    So I added 2 rss feeds to one of my customers sites http://www.debbiedaanen.com and I managed to get everything modified to my liking except for one thing.

    Limiting the length (or number of characters) that display for my content.

    I was able to limit the number of characters for the title, and then placed a hellip at the end to signify the text was being cut off, but I can’t get it do the same for the content.

    Here is my code

    Code:
    Latest News

    set_feed_url($url);
    $feed->init();
    $feed->strip_htmltags(array(‘img’,’embed’,’strong’,’html’,’onclick’,’onmouseover’,’onmouseout’,’center’));

    // default starting item
    $start = 0;

    // default number of items to display. 0 = all
    $length = 1;

    // if single item, set start to item number and length to 1
    if(isset($_GET[‘item’]))
    {
    $start = $_GET[‘item’];
    $length = 1;
    }

    // set item link to script uri
    $link = $_SERVER[‘REQUEST_URI’];

    // loop through items
    foreach($feed->get_items($start,$length) as $key=>$item)
    {

    // set query string to item number
    $queryString = ‘?item=’ . $key;

    // if we’re displaying a single item, set item link to itself and set query string to nothing
    if(isset($_GET[‘item’]))
    {
    $link = $item->get_link();
    $queryString = ”;
    }

    // display item title and date
    echo ‘‘ . substr($item->get_title(), 0, 35) . ‘…‘;
    echo ‘‘.$item->get_date(‘M j, Y’). ‘‘;

    // if single item, display content
    if(isset($_GET[‘item’]))
    {
    echo ‘ ‘.$item->get_content().’
    ‘;
    }
    echo ‘
    ‘;echo $item->get_description();
    }

    ?>

    set_feed_url($url);
    $feed->init();
    $feed->strip_htmltags(array(‘img’,’embed’,’strong’,’html’,’onclick’,’onmouseover’,’onmouseout’,’center’));

    // default starting item
    $start = 0;

    // default number of items to display. 0 = all
    $length = 1;

    // if single item, set start to item number and length to 1
    if(isset($_GET[‘item’]))
    {
    $start = $_GET[‘item’];
    $length = 1;
    }

    // set item link to script uri
    $link = $_SERVER[‘REQUEST_URI’];

    // loop through items
    foreach($feed->get_items($start,$length) as $key=>$item)
    {

    // set query string to item number
    $queryString = ‘?item=’ . $key;

    // if we’re displaying a single item, set item link to itself and set query string to nothing
    if(isset($_GET[‘item’]))
    {
    $link = $item->get_link();
    $queryString = ”;
    }

    // display item title and date
    echo ‘‘ . substr($item->get_title(), 0, 35) . ‘…‘;
    echo ‘‘.$item->get_date(‘M j, Y’). ‘‘;

    // if single item, display content
    if(isset($_GET[‘item’]))
    {
    echo ‘ ‘.$item->get_content().’
    ‘;
    }
    echo ‘
    ‘;echo $item->get_description();

    }

    ?>

    When I try to apply the same logic I used for my title to the content it makes my content disappear. So my current solution was just placing it in a div with overflow:hidden on the stylesheet, but being the php noob that I am… I would love to know why applying the same logic from the title to the content didnt work, and how I could make it work.

    Ok so I am still working on things as I posted this, and I somewhat fixed my problem. I did manage to limit my content characters, but now I need to fix it so that it doesn’t cut off words.

    … If I manage to get it working I will post the code for others.

    You should look into using PHP to truncate the string by words:
