[Solved] JSON Parse Error [Syntax Error]

Postby alaoa » Sat Feb 28, 2009 11:59 pm

I spent hours on this and I feel like kicking my self. I'm just posing this for others who run into this issue. If your are getting this error

Code: Select all
Open Flash Chart

JSON Parse Error [Syntax Error]
Error at character 0, line 1:

0: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://


then your not encoding the url.

if your using php make sure you call the urlencode() function for the "data-file" var.

I second that. This should be added to the Tutorial:

Here's code that works:

Code: Select all
<?php
$startDate = '2009/2/20';
$clientID = '1005';

$daturl = urlencode("/report/all_conversions.php?date=".$startDate."&clientid=".$clientID);
?>

<script type="text/javascript" src="/report/ofc/js/swfobject.js"></script>
<script type="text/javascript">
swfobject.embedSWF(
  "/report/ofc/open-flash-chart.swf", "all_conversions_report", "950", "150",
  "9.0.0", "expressInstall.swf",
  {"data-file":"<?php echo $daturl; ?>"}
  );
</script>

<div id="all_conversions_report"></div>

I am encoding the URL and still getting that error in IE, at least I think it is that error, but everything works just fine in FF. I am Stumped!!! and would love some help

The charts work just fine in Firefox.

This is my JSON string as rendered by Firebug in Firefox on an AJAX call

The JSON looks good. Can you post the code which loads the chart?

OK, so I have spent more time debuggin this!

Things work fine for me with this in IE, but when I wrap this wihtin an iframe as an application in Facebook I get an intermitten JSON error that I listed above.

Now if I load app as a Facebook Connect app first, then the SWF loads just fine within FB

If I load FB first, I get the Javascript/JSON error.

Sounds like cross-site scripting prevention... I think there was some information on the forums about setting flash so you can do that...

It is possible, it works with FF, which is the weird thing and it works intermittently with MSIE...

I will keep digging, sounds like there isn't an easy answer

Re: JSON Parse Error [Syntax Error]

Now, I'm aware that my issue probably is that I'm not urlencoding it properly. The thing is I have no clue how to do it properly. On my page I don't receive an error message, but the video doesn't load. The JSON looks to be pulling all the data correctly, I've tried to follow any steps I could find but am frankly,... lost.

When I leave it like this;

<head>

<script type="text/javascript" src="/derek/js/swfobject.js"></script>
<script type="text/javascript">

swfobject.embedSWF(
"/home/jstarace/zardozthegreat.com/open-flash-chart.swf", "handletime",
"400", "300", "9.0.0", "expressInstall.swf",
{"data-file":"/derek/derekmetrics.php"} );

swfobject.embedSWF(
"/Users/derek/open-flash-chart.swf", "sales",
"400", "300", "9.0.0", "expressInstall.swf",
{"data-file":"/derek/dereksales.php"} );

swfobject.embedSWF(
"/Users/derek/open-flash-chart.swf", "csat",
"400", "300", "9.0.0", "expressInstall.swf",
{"data-file":"/derek/derekcsat.php"} );

</script>
</head>

Nothing loads - but there's also no error messages

But if I change it to;

<?php

$daturl = urlencode("/derek/derek.php);
?>

<head>

<script type="text/javascript" src="/derek/js/swfobject.js"></script>
<script type="text/javascript">

swfobject.embedSWF(
"/home/jstarace/zardozthegreat.com/open-flash-chart.swf", "handletime",
"400", "300", "9.0.0", "expressInstall.swf",
{"data-file":"<?php echo ?daturl; ?>"} );

swfobject.embedSWF(
"/Users/derek/open-flash-chart.swf", "sales",
"400", "300", "9.0.0", "expressInstall.swf",
{"data-file":"/derek/dereksales.php"} );

swfobject.embedSWF(
"/Users/derek/open-flash-chart.swf", "csat",
"400", "300", "9.0.0", "expressInstall.swf",
{"data-file":"/derek/derekcsat.php"} );


</script>
</head>

I get

Parse error: syntax error, unexpected T_STRING in /home/jstarace/zardozthegreat.com/derek/derek.php on line 8

Who knows it may just be that this is my first 12 hour stint working on a site and I can't think. But if you could please help that would be fantastic. Oh yeah and assume I know nothing... cause I don't :D

derek.php has an error on line 7 or 8. You're probably missing a semicolon or something...
