It´s a simple start rating implemented with javascript. There´s no  
problem because I put it in public/javascripts and i can call them in my  
application.html.rb but there´s one problem. I have this in my view:

.  
.  
.

 " /\> 

```
    <input name="submit" type="submit" value="Votar" />
</form>

```

\<?php if(isset($\_POST)): echo("Value is: ".$\_POST["input-rating"]); endif ?\>

.  
.  
.  
I don´t know PHP, and I understant this lines:

\<?php if(isset($\_POST)): echo("Value is: ".$\_POST["input-rating"]); endif ?\>

Anybody that works with PHP too can says me the equivalence for rails??

Post parameters are available in the view via the params method. Are you  
seriously trying to put PHP code in your views? Or do you want to port  
the php to ruby?

I try with this:

\<%- if(isset($\_POST)): echo("Value is: ".$\_POST[“input-rating”]); endif  
%\>

but firefox shows me this error:  
SyntaxError in Videos#show

Showing videos/show.html.erb where line #17 raised:
