Load Multiple Class

 

I'm actually following the tutorial of Pierre Fay but i'm working on a page in the admin side but i don't get the correct way to put a second class "Mymodule\Admin_Page\Block\Contactlists" idea someone ?

<?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>Module Mymoodule</title>
        </head>
        <body>
            <referenceContainer name="content">
                <block class="Magento\Backend\Block\Template" template="Mymodule_AdminPage::nettoyage.phtml"/>
            </referenceContainer>
        </body>

Re: Load Multiple Class

check namespace and xml block name

 

namespace Mymodule\Admin_Page\Block\Adminhtml;

in xml you write

Mymodule\AdminPage\Block\Adminhtml\Contactslist

 Clear difference Admin_Page and AdminPage

<?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">

        <referenceContainer name="content">
            <block class="Mymodule\Admin_Page\Block\Contactlists" template="Mymodule_AdminPage::nettoyage.phtml"/>
        </referenceContainer>
    </body>
</page>

Now create your block class,

You can extend base class like this,

<?php
namespace Mymodule\AdminPage\Block\Adminhtml;

class Contactlists extends \Magento\Backend\Block\Template
{
  public function mycustom(){
      //your code
      return;
  }
}

Remove var/generation folder.

class Contactslist extends \Magento\Backend\Block\Template
{
    public function test()
    {
        echo 'helloworld';
    }
}

and my layout

<?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>Module Mymodule</title>
        </head>
        <body>
            <referenceContainer name="content">
                <block class="Mymodule\AdminPage\Block\Adminhtml\Contactslist" template="Mymodule_AdminPage::nettoyage.phtml"/>
            </referenceContainer>
        </body>

Re: Load Multiple Class

@Antoine553 which is your line no. 12,

You can set class definataion in your block file like this,

 

<?php
namespace Mymodule\AdminPage\Block\Adminhtml;

use Magento\Backend\Block\Template;

class Contactslist extends Template
{
    public function test()
    {
        echo 'helloworld';
    }
}
