How to Change Block Arguments in Magento 2

In this post, I’m going to guide you on how to change block arguments in Magento 2.

How to Change Block Arguments

First, you need to modify the targeted block arguments you are going to change.

For the block arguments to be modified, the <referenceBlock> instruction is used.

Below is an example of how to change the existing block argument’s value and also add a new argument.

  • Initial block declaration:
<block class="Namespace_Module_Block_Type" name="block.example">
    <argument name="label" xsi:type="string">Block Label</argument>
  • Extending layout:
<referenceBlock name="block.example">
    <!-- Modified block argument -->
    <argument name="label" xsi:type="string">New Block Label</argument>
    <!- Newly added block argument -->
    <argument name="custom_label" xsi:type="string">Custom Block Label</argument>


That’s all. I have just provided you an instruction on how to modify block arguments in Magento 2 using the <referenceBlock> instruction. I hope it is helpful for you. If you have any questions or new ideas, feel free to leave a comment below.
