Frequently, you may find yourself in Shopware 6 where you need to change the active switch of a custom field on checking another custom field’s switch. Such a situation occurs very often when you want to avoid conflicting configurations or to ensure that mutually exclusive options are selected. This article is a guide on how to achieve this using JavaScript overrides in Shopware 6.
Problem
It’s a matter of changing the value of one custom field depending on the status of another. More precisely, change on a custom API checkbox (`custom_api_checkbox_two`) when another checkbox (`custom_api_checkbox_one`) is checked, and vice versa.
Solution
We will add this functionality in JavaScript overrides at Shopware. JavaScript overrides allow us to extend or modify code functionality without directly changing the core files.
Take a look at an example code snippet demonstrating how to get this:
javascript
Shopware.Component.override('sw-inherit-wrapper', {
methods: {
setupCheckboxEventListeners() {
const checkboxOne = document.querySelector('[name="custom_api_checkbox_one"]');
const checkboxTwo = document.querySelector('[name="custom_api_checkbox_two"]');
if (checkboxOne) {
checkboxOne.addEventListener('change', this.handleCheckboxTwo);
}
if (checkboxTwo) {
checkboxTwo.addEventListener('change', this.handleCheckboxOne);
}
},
handleCheckboxTwo(event) {
const checkboxTwo = document.querySelector('[name="custom_api_checkbox_two"]');
if (event.target.checked) {
if (checkboxTwo && checkboxTwo.checked) {
checkboxTwo.checked = false;
const event = new Event('change');
checkboxTwo.dispatchEvent(event);
}
}
},
handleCheckboxOne(event) {
const checkboxOne = document.querySelector('[name="custom_api_checkbox_one"]');
if (event.target.checked) {
if (checkboxOne && checkboxOne.checked) {
checkboxOne.checked = false;
const event = new Event('change');
checkboxOne.dispatchEvent(event);
}
}
}
},
mounted() {
this.setupCheckboxEventListeners();
}
});
```
How It Works
1. Extend `sw-inherit-wrapper`
Extend the behaviour of the component `sw-inherit-wrapper`, which is used very often to manage inheritable settings.
2. Create Event Listeners
We create the event listeners in `setupCheckboxEventListeners` method to detect changes in both of our custom checkboxes.
3. Handle checkbox Change
`handleCheckboxOne` and `handleCheckboxTwo` handle the changes of the checkboxes. At one switch, it de-selects the other switch and triggers a change event to keep consistency.
Implementation Steps
Step 1. Copy the provided JavaScript code snippet.
Step 2. Navigate to your Shopware 6 project’s custom theme or plugin where you have access to JavaScript overrides.
Step 3. Paste the code into an appropriate JavaScript file (e.g., `src/Resources/app/administration/src/overrides/customFieldOverrides.js`).
Step 4. Ensure the file is included and loaded properly in your Shopware 6 administration area.
Step 5. Clear the cache if necessary and reload the administration area to apply the changes.
Conclusion
Following these steps and implementing the provided code is going to make sure that your custom API checkboxes work accordingly and uncheck one when the other is checked. This will make the user experience better and avoid unnecessary configuration conflicts inside your Shopware 6 environment. If you encounter any other problems or require help in other areas, simply hire a Shopware developer to handle these tasks more easily.
