Voyons ensemble aujourd’hui comment ajouter un block de contenu dans une page magento via les observers.
\nPour l’exemple on va se baser sur la probl\u00e9matique suivante :
\nJe souhaite afficher un message particulier sur la page du panier pour les clients qui ne sont pas connect\u00e9s.
\nLe contenu du message doit \u00eatre g\u00e9rable dans le backoffice via un block cms.<\/p>\n
En analysant la structure du fichier de layout checkout.xml pour la page panier, on constate qu’il existe un noeud de type core\/text_list dans lequel nous allons inserer le contenu.<\/p>\n
<checkout_cart_index>\r\n...\r\n<block type=\"core\/text_list\" name=\"additional.product.info\" translate=\"label\">\r\n<label>Additional Product Info<\/label>\r\n<\/block>\r\n<\/checkout_cart_index>\r\n<\/pre>\nPour r\u00e9aliser cela nous allons cr\u00e9er un module. ( je ne d\u00e9taille pas la proc\u00e9dure ) qui va se baser sur l\u2019\u00e9v\u00e9nement : controller_action_layout_generate_blocks_after
\n<\/strong>via le code suivant dans le fichier config.xml<\/p>\n \r\n<events>\r\n\u00a0<controller_action_layout_generate_blocks_after>\r\n\u00a0 <observers>\r\n\u00a0\u00a0 <test_add_block_layout_xml>\r\n\u00a0\u00a0\u00a0 <class>Hhennes_Tests_Model_Observer<\/class>\r\n\u00a0\u00a0\u00a0 <method>testAddBlockToLayoutXml<\/method>\r\n\u00a0\u00a0 <\/test_add_block_layout_xml>\r\n\u00a0 <\/observers>\r\n\u00a0<\/controller_action_layout_generate_blocks_after>\r\n<\/events>\r\n<\/pre>\nPuis voici le code de l’observer :<\/p>\n
<?php \r\nclass Hhennes_Tests_Model_Observer\u00a0 {\r\n\u00a0 \r\n\u00a0 \/**\r\n\u00a0\u00a0 * Ajout d'un contenu dynamique dans le layout\r\n\u00a0\u00a0 *\/\r\n\u00a0 public function testAddBlockToLayoutXml($observer) {\r\n\u00a0 \u00a0\r\n\u00a0\u00a0\u00a0 $action = $observer->getAction();\r\n\u00a0\u00a0\u00a0 $layout = $observer->getLayout();\r\n\u00a0\u00a0 \u00a0\r\n\u00a0\u00a0\u00a0 \/\/Sur la page du panier : On ajoute le texte d'un block cms\r\n\u00a0\u00a0\u00a0 if ( $action->getRequest()->getOriginalPathInfo() == '\/checkout\/cart\/') {\r\n\r\n\u00a0\u00a0\u00a0\u00a0\u00a0 $additionnalBlock = $layout->getBlock('additional.product.info'); \/\/R\u00e9cup\u00e9ration du block parent auquel on veut ajouter le contenu\r\n\u00a0\u00a0\u00a0\u00a0\u00a0 $cmsBlock = $layout->createBlock('cms\/block','test_block')->setBlockId('dresses-skirts'); \/\/Cr\u00e9ation du block cms dans le layout\r\n\u00a0\u00a0\u00a0\u00a0\u00a0 $additionnalBlock->append($cmsBlock,'test_add_cms_block'); \/\/Ajout du nouveau block au block parent\r\n\u00a0\u00a0\u00a0\u00a0 \u00a0\r\n\u00a0\u00a0\u00a0 }\r\n\u00a0\u00a0 \u00a0\r\n\u00a0 }\r\n\u00a0 \r\n}<\/pre>\nAvec ce principe il est ainsi possible d’ajouter facilement du contenu sur n’importe laquelle de vos pages, de mani\u00e8re programmable.<\/p>\n","protected":false},"excerpt":{"rendered":"
