First of all, thank you very much. SimplePie is easy to use and install, works great.
However, I can't find my way around.
I am using the Multiplefeeds add-on.
Say that I would like to get the latest posts from 3 different feeds, I have right now the following code:
foreach ($feed->get_items(0, 5) as $item) {
It display the 5 latest posts from the 3 feeds.
But I would like to get instead the 15 latest posts, it could be 8 from feed #1, 4 from feed #2, 3 from feed #3.
What would be the code to use instead ?
I hope I made myself clear.
Thank you very much for your help
Phil

I haven't tested this code yet, but it's a slight modification to the code from index.php from the multifeeds demo.
<?php
/*****************************************************************
PREPARATION AND PROCESSING
*****************************************************************/
// Be sure to include SimplePie.
require_once('simplepie.inc');
// Create my list of feeds to use
// I've checked that all of these feeds have per-item dates
$myfeeds = array();
$myfeeds[] = 'http://rss.news.yahoo.com/rss/topstories';
$myfeeds[] = 'http://news.google.com/?output=rss';
$myfeeds[] = 'http://digg.com/rss/containertechnology.xml';
$numberofitems = array();
$numberofitems[] = 8;
$numberofitems[] = 3;
$numberofitems[] = 4;
// This will be used to store and sort the feeds by date
$multifeeds = array();
// Keep track of which feed we're on
$count = 0;
// Go through each feed in the above array, parse it, and add specific chunks of data to the $multifeed array
foreach($myfeeds as $url) {
// Set your own configuration options as you see fit.
$feed = new SimplePie();
$feed->feed_url($url);
$feed->cache_max_minutes(30);
$feed->replace_headers(true);
$feed->init();
// We're going to loop through the items in the feed; starting at the beginning, and returning a max of 10 items.
for ($x=0; $feed->get_item_quantity($numberofitems[$count]); $x++) {
$item = $feed->get_item($x);
/*
* We're going to take data from the $item and put it together into a single string, delimiting each chunk
* with five colons (you can delimit however you want, but it's unlikely that you'll come across five
* consecutive colons in the content of a feed).
*/
// Start with a blank slate
$data = '';
// We're going to start with milliseconds since Unix epoch (this is the datestamp that we'll sort by)
$data .= $item->get_date('U') . ':::::';
// We'll choose a single timezone (GMT) to base all dates/times on.
$data .= gmdate('j M Y | g:ia \G\M\T', $item->get_date('U')) . ':::::';
// Get the title of the posting
$data .= $item->get_title() . ':::::';
// Get the permalink for the posting
$data .= $item->get_permalink() . ':::::';
// Get the description content for the posting
$data .= $item->get_description() . ':::::';
// Besides $item data, we'll also get the title of the $feed we're pulling this from
$data .= $feed->get_feed_title() . ':::::';
// Lastly, we'll get the permalink to the $feed that we're pulling this from.
// Since it's the last one, we don't need to add the delimiter to the end.
$data .= $feed->get_feed_link();
// Place this whole thing into the next available spot in the $multifeeds array.
$multifeeds[] = $data;
}
// We're done with $feed for this round of the loop, so we'll wipe it out so we can loop back and start fresh.
unset($feed);
// Increment the feed counter
count++;
}
// When we're done looping through the feeds and collecting our data, we'll reverse sort all of the feeds by seconds since Unix epoch (newest to oldest)
rsort($multifeeds);

I want to combine two feeds, and I want to display the 10 most recent items, regardless of where they come from.
If Source A has one post in two weeks and Source B has 15 posts in the last day, I want the output to be zero posts from Source A and 10 posts from Source B. If the posting schedule is exactly equal, I want five from each.
It won't matter to me how many items from each source are posted, I just want to have the 10 most recent. (I believe that's what the original question was asking, too -- not just a way to hardcode the number of items from each source). Will the Multifeeds add-on do this?

mattw -- the multifeeds demo is just some custom-written code that utilizes SimplePie to pull the latest items from multiple feed sources and display them.
What you can do is tell it to return the last 10 posts -- period -- and it will (of course, the feed posts must have a date associated with them in order to be able to sort properly).
In order to do what you're asking, get the latest multifeeds package (I tweaked it a bit a couple of days ago). Look for line 93 and change this:
foreach ($multifeeds as $posting) {... to this...
for ($x=0; $x<10; $x++) {
$posting = $multifeeds[$x];Doing do will limit the output to 10 items. They will be whatever the most recent 10 are out of all of the feeds pulled.
Hope this helps!

Skyzyx,
Thanks for the help -- that's exactly what I was looking for!
Not to press my luck, but I have a follow-up question to do something a bit more complex -- what's the most efficient way to display multiple blocks of multiple feeds?
That's probably a little confusing -- check out this URL to see what I'm talking about:
http://www.motorcityblogs.com
user: test1
pass: test1
Here's what I currently have above my header info:
$myAfeeds = array(
"tigers"=> "http://www.exampleA.com/feed/",
"lions"=>"http://exampleB.com/feed/",
"pistons"=> "http://exampleC.com/feed/"
);And later in my html I have this:
<div class="feedarea">
<br/>
<div class="title">
<h1><img src="images/title_A.gif"/></h1><br/>
</div>
<div class="title">
<h1><img src="images/title_B.gif"/></h1><br/>
</div>
<div class="title">
<h1><img src="images/title_C.gif"/></h1><br/>
</div>
</div>
<div class="feedarea">
<?php
foreach ($myAfeeds as $team=>$url) {
$feed = new SimplePie($url, $cache);
if ($feed->data) {
echo '<div class="feed"> <span class="rsslink"> ';
$max = $feed->get_item_quantity(10);
for ($x = 0; $x < $max; $x++) {
$item = $feed->get_item($x);
echo '<a href="' . $item->get_permalink() . '">' . $item->get_title() . '</a>'
;
}
echo '</span></div>';
}
unset($feed);
}
?>
</div>What I'd like to do is add multiple feeds to each team. Using the solution you provided above, I'm guessing I could do this with a nested array inside $myAfeeds, right?
Is this too complex for you to quickly show me how it'd be done? If so, could you point me in the right direction of a general PHP tutorial that might be applicable? As you might have guessed, I'm only a couple of weeks into teaching myself PHP -- I really appreciate all of the help I've received by reading this forum and your other tutorials.

Is the above possible now? If so how?

Yes, this is exactly what the multifeeds code is intended to do.

I'd like to try Skyzyx' solution from 29 August 2006, but don't see this line:
foreach ($multifeeds as $posting) {The nearest thing in my code is this:
foreach($feed->get_items(0,1) as $item):
I use SimplePie version "Razzleberry" (1.0.1). Not sure if the 2006 solution still applies.
I've tried to use the suggested code by replacing some words, but couldn't get it to work. I don't know PHP. The problem may just be a { or : or ;

First of all, what are you trying to accomplish?
Secondly, have you seen the 5th minimum requirement for using SimplePie?
