In the last piece on our PHP online user poll, we look at the administrative service and how the site supervisor enters, deletes and manages the poll data.

The first poll administrative page checks if the administrator is logged in. You can choose from Session variables or Cookies to check the site administrator login status.

Once the application has confirmed the identity of the site administrator, the page lists the available polls.

The first step is to use the class methods and variables in the class.polls.php file:

<?php require_once("class.polls.php");

The next steps include instantiating the poll object and retrieving the poll data:

// instantiate polls class $oPolls = new polls; // get polls and poll count $aPolls = $oPolls->getPolls("created_dt desc", $iCursor); $iCnt = $oPolls->getPollsCount();

We create an array to hold and display the data from the polls table in the database:

// check for polls if (count($aPolls)) { // build page data array $i = 0; while ($i < count($aPolls)) { $aData[$i]["Id"] = $aPolls[$i]["Poll Id"]; $aData[$i]["Name"] = $aPolls[$i]["Question"]; $aData[$i]["Status"] = $aPolls[$i]["Status"]; $aData[$i]["Created"] =$aPolls[$i]["Created Date"]; ++$i; } }

For a given poll ID number, we can delete, activate or deactivate a selected poll:

// check for id if ($id) { // assign poll id $oPolls->setPollId($id); // check operation type if (!strcmp($op, "del")) { // try delete poll and redirect $oPolls->deletePoll(); header("Location: ".SELF); } elseif (!strcmp($op, "act")) { // try activate poll and redirect $oPolls->activatePoll();...
