Oh I see, thanks for pointing out that.
Changed the path now to
C:\Program Files\Apache Group\Apache2\htdocs\poll\current.txt
Although the fopen() echo test yields a "SUCCESS", nothing shows up on the script. One interesting thing I noted is that when loading the page in IE, the whole page except the poll shows up, and the progress bar at the bottom shows that the page is still loading. Tried waiting for a few minutes but there was little progress. That doesn't happen for the fopen() test however.
Here's the code hexpoll.php
<?php

and the code for showing the poll:
<?php
require_once('hexpoll.php');
$questionTemplate = "<div style=\"text-align:center;margin-left:10px;margin-right:10px;\">[QUESTION]</div>";
$optionTemplate = "<ins style=\"margin-left:10px;\"><input type=\"radio\" name=\"vote\" value=\"[OPTION]\" />[OPTION]</ins>\n";
$poll = new HexPoll();
$poll->setPollFile('C:\Program Files\Apache Group\Apache2\htdocs\poll\current.txt');
$poll->setQuestionTemplate($questionTemplate);
$poll->setOptionTemplate($optionTemplate);
$poll->setQOSeparator('/');
$poll->setOVSeparator('|');
$poll->showPoll();
?>
and the code to show the results:
<?php
require_once('hexpoll.php');
$resultTemplate = <<<ENDOF
<div class="bold">[QUESTION]</div>
<ins><hr style="color:#CCCCCC;width:300px;position:absolute;left:0px;top:30px;" /></ins>
<ins><br /></ins>
<ins><br /></ins>

</table>
ENDOF;
$resultOptionTemplate = <<<ENDOF2

ENDOF2;
$poll = new HEXPoll();
$poll->setPollFile('C:\Program Files\Apache Group\Apache2\htdocs\poll\current.txt');
$poll->setResultTemplate($resultTemplate);
$poll->setResultOptionTemplate($resultOptionTemplate);
$poll->setGraphMaxLength(150);
$poll->setQOSeparator('/');
$poll->setOVSeparator('|');
$poll->showPollResults('vote','hasvoted');
?>
'vote' is the value of the name attribute in the radio buttons,
'hasvoted' is the value of the name attribute of the hidden form field to check if the user has voted
And in case you're wondering, the poll file format is something like this:
"Is 2005 a memorable year for you?"
/
Yes|28
No|14
