Part 4 - Telling the script which Ecard to display - and passing variables to the EcardThis script is the one that the Link in the email points to. When the user clicks on the link this script will open up. Depending on the value of the two attached variables it will act in a certain way. The below script is part of "SelectCard.php". The most important thing to realize is what this script is actually doing. All that it is doing is dynamically setting up the <object> and <embed> code for the Ecard. In this way we can embed a specific ecard depending on what the user choose. Remember that $Enum has the same value as EcardSelect from the original Flash movie. The below 'Switch' Statement is just like an If-then statement, only easier to read for this case. The switch statement uses cases to determine which set of instructions to follow. If ENum is equal to 1 (this would be the case if the user choose Ecard 1) then it will execute the first statement block. The most important part of this is that it sets the $goto variable to Ecard1.swf. This later embeds that movie into this page. The normal <object> and <embed> code for the flash movie acts more like a template in this case. This also attaches a variable onto the end of the Ecard1.swf string. This variable corresponds to the filename where the custom text for this movie is located. By attaching this variable onto the end of the embed string it is automatically declared inside the flash movie. Their is also an option for including a footer file that will allow the person viewing the card to send the same card to someone else - You can leave this portion out without any problems if needed. We also set the dimensions of each flash Ecard we are sending out in this statement block. They happen to all be the same in this example, but depending on the dimensions of the E-Cards you are using you may want to change these for all or for each individually. <?
switch ($ENum) {
case '1':
$goto = "Ecard1.swf?EcardText=".$EcardText;
$gotoFooter = "EcardFooter.swf?EcardText=".$EcardText."&EcardSelect=1";
$Dimensions = "WIDTH=700 HEIGHT=525";
$DimensionsFooter = "WIDTH=700 HEIGHT=250";
break;
case '2':
$goto = "Ecard2.swf?EcardText=".$EcardText;
$gotoFooter = "EcardFooter.swf?EcardText=".$EcardText."&EcardSelect=2";
$Dimensions = "WIDTH=700 HEIGHT=525";
$DimensionsFooter = "WIDTH=700 HEIGHT=250";
break;
case '3':
$goto = "Ecard3.swf?EcardText=".$EcardText;
$gotoFooter = "EcardFooter.swf?EcardText=".$EcardText."&EcardSelect=3";
$Dimensions = "WIDTH=700 HEIGHT=525";
$DimensionsFooter = "WIDTH=700 HEIGHT=250";
break;
case '4':
$goto = "Ecard4.swf?EcardText=".$EcardText;
$gotoFooter = "EcardFooter.swf?EcardText=".$EcardText."&EcardSelect=4";
$Dimensions = "WIDTH=700 HEIGHT=525";
$DimensionsFooter = "WIDTH=700 HEIGHT=250";
break;
case '5':
$goto = "Ecard5.swf?EcardText=".$EcardText;
$gotoFooter = "EcardFooter.swf?EcardText=".$EcardText."&EcardSelect=5";
$Dimensions = "WIDTH=700 HEIGHT=525";
$DimensionsFooter = "WIDTH=700 HEIGHT=250";
break;
}
?>
//This is regular html with PHP mixed in - the php that is mixed in is determined by the above script.
Notice how we use the variable from above to dynamically change what swf is embeded. This is most apparent with the $goto variable. You can see that we write small pieces of php code after for example the 'src=' line - Then we use the variable $goto from above to change what is embedded depending on what card the user choose.
