Adding outside store to wordpress theme

I’ve tried using this link for support but, being a WP Noob, it just goes over my head. I’m officially lost.

This is the code I need to add to my site.

<script type="text/javascript" src="https://www.redbubble.com/assets/external_portfolio.js"></script>
<script id="rb-xzfcxvzx" type="text/javascript">new RBExternalPortfolio('www.redbubble.com', 'sespider', 3, 3).renderIframe();</script>

Can anyone help me, please?
It may need to be noted that I’m using the OneTone theme and would like to add the code to a section of the theme and not a blog.
Thanks

I think you need to modify index.php of Onetone theme.

Before that, could you specify which section you want to add the store items?
There are Section1 to 6 in Onetone Options page of admin panel.
And is it before the section content or after?

It is recommended to make child theme, and duplicate index.php to the child theme and edit it.

I’ve added more sections to my theme then the default. Which you can see here:

I plan to add a Tab Panel to the Stores section and place the RB code in one of those tabs. But until then, I’ll like to add the code below my store links. Not a difficult thing to do, I’m sure. I just need to get it to work.

On a Side Note: I’m trying to add a outside WordPress link to the main nav bar. That doesn’t seem to be possible. Nor is it possible to add another page.

I haven’t a clue how to add a “Child Theme” or a Sub Domain via WordPress. I’ll have to look that up.

In that case, it is better using shortcode. Add the following code to functions.php of the theme.

function my_rb_js_handler($atts, $content=null) {
$str=<<<eot
<script type="text/javascript" src="https://www.redbubble.com/assets/external_portfolio.js"></script>
<script id="rb-xzfcxvzx" type="text/javascript">new RBExternalPortfolio('www.redbubble.com', 'sespider', 3, 3).renderIframe();</script>
eot;
	return $str;
}
add_shortcode('rb', 'my_rb_js_handler');

You can put [rb] anywhere in section and that’s it.

Why I recommend child theme is that above shortcode in functions.php will be deleted after theme update.
Child theme setup is not that difficult, so read the codex and just put above code in functions.php of the child theme.

About main nav bar:
You can add menu items only after sections links. In menu settings page, select your menu and check theme location as Home Page Header Menu.

Thank you so much for your help.
Now I have a better idea of how to make custom shortcodes. And your solution worked.

I’ll look into the child theme solution soon.

Sadly, the Menu section does not list any menus Including the one from the theme. I’ve not touched this section in fear of messing something up.

Little back story about me.
I’m coming from 4 years of not working on websites. When I did, it was normal html with very little css. Back when Flash was the go to feature for sites. And I wrote everything by hand. With the new html5, etc, I get lost easily. Please be patient with me.

No problem at all!

You don’t need to worry about theme related menus. They are handled by header.php of the theme according to the section settings.

Just fill in “Menu Name” and click “Create Menu”.
Now you can add menu items and there should be checkbox on bottom of right column.
Check “Home Page Header Menu” there and save menu.

Thank You, Again, Evan.

Something seems to be off.
I created a menu called “OutsideLinks”
I then clicked on the “Links” tab, created a link to my youtube channel (to replace Videos if works), and added it to the menu. Then saved of course.
Put clicking the button on my site only brings up a lightbox. How do I get it to open the link in a new tab/window instead of a lightbox?
It only seems to do this with YouTube. But it still only opens in the same window.

Once again, I can’t thank you enough for your help.

I think your link url should be following.
https://www.youtube.com/watch?v=fSoSipSFPGA&list=PLn9N9jhgkJ3L6Ud_4FSZcb-xSoExmiUIe&index=1
or
https://www.youtube.com/playlist?list=PLn9N9jhgkJ3L6Ud_4FSZcb-xSoExmiUIe

To open link in a new tab/window:
On right top in menu settings page, there should be “Display Option” button or somekind ( I don’t know english label cos I use Japanese ).
Click that and panel expands. Check “Link target” ( I guess.. ).
Now there is a checkbox in your YOUTUBE menu item section.

BTW, nice drawings!

Activated the “Open link in a new window/tab” and it’s working but, once again, not with YouTube.
YouTube just does not seem to like my theme. lol

And thanks for the complement

That’s odd..
Did you changed the url?
In my test environment, both urls works fine, and opened in new tab.

I’ll change it again so you can see it. Hang on a sec….

–EDIT–
Here’s a screen capture

I need it to open to the channel, not the playlist.
But neither is working. Page is live, if you’ll like to see what it’s doing.

It seems some javascript changes the url of youtube.
In HTML source, it’s https://www.youtube.com/sespider, but rendered url is https://www.youtube.com/embed/sespider.

YouTube Channel plugin looks suspicious to me. Pls try disable this plugin or change some settings of it.

I had installed a number of YouTube plugins and widgets, in hopes of getting one to work with the theme. YouTube Channel plugin was the only one that came close (with minor format issues). While deactivating them, I’ve found the code to one of the other plugins to work.

I’m thinking it might be a lightbox issue because after deactivationg all of the YouTube plugins, the lightbox still tried to open the link. It ended up doing what it’s currently doing.

I want to thank you again for your help. I’ve learned so much today. It’s almost 3am here so I’m going to call it a night and remove the youtube link after you reply back.
I’ve already reactivated the working YouTube plugin. It’ll have to work for now.
As a thank you, is there anything art related I may be able to help you with? For free of course.

Great News!
I wasn’t able to sleep until I found what was causing the issue.
It turned out to be the HUGE IT Lightbox plugin. For some odd reason, it kept wanting to embed any and all YouTube links.

I’ll wait until you reply before I mark this topic as solved.
Once again, Thank You and let me know if there’s anything I can help you with anything art related (logo, banner, etc).

Congratulation! Happy to hear that.

I do this for my study and training on WordPress and English, so never mind.
It is fun communicating with someone abroad.
Thanks for your proposal, though.
( I think it might violate the forum rule if I get any reward. It’s just voluntary thing. )
