So I’m having some issus with JSON. 

setupdata({"NON-RELIGOUS ORGANIZATIONS":{"23":["NON-RELIGOUS ORGANIZATIONS","Does this Loce test 2","",null]},"YARD SALES":{"1":["YARD SALES","yard sale","1332599400",null],"22":["YARD SALES","LOCKING TEST YARD SALE a change and more","1331814600",null],"21":["YARD SALES","Generic Yard Sale Title","",null]}})

And I’m processing it with…. 

function setupdata(data){

   alert(data.length);
   for(i=0; i<data.length; i++) {
   newdiv = document.createElement("DIV");
   newdiv.setAttribute("id","cat"+i);
   newdiv.innerHTML(\'test\');
   document.getElementById(\'divmiddle\').appendChild(newdiv);
   }
 }

I’m getting UNDEFINED for the data.length and also the i loop is not running because it is undefined. I guess I’m just a bit confused about how to parse through the data I return from the JSON call. Any help apppreciated.

AND THE WINNING ANSWER IS

Creating the Arrays in PHP:

while($getcats = mysqli_fetch_array($query)){
$layout[$getcats[news_cat_name]];
if(!$getstories = mysqli_query($connection,"SELECT news_id,news_title,news_organization,news_expiration from news_items where news_category='$getcats[news_cat_id]'")){ echo mysqli_error($connection);}
while($looptitles=mysqli_fetch_array($getstories)){

$layout[$getcats[news_cat_name]][$looptitles[news_id]][]=date("m/d/y G:i a",$looptitles[news_expiration]);

 $layout[$getcats[news_cat_name]][$looptitles[news_id]][]=$looptitles[news_title];

$layout[$getcats[news_cat_name]][$looptitles[news_id]][]=$looptitles[news_organization];

}
}

AND THE RESULTANT JSON

setupdata({"NON-RELIGOUS ORGANIZATIONS":{"23":[false,"Does this Loce test 2","2"]},
"YARD SALES":{
     "1":["03\/24\/12 10:30 am","yard sale","0"]
     ,"22":["03\/15\/12 8:30 am","LOCKING TEST YARD SALE a change and more","0"],
     "21":[false,"Generic Yard Sale Title","0"]}})

AND THE JS to PARSE THE JSON

for(var key in data){//OUTER LOOP FOR THE MAIN OBJECTS
  divkey = document.createElement("DIV");
  divkey.setAttribute("id",key);
  divkey.style.fontSize = \'13px\';

  divkey.style.textDecoration = \'underline\';
  divkey.style.paddingTop = \'3px\';
  divkey.style.paddingBottom = \'5px\';
  divkey.style.position = \'relative\';
  divkey.innerHTML = key;
      document.getElementById(\'divmiddle\').appendChild(divkey);

  for(var mykey in data[key]){//INNER LOOP FOR THE INNER OBJECTS
         divkey = document.createElement("DIV");
     divkey.setAttribute("id",mykey);
         divkey.style.fontFamily = \'Verdana\';
         divkey.style.fontSize = \'11px\';
     divkey.style.paddingBottom = \'5px\';

     divkey.style.position = \'relative\';
     divkey.innerHTML = +data[key][mykey][1]+\' -- \' + data[key][mykey][0];
         document.getElementById(\'divmiddle\').appendChild(divkey);
   }
  }
 }
