Automated ID’s on headings causes duplicate ID, breaks validation

    Hey!

    Testing WordPress 5.9 RC 3

    While the automatic id attributes on headings might be practical, it does cause an issue when validating documents with multiple identical headings. Like this:

    Vegetables (h1)
    Carrot (h2)
    Nutrition (h3)
    Potato (h2)
    Nutrition (h3)

    In this case, both “Nutrition” headings will automatically be assigned the same id #Nutrition, which breaks validation and isn’t best practice.

    Has anyone got an idea on how to disable that feature in WordPress 5.9?

    In this case, both “Nutrition” headings will automatically be assigned the same id #Nutrition, which breaks validation and isn’t best practice.

    I just tried 5.9-RC3, and my experience was different: a dash and a number were always added to subsequent IDs when the texts were the same.

    So in your specific example, the IDs would be nutrition, nutrition-1, nutrition-2, etc.

    Great feedback @gappiah – thank you 😊

    I see that heading ids are suffixed with -n when typed manually.

    But try and duplicate a heading or a group containing headings. Does the suffixing kick in? Not on my test site.

    Testing this on WP 5.9 RC 4 now, will report back findings shortly…

    I can confirm that on WordPress 5.9 RC4 that copied blocks do not properly generate -n heading IDs and instead provide the same heading ID as its copied block.

    Sample Post content (the second Potato/Nutrition set of blocks were copied from the first set): https://cloudup.com/ckViRHnh43w

    Will now test with the latest version of Gutenberg to see if I can replicate there as well.

    This appears to be the related Gutenberg issue: https://github.com/WordPress/gutenberg/issues/36365

    I can confirm that this still exists with Gutenberg 12.4.1 activated as well.

    Marking this topic as resolved, as there is a related ticket for follow-up, and further discussions about it should happen there so it is not lost.
