nodes = $c->children('sdata', true);
$node = new SimpleXMLElement('<sdata:x/>');
$nodes = [ $node, $node, $node ];
// simulate adding nodes to the array of entries
$oReturn->entry[] = [ $node, $node, $node ];
// print out the resulting structure
print_r( compact( 'oReturn' ) );
would return:
Array(
[oReturn] => stdClass Object
(
[entry] => Array
(
[0] => Array
(
[0] => SimpleXMLElement Object()
[1] => SimpleXMLElement Object()
[2] => SimpleXMLElement Object()
)
)
)
)
So when you do @foreach ($oReturn as $node)
the value of $node
would be the entry[]
array, which has a single element, that is an array of nodes. It is not clear from your input that these nodes even have url
elements. If you did want to loop through the nodes you'd have to do something like:
@foreach ($oReturn->entry[0] as $node)
<li>{{ $node->url }}</li>
@endforeach
Does this make sense? I think you need to rethink your creation of $oReturn
.
Given feedback below and the output of your print_r
statement above, the following should work:
@foreach ($oReturn->entry as $node)
<li>{{ (string) $node->url }}</li>
@endforeach
The (string)
casts the result of $node->url
to string. Otherwise PHP may treat it as some kind of object. SimpleXMLElement
can be weird.
