I'm using the code below to display a maximum of 16 items in 4 columns from "my own" rss feed.
My feed contains 30+ items.
Is there a way to modify the code so the page displays 16 random items from my feed - not just the first 16?
Thanks in advance!
<?php
require("MagicParser.php");
$ItemMax = 16;
$ItemCount = 0;
$columns = 4;
$current_column = 0;
function myRecordHandler($item)
{
global $ItemMax;
global $ItemCount;
global $columns;
global $current_column;
print "<td style='font-size:11px;' align='left' valign='top' width='220'>";
print "<h2><a href='".$item["LINK"]."' target='_blank'>".$item["TITLE"]."</a></h2>";
print $item["DESCRIPTION"];
print "</td>";
$current_column++;
if ($current_column == $columns)
{
print "</tr><tr>";
$current_column = 0;
}
$ItemCount++;
if ($ItemCount==$ItemMax) return TRUE;
}
{
$url = 'http://www.domainname.co.uk/rss-feed.rss';
// start the table
print "<table cellpadding='10' width='748'>";
print "<tr>";
// parse the URL to generate each result in a table cell (myRecordHandler does this)
MagicParser_parse($url,"myRecordHandler","xml|RSS/CHANNEL/ITEM/");
// end the table
print "</tr>";
print "</table>";
}
?>
Hi,
Try something like this:
<?phprequire("MagicParser.php");
$ItemMax = 16;
$ItemCount = 0;
$columns = 4;
$current_column = 0;
$items = array();
function myRecordHandler($item)
{
global $items;
$items[] = $item;
}
$url = 'http://www.domainname.co.uk/rss-feed.rss';
// start the table
print "<table cellpadding='10' width='748'>";
print "<tr>";
// parse the URL to generate each result in a table cell (myRecordHandler does this)
MagicParser_parse($url,"myRecordHandler","xml|RSS/CHANNEL/ITEM/");
shuffle($items);
foreach($items as $item)
{
print "<td style='font-size:11px;' align='left' valign='top' width='220'>";
print "<h2><a href='".$item["LINK"]."' target='_blank'>".$item["TITLE"]."</a></h2>";
print $item["DESCRIPTION"];
print "</td>";
$current_column++;
if ($current_column == $columns)
{
print "</tr><tr>";
$current_column = 0;
}
$ItemCount++;
if ($ItemCount==$ItemMax) break;
}
// end the table
print "</tr>";
print "</table>";
?>
Instead of displaying the output within myRecordHandler, this version loads all records into an array ($items) then shuffles the array; then displays the first $ItemMax records as part of the foreach loop...
Hope this helps!
Cheers,
David.
