Laminas View is a powerful templating engine that allows you to separate your presentation logic from your application logic. In this topic, we'll explore the world of Laminas View and template rendering, and learn how to use it to build dynamic and maintainable views. **What is Laminas View?** Laminas View is a templating engine that allows you to define templates for your views. It's a simple and flexible way to separate your presentation logic from your application logic. With Laminas View, you can define templates for your views using a simple syntax, and then use these templates to render data in your views. **Setting up Laminas View** To use Laminas View, you'll need to install the Laminas View component and configure it in your application. You can do this by running the following command in your terminal: ```bash composer require laminas/view ``` Once you've installed the component, you'll need to configure it in your application's `module.config.php` file. Here's an example of how to configure Laminas View: ```php <?php return [ //... 'view_manager' => [ 'display_template_path' => __DIR__. '/../view', 'template_map' => [ 'layout/layout' => __DIR__. '/../view/layout/layout.phtml', 'index/index' => __DIR__. '/../view/index/index.phtml', ], ], ]; ``` In this example, we're telling Laminas View to look for templates in the `view` directory, and to use the `layout/layout.phtml` template for the `layout` view, and the `index/index.phtml` template for the `index` view. **Template Syntax** Laminas View uses a simple syntax to define templates. Here's an example of a simple template: ```php <p>Hello, <?php $name = $data['name']; echo $name;?>!</p> ``` In this example, we're using the `$name` variable to display the value of the `name` key in the `$data` array. **Template Inheritance** One of the power features of Laminas View is template inheritance. Template inheritance allows you to define a base template, and then inherit from it in your child templates. Here's an example of how to define a base template: ```php // view/layout/layout.phtml <!DOCTYPE html> <html> <head> <title><?= $title?></title> </head> <body> <?= $content?> </body> </html> ``` And here's an example of how to inherit from it: ```php // view/index/index.phtml // Inheritance <?= $this->getLayout()->getDefaultTemplate()->render('layout', [ 'title' => 'Home', 'content' => 'Hello, world!', ])?> ``` In this example, we're using the `getLayout()` method to get the current layout, and then using the `getDefaultTemplate()` method to get the default template. We're then passing an array of variables to the `render()` method, which will render the template and pass the variables to it. **Template Partials** Template partials are a way to reuse code in your templates. Here's an example of how to define a template partial: ```php // view/helpers/partial.phtml <h2><?= $title?></h2> <p><?= $description?></p> ``` And here's an example of how to use it: ```php // view/index/index.phtml // Using the partial <?= $this->partial('partial', [ 'title' => 'Home', 'description' => 'This is a partial', ])?> ``` In this example, we're using the `partial()` method to include the `partial.phtml` template and pass it an array of variables. **Conclusion** In this topic, we've covered the basics of building views with Laminas View and template rendering.

Topic: Building views with Laminas View and template rendering

Introduction

In the previous topics, we covered the basics of routing, controllers, and views in Laminas. Now, it's time to dive deeper into building views with Laminas View and template rendering. Laminas View is a powerful templating engine that allows you to separate your presentation logic from your application logic. In this topic, we'll explore the world of Laminas View and template rendering, and learn how to use it to build dynamic and maintainable views.

What is Laminas View?

Laminas View is a templating engine that allows you to define templates for your views. It's a simple and flexible way to separate your presentation logic from your application logic. With Laminas View, you can define templates for your views using a simple syntax, and then use these templates to render data in your views.

Setting up Laminas View

To use Laminas View, you'll need to install the Laminas View component and configure it in your application. You can do this by running the following command in your terminal:

composer require laminas/view

Once you've installed the component, you'll need to configure it in your application's module.config.php file. Here's an example of how to configure Laminas View:

&lt;?php
return [
    //...
    'view_manager' =&gt; [
        'display_template_path' =&gt; __DIR__. '/../view',
        'template_map' =&gt; [
            'layout/layout' =&gt; __DIR__. '/../view/layout/layout.phtml',
            'index/index' =&gt; __DIR__. '/../view/index/index.phtml',
        ],
    ],
];

In this example, we're telling Laminas View to look for templates in the view directory, and to use the layout/layout.phtml template for the layout view, and the index/index.phtml template for the index view.

Template Syntax

Laminas View uses a simple syntax to define templates. Here's an example of a simple template:

&lt;p&gt;Hello, &lt;?php $name = $data['name']; echo $name;?&gt;!&lt;/p&gt;

In this example, we're using the $name variable to display the value of the name key in the $data array.

Template Inheritance

One of the power features of Laminas View is template inheritance. Template inheritance allows you to define a base template, and then inherit from it in your child templates. Here's an example of how to define a base template:

// view/layout/layout.phtml
&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;&lt;?= $title?&gt;&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;?= $content?&gt;
&lt;/body&gt;
&lt;/html&gt;

And here's an example of how to inherit from it:

// view/index/index.phtml
// Inheritance
&lt;?= $this-&gt;getLayout()-&gt;getDefaultTemplate()-&gt;render('layout', [
    'title' =&gt; 'Home',
    'content' =&gt; 'Hello, world!',
])?&gt;

In this example, we're using the getLayout() method to get the current layout, and then using the getDefaultTemplate() method to get the default template. We're then passing an array of variables to the render() method, which will render the template and pass the variables to it.

Template Partials

Template partials are a way to reuse code in your templates. Here's an example of how to define a template partial:

// view/helpers/partial.phtml
&lt;h2&gt;&lt;?= $title?&gt;&lt;/h2&gt;
&lt;p&gt;&lt;?= $description?&gt;&lt;/p&gt;

And here's an example of how to use it:

// view/index/index.phtml
// Using the partial
&lt;?= $this-&gt;partial('partial', [
    'title' =&gt; 'Home',
    'description' =&gt; 'This is a partial',
])?&gt;

In this example, we're using the partial() method to include the partial.phtml template and pass it an array of variables.

Conclusion

In this topic, we've covered the basics of building views with Laminas View and template rendering. We've learned how to set up Laminas View, define templates, use template syntax, template inheritance, and template partials. With these skills, you'll be able to build dynamic and maintainable views for your Laminas application.

Practice Exercise

Create a new template view/index/index.phtml with the following code:

// Inheritance
&lt;?= $this-&gt;getLayout()-&gt;getDefaultTemplate()-&gt;render('layout', [
    'title' =&gt; 'Home',
    'content' =&gt; 'Hello, world!',
])?&gt;

And create a new template view/helpers/partial.phtml with the following code:

// Using the partial
&lt;h2&gt;&lt;?= $title?&gt;&lt;/h2&gt;
&lt;p&gt;&lt;?= $description?&gt;&lt;/p&gt;
