    trouble accessing data object via page controlls Link to this post


    I'm trying to set up a page modifying the example in tutorial 5, but now I got stuck... I'd really appreciate if someone could help me out...

    So, I extended the data object like this:

    class Teacher extends DataObject {

    static $db = array(
    'FirstName' => 'Text',
    'LastName' => 'Text',
    'Email' => 'Text',
    'PersonalInfo' => 'Text'

    static $has_one = array(
    'MyTeacher' => 'TeacherPage',
    'Photo' => 'Image'

    function getCMSFields_forPopup() {
    $fields = new FieldSet();
    $fields->push( new TextField('FirstName', 'Vorname'));
    $fields->push( new TextField('LastName', 'Nachname'));
    $fields->push( new TextField('Email', 'Email'));
    $fields->push( new TextAreaField('PersonalInfo', 'Persönliche Informationen'));
    return $fields;

    Then I created a page in order to contain all this information:

    class TeacherPage extends Page {

    static $db = array();

    static $has_many = array(
    'MyTeachers' => 'Teacher'
    function getCMSFields() {
    $fields = parent::getCMSFields();

    $tablefield = new HasManyComplexTableField(
    array( 'FirstName' => 'Vorname',
    'LastName' => 'Nachname',
    'Email' => 'Email',
    'PersonalInfo' => 'Persönliche Infos'),
    $tablefield->setAddTitle( 'Lehrer' );
    $fields->addFieldToTab( 'Root.Content.Lehrer', $tablefield);
    return $fields;

    The cms looks just fine and I can add all the information that I want. But when I'm trying to display all this information, I run into troubles... I don't know how to access the data, correctly... I thought it was supposed to look like this.

    <div id="TeachersList">
    <% if MyTeachers %>
    <% control MyTeachers %>
    <div class="TeacherInfo">
    <h3>$FirstName $LastName</h3>
    <% end_control %>
    <% else %>
    nothing found
    <% end_if %>

    That all looks fine. What trouble are you having? Ie, what does it display?
