    Frage How to ignore current item in sidebar newslist?

    Hi,

    I've a very simple problem but don't know enough about Contao internals to code it...

    I have a newsreader that prints the item and a sidebar with all other current news stories listed in it. I want to exclude the item printed in full by the newsreader from the sidebar list so that you don't see it twice. I'm thinking it should be just a simple case of adding in an IF statement comparing the alias to the parameter supplied to the newsreader module, but I don't know how to write this, other than kludging it myself by looking at $_GET.

    Can anyone help?!!

    Thanks in advance

    Don't use $_GET within Contao. Use
    PHP Code:
    \Input::get('key');
    \
    Input::get('auto_item'); 
    You also can get page properties
    PHP Code:
    global $objPage;
    echo 
    $objPage-alias;
    dump($objPage); 
    Or with a Model (Maybe you will get some different values with $objPage and \PageModel. Consider that the news detail pages are not stored within DB.tl_page.)
    PHP Code:
    global $objPage;
    $pageModelObject = \PageModel::findByPk($objPage->id);
    echo 
    $pageModelObject->alias;
    dump($pageModelObject); 
    You also easily can find a news Model bei page alias
    PHP Code:
    $pageAlias = \Input::get('auto_item');
    $newsModelObj = \NewsModel::findByAlias($pageAlias);

    // Within your list template
    if($this->id === $newsModelObj->id)
    {

    All untested.

    Brilliant, thank you Andreas. That's enough info for me to figure out the rest on my own. Thanks for taking the time to explain this. Hopefully some other people will be helped too.

    You're welcome

    Edit: Oops, sorry, I forgot:
    PHP Code:
    $this->showTemplateVars(); // prints the template variables

    // or use this
    dump($this->arrData);
