    Hi,
    I followed the other posting instructions re parameter passing with the following code snipett

    add_shortcode( ‘introduction’, function($atts){

    $locn = $atts[“locn”];
    $output = “”;
    $output .= ‘<h1>Assessment Planner – ‘.$locn.'</h1>’;
    $output .= ‘<table id=”chance”><tr><td style=”width: 12%”>% Chance:</td><td><span id=”legendContainer” class=”legend” style=”border-style: solid; border-color: threedface; width: 100%”> </span></td></tr></table>’;

    return $output;
    });http://localhost/risk/wp-admin/edit.php?post_type=page

    and get the following error report

    Warning: Illegal string offset ‘locn’ in H:\sites.web\risk\wp-content\plugins\code-snippets\php\snippet-ops.php(446) : eval()’d code on line 3

    The shortccode on the page is

    [introduction locn=”UNITED KINGDOM”]

    It works fine without reference to $atts[“locn”] in line 3 and $locn in line 5

    Any suggestions?

    Thanks

    Paul

    You should be using the shortcode_atts function to ensure that all attributes are present before attempting to access them. Change the first line of the snippet to this:

    add_shortcode( 'introduction', function ( $atts ) {
    $atts = shortcode_atts( array(
        'locn' => '',
    ), $atts );

    Hi,

    Thanks for the quick response. I’ve made the change and I no longer get the error message but the passed parameter is not being picked up.

    The line $output .= ‘<h1>Assessment Planner – ‘.$locn.'</h1>’; just produces “Assessment Planner – ” without UNITED KINGDOM.

    Thanks

    Paul

    Glad to hear, Paul – might have been a caching issue.
