Looking for options on how to do this. org chart as is doesn't work
because nodes have to be unique but as we know a function may have more
than one parent I create the array correctly but only the first use of the
node is displayed. Is there something more suited to do what I'm trying to
achieve.
<?php
/*echo "Item sent from post " . $_POST['parent'];*/
$node = $_POST['parent'];
$GLOBALS['i']=0;
$parent="";
function buildBranch($node, $con, $parent) {
$GLOBALS['branchcount']++;
$sql="SELECT Child FROM Links WHERE Parent='$node' ORDER BY
Child ASC";
$branch = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($branch)) {
$GLOBALS['i']++;
$GLOBALS['ROWS'][$GLOBALS['i']] = [$row['Child'],$node];
buildBranch($row['Child'],$con, $node);
}
}
include "connectDB.php";
mysqli_select_db($con,"mapping_demo");
$GLOBALS['ROWS'][$GLOBALS['i']] = [$node,""];
$GLOBALS['prevNode'] = $node;
buildBranch($node,$con,$parent);
mysqli_close($con);
$mySweetJSONString=json_encode($ROWS);
?>
<script type='text/javascript'
src='https://www.google.com/jsapi'></script>
<script type='text/javascript'>
google.load('visualization', '1', {packages:['orgchart']});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
var myArray = <?php echo "$mySweetJSONString"; ?>;
data.addColumn('string', 'Node');
data.addColumn('string', 'Parent');
data.addRows(myArray);
var chart = new
google.visualization.OrgChart(document.getElementById('chart_div'));
chart.draw(data);
}
</script>
