Gebruik de ACF plugin om volledige controle te krijgen over je WordPress bewerk schermen, aangepaste veldgegevens en meer. **Voeg velden toe op aanvraag.** De ACF veldbouwer stelt je in staat om snel en eenvoudig velden toe te voegen aan WP bewerkschermen met slechts een paar klikken! Of het nu iets eenvoudigs is zoals het toevoegen van een “auteur” veld aan een boekbeoordeling bericht, of iets complexers zoals de gestructureerde data behoeften van een e-commerce site of marktplaats, ACF maakt het toevoegen van velden aan je inhoud model gemakkelijk. **Voeg ze overal toe.** Velden kunnen overal in WordPress worden toegevoegd, inclusief berichten, pagina’s, gebruikers, taxonomie termen, media, reacties en zelfs aangepaste opties pagina’s! Het kon niet eenvoudiger zijn om structuur te brengen in de WordPress inhoud creatie ervaring. **Toon ze overal.** Laad en toon je aangepaste veldwaarden in elk thema template bestand met onze probleemloze, ontwikkelaarsvriendelijke functies! Of je nu een enkele waarde moet tonen of inhoud moet genereren op basis van een complexere query, de kant-en-klare functies van ACF maken templating een droom voor ontwikkelaars van alle ervaringsniveaus. **Elke inhoud, snel.** WordPress omtoveren tot een echt content managementsysteem gaat niet alleen om extra velden. Het maken van nieuwe extra berichttypes en taxonomieën is een essentieel onderdeel van het bouwen van aangepaste WordPress sites. Het registreren van berichttypes en taxonomieën is nu mogelijk direct in de ACF UI, waardoor de workflow voor inhoud modellering wordt versneld zonder dat je code hoeft aan te raken of een andere plugin hoeft te gebruiken. **Simpelweg prachtig en bewust toegankelijk.** Voor de makers van de inhoud en degene die data invoeren is de veld gebruiksvriendelijkheid zo intuïtief als ze kunnen wensen en past het naadloos in de WordPress ervaring. Toegankelijkheid standaarden worden regelmatig herzien en toegepast om te garanderen dat ACF zo goed als iedereen kan ondersteunen. **Documentatie en ontwikkelaar handleidingen.** Meer dan 10 jaar aan levendige bijdrage van de community in combinatie met een doorlopende toewijding om de documentatie schoon te houden zorgen ervoor dat je de hulp kan vinden die je nodig hebt om te bouwen wat je wilt. #### Functies * Simpel & intuïtief * Krachtige functies * Meer dan 30 veldtypen * Uitgebreide documentatie * Miljoenen gebruikers #### Links * [Site](https://www.advancedcustomfields.com/?utm_source=wordpress.org&utm_medium=free%20plugin%20listing&utm_campaign=ACF%20Website) * [Documentatie](https://www.advancedcustomfields.com/resources/?utm_source=wordpress.org&utm_medium=free%20plugin%20listing&utm_campaign=ACF%20Website) * [Ondersteuning](https://support.advancedcustomfields.com) * [ACF PRO](https://www.advancedcustomfields.com/pro/?utm_source=wordpress.org&utm_medium=free%20plugin%20listing&utm_campaign=ACF%20Pro%20Upgrade) #### PRO De Advanced Custom Fields plugin is ook beschikbaar in een professionele versie met meer velden, meer functionaliteit en meer flexibiliteit.

Adding and managing fields feels simple and clear. It gives good control without making things messy. Very solid plugin for regular use. ![](https://secure.gravatar.com/avatar/3e51047ca445ee2ab6172fd4c2b15b8bd0696005499717baf5d5c968f3c9f61e? s=60&d=retro&r=g) ### 󠀁[Must Have Tool](https://wordpress.org/support/topic/must-have-tool-24/)󠁿 [tyriqsuth](https://profiles.wordpress.org/tyriqsuth/) 27 maart 2026 One of the best plugins I’ve used.

Works smoothly and is very flexible. tnx to devs, really helped in my projects 👍 ![](https://secure.gravatar.com/avatar/d7d33d6796b2344b6cad6169c496a3a456b59e9d6e5187f573d3c12f5a9105ee? s=60&d=retro&r=g) ### 󠀁[Flexible Fields Tool](https://wordpress.org/support/topic/flexible-fields-tool/)󠁿 [albertowadsworth](https://profiles.wordpress.org/albertowadsworth/) 5 maart 2026 ACF really helps when adding custom fields to posts n pages. Setup is pretty simple and very flexible. Took a little time to learn at first, but works great once you get used to it.

However, this plugin requires either the paid version or custom PHP theme to display the content on the front end! There are no blocks included and the support on the website seems to be referring to the old editor.This is the kind of walled garden approach I don’t think should be welcome from WordPress plugins.I have wasted a huge amount of my time trying to make this plugin work, have now given up and am using a directory plugin instead. I would have preferred ACF as it’s a simpler solution but even being savvy and using ChatGPT I couldn’t get my fields to show up in the free WordPress theme. ![](https://secure.gravatar.com/avatar/4c46a8b91b0bd43df5a8fe1586eae5c2d41368c977e53aea41e535a79931f82a? s=60&d=retro&r=g) ### 󠀁[Flexible & Reliable](https://wordpress.org/support/topic/flexible-reliable/)󠁿 [kellymann](https://profiles.wordpress.org/kellymann/) 2 maart 2026 ACF really helps me build custom layouts without extra hassle. Field setup is clear& options are flexible. Saves a lot of dev time. There’s a bit of a learning curve at first, but once you get it, it works really well. ![](https://secure.gravatar.com/avatar/926b53d9cd410694e12a9ae92da4cb73cca0f751bcc645f9259e19ecf63db0f0? s=60&d=retro&r=g) ### 󠀁[Very Flexible Tool](https://wordpress.org/support/topic/very-flexible-tool/)󠁿 [sheapurcell64](https://profiles.wordpress.org/sheapurcell64/) 19 februari 2026 Using Advanced Custom Fields really helped me control custom data easily. UI is clean and setup is simple. Saved a lot of dev time. Cz of that my workflow feels smoother.
