    This framework is also for people who are tired of trying to hack a single “theme framework” to bits via a functions.php file just to make simple changes.

    Yes! This is exactly what I have been doing and hate it.

    Thank you so much!

    • Justin Tadlock

      This is something I’ve found that many people just hate doing. It can be a useful technique for minor things, but when you have a 10+ kb functions file, things just get crazy. At that point, it’s just easier to create the entire theme.

      Same here – I think it’s been a learning curve for everyone in a best practices approach for relational theming 🙂

      The first versions of several “frameworks” had me turning more things off in functions.php, bypassing templates and re-widgetizing, just to get what I needed.

      So far Hybrid Core is looking pretty interesting.

      Thank you!

      • Justin Tadlock

        Spending time working with one of those types of themes really gave me some perspective on the entire thing. I’m not sure if this would’ve ever been released without all of feedback I’ve gotten, especially in the last year, from people actually creating full themes and trying to mold a single theme into something it’s not. It wasn’t fun for me or them.

        I think this approach will definitely cater to people that have been turning things off and completely overwriting things.

  2. Luciano Passuello

    Wow, I checked the source code and this is really top-notch, as expected from every code that Justin ships. Thanks for making this widely available!

    Should we expect to see a Theme Hybrid release with the new 1.0 core soon?

    Cool, would mind saying a few words as to how this stands in relation to the normal hybrid framework? Successor? Can one migrate? etc.


    • Justin Tadlock

      I left this on the forums where you asked, but I’ll leave my reply here too.

      This *is* the normal Hybrid framework. For those of you that have been using the Hybrid parent theme at any point in the last two years, you’ve always been using Hybrid Core. Hybrid Core is the framework used in the Hybrid parent theme. So, it’s not a successor; it’s something you’ve already been using. There’s nothing to migrate to.

      Hybrid Core is just a separate, drop-in package for other theme authors to use when creating parent themes.

  4. Graeme Wilson

    Great work Justin! I’ve updated my article on converting websites to WordPress to mention the new Hybrid Core framework as well as Theme Hybrid. I’ll try and find some time over the coming week to put the Core through its paces.

    Awesome, I’ve already started playing with Hybrid Core via the SVN. I’ve also been working on my own premium themes for release. So I though this to be the best for building upon and already have one listed built of version 0.9 of the core. You can see them @ http://themelit.com.

    • Justin Tadlock

      Cool. Be sure to really look at what’s going on in version 1.0 compared to 0.9. The number of changes to make this thing a viable framework is ridiculous. In many ways, it’s not even the same framework. Big changes like this won’t happen often, but it’s definitely ready for real use now.

      Also, check out the Prototype theme, which is a great example of how Hybrid Core 1.0 can be used.

  8. Robert

    Yes! Thanks so much for this Justin. My major efforts with the Hybrid child theme were changing the widget output and often the breadcrumb code as well and then generally disabling a whole bunch of other stuff.

    Can’t wait to get a chance to use this shiny, new framework…

  9. ubcoltweb

    Thank you Justin! We’ve been using Hybrid since 0.5 here at UBC. Your work is truly amazing.

  10. Tiago Duarte

    Great job Justin!
    I’m having a small problem when installing the theme though: everytime i add it, i get some fopen erros about a style.css file… I searched for a solution and all i found was to edit PHP config to enable url fopen, yet that didn’t work…

    I thought it was some bug on the theme but everyone else seems to be okay.
    Any light on this problem would be very appreciated 🙂

    Keep up the good work.

      A direct quote from the blog post above should shed a little light on your issue:

      Hybrid Core is a development framework for creating WordPress parent themes. It is not a WordPress theme.

  11. Phlow

    What I love about your work: I learn a lot of tricks and some profound developement. You’re so meticulous and precise in your work, I just have to lif tmy head for that. Following your steps helps to save time and errors. Even if you have to think a lot at first. But you profit from the code in the future.

  15. Caspar

    Thanks a bunch, Justin! Hybrid Core is exactly what I’ve been working on for a couple of weeks now – only it is sooooo much better than anything I’ve been able to come up with so far!

    I as well as my pals came reviewing the great tips and tricks on your web site and unexpectedly I had an awful feeling I never thanked the website owner for those techniques. The women were totally thrilled to read them and now have sincerely been taking pleasure in these things. Thank you for simply being so helpful and also for making a decision on such helpful themes most people are really desperate to be aware of. My personal honest regret for not expressing gratitude to you earlier.


    One good reason to use this framework ?
    What are the pros and cons (limitations), since you have made this ?
