[SOLVED] Split strings from php and return values

JavaScript
1

Hello
I am trying to pass data from php to js and return the values like in the code. The problem I am facing is where I am testing I have hardcoded to values into a string in js and the code works fine. What I need to do however, is grab these values from php. I have tried various options such as var str = data; but it is not grabbing any data. I would be grateful if someone could point out my error. thanks

loadActions.php

<?php
  $brtvsql = "SELECT * FROM act WHERE activity='Box Retrieval' AND new = '1'";
  $result = mysqli_query($conn, $brtvsql);
  $brtv_row = mysqli_fetch_assoc($result);
  $count = mysqli_num_rows($result);
  echo 'brtv' . ' ' . $count;

  $brtnsql = "SELECT * FROM act WHERE activity='Box Return' AND new = '1'";
  $result = mysqli_query($conn, $brtnsql);
  $brtn_row = mysqli_fetch_assoc($result);
  $count = mysqli_num_rows($result);
  echo 'brtn' . ' ' . $count;
?>

js code

setInterval(function() {
  $.get('/domain/admin/loadActions.php', function(data) {
    var str = "brtv 30;brtn 0";
    console.log(data);
    var data = {};
    str.split(";").forEach(function(s) {
      data[s.split(" ")[0]] = s.split(" ")[1];
    });

    // Check the result
    if(data["brtv"]) {
      console.info("brtv: %s", data["brtv"]);
      $(".retrievals").text(data["brtv"]);
    }

    if(data["brtn"]) {
      console.info("brtn: %s", data["brtn"]);
      $(".returns").text(data["brtn"]);
    }
  });
}, 15000);

It was actually very simple. Just by changing to this. var str = data; Hope it helps someone else. Sorry should have posted solution. Cheers

FTR, you might find it easier to hand data over this way in JSON format and condense your queries into a single query:

  $brtvsql = "SELECT activity,COUNT(new) AS num FROM act WHERE new = '1' GROUP BY activity";
  $result = mysqli_query($conn, $brtvsql);
  $resarray = mysqli_fetch_array($result,MYSQLI_ASSOC);
  $dout = array();
  foreach($resarray['activity'] as $idx => $actname) {
     $dout[$actname] = $resarray['num'][$idx];
  }
  echo json_encode($dout);

 $.get('/domain/admin/loadActions.php', function(data) {
      $(".retrievals").text(data["Box Retrieval"])
      $(".retrievals").text(data["Box Return"])
 });

EDIT: Wait… assoc works the other way around. need to pivot the table.
