Concrete 5.7 addon development

Permalink June 16, 2015 at 8:58 AM

I want to create an addon for concrete 5.7. Where there will be two views for adding texts. For this in main controller I have witten

$page1 = SinglePage::add('/dashboard/my_custom_texts', $pkg);
$page1->updateCollectionName(t('My custom List'));

$page2 = SinglePage::add('/dashboard/my_custom_texts/my_custom_textscat', $pkg);
$page2->updateCollectionName(t('My Category List'));

In concrete/packages/my_custom_texts/controllers/single_page/dashboard/my_custom_texts/my_custom_textscat.php

I have written

<?php        
namespace Concrete\Package\MyCustomTexts\Controller\SinglePage\Dashboard;
use \Concrete\Core\Page\Controller\DashboardPageController;
use Loader;
use \Concrete\Package\MyCustomTexts\Src\TextcatPageList;
defined('C5_EXECUTE') or die(_("Access Denied."));
class MyCustomTextscat extends DashboardPageController {
   public $helpers = array('form');
       public function view()
       {
           $ctextList = new TextcatPageList();       
           $ctextList->setItemsPerPage(25);
           $paginator = $ctextList->getPagination();
           $pagination = $paginator->renderDefaultView();
           $this->set('textslist',$paginator->getCurrentPageResults());

?>

But in view
concrete/packages/my_custom_texts/single_pages/dashboard/my_custom_texts/my_custom_textscat.php
when I am writting

<?php foreach ($textslist as $tl) : ?>
<?php     echo($tl->sID)?>
<?php endforeach;?>

It is showing error Invalid argument supplied for foreach().

Need help to fix this.

There is nothing glaringly obvious here, you will need to go through your package and put echo statements in key places to make sure that the right functions are called and return what you expect.

Hello hutman,
In concrete/packages/my_custom_texts/controllers/single_page/dashboard/my_custom_texts/my_custom_textscat.php I wrote

public function view()
 {
           echo "Show my custom texts";

even that is also not displaying.

Have you changed any of your file structure/paths since you installed the package? The correct paths/namespaces must be in there before installation or they won't work. Also, do you have all caches turned off and debugging turned on?
