4. Create four input text fields on the Stage, and give them the following instance names:
emailFrom_txt , emailTo_txt , emailSubject_txt , and emailBody_txt .
5.
Create a dynamic text field on the Stage with the instance name debug_txt .
6.
Create a button symbol, drag an instance on to the Stage, and give it an instance name of
submit_btn .
7.
Select Frame 1 in the Timeline, and open the Actions panel (Window > Actions) if it isn’t
already open.
8. Enter the following code in the Actions panel:
this.submit_btn.onRelease = function() {
var emailResponse:LoadVars = new LoadVars();
emailResponse.onLoad = function(success:Boolean) {
if (success) {
debug_txt.text = this.result;
} else {
debug_txt.text = "error downloading content";
}
};
var email:LoadVars = new LoadVars();
email.emailFrom = emailFrom_txt.text;
email.emailTo = emailTo_txt.text;
email.emailSubject = emailSubject_txt.text;
email.emailBody = emailBody_txt.text;
email.sendAndLoad("http://www.yoursite.com/email.cfm", emailResponse,
"POST");
};
This ActionScript creates a new LoadVars object instance, copies the values from the text
fields into the instance, and then sends the data to the server. The CFM file sends the e-
mail and returns a variable (
true
or
false
) to the SWF file called
result
, which appears
in the
debug_txt
text field.
9. Save the document as sendEmail.fla , and then publish it by selecting File > Publish.
10.
Upload sendEmail.swf to the same directory that contains email.cfm (the ColdFusion file
you saved and uploaded in step 2).
11. View and test the SWF file in a browser.
