I've added a logging system to my vxml application but it only works when a form is filled out correctly (i.e. no nomatch or noinput events thrown). I'm trying to figure out a way to get it logging noinput and nomatch events as well.

I log by calling a subdialog which submits data into a database. I want to use subdialog rather than submit because I would like the existing vxml to continue after the logging is done. Unfortunately the subdialog tag can only occur in a form tag and this is what I'm having trouble working around.

Consider the following vxml snippet

Code: Select all

<form id="form_1">
    <field name="yn" type="boolean">
        <prompt>Say yes or no.</prompt>
        <error>
            <assign name="log_next" expr="'#form_1'" />
            <assign name="log_type" expr="'error'" />
            <assign name="log_name" expr="???" />
            <assign name="log_value" expr="???" />
            <goto next="#log" />
        </error>
        <filled>
            <assign name="log_next" expr="'#form_2'" />
            <assign name="log_type" expr="'normal'" />
            <assign name="log_name" expr="'yn'" />
            <assign name="log_value" expr="yn" />
            <goto next="#log" />
        </filled>
    </field>
</form>

<form id="form_2">
    ...
</form>

<form id="log">
    <subdialog .... />
    <goto expr="log_next" />
</form>

Firstly, in the error tag how do I determine the type of event and how do I determine the count of that event. I would like to put those values in place of the '???'s.

Secondly, this approach to logging errors doesn't really work since the event count will be reset when I leave form_1 to call the log form. If I could put a subdialog tag in the error tag that would be awesome... but since I can't I have to think of another way to do this.

I could maintain my own variables for event counts but I'd rather not duplicate that work. Is there a better way to go about this?

TIA

I just discovered the data tag. I've answered the second part of my post with that.

The documentation at http://www.plumvoice.com/docs/dev/ should be stickied! I found it by chance.

Hi Jonathan,

Generally, the IVR tag, <error>, is used for catching all types of IVR errors. So, if you wanted to specifically catch noinput or nomatch events, you should use the <catch> tag. For IVR example:

Code: Select all

 <catch event="noinput">
            <assign name="log_next" expr="'#form_1'" />
            <assign name="log_type" expr="'error'" />
            <assign name="log_name" expr="'noinput" />
            <assign name="log_value" expr="???" />
</catch>

This IVR post further shows the specific types of events you can catch so that you can properly log events:

As for keeping count for the events, the IVR tag, <catch>, has a "count" attribute so that you can keep track of how many times the event has happened. Or, alternatively, as you mentioned, you could use your own variables for event counts.
