Accessing Data in Templates

When a $data array is passed into a view file or a template, all properties of the $data array are accessible within those contexts. For example, if the $data array contains a 'name' property of 'John' and an 'age' property of 21, these details can be rendered as follows:

<?php echo $name.' '.$age; ?>

Additionally, to inspect all properties within the $data array, you can use var_dump($data), print_r($data), or Trongate's json() function within the view file or template. For example:

<?= json($data) ?>

In Summary

• Templates provide the overall structure for web pages.
• View files contain specific content that is injected into a web page.
• Trongate's template() method should be used to load templates.
• Information can be passed into templates and views in the form of an array.
• If content from view files is to be injected into a template, a 'view_file' property should be initialized as part of a $data array.
• The value of the 'view_file' property should be equal to the file name of the target view file, but without the .php suffix. For example:

$data['view_file'] = 'homepage_content';

• When injecting a 'view_file' property into a template, it is good practice to also initialize a 'view_module' property. This gives the framework clear instructions as to the location of the target view file. For example:

$data['view_module'] = 'welcome';
$data['view_file'] = 'homepage_content';

• If the first segment of the URL matches the module name calling the template, the 'view_module' declaration can be omitted.
• Within template files, the following PHP code should be added to signify where view file content should appear:

<?= Template::display($data) ?>

• Trongate's json() function can be used from within a template or a view file to confirm what properties have been passed in. For example:

<?= json($data) ?>
