We’ve completed a bunch of stuff on this collection! We created a customized WordPress block that fetches knowledge from an exterior API and renders it on the entrance finish. Then we took that work and prolonged it so the information additionally renders straight within the WordPress block editor. After that, we created a settings UI for the block utilizing elements from the WordPress InspectorControls bundle.
There’s one final bit for us to cowl and that’s saving the settings choices. If we recall from the final article, we’re technically capable of “save” our choices within the block settings UI, however these aren’t truly saved wherever. If we make a couple of choices, save them, then return to the put up, the settings are fully reset.
Let’s shut the loop and save these settings in order that they persist the subsequent time we edit a put up that accommodates our customized block!

Saving settings attributes
We’re working with an API that gives us with soccer soccer staff rating and we’re utilizing it to fetch for displaying rankings based mostly on nation, league, and season. We will create new attributes for every of these like this:
// index.js
attributes: {
knowledge: {
sort: “object”,
},
settings: {
sort: “object”,
default: {
nation: {
sort: “string”,
},
league: {
sort: “string”,
},
season: {
sort: “string”,
},
},
},
},
Subsequent, we have to set the attributes from LeagueSettings.js. Each time a ComboboxControl is up to date in our settings UI, we have to set the attributes utilizing the setAttributes() methodology. This was extra straightfoward after we have been solely working with one knowledge endpoint. However now that we have now a number of inputs, it’s a bit extra concerned.
That is how I’m going to arrange it. I’m going to create a brand new object in LeagueSettings.js that follows the construction of the settings attributes and their values.
// LeagueSettings.js
let localSettings = {
nation: attributes.settings.nation,
league: attributes.settings.league,
season: attributes.settings.season,
};
I’m additionally going to vary the preliminary state variables from null to the respective settings variables.
// LeagueSettings.js
const [country, setCountry] = useState(attributes.settings.nation);
const [league, setLeague] = useState(attributes.settings.league);
const [season, setSeason] = useState(attributes.settings.season);
In every of the handle______Change(), I’m going to create a setLocalAttributes() that has an argument that clones and overwrites the earlier localSettings object with the brand new nation, league, and season values. That is finished utilizing the assistance of the unfold operator.
// LeagueSettings.js
operate handleCountryChange(worth) {
// Preliminary code
setLocalAttributes({ …localSettings, nation: worth });
// Remainder of the code
}
operate handleLeagueChange(worth) {
// Preliminary code
setLocalAttributes({ …localSettings, league: worth });
// Remainder of the code
}
operate handleSeasonChange(worth) {
// Preliminary code
setLocalAttributes({ …localSettings, season: worth });
// Remainder of the code
}
We will outline the setLocalAttributes() like this:
// LeagueSettings.js
operate setLocalAttributes(worth) {
let newSettings = Object.assign(localSettings, worth);
localSettings = { …newSettings };
setAttributes({ settings: localSettings });
}
So, we’re utilizing Object.assign() to merge the 2 objects. Then we are able to clone the newSettings object again to localSettings as a result of we additionally must account for every settings attribute when there a brand new choice is made and a change happens.
Lastly, we are able to use the setAttributes() as we do usually to set the ultimate object. You’ll be able to verify if the above attributes are altering by updating the choices within the UI.
One other technique to verify is to do a console.log() in DevTools to seek out the attributes.
Look nearer at that screenshot. The values are saved in attributes.settings. We’re capable of see it occur dwell as a result of React re-renders each time we make a change within the settings, due to the useState() hook.
Displaying the values within the blocks settings UI
It isn’t very helpful to retailer the setting values within the management choices themselves since each relies on the opposite setting worth (e.g. rankings by league relies on which season is chosen). However it is rather helpful in conditions the place the settings values are static and the place settings are unbiased of one another.
With out making the present settings sophisticated, we are able to create one other part contained in the settings panel that reveals the present attributes. You’ll be able to select your technique to show the settings values however I’m going to import a Tip element from the @wordpress/elements bundle:
// LeagueSettings.js
import { Tip } from “@wordpress/elements”;
Whereas I’m right here, I’m going to do a conditional test for the values earlier than displaying them contained in the Tip element:
<Tip>
{nation && league && season && (
<>
<h2>Present Settings: </h2>
<div className=”current-settings”>
<div className=”nation”>
Nation: {attributes.settings.nation}
</div>
<div className=”league”>
League: {attributes.settings.league}
</div>
<div className=”season”>
Season: {attributes.settings.season}
</div>
</div>
</>
)}
</Tip>
Right here’s how that winds up working within the block editor:
API knowledge is extra highly effective when dwell knowledge could be proven with out having to manually replace them each time. We are going to look into that within the subsequent installment of this collection.
