Question

Here’s the code:

$.ajax({
 url:"http://.....pullEntireDBPopulation.php",
 cache:false,
 datatype:"json",
 success:function(popData){
  alert("Population size: " + popData.length);
  popProducers = new Array();
  for(i=0;i<popData.length;i++){
   popProducers[i] = popData[i].ProducerName;
  }
 });
}

I’ve written the .PHP to pull every piece of data from a database, which I’ve checked on the browser, so I know it’s not that. Still, every time I run the page, it says the array is around 5000 long even though that’s larger than the entire database. What’s going on???
If it helps, it’s also saying that when I write the data into arrays, they are undefined in the array. So there’s clearly a problem with the data being read into the page since I know it works on it’s own, but I can’t figure it out.

Answer 1

I found the problem. datatype: "json" apparently doesn’t render the same as dataType: "json" I hate when it’s stupid things like this! Because it wasn’t reading it as a JSON due to my capitalization error, it was just reading in a string rather than an array of objects–> problem.
