Hi,

According to this help guide and an existing setting in the AdminCP

https://invisioncommunity.com/4guides/themes-and-customizations/advanced-theming/managing-theme-settings-r128/

<?php

return \IPS\Settings::i()->bot_antispam_type === 'recaptcha2';

This would return true for use in a conditional theme setting so that a setting will be shown or not, but when I try this using my own custom theme setting:

<?php

return \IPS\Theme::i()->my_theme_setting == true;

it gives me an error:

Error: Undefined constant "my_theme_setting" (0)
#0 C:\laragon\htdocs\ips4-dev-theme3\system\Theme\Theme.php(1818): eval()
#1 C:\laragon\htdocs\ips4-dev-theme3\system\Theme\Theme.php(1797): IPS\_Theme->getCustomSettingField(Array)

#8 C:\laragon\htdocs\ips4-dev-theme3\admin\index.php(13): IPS\_Dispatcher->run()
#9 {main}

I've also tried:

<?php

return theme.my_theme_setting == true;

This attempt produces no errors, but the theme setting doesn't show, it is hidden:

return $this->my_theme_setting == true;

and this one gives me undefined constant again!

return $this->theme.my_theme_setting == true;

Er, little help please?!

You would want to use

\IPS\Theme::i()->settings['my_theme_setting']

 

Thanks Stuart, just found the same in one of my old topics!

Hmm, I'm wondering why this doesn't return true if this setting is enabled?

<?php 
return \IPS\Theme::i()->settings['my_theme_setting_enabled_or_not'] == TRUE;

It relates to a custom theme setting (a toggle) that is enabled and directly precedes this one that I'm entering the conditional logic into?

clarification

<?php 
return \IPS\Theme::i()->settings['my_theme_setting_enabled_or_not'];

Do not attribute the value.

Thanks, Adriano! Still not working though. The toggle setting is still hidden.

If you want to see its content, you should use print or echo instead of return. Return will work on a method/function.

Thanks, I was sort of following the example of the recapcha image color in custom tab.

I tried dumping it and comes back as NULL

Hi,

Do we know if this functionality is designed to work 'as is' in Custom Theme Settings?

Presumably, the setting is eval'd when the settings page loads or is updated via some AJAX or something so that it knows what to display.

It kind of seems back to front to me. Setting A should toggle Setting B on/off but the way it is set up says the code goes in Setting B (so it toggles itself on/off based on Setting A).

The text description below the Condition field suggests it should work, so it is probably a case of me not using the correct theme setting format, because although there is no error generated, all it seems to actually do is hide itself from view after saving. I can't see it working as the setting shows as NULL unless that's what it checks for. Maybe I should check for not null! 

 

 

 

 

There are 2 errors there and I told you yesterday.

Thanks, I just took a screenshot while trying out different variations.

I did try your corrected syntax but for some reason, it didn't work.

 

Update: It returns NULL for other custom theme settings too. It works for a standard one like primary_button so I must have the syntax wrong for the variable. If it wasn't asking for raw PHP, I could just use theme.mysetting

Further testing!

You mean this...

 

 

How much is it worth? mwahahahahaaaa

 

But seriously...this is the conditional for the second of the 2 settings in that video:

<?php
return (boolean) $this->settings['neapp_theme_setting_1'];

 

Edited December 12, 20231 yr by Nathan Explosion

LOL!

 

Think I need to get the value and not the key!

I'm close, I used array_values and custom theme settings are not in that array!

print_r(array_values(\IPS\Theme::i()->settings));
exit;

 

Edited December 12, 20231 yr by The Old Man

Mate...why are you still trying that? Look at what I posted...

LOL Thanks! Didn't see your updated post.

Doesn't work for me though!

I can however now see all my custom theme settings though:

<?php

print_r(array_values($this->settings));
exit;

OK, as you can see in my video it's working fine for me.

Attaching another video of the full thing being done.

Thanks mate, yes that's exactly what I have but it doesn't work for me, even though it has too!

Okay, I tried re-entering theme dev mode and now it works when saving and reloading the page. Weird.

 

I thought so...

In that video, you appear to be expecting the toggling of the field to be 'live' - but it doesn't work like that.

Change the first field, scroll down, click Save and reload, check the second field.

That's what I am doing in the videos.

Edited December 12, 20231 yr by Nathan Explosion

Thanks, TBH I thought I reloaded it but must have missed that. I did expect it to show when toggled on (live). It is working now, thank you so much for confirming the right syntax. I wrote a plugin once, and I'm sure it worked live when toggling.

2 minutes ago, The Old Man said:

Oh, that works in plugins/applications where you have complete control over the code of the fields.

You don't have that with themes as fast as I can see.

Aha, thanks for that. It would be nice if it updated via Ajax or something. Thought I was going insane so I just watched my first video again, and I did save and reload at the very end but it didn't make the setting visible.  Perhaps some kind of caching issue. Yes, I'll claim that!
