Using Flash with php Very quick introduction to Flash Homework: work on projects

Challenge want Flash for 'flashy' front end Need server to hold permanent (persistent) information –database! –Flash to/from php

Set up database (table) modification of createfavorites table Also need to put initialize –insert 4 records, with 0 for votescast Write stand-alone php scripts –display results –re-set votescast fields to zero

$fields = "can_id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY, candidate char(50) NOT NULL, votescast INT NOT NULL"; createtable($tname, $fields); $query = "INSERT INTO votes VALUES (0,'Bush',0)"; $result = mysql_db_query($DBname,$query,$link); $query = "INSERT INTO votes VALUES (0,'Kerry',0)"; $result = mysql_db_query($DBname,$query,$link); $query = "INSERT INTO votes VALUES (0,'Nadar',0)"; $result = mysql_db_query($DBname,$query,$link); $query = "INSERT INTO votes VALUES (0,'Other',0)"; $result = mysql_db_query($DBname,$query,$link); mysql_close($link);

Flash graphics, text fields, components on Stage –Dynamic text fields –Input text fields –radio buttons (grouped) –push button with event handler specified ActionScript –function to respond to push button –function invoked upon return from server script

Flash as front end LoadVars() sets up object to be used for variables to and from server script sendAndLoad is a method of a LoadVars object

Frame Action var connect = new LoadVars(); function gotoserver() { // This Tells the Flash movie What function to invoke when the Load Vars Is complete. connect.onLoad = getback; connect.data = president.getvalue(); connect.sendAndLoad("addtoresults2.php", connect, "POST"); }

Upon return from script function getback() { display.htmlText = connect.display; } where display is the text field. Limited number of HTML tags

Flash to php The variable (data) is passed to the script. Data is passed back by setting &display –considered a property of the connect object

<?php $data= $HTTP_POST_VARS['data']; $host="localhost"; $user="curley"; $password="12345"; $DBname="firstdb"; $link=mysql_connect($host,$user,$password); print "&display="; $query = "UPDATE votes SET votescast = votescast+1 WHERE candidate = '".$data. "'"; $result = mysql_db_query($DBname,$query,$link); $query = "SELECT * FROM votes"; $result = mysql_db_query($DBname,$query,$link); while ($row=mysql_fetch_array($result)) { print " "; print $row["candidate"]; print ": "; print $row["votescast"]; print " "; } ?>
