Solved: Re: Controller can not find the template file

reikokurose240 · ‎07-11-2020

Hi I started larning Magento 2.3

I am developping an extension "Knc_Tips"

now menu is working, controller is fine maybe.

but, view file does not work. browser does not says any error but controller can not reach the view file I put.

etc/adminhtml/routes.xml

   <router id="admin">                                                                                                                                                                
        <route frontName="topic" id="topic">
            <module name="Knc_Tips"/>
        </route>
    </router>

Controller/Adminhtml/Posts/Index.php

public function execute()
{
    $resultPage = $this->pageFactory->create();
    $resultPage->getConfig()->getTitle()->prepend((__('Posts')));
    return $resultPage;
}

view/adminhtml/layout/topic_posts_index.xml

<?xml version="1.0"?>                                                                                                                                                                  
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <head<
        <title>
            Posts
        </title>
    </head>
    <body>
        <div>test</div>
        <referenceContainer name="content">
            <block class="Magento\Backend\Block\Template" template="Knc_Tips::posts.phtml" />
        </referenceContainer>
    </body>
</page>

I put some html contents on topic_posts_index.xml but nothing come out on browser.

although there is resource container "posts.phtml", this also does not come up.

when I access this page, there is a page title "Posts" only. I think this is from Controller.

I thought Controller does not read the template file, so I changed the template file name to

view/adminhtml/layout/test.xml

i did cache clean, but still display does not change. not 404. just says page title "Posts".

I believe "Controller does not reach the layout file"

where do i have to check and pay attension to solve this problem?

Hi @reikokurose240

So you have error in your layout (XML) file code, first is you have added <Head> tag wrong - check the syntax it is added like this - <head<

So it will not work here, put the following content in your view/adminhtml/layout/topic_posts_index.xml file

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <referenceBlock name="page.title">
        <action method="setPageTitle">
            <argument name="title" xsi:type="string">Posts</argument>
        </action>
    </referenceBlock>
    <body>
        <referenceContainer name="content">
            <block class="Magento\Backend\Block\Template" template="Knc_Tips::posts.phtml"/>
        </referenceContainer>
    </body>
</page>

Second, you need to create the template file as well, (PHTML File) wherein you can put your content which will load the template.

Create posts.phtml file in this location - view/adminhtml/templates/posts.html - Adding following content it it :

<p>My First Posts load from template</p>

Now run all the necessary commands again like setup:upgrade, compile and static content deploy then clear and flush cache and check!

It will work for you.
