Magento – How to pass arguments to phtml block

blockslayoutmagento2xml

I've updated the default breadcrumbs.phtml which now displays the company logo within the breadcrumb section, however I do not need the logo to show on category pages.

I have tried to update my catalog_category_view.xml to pass an argument to the block:

<?xml version="1.0"?>
<!--

 * See COPYING.txt for license details.
 */
-->
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <block class="Magento\Theme\Block\Html\Breadcrumbs" name="breadcrumbs" as="breadcrumbs"/>
            <arguments>
                <argument name="show_logo" xsi:type="boolean">false</argument>
            </arguments>
        </block>
    </body>
</page>

and within my breadcrumbs.phtml I am trying to get the value of the show_logo by:

echo $this->getData('show_logo');

Unfortunately, this isn't working?

Can anyone please help me to understand why this isn't working and how I can get this to work so that I can check the argument so I can check whether to show the logo or not?

Thanks

Best Answer

You have to use the following method instead of:

$this->getShowLogo();

If you want to know the value, use vardump() or print_r().Hope it help you!

Magento 2 – How to Rewrite TierPrice Block

Suppose package:Learning and module: Custom

Module.xml looks like

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Module/etc/module.xsd">
    <module name="Learning_Custom" setup_version="2.0.0">
        <sequence>
            <module name="Magento_Catalog"/>
        </sequence>
    </module>
</config>

And then create a layout xml following path -> app/code/Learning/Custom/view/frontend/layout/catalog_product_prices.xml

<layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/layout_generic.xsd">
    <referenceBlock name="render.product.prices">
        <arguments>
            <argument name="default" xsi:type="array">
                <item name="prices" xsi:type="array">
                    <item name="tier_price" xsi:type="array">
                        <item name="render_template" xsi:type="string">Learning_Custom::product/price/tier_prices.phtml
                    </item>
                </item>
            </argument>
        </arguments>
    </referenceBlock>
</layout>

Create template inside your module or copy base template file inside your module path should be -> app/code/Learning/Custom/view/frontend/templates/product/price/tier_prices.phtml

Magento 2 – How to Set and Get Block Arguments Programmatically

If you look further in the code, in the \Magento\Framework\View\Layout\Generator\Block class, the createBlock function only adds data from the $arguements['data'] element. So, I think you should change your code to this:

$block = $this->frameworkViewLayout
    ->createBlock(
        "Company\Module\Block\Hello",
        "block_name",
        [
            'data' => [
                'my_arg' => 'testvalue'
            ]
        ]
    )
    ->setData('area', 'frontend')
    ->setTemplate($template)
    ->toHtml();

Then you could use getMyArg() or getData('my_arg').
