Customized Rating Script - php help!

I don’t know how much information to give you right away, so I’ll just give a brief explaination first.
I’m using the Unobtrusive Ajax Star Rating Bar. It uses 4 php files, 2 js files, 1 css file, and 2 images, though I don’t think it’s as complicated as it sounds.
I’m using it here: http://www.themovietimeline.net/modx/index.php?id=15

My problem:
I want this script to be on all of my movie pages, but you have to give each script a unique ID. No problem. I figured I’d use a [+id+] placeholder in the snippet, but it doesn’t work when I do it that way.
My snippet looks like <?php echo rating_bar(’3’,’10’);?>. ’3’ is the id# and ’10’ is the number of units (stars) to be used. When I call it out like this, it works fine, but then I’d have to change the id number for every page.

A callout similar to this is what I need, and it almost works: <?php echo rating_bar(’[*id*]’,’10’);?> , but it won’t record the rating, as soon as I refresh it’s back to zero.

I also have another snippet callout at the top of each page <?php require(’_drawrating.php’);?>

I don’t know php at all, but in the _drawrating.php file it has a variables for the id like $id , $id_sent, and some other php code that I think might be messing it up, but I don’t know. Maybe someone experienced will just be able to look at this real quickly and figure out what’s wrong.

Can I use a placeholder in this instance? It won’t recognize any placeholder but the [*id*] one, so I’m not sure if it’s even understanding it as a placeholder?

Thanks in advance.

Something like this might work...

Something like this might work...

<?php
$docid = $modx->documentIdentifier;
$output = "rating_bar('{$docid}','10')";
return $output;
?>

Alright. I’ll give that a try. Thx

Sorry for the long delay. I haven’t been on since you replied.
I’m a little confused on where to place the code you suggested? Do I add that code to my main php script? Or in the snippet callout itself? If someone can help me out with this, I’d be happy to return the favor somehow!

All of my snippets references this _drawrating.php:

<?php
/*

My snippet code should replace your snippet code

My snippet looks like <?php echo rating_bar(’3’,’10’);?>

When I put your snippet in, it just came back blank with this text: rating_bar(’15’,’10’)

I took off the parenthesis like this:
<?php
$docid = $modx->documentIdentifier;
$output = rating_bar(’{$docid}’,’10’);
return $output;
?>

and it returned the rating slider, but when I voted it just sat there thinking forever?
Any ideas?

Damn. I wish I knew a damn thing about php! I finally learned css and a lot of html after 6 years of rebellion, but I’m glad I did. I just don’t wanna dive right into php. Somebody should really figure this out for me, or recommend a better rating script where I can change the image and number of units to suit. Just a thought.

what your ment to do is add the ratings db fields onto your main sites fields so instead of it being a table called ratings u take the fields inside there and put them with your video page fields then just change the php to link there.
