Add hint about tags to posting form

[sterndata]

People use hashtags, perids, semicolons, etc. Add a hint to the tag field.

like this but formatted nicely.

+1. Here's my patch and it actually works.

3218: add help text for topic tags using aria-describedby attribute

[audrasjb]

Oh, I didn't seen @Mirucon patch before uploading mine :)

So I think the difference between the two patches:
– mine is using aria-describedby attribute for a better accessibility of this help text
– Mirucon's is using <p> tag and CSS which is great

How about mixing these two approaches? :)

About aria-describedby,see: ​https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_aria-describedby_attribute

Sounds good, but let's only do it for the WordPress.org/support theme:

• wordpress.org/public_html/wp-content/themes/pub/wporg-support

Let's not do it on the bb-base, bbPress, or BuddyPress themes, also the wporg-forums theme is no longer used so no point updating this theme either, all i18n sites should be using the new theme I now believe.

Hi @netweb,

So wordpress.org/public_html/wp-content/themes/pub/wporg-support/bbpress/form-reply.php is the correct place, right? Should we add it on wporg-support/bbpress/form-topic.php as well?

I'll be making a new patch and it will merge the approach from @audrasjb's patch.

[audrasjb]

Ok, great @netweb !

@Mirucon feel free to ask any help if needed :)

Merged approach from @audrasjb

In 6050:

Support Theme: Add "Separate tags with commas" hint to "Topic Tags" input.

Props Mirucon, audrasjb, sterndata.
Fixes #3218.
