Poll - how to disable empty user input

Saturday 22 July 2006 10:17:18 am

The title says it all. I want to disable collecting informaation in poll when the user didn't input anything (e.g. no radio button was selected). The current behaviour of eZ in this case i to increase the number of votes, but not to include this vote in any answer. So the summ of all votes for each answer now doesn't match the total votes count.

Is it possible to disable this?

Nothing is impossible. Not if you can imagine it!

Hi Marko,

here's how I dealt with the issue:

1. Edit (or create) settings/override/collect.ini.append.php

In section
[CollectionSettings]
add
CollectionUserDataList[poll]=overwrite (was probably unique)

Then,

2. Edit the active ezoption.tpl file, removing the "checked" sections

Then,

3. Add JavaScript to the poll form so that a blank vote doesn't get sent.
For example,

<b>in poll form</b>
onSubmit="return validatePoll(document.pollForm.ContentObjectAttribute_data_option_value_{$poll.0.data_map.question.id})"

<b>in page head</b>
{literal}
<script type="text/javascript">
<!--
function validatePoll(rObj){
    for (var i=0; i<rObj.length; i++) if (rObj[i].checked) return true;
    alert("Please make a selection before voting.");
    return false;
}
//-->
</script>
{/literal}

It's dependant on JS, which makes it a cheap hack, but it gets the job done.
