QUESTION
I'm using react - redux environment for my web app and I'm not able to make an inifinite scroll, Once i reach the bottom, I'm getting an error that useEffect cannot be used. Here is the code below:
...ANSWER
Answered 2021-May-24 at 03:22You cannot call useEffect inside of another function because this breaks the rules of hooks. But the useEffect isn't doing anything here. You could just call fetchHomePosts(skipper+10) from morePosts().
That would load the second page. If you want to load the third and the fourth and so on then you need to make skipper a state rather than a var. Add 10 to skipper whenever you load a page.
You can either:
- Increment
skipperand callfetchHomePosts()in yourmorePosts()function. - Increment
skipperin yourmorePosts()function and callfetchHomePosts()from auseEffecthook which hasskipperas a dependency so that the effect runs whenever the value ofskipperchanges. - Save the last fetched page number in your Redux store.
- Base the offset on the length of the
homePostsarray.
You don't need to use useDispatch and connect. They are two ways of doing the same thing so you should use one or the other. The hooks are the recommended approach.
This is not perfect but I don't want to overcomplicate things:
QUESTION
I just launched my store on wordpress and I ran into a problem: When I am on the home page of the site, all my product titles are in H2 and should be in h3 (SEO reasons), my recommendation products are also in h2 instead of h3 (on the single product page and in collections, i would like to change them all to h3). I looked for a long time where the problem could come from, searched all the files of the theme to change any title from h2 to h3 but nothing helped, I can't find where it is! I also asked the theme creators for help but they told me it was woocomerce's fault and there was nothing they could do ..
A lot of people have had some of the same problem under other themes but they don't have the same "function.php" as me. I also followed this: How can I change the product
in Woocommerce Storefront to ? but it didn't work for me.Can someone help me on this problem ?
here is my "function.php" but i dont think it'll help..
...ANSWER
Answered 2021-May-19 at 21:08I don't think the functions.php file has anything to do with it - usually HTML structures like this are created in template php files which are in the themes folder - either on the top level of that folder or as "template parts" in an according subfolder. You have to edit those( or actually those among them that are used by the pages you are referring to), changing all
However, since any not-selfmade theme will be updated every now and then, those changes would be overwritten with updated files when available, it would be necessary to create a child theme, which only contains those templates which you want to change (see also https://developer.wordpress.org/themes/advanced-topics/child-themes/). Then again, updated themes might contain template updates which are necessary, so you'd always have to check which details were updated in that particular template file, integrating it into your child theme templates or editing the updated original themes and using them in your child theme.
P.S.: I think the title of your question is a bit misleading: In the question text you are asking about certain title tags in the product pages, not about parts of the menu, aren't you?

I am working on a task in which I have to implement infinite scroll paging of 600 dummy records to cards I have coded on FlatList render. So far I have implemented logic using FlatList but not successfully. Help is required where I am doing wrong thus not giving result. Here is the component code:

Answered 2021-Apr-19 at 19:08The thing here is that you are seting your dummy data and calling the apiCall next, the dummy data is not updated yet when you call the apiCall, ande the dummy data is shown as an empty array on the apiCall, you just ned to force some await before calling the function, just change from this:

I am working on a pure JavaScript infinite scroll. I have a 4 list of posts.
I am trying to load more posts (clones of the "original" ones) when I reach the bottom of the container.
...ANSWER
Answered 2021-Apr-12 at 13:52The array postsArary is initialized in the constructor and never updated: getLastPost() always returns the fourth post instead of the last one that was added dynamically. Consequently, the IntersectionObserver callback is only triggered by the fourth post and not by the one on the bottom of the page.
The updated getLastPost() method:

trying to load youtube comments into a infinite load component (using a npm for it)
the mess happens due to the fact the infinite load component is child of parent Accordion component (from react-bootstrap), and what I'm trying to achieve is fetching with useSWR only if Accordion gets clicked (opened).
What I tried is to use useSWR conditional, so that only fetches when state "show" is true, which is being set inside function:

I'm using nextjs Link with shallow and replace properties to change url from /author to /author?book=234523452 when the query is detected page conditionally hides an InfiniteScroll component and show a component with a single book instead.
Single book component has a "X" to go back (also wrapped within a Link) so to show again the InfiniteScrollComponent.
