Add filter
Overview
In this guide you'll learn, how to create a filter for the Shopware administration. A filter is just a little helper for formatting text. In this example, we create a filter that converts text into uppercase and adds an underscore at the beginning and end.
Prerequisites
This guide requires you to already have a basic plugin running. If you don't know how to do this in the first place, have a look at our Plugin base guide.
Creating the filter
First we create a new file in the directory
<plugin root>/src/Resources/app/administration/src/app/filter. In this case we name our filter example, so our file will be named example.filter.js.Here's an example how your filter could look like:
<plugin root>/src/Resources/app/administration/src/app/filter/example.filter.js
1
const { Filter } = Shopware;
2
​
3
Filter.register('example', (value) => {
4
if (!value) {
5
return '';
6
}
7
​
8
return `_${value.toLocaleUpperCase()}_`;
9
});
Copied!
As you can see, it's very simple. We use
Filter from the Shopware object where we can register our filter with the method register. The first argument we pass is the name of our filter, which is example. The second argument is a function with which we format our text.If you want to use multiple arguments in your filter function, it could look like this:
1
Filter.register('example', (value, secondValue, thirdValue) => {
2
...
3
});
Copied!
Last, import the filter into your plugin's
main.js file.Next steps
Now that you know how to create a filter for the administration, we want to use it in our code. For this head over to our using filter guide.
