Hello - I also found this extremely helpful; and it worked fine in Flash Builder 4.
I added a little to the output to also pass back the userID, and wanted to see if there is any follow up on Diego's ? - Is it safe?
thanks

My apologies to Mr. Neri. I finally managed to make it work. Now the only challenge is to incorporate this log in system in my project.

Anyway, Thank you Mr. Neri !!!! This is a big help.

I am afraid this tutorial is out of date and it should be removed. I spent three days trying to make it work on Flex 4 ... with no avail. I am sure it worked well for earlier versions or someone with enough knowledge can make it work. But again, this is for newbies like me, the guys who know better .... they look elsewhere.
Or if Mr. Neri can update the scripts would be great.
Thank you.

BTW, this is a tutorial example only, I know. But, do you think this is secure? How can I add security? is necessary?
I mean, if for example, I set up a variable that says 'logged' is enough to keep application security and use this variable for protected data, etc.

Thank you

Very Very Nice!
rocks
Thx

Hi, any idea how to create user system in Flash Builder 4?

hi every thing is gud but we use zenframe work creates problem .

i whan to open free login here

It's Good for Beginners.......

I myself put this tutorial on the Adobe Cookbooks website for marketing purposes, no need for flaming gentlemen :)

@Lame
Dude use ur brain this tutorial is from 2006 year, the link that u give is from January 8, 2008.
Cookbook from adobe is for posers, they steal tutorials from net and post there

Dude, way to steal the tutorial from flex cookbook. You could at least make a reference to it, and the fact that it's not your work.
Here's the REAL one if anyone is interested:

Thank you soo much! I have been trying to create this for a few days now and this tutorial worked great.

This is really cool, I'm wondering whether you could show us how to do this program with ActionScript only (without using MXML except the few lines of it, and without the Design tools). Thanks for the tutorial anyway. I really like it.

Very nice.
Since I use ASP instead of PHP I had to mess around with the code......worked first time around.....SUPER!

Nice start for me thanks, but my prob is...

at my localhost, all are perfect as in all... but then I transfered the files from the output folder to my shared web hosting account which has the same features as mine... Is there something to modify in the files or what? I have no idea coz I can't login the accounts and there's no even alert box popping up for invalid accounts.

I run the login.php file and no mysql errors or something different, it outputs the value of the $output variable which is of course 'no' so I don't know if there's something blocking the way (the files) or server problem?

Any help guys? oh and btw I'm new to flex and still learning PHP :D

Nice tutorial very helpfull!

Thank you

I've did all that this tutorial is doing, but when i did on submit button with url
url="http://www.vipercreations.com/site_admin/login.php".
work fine.

But when i point to localhost the status line says waiting for localhost.

There is something that i am doing wrong.

Hello, great tutorial. I was wondering if this would work with url="j_security_check". I've been playing around with it for a while, and can't get it to work. Any ideas?

Example:
id="login_user"
result="checkLogin(event)"
showBusyCursor="true"
method="POST"
url="j_security_check"
useProxy="false">

{j_username.text}
{j_password.text}

I'm a newbie to php, but where in the world does the php script go?????

I've been trying to get your tutorial on how to
Create a Login System with Flex and PHP to work.

I have it working when I use your code:
url="http://www.vipercreations.com/site_admin/login.php".

But when I point to my local host I do not get an error, status line says waiting for localhost.

my question is where are you putting the checkLogin file and what is inside of it?

I have brought in the exact source code, but tied it to my own mysql database that matches what you setup, but I keep getting this error when I hit "submit".

ReferenceError: Error #1069: Property loginsuccess not found on String and there is no default value.

Hi, nice example. How can I do to carry the authenticated user to a second html page?

Thank for this great tutorial. Helped me out a lot. But how do I pass the variables of this user to the next state? If I want for example the name of the user (a Welcome, John Doe) on the logged in state. How do I do this? I have a firstName column in my database.

Ok took me 2 days to install everything: apache webserver, mysql, php, and follow this tutorial to the end.

I have a working DB with example data, and the connection is good. When I run the login.php file alone in my browser it gives me the NO for a succesfull login.

I think something is wrong with the submit button. I suspect it doesnt activate the login file? I did put in the onclick text... but it doesnt give me an error, and I dont know why. Anybody suggestions why I cant get it to work?

thanks again,
John

Thanks a lot for your great help.

There is one mistake
we should use
import mx.rpc.events.ResultEvent;
to use ResultEvent

Add this line like this
" import mx.rpc.events.ResultEvent;
private function checkLogin(evt:ResultEvent):void
....
...
....
..
"

Hello, very nice example. Thank you very much.

