Hi, 
I have written a feed reader for my personal use. 
The php code given below does work. 
But it works only with a single feed. 
How can I save multiple cookies (array?) and display a few more RSS feeds.
The example page can be found at...
http://shantanuoak.com/test1.php 

<?php
if ($delete==yes) {
setcookie ("FeedCookie5", $formfeedurl1,time()-3600);
}
if (isset($_COOKIE['FeedCookie5'])) { ?>
<script language="javascript" src="http://forever.p3k.org/rss/rss-box.r?url=<?php 

echo "$FeedCookie5"; 

?>&align=left&width=300&frameColor=black&titleBarColor=%23add8e6&titleBarTextColor=

black&boxFillColor=white&textColor=black&fontFace=&maxItems=7&compact=&xmlButton=&j

avascript=true"></script>

<form action="test1.php">
        <input type="text" name="formfeedurl1" size="26">
        <input type="submit" name="Add" value="Add Feed">
</form>
<a href="test1.php?delete=yes">Delete Cookie</a><br>Please referesh the page

<?php
exit;
}
{
setcookie ("FeedCookie5", $formfeedurl1,time()+3600);
}
?>

<form action="test1.php">
        <input type="text" name="formfeedurl1" size="26">
        <input type="submit" name="Add" value="Add Feed">
</form>
<a href="test1.php?delete=yes">Delete Cookie</a><br>Please refresh the page

Thanks

Hi shantanuo-ga ,  
 
There are two ways to do what you want.  
 
The first is to store an array in the cookie, this can be done easily
with serialize(). However I would steer away from storing potentially
large volumes of data in a single cookie.
 
The second and possibly better option is to store a number of cookies,
and reconstitute them into an array within your software.

My code is a bit verbose, and could be done better, but it
demonstrates the principle well. By having predictable cookie names,
it is easy to handle them.
 
I hope that answers your question. Let me know if any of my code is
unclear to you.

Hi
Thanks for answer. The purpose of posting a question was not to learn
array cookies, but to use it to solve my problem. If you can write
such a perfect code, you can also edit the code mentioned above! :)
1. I want to know how many cookies are set. So the columns required
are total number of cookies + 1. (after adding the cookie(0))
2. I want to fill those different columns depending upon the values
set in the cookie.
3. I want a single link to "Delete All Cookies".

Hi shantanuo-ga,

Done.

You have the variable $cookiecount, which contains the number of
retrieved cookies (which is now a maximum of 100).

You can pass "deleteall=yes" which will deleteall cookies. Or
"delete=$i" where $i is the ID of a cookie (to remove a specific one).
Or, "formfeedurl=$i" where $1 is a URL to add.

Hope that covers it.

Your marvellous code is worth a million dollars! Is it possible to
rate 6 stars or 8 stars instead of just 5?

I have an answer for this, but for some reason I have been unable to
post this through my ISP's proxy server. I am still trying.

Sycophant is experiencing technical difficulties and is unable to post
an answer or further comments at this time. Rather than keep you
waiting, he has asked that I post his answer for him.

-K~

Thank you knowledge-seeker, 

I have posted my answer above. Hopefully this way if shantanuo-ga has
any problems I can be notified through the normal channels of any
clarification requests.
