in v2.11.2 you now have a number of additional shortcodes to play with

see here: https://wordpress.org/plugins/wppizza/faq/ – > what are the available shortcodes

i have also added a bunch of classes and id’s to the article and header elements.
i.e an article has something like this “wppizza-article-special-offers-16”, where the last integer is the category id , whereas the bit before the id and after wppizza-article- bit is the category slug (so in this case “special-offers”). you’ll probably get the rest from here

one note though: as people might have customised their css using direct selectors somewhere, i cannot hardcode a wrapper div around this , however, there are a couple of filters you can use to add this like so (add the below to your themes functions.php:

/***************
	wrap loop in div
	with category id added to classname
************/
add_action('wppizza_loop_outside_start', 'le879_wrap_loop_start',10,4);
function le879_wrap_loop_start( $the_query, $options,  $termSlug, $categoryId) {
	if($the_query->found_posts>0){/*only add div if >0 posts*/
		print"<div class='some-prefix-".$categoryId."'>";/*or use the termslug or whatever*/
	}
}
add_action('wppizza_loop_outside_end', 'le879_wrap_loop_end',10,1);
function le879_wrap_loop_end($the_query) {
	if($the_query->found_posts>0){/*only add div if >0 posts*/
		print"</div>";
	}
}

i figure you can work it out from here, but if you have questions just shout

>Do you know why this is happening?

can’t even begin to guess without a link….

>OR a textfield in Ingredients Window

already part of that extension….(just select –add textbox- from the dropdown in custom groups)

although you could mess around with the arguments in the ‘wppizza_filter_loop’ filter, it won’t loop over that page to show you all the headers (i.e. category names) all it would/could do is to show *all* items on one page. so this will only partially be helpful.
(essentially you’d be changing the query , but that doesn’t affect the header)

easiest thing to do – and i wanted to do that for a while anyway but never got round to it – is for me to add the possibility of a shortcode that allows all categories to be displayed , so you dont have to think about it again. might take a couple of days though, depending on what else crops up.

while I’m at it, I might as well also add a class to the headers and articles that references the selected category – probably by id as the navigation has this already as id’s – which should help you in the second scenario when you need to show/hide things

although the navigation widget/shortcode was only meant to be used if you use templates, it should work in your scenario too…..(with a bit of creative js, showing/hiding things depending on class/id)

>1 how to print all menu items…

just put multiple shortcodes on the page

>2. how to use categories navigation without reloading the page?

you’ll need to write some script that does that

alternatively, put all the shortcodes on their own distinct pages and use/find a theme that loads all pages in one go and then just shows/hides whenever the appropriate link is clicked.
i know there are some / have seen some , but off the top off my head i don’t know which one

https://support.wp-pizza.com/paypal-gateway-extension/ ->troubleshooting

that Captain Hour plugin decided that it’s a good idea to change the server/php timezone settings dynamically (and does not reset them when it’s done with whatever it is it’s doing)

i cannot even begin to tell you how bad an idea this is…..

that’s something they have to fix. got nothing to do with me

>Why would he not get a few and I am getting a copy of them all?

very good point. you will have to speak to whoever deals with your emails and see what delivery reports/logs say etc…
maybe some got junked for some reason ?

really nothing i can do my end I would have thought…..

>Thanks for looking into this.

no problem, was kind of fun