I am a PHP developer and trying to learn FLEX using flex builder 3. I followed all the your mentioned steps but on saving the mxml file it is giving me error

Severity and Description Path Resource Location Creation Time Id
1046: Type was not found or was not a compile-time constant: ResultEvent. login/src login.mxml line 19 1231840726421 25


The code for that line is
private function checkLogin(evt:ResultEvent):void

Can you help me in this please?

Thanks in advance.

Best regards,
Harshal

Very nice

Great and simple. thx.
I have a problem though in that I have changed it slightly to include an @ in front of the mysql_connect and added in a conversion of the password using the SHA1 function. However when I try to enter the credentials I get a 2032 Stream error using URL http://localhost/login.php. I have included header changes in the login.php as follows;
header('Pragma: bogus');
header('Cache-control: bogus');

but I still get the error. Very new to flex and PHP so I am not sure how this is not working. Webserver is Apache 2. Hopefully you might be able to shed some light on the subject.

Worked Perfectly!!!

Many thanks from Brazil my brother, Im a PHP programmer and learning Flex and Im very happy on how its easy to work with databases.
If anybody wants I send my project by email explaining more.... Disponivel tambem para a galera Brazuca que se interessar.

Hi, i got a problem with apache, its crashed when i activate the login.. plz help

Great tutorial, I have it implemented, and working fine. But I am curious as to how you would pass a userid variable from one state to another. Like in straight PHP you can set a SESSION_ID which will allow you pass a few variables from page to page.

I would like to pull to a datagrid/mysql on the "Logged In" state, that is assosciated with the user

ie: SELECT * FROM users WHERE userid = $_POST['userid'];

or something similar. I am at a loss as to how to pass this variable from the base state to the logged in state.


HELP!!!!!!

Thank you, Thank you, Thank you.

Awesome tutorial. I really appreciate for this effort to.

Gr8 job. Pls continue post like this tutorial.

Thanks
sridhar

Nice

Example of your crossdomain.xml file, please!!!

Thx 4 the nice tutorial!!

Where can i change the username + password (like us:test pass:test). I connect to my database, but can't figure out, where the username and password is stored. Connection is good, because the:mx.controls.Alert.show('Invalid username/password'); popup.

Beautiful tutorial, I finally realize how to partially utilize my PHP!!

Hey great tutorial. Got it working well. How would I go about having the login on an application so that when a user logs in they are then able to edit information (say in the form of text) and it is saved in the database so next time they log in they can see what they had written earlier. A complex question i know but i am trying to develop an app kind of like really simple blogging software. Any insight would be greatly appreciated thanks.

yeah this tut is nice... but its useless for people that dont know anything about database....it would me so much helpfull if u would also show how to create the database and table....because my script works now... just i dont know anything about database and mysql...i dont know how to add users and create the tables :>
would be happy if someone answers

Hi,

this sample helped me so much in building a login page with php, really good...

Good mini tutorial!!!.. Thanks for your time

from Chile

Dear sir,
I am very new to flex development and i have created the charts using this xml data but i was just struck in doing using mysql data and php which the output will be in xml could please help on this ....

It's really good & easy to understand & apply. I'm impressed. Thanx..........

is it possible to run the application from my desktop (mac) and put the HTTPService url on a web host server that has PHPmyAdmin (with mysql) on it.

I followed the tutorial of gotoandlearn.com (thanks Marty), and used your PHP file, though for some reason, I think everything is working fine except the fact that when I click the php file I get an error, which you can find at http://yozef.quotaless.com/login.php
error: [code=SERVER_RESPONSE_CLOSE]

Maybe it's from the server, I put the php file in the root, and I suppose I left:
define( "DATABASE_SERVER", "localhost" );

cheers

Since completing the tutorial as shown i have set up an apache server to act as my local host for testing purposes. I have also created the database called 'flex' with a table called users with fields: username, password and loginsuccess.

I have put sample data into the database.

The database and login.php are sat on the server in the same location and my http service url is pointing at the server.

When i run the app i get the following error:

Error #1069: Property loginsuccess not found on String and there is no default value.

any ideas...please help, i am a complete noob to all of this and trying to make sense of it all...

Thanks Daniel,
Thats helped me alot!
Adam.

Adam,

Take a look at this:
http://teamtutorials.com/web-development-tutorials/create-mysql-databse-with-cpanel-and-phpmyadmin

The database schema I used can be found here:
http://pastebin.com/936915

Hi,
I started this, then got confused and downloaded yours. I copied the source from yours, and overwrited mine and I've noticed that when here-


your login.php is pointed here-

http://www.vipercreations.com/site_admin/login.php

-
So I changed the above from http://www.vipercr... just to login.php - then got the PHP code from above and saved it as login.php

If you understood any of that, im just confused as to how I link up the login.php to my database? I'm using cPanel 11 and have the following software for Databases-

MySQLDatabases, MySQLDatabaseWizard, PHPMyAdmin, RemoteSQL, PostgreSQLDatabases, PostgreSQLDatabaseWizard and PHPPgAdmin.

