    Hopefully someone can whip this newbie php’er into shape.

    I am trying to echo a foreach on an array inside an array but I am hitting a wall.

    The code
    <?php
$parentid = 315;
$tvidnames=gmapLatitude;
$myArray = $modx->getDocumentChildrenTVarOutput($parentid, $tvidnames);

print_r($myArray);

foreach ( $myArray as $key => $value){
	echo "<br /><br />Docid: $key $value <br />";
}
?>


    Which prints out
    Array ( [316] => Array ( [gmapLatitude] => 0.0 ) [317] => Array ( [gmapLatitude] => 0.0 ) [318] => Array ( [gmapLatitude] => 0.0 ) )

Docid: 316 (I want 0.0 instead and no Array at the end) Array
Would look like: Docid: 0.0

Docid: 317 Array

Docid: 318 Array

      change this:
      foreach ( $myArray as $key => $value){
	echo "<br /><br />Docid: $key $value <br />";
}


      to this:
      foreach ( $myArray as $doc => $m_value){
	foreach ($m_value as $x_key => $x_value)
	echo '<br /><br />Docid ('.$doc.'): '.$x_key.' '.$x_value.' <br />';
}


      good luck

      cheers

            How could I use this on going down the tree?

            This snippet works great on individual pages, I didn’t create it myself that goes to the wonderful modx developers reply in a forum.

            Current Page
            I can use this [[CustomSnippet]] which is great or any other place directly related to the specific page

            <?php
$output = '';
$myArray = $modx->getTemplateVarOutput(array('tv1','tv2'));
	if(empty($myArray['tv1'])){
	} else {
	$output .= '<h3>'.$myArray['tv1'].'</h3>';
	}
	if(empty($myArray['tv2'])){
	} else {
	$output .= '<h3>'.$myArray['tv2'].'</h3>';
	}
return $output;
?>

            The challenge.

            Trying to use it one above or two above.
            Parent Page using Ditto doesn’t appropriately associate the tv variable with the correct document ID.

            Resource container holding documents using Ditto

            Ditto $tpl=`ChunkName` &parents=`32`

            ChunkName = {{ [+pagetitle+] [[SnippetBelow]] }}
            <?php
$output = '';
$parent = $modx->documentObject[id];
$tvidnames=(array('tv1','tv2'));

$myArray = $modx->getDocumentChildrenTVarOutput($parent, $tvidnames);

$new=array_merge(array(),$myArray); // Used this because I couldnt find my around it show the Document ID = [id] of specific child id.

	if(empty($new[0][tv1])){
	} else {
	$output .= '<h3>'.$myArray['tv1'].'</h3>';
	}
	if(empty($new[0][tv2])){
	} else {
	$output .= '<h3>'.$myArray['tv2'].'</h3>';
	}
return $output;
?>
