Fetch full posts content of FeedWordPress feeds

Hi :)

I use WordPress and FeedWordPress plugin to create a planet. It's great plugin. Some bloggers don't show full post content on their feeds. If you like to get the full content of posts, you can contact to blogger and ask his/her to enable full content on the feed or continue to read this article.
I create functions to get full content of posts.


  • PHP with cURL support (Client URL Library)

  • Permissions to modify theme files

  • Text editor

  • basic php programming skills

Step 1 - Where is post content?
It's easy. just open the web page and see the page source.
For example, open (Single post with full content) and see the page source.
On the page source you can see the content which is started by below code:
<div  class="postBody">

and ended by :

<div class="postFooter">

* It's not ended only by </div> because there is some divs on post content. So I add some html code after </div> which is unique.

Step 2 - Add started and ended code to `Custom Feed Settings`
Open the wordpress administration panel and go to the `Feed and Update Settings` page. Select the feed from drop down menu (Here `Saeid Zebardast's Blog`).
Add started and ended code to `Custom Feed Settings`:

Step 3 - Fetch full content from source and update post on wordpress
Open functions.php in text editor and add the below codes to the end of it:

function validLink($link) {
if(preg_match('|^http(s)?://[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(/.*)?$|i', $link)) {
return true;
} else {
return false;

* Get a web file (HTML, XHTML, XML, image, etc.) from a URL. Return an
* array containing the HTTP server response header fields and content.
function get_web_page( $url )
$options = array(
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers
CURLOPT_FOLLOWLOCATION => false, // follow redirects
CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_USERAGENT => " spider", // who am i
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects

$ch = curl_init( $url );
curl_setopt_array( $ch, $options );
$content = curl_exec( $ch );
$err = curl_errno( $ch );
$errmsg = curl_error( $ch );
$header = curl_getinfo( $ch );
curl_close( $ch );

$header['errno'] = $err;
$header['errmsg'] = $errmsg;
$header['content'] = $content;
return $header;

function before ($this, $inthat)
return substr($inthat, 0, strpos($inthat, $this));

function after ($this, $inthat)
if (!is_bool(strpos($inthat, $this)))
return substr($inthat, strpos($inthat,$this)+strlen($this));

function multi_between($this, $that, $inthat)
$counter = 0;
while ($inthat)
$elements[$counter] = before($that, $inthat);
$elements[$counter] = after($this, $elements[$counter]);
$inthat = after($that, $inthat);
return $elements;

function strbet($inputStr, $delimeterLeft, $delimeterRight, $debug=false) {
$posLeft=strpos($inputStr, $delimeterLeft);

if ( $debug ) {
echo $posLeft;

if ( $posLeft===false ) {
if ( $debug ) {
echo "Warning: left delimiter '{$delimeterLeft}' not found";
return false;
$posRight=strpos($inputStr, $delimeterRight, $posLeft);
if ( $posRight===false ) {
if ( $debug ) {
echo "Warning: right delimiter '{$delimeterRight}' not found";
return false;

if ( $debug ) {
echo $posLeft;
echo $posRight;

return substr($inputStr, $posLeft, $posRight-$posLeft);


Close functions.php and open single.php in text editor. Add the below codes after `<?php if (have_posts()) : while (have_posts()) : the_post(); ?>`:

$my_content = get_the_content();
if (is_syndicated()) :

$syndication_permalink = get_post_meta(get_the_ID(),"syndication_permalink", true);
$syndication_source = get_post_meta(get_the_ID(),"syndication_source", true);
$syndication_source_uri = get_post_meta(get_the_ID(),"syndication_source_uri", true);

if (!validLink($syndication_permalink) && validLink($syndication_source_uri)) {
$syndication_permalink = $syndication_source_uri . "/" . $syndication_permalink;

$post_updated = get_post_meta(get_the_ID(),"post_updated", true);
if (empty($post_updated) || $post_updated == false) {

$start_content = get_feed_meta('start_content');
$end_content = get_feed_meta('end_content');

if (!empty ($start_content) && !empty($end_content)) {
$result = get_web_page($syndication_permalink);
$my_page = $result['content'];

if (!empty($my_page)) {
$valid_texts = array();
$valid_texts = strbet($my_page, $start_content, $end_content);
if (is_array($valid_texts)) {
$valid_texts = $valid_texts[0];

if (!empty($valid_texts)) {
$my_post = array();
$my_post['ID'] = get_the_ID();
$my_post['post_content'] = $valid_texts;
$my_content = $valid_texts;
update_post_meta(get_the_ID(), 'post_updated', true);

endif; //is_syndicated()

After it, replace `the_content()` with:
 echo $my_content; 

Close text editor and Upload functions.php and single.php to your theme folder. Now go to the single post and see the full content.
Just try it!

  1. Hi, i was searching for something like this becouse I wamted to try feedwordpress with my 2 blogs' feeds (1 blog is the one which should be replicated and the other one is the testing blog). I did everything you explained but it doesn't work for me, I still get [...] and the content is cut. When I uploaded the files, functions.php gave me an error on line 1072 which is the line where your codes begins so I deleted the code "<?php" and it didn't give the error. But it still doesn't work. What can I do? Can you help me? If you want i can upload that php files and give it to you if it could be usefull.

    PS I know that it would work if i make the rss show the full content but i don't do that because i want it to work with other blogs' feeds which are cut like mine.

    PPS Sorry for my bad english I'm italian :)

    PPPS Feel free to mail me :D

    I tried this code and I think it needs to be altered for wp 3.1. I would really like to see how one would change this up for 3.1. If you have time, I know I would truly appreciate it.

  16. I've tried to get this working with the latest version of Wordpress, but I get an error after I change the "echo $my_content;" bit. Please help.

  17. Sorry, I don't use FeedWordPress plugin any more.

  18. Hi Please do have an alternatives to post full post content?

  19. I personally still use FeedWordpress quite a bit. But recently I found the need to get some more fine grained tools for things here and there. I wound up getting

    You can use it all by itself via short codes, or you can even integrate it directly with FeedWordpress via the key/value custom fields in combination with the Web Grabber short codes.

    I've found it to work really well for the simple fact that anyone using FeedWordpress isn't "only" trying to syndicate from other wordpress sites. And if there's anything you've learned from playing with FWP is that no two RSS feeds are alike, hehe

  20. Parse error: syntax error, unexpected T_VARIABLE in /home/tazehneg/public_html/wp-content/themes/Tazehnegar/single.php on line 34

  21. [...] Need to be aware that FeedWordPress can’t get content for partial rss feeds but plugins are available [...]
