How to Override Custom Module PHTML by Another Custom Module – Magento 2

layoutmagento2overridesphtml

I've a malfunctioning module that needs to be overwritten in some parts. I would like to create a custom module that fixes that module instead of making changes in a theme as suggested in magento docs. The problem is that I'd rather keep my fixing module next to bad one so I can easily reuse it in another projects.

Another way is to remove malfunctioning phtml by layout.xml in a custom (fixing) module and replace that file with one of my own.

Which way is better and should be performed in cases like mine?

Simplest way to override phtml template using Custom module. just add sequence into module.xml and then override your layout with template.

That set.

And if you want to override it using theme then just copy layout xml file & set your template path to that file with block and append in it.

It is also possible in UI component with the <switcherConfig>. You can refer magento sales rule module form UI component file. I had a same requirement and I did it by using following code.

<field name="allow_to_proceed" sortOrder="10" formElement="checkbox">
<argument name="data" xsi:type="array">
    <item name="config" xsi:type="array">
        <item name="source" xsi:type="string">page</item>
        <item name="default" xsi:type="number">0</item>
    </item>
</argument>
<settings>
    <dataType>boolean</dataType>
    <label translate="true">Allow Proceed to Checkout</label>
    <dataScope>allow_to_proceed</dataScope>
    <switcherConfig>
        <rules>
            <rule name="0">
                <value>1</value>
                <actions>
                    <action name="0">
                        <target>custom_module_rules_form.custom_module_rules_form.actions.skip_other_rules</target>
                        <callback>show</callback>
                    </action>
                    <action name="1">
                        <target>custom_module_rules_form.custom_module_rules_form.actions.remove_discount</target>
                        <callback>show</callback>
                    </action>
                </actions>
            </rule>
            <rule name="1">
                <value>0</value>
                <actions>
                    <action name="0">
                        <target>custom_module_rules_form.custom_module_rules_form.actions.skip_other_rules</target>
                        <callback>hide</callback>
                    </action>
                    <action name="1">
                        <target>custom_module_rules_form.custom_module_rules_form.actions.remove_discount</target>
                        <callback>hide</callback>
                    </action>
                </actions>
            </rule>
        </rules>
        <enabled>true</enabled>
    </switcherConfig>        
</settings>
<formElements>
    <checkbox>
        <settings>
            <valueMap>
                <map name="false" xsi:type="number">0</map>
                <map name="true" xsi:type="number">1</map>
            </valueMap>
            <prefer>toggle</prefer>
        </settings>
    </checkbox>
</formElements>

Here <target> is your form_datacomponent_name.section_name.field_name .

Magento 2 – Define Constants or Variables Once and Reuse in Custom Module

There are different ways like:

a) helper class

1) Declare the helper class and define your constants and variables in it.

2) Inject it as a dependency in all your classes.

3) Now the constants and variables will be available in all your classes.

b) Config.xml

1) Declare your constants and variables in it.

2) You can access its values using ScopeConfigInterface.

3) If you don't know how, leave your comment and I will update my answer.

c) Class with constants and static varibles

1) Declare a Class with constants and static varibles

2) Now you can access the constants and variables without instantiating the class.

Choose as per your requirement.
