I have 2 pages which is for a rating system with stars.

index.php

then the rating.php (does the functions)

<?php
include("dbcon.php");

echo $_REQUEST['id'];
$users_ip = $_SERVER['REMOTE_ADDR'];

	mysql_query( $query);

	$row=mysql_fetch_array($result);

	$rating=$row['rating'];

	$quer = mysql_query("select rating from ratings");
	$all_result = mysql_fetch_assoc($quer);
	$rows_num = mysql_num_rows($quer);
	if($rows_num > 0){
	$get_rating = floor($rating/$rows_num);
	$rem =  5 - $get_rating;
	}

	?>
	<?php echo $_get['id']; ?>
<?php
	for($k=1;$k<=$get_rating;$k++){?>
	<div class="rating_enb" id="<?php echo $k?>"> </div>
	<?php
	}?>
	<?php
	for($i=$rem;$i>=1;$i--){?>
	<div class="rating_dis" id="<?php echo $k?>"> </div>
	<?php
	$k++;
	}?>	
	<div class="rating_value"><?php echo ((@$get_rating) ? @$get_rating : '0')?>.0 (<?php echo $rows_num?>)</div>

<?php
}
else
{
	echo '<div class="rating_message">You have already Voted for this product!!</div>';
}
}
if(@$_REQUEST['show']) // show rating again after showing message
{
$result=mysql_query("select sum(rating) as rating from ratings");
$row=mysql_fetch_array($result);

$rating=$row['rating'];

$quer = mysql_query("select rating from ratings");
$all_result = mysql_fetch_assoc($quer);
$rows_num = mysql_num_rows($quer);
if($rows_num > 0){
$get_rating = floor($rating/$rows_num);
$rem =  5 - $get_rating;
}?>
<?php

<?php

}?>	
<div class="rating_value"><?php echo ((@$get_rating) ? @$get_rating : '0')?>.0 (<?php echo $rows_num?>)</div>
<?php
}?>

the script finds my ip address fine, and the value is forwarded and both added to my database.

what i wanted to add onto this is an id number in the URL.

namely "rating.php?ID=47" this is then going to be inserted into the db in the rating.php file.

can someone help me code this please?

you appear to have everything you need already in your code? are you getting an error of some kind? or the result isn't what you expect it to be? What exactly is the issue you're having?

WebStyles · August 11, 2011

if you're adding &id=xx, then

echo $_REQUEST['id'];

will work.

if you're adding &ID=xx

then you need to use uppercase:

echo $_REQUEST['ID'];

The Script works fine, i wanted to make the stars script work on multiple products, so i added "product_id" column to my database.

i can pass a url such as index.php?ID=XX but i am not sure how to alter the above code to pull the id from URL, pass it through the script and eventually add the product_id to the database.

WebStyles · August 11, 2011

(..) but i am not sure how to alter the above code to pull the id from URL (..)

Just gave you that solution. Use $_REQUEST or $_GET

jacko_162 · August 11, 2011

i tried:

$pid = $_GET['ID'];

in index.php, but i couldnt echo this or could i pass this onto rating.php

WebStyles · August 11, 2011

can also post the following:

1. how you called the url. (the complete string please)

2. what's the name of the file where you have that code

3. the part where you actually echo that variable.

thank you

jacko_162 · August 11, 2011

if you see my first post i have the 2 pages needed "index.php" and "ratings.php"

i then typed index.php?ID=47

and in index .php i have the following:

im actually not sure where and how it calls rating.php i assume its in the javascript, of which i have NO clue..

i need to pass the ?ID=47 to rating.php and from there i assume i need to use the $_GET and insert the result into the "product_id" column in Database.

WebStyles · August 11, 2011

you need to pay more attention. you said you tried:

$pid = $_GET['ID'];

but that's NOT what you have. (see why I wanted you to post your code again?)

this:

$pid = $_get['ID'];

should be:

$pid = $_GET['ID'];

(UPPERCASE)

jacko_162 · August 11, 2011

haha always the easy things, now i have the $pid variable sorted in index.php, how do i edit index.php to pass this onto rating.php?

then i can add it into the INSERT.

Thanks WebStyles o/

AyKay47 · August 11, 2011

concatenate it onto a querystring to rating.php..

jacko_162 · August 11, 2011

managed to blag it by adding a second variable in the javascript and adding it to the URL string...