Could you tell me how to link 'login.php' to a database, and how to actually create a database.

Thanks, Adam.

also can you tell me how to put this on my main application (so all gets loaded straight away), after copying get xml parse error
Parse error at ''. and how can I make a simple registration system (+ required db tables etc) to accompany it?

thanks for the tutorial but can you tell me how to setup/populate the db correctly (required tables etc) to work like yours?

Tabetan,

I've never really tried to decompile one of the swfs but I'll take a look at that right now and see what happens :)

I have a very lamer question.
If the swf gets decompiled is it possible to access private areas of the application??
And if want to avoid this, does anybody know a solution?

Tom,

I replied to your post in the forums :)

Aaron - I'll see what I can do as far as getting another Flex tutorial up. They're quite the laborious thing to do anyway!

This is the BEST flex/php tutorial available. PLEASE do more things Flex :)

chrispem,

Try using parentDocument.currentState, I've used that before in a component and it worked.

Or you could dispatch an event or something...

Hi, I have packaged the login into its own component and want the login to change the main applications currentState but when I call currentState it says it cant find it. Guess its looking in the component for the state. How can I tell it to reference the parent Application?

ueon,

You have to have Flex Builder 2 installed, and you place it under the "Flex Builder 2" folder which, by default, is in My Documents.

This is if you want to edit the files as a project in Flex Builder.

You then have to import the project, in Flex Builder click File->Import or something similar and then import and existing project.

Note: you might have to create the following files for it to show up as a project in Flex - ".project",".flexProperties",and "actionScriptProperties".

Notice there is nothing before the period!

Hope that helps :)

where do you put the code?

GREAT, GREAT, GREAT tutorial. I got it working in under five minutes and I suck at flex. Really, thank you for doing this. It has clarified a lot of things related to logins, etc. For other noobs, note that I used two other flash-php-mysql tutorials:

gotoandlearn.com and hasan.otuome.com

Anyway, thanks for the tutorial, man. Please post more Flex-related things. You're really good!!

Hello from France, sorry my english, it's not so much, thanks very much for yours exemples, more educative. I begining with flex and i have the little problems with yours files download. You can giving the base Mysql use with your exemple files for learning. Thanks so lot :)

Rob,

I believe all the files located in the "bin" folder have to remain together, that is my understanding. It should work then, although you should check the link to your login.php script.

It seems that when I move the files out of the original directory that nothing happens when clicking the Login button. Any ideas what could be wrong?

The file has been updated!

You're right I haven't updated the file in the zip.

I'll get to it asap, should be done soon!

It seems the source file has not been updated as I still get the following error after downloading it:
Error #1009: Cannot access a property or method of a null object reference.
at Login_php/userLogin()
at Login_php/__Submit_click()

Did I do something wrong?

MD5 and SHA1 as classes - http://gsolofp.blogspot.com/2006/01/actionscript-3-md5-and-sha1.html

Just wanna ask about the way the password being sent to the server.. I see that it's sent by plain text and not encrypted? am I missing something? if am right.. how can I encrypt it before sending it?

I've fixed the login bug on both the tutorial and the example.

Should be working fine now!

Ok, the code is unreadable, so visit he Adobe forum: http://www.adobe.com/cfusion/webforums/forum/categories.cfm?forumid=60&catid=585 and see the topic: "Flex Login with PHP Tutorial"

Nice tutorial, we need mor like these. The problem is that all RPC data service calls (RemoteObject, WebService, HTTPService) are asynchronous, meaning the code after the call does not wait for the dta to return, but continues to execute. You can never access the result of a call in the same function in which you invoke the send. You must either bind to lastREsult, or better, use a result handler function. Below is an example solution as created by Vygo on the Adobe Flex General Discussion forum Tracy private function userLogin():void { login_user.send(); } private function checkLogin(evt:ResultEvent):void { if(evt.result.loginsuccess == "yes") { currentState = "Logged In"; } if(evt.result.loginsuccess == "no") { mx.controls.Alert.show('Invalid username/password'); } } Vygo

Hey, Yes I've noticed that error. I just can't seem to figure out why, it has something to do with the web service.

Hello Nice example the first one that I can follow in try to mke user login with php but give me one error in the debugg the same error that give your live example. Only work on second click? TypeError: Error #1009: Cannot access a property or method of a null object reference. at Login_php/userLogin() at Login_php/__Submit_click()
