Author Topic: State List disappears when Country chosen on dropdown (Read 1851 times)

leahb · July 12, 2009, 07:27:29 pm

On the frontend of our site, where contribution pages and event registration pages are. When 'United States' is chosen from the drop down list, the entire list of states goes blank so no state can be chosen (on the billing information section)

I have checked the localization and everything seems fine there. I have recently upgraded to 2.2.7 and this is the first glitch I have found.

Does anyone know what I am missing? The site is www.ncheroes.org
By accessing either the events register page or the Donate page, you will come across the error.

Thank you so much!

if you goto this url:

https://www.ncheroes.org/index.php?option=com_civicrm&task=civicrm/ajax/jqState&&_id=country_id-5&_name=country_id-5&_value=1228

and do a view source, you will see at the end:

Code: [Select]

<script type="text/javascript">
        var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
        document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"\
));</script><script src="tt_files/ga.js" type="text/javascript"></script>
<script type="text/javascript">
        try {
                var pageTracker = _gat._getTracker("UA-7581046-1");
                pageTracker._trackPageview();
        } catch(err) {}</script>

seems like this is being added by another joomla component/plugin (for google analytics) which messes up the json object

you can compare the output you get with the one we get on the demo machine:

http://drupal.demo.civicrm.org/civicrm/ajax/jqState?_id=country_id-5&_name=country_id-5&_value=1228

not that u'll need to do a view source to spot the differences

Ah ha - wonderful.

I disabled the plugin and everything is back in top shape.

I guess there is no way to run this plugin with CiviCRM huh? Any suggestions for a friendly google tracker?

Thanks so much Lobo!

for ajax queries we do an explicit exit from within civicrm code, so the tracker should not be adding that code.

sorry limited joomla experience, so dont know a lot about other modules/plugins

I'm troubleshooting a similar problem. I have pretty much removed any potential conflict-creating extensions, and the problem remains. What's weird is when I try to access the url to view the ajax query results, I get nothing. Empty page. Any ideas?

1. what does firebug tell u

2. is your url of the same format as the ones mentioned in this topic

ping me on skype/IRC and we can take a look

thanx

The problem with my install seems to be with JSON. The json_encode function simply isn't working -- it doesn't convert the array into that format. Any more ideas?

Donald Lobo · July 14, 2009, 07:11:54 am

what version of php?

u might want to write a small php script and see what json_encode returns for various parameter values

I was afraid you'd ask that. PHP 5.1.6.

I know that JSON was added to PHP 5.2. But it looks like you actually construct the JSON array manually in json_encode -- i.e. you're not using any existing libraries or builtin functions.

When I add debug statements to print the array, it displays fine. But I added echo statements to JSON.php encode function, right at the beginning, and they're never hit. It just dies when it gets to json_encode ($elements) (in CRM/Core/Page/AJAX/Location.php).

Well, problem was indeed that I'm running on 5.1.6 and json_encode is a native 5.2 function. I was able to create something of a workaround.

In CRM/Utils/JSON.php I've added the following function:

Code: [Select]

//modified version of function to be consistent with json_encode in php 5.2
    static function encodejson ( $params, $identifier = 'id' ) 
    {
        $buildObject = array( );
        foreach ( $params as $value ) {
            $name = addslashes( $value['name'] );
            $id = $value['value'];
            $buildObject[] = "{\"name\":\"$name\",\"value\":$id}";
        }
        $jsonObject = '[' . implode( ',', $buildObject) . ']';
        return $jsonObject;
    }

In CRM/Core/Page/AJAX/Location.php I've modified code so that it calls this new function instead of json_encode:

Code: [Select]

//echo json_encode( $elements );
echo CRM_Utils_JSON::encodejson( $elements );

There's about a dozen instances of json_encode used throughout Civi (including another instance in the Location.php file, I believe). So they would all need to be modified to reference the new function.
