Hi  
I have an existing php application running commercially…Now I have a  
new rails application…So I have three fields like user\_name ,password  
and company in the php page .Which when submitting connecting to my  
rails application …To elaborate  
suppose I enter

username= user1  
password = pass1  
company = company1

```
Then when submitting the php page it should goes to my rails

```

application on port 3000 This I could do…Similary if I give a different  
company name then it wii be connected to my rails application on port  
3001

```
   Now my request is if anything error happens for wrong password or

```

wrong company name (for example) I need to redirect from rails  
controller action to the php login page it self…This I dont know how to  
do…I am totally new to this type of interconnecting two  
platforms…Could you please help me to solve this problem

Thanks in advance  
Sijo

you must have some kind of authentication system in Rails app.

so after comparing posted values…

if user exists then redirect\_to “home/index” [home is controller and  
index action for rails app]  
else  
redirect\_to “[http://abc.com/login.php](http://abc.com/login.php)”

let me know
