[resolved] [Plugin: AutoNav Graphical Navigation and Gallery Plugin] Some syntax fixes for W3C validation (5 posts)

    Hi..

    First off... ABSOLUTELY AWESOME plug-in... I cannot express how much you have made me happy, because I've been wanting a plug-in that does just this (picture navigation for sub-pages) for sometime... and this one is absolutely perfect

    This is what my sites current sub-page menu looks like:
    http://f1stockcars.com/the-drivers/profiles/ (at time of writing this post)

    It's very poor isn't it, and something that has been annoying me for sometime

    But I am currently giving my site a makeover, and while waiting for Justin Tadlock to release his updated 'get-the-image' plug-in for WP2.9, i noticed your post in his comments about "Autonav"

    This is what my sub-page menu will look like when my site make-over launches:
    http://test.f1stockcars.com/the-drivers/profiles/

    GLORIOUS - exactly what I wanted - THANK YOU SO MUCH

    OK, now the gushing is over, here's why I'm posting:

    I noticed I was getting a weird styling error in every browser except Firefox, and couldn't trace why (using trusty FireBug)... so I ran the page through W3C validator to see if it threw up anything

    It showed me there was a stray 'end paragraph' tag in the generated code of each table cell

    Now i know nothing about PHP or Javascript, but i somehow managed to find the cause in the code and remove it...

    In turn i then decided to see if i could figure out a couple of other syntax errors being highlighted by W3C

    These included no close tag for the images, no alt tag for the images, and no close tag for the last tr of the table

    Somehow, and i'm still not quite sure how i did it, but i managed to figure all these errors out and get the page to pass validation, so i figured i'd post the code for you, to save you some work

    Once again, many thanks for your work, it's much appreciated

    defade,

    Many thanks! It is still strange to have to write <br /> ... a decade and a half habit of writing HTML and they change the rules? Sigh.

    I am working on an update with your suggested patches plus I did discover another case or two where incorrect nestings could be output. Watch this space.
