Create a new template

Let's assume there is a list of menu pages from the Pages model: 

• About us
• Gallery
• Contacts

The main page is the 'About us' page and it is displayed using the view-index.php template. Thus, the 'Gallery' and 'Contacts' pages are displayed using the view-default.php template.

Now we decide to display a list of images from another model on the 'Gallery' page. To do this, we need to remove the gallery from the fallback template and create a separate template for this page, where we will display the gallery.

1. We set the link field for the Gallery page to 'gallery', now our page is available on request /gallery.

2. In the config/routes.php file, add a new line and thereby redirect the /gallery request to a new template.

   $mvFrontendRoutes = [
   
       '/' => 'view-index.php',
       'e404' => 'view-404.php',
       'fallback' => 'view-default.php',
       
       '/gallery' => 'view-gallery.php'
   ];

3. In the views folder, create a view-gallery.php file with the following content (the first 2 lines are needed if you want to highlight the menu page that the Pages model issues and issue a 404 error if the page does not exist or is disabled).

   <?
   //File views/view-gallery.php
   
   $content = $mv -> pages -> defineCurrentPage($mv -> router);
   $mv -> display404($content);
   include $mv -> views_path.'main-header.php';
   ?>
       <div class="main">
           <h1><? echo $content -> name; ?></h1>
           <div class="gallery">
   
           </div>
       </div>
   <?
   include $mv -> views_path.'main-footer.php';
   ?>

4. Now, on request /gallery, the view-gallery.php template file is included, in which we can add the gallery itself from another model. Let's take the simplest version of a gallery on MV, which is one field of a simple model.

   //File models/gallery.model.php
   
   class Gallery extends ModelSimple
   {
       protected $name = 'Gallery';
       
       protected $model_elements = [
           ['Gallery images', 'multi_images', 'photos']
       ];
   }

5. Create a models/gallery.model.php file, run the migration and get the gallery table in the database. Add a new model to the config/models.php file and get the administered Gallery module in the admin panel.

6. The gallery object is available as $mv -> gallery is an instance of a simple model with a single field photos. Extract photos, create thumbnails and wrap everything in html tags.

   //File views/view-gallery.php
   
   <div class="gallery">
   <?
       $photos = $mv -> gallery -> photos;
       $photos = $mv -> gallery -> extractImages($photos);
   
       foreach($photos as $photo)
       {
           echo '<a href="'.$mv -> root_path.$photo['image'].'">';
           echo $mv -> gallery -> cropImage($photo['image'], 200, 200).'</a>';
       }
   ?>
   </div>

7. Final view of the file views/view-gallery.php

   <?
   $content = $mv -> pages -> defineCurrentPage($mv -> router);
   $mv -> display404($content);
   include $mv -> views_path.'main-header.php';
   ?>
       <div class="main">
           <h1><? echo $content -> name; ?></h1>
           <div class="gallery">
           <?
               $photos = $mv -> gallery -> photos;
               $photos = $mv -> gallery -> extractImages($photos);
   
               foreach($photos as $photo)
               {
                   echo '<a href="'.$mv -> root_path.$photo['image'].'">';
                   echo $mv -> gallery -> cropImage($photo['image'], 200, 200).'</a>';
               }
           ?>
           </div>
       </div>
   <?
   include $mv -> views_path.'main-footer.php';
   ?>
