This is probably really easy and I'm probably gonna kick myself up the arse after this, but I have the following code which displays either html or json of data from a table and returns it.
<?php
session_start();
$base = dirname(dirname(__FILE__));
include($base."/include/db.php");
global $conn;
$trees = [];
$treeBoxes = [];
if(isset($_SESSION['clientId'])) {
$clientId = $_SESSION['clientId'];
$query = $conn->prepare("SELECT * FROM ct_trees WHERE client_id=?");
$query->bind_param('i', $clientId);
$query->execute();
$result = $query->get_result();
if($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
$tree_id = $row['id'];
$tree_name = $row['name'];
$query = $conn->prepare("SELECT id FROM ct_connections WHERE tree_id=?");
$query->bind_param('i', $tree_id);
$query->execute();
$result2 = $query->get_result();
$connections = $result2->num_rows;
array_push($treeBoxes, '<span class="checkbox abc-checkbox abc-checkbox-success">',
'<input id="tree'.$tree_id.'" type="checkbox" rel="'.$tree_id.'">',
'<label for="tree'.$tree_id.'">'.$tree_name.'</label>',
'</span>');
array_push($trees, ["id" => $tree_id, "name" => $tree_name, "connections" => $connections]);
if(isset($_GET['json'])) {
echo json_encode($trees);
} else {
echo join("", $treeBoxes);
}
}
}
}
?>
Now let's say for example, we want the json result, I'm getting the following string:
[{"id":1,"name":"My Tree","connections":4360}][{"id":1,"name":"My Tree","connections":4360},{"id":4,"name":"Another Tree","connections":0}]
Now for some reason, it's giving me the first result in one array, and then the same result, but with the other rows, in a separate array.
