PHP Code Get Most Recent Wordpress Post
This is a quick example using only vanilla PHP. There are more dynamic ways to do this using RSS classes built into PHP addons, which I won’t go into detail here. Instead, we will just use vanilla PHP, and parse the XML by hand.
On to the code, I take 3 arguments here, number of posts to return, the RSS URL, and an optional max number of characters to return.
//get most recent rss //get most recent rss function recent_rss($display=0,$url='', $description_limit = 0) { $itemArr = array(); $doc = new DOMDocument(); $doc->load($url); foreach ($doc->getElementsByTagName('item') as $node) { if ($display == 0) { break; } $description = $node->getElementsByTagName('description')->item(0)->nodeValue; //if limit passed in, truncate string if($description_limit > 0) { $description = substr($description, 0, $description_limit)."..."; } $itemRSS = array ( 'title' => $node->getElementsByTagName('title')->item(0)->nodeValue, 'description' => $description, 'link' => $node->getElementsByTagName('link')->item(0)->nodeValue, 'pubdate' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue ); array_push($itemArr, $itemRSS); $display--; } return $itemArr; } //example use $recent_post = recent_rss(1, 'http://houseplansblog.nelsondesigngroup.com/index.php/feed/', 0); var_dump($recent_post); |
Now, Here is a quick and dirty XHTML example showing how you might implement this on a page. (Note the use of the preg_replace to get rid of weird characters that get into the RSS sometimes)
<div id="rss_container" style="width:250px;"> <div id="rss_title"> <a href='<?php echo $recent_post[0]["link"]; ?>'> <?php echo preg_replace('/[^(\x20-\x7F)]*/','', $recent_post[0]["title"]);?> </a> </div> <div id="rss_pub_date"> <?php echo $recent_post[0]["pubdate"];?> </div> <div id="rss_description"> <?php echo $recent_post[0]["description"];?> </div> </div> |
