I have generated the developer token in php and then passed it in javascript code in Iframe with the help of PHP variable.
Like this:
<?PHP
$apptoken = ....
?>
<body>
<button id="btnView">View Report !</button>
<div id="divView">
<iframe id="ifrTile" width="100%" height="400"></iframe>
</div>
<script>
(function () {
document.getElementById('btnView').onclick = function() {
var iframe = document.getElementById('ifrTile');
iframe.src='https://embedded.powerbi.com/appTokenReportEmbed?reportId=2d4210c6-be8b-4bf9-8cd4-134f99a0c1fa';
iframe.onload = function() {
var msgJson = {
action: "loadReport",
accessToken: "<?=$apptoken?>",
height: 500,
width: 722
};
var msgTxt = JSON.stringify(msgJson);
iframe.contentWindow.postMessage(msgTxt, "*");
};
};
}());
</script>
</body>
When I debugged the code I found that the token gets generated fine in PHP but when I access PHP variable in javascript code the value is not shown. The value is not transfered from appken to accessToken.
I think some where I am not properly using the PHP variable in javascript.
