Add realtime site address validation #10255

merged 9 commits into from Jul 22, 2019

commented Jul 19, 2019

Closes #9720.

This adds realtime validation for the site address in Login or Add Site. This is based on the iOS implementation described in wordpress-mobile/WordPress-iOS#10294 (comment).

  • The error is only shown if the user has not typed anything after 2 seconds
  • The Next button is only enabled if the URL is valid

To implement this, I moved all the site address logic to a new class, LoginSiteAddressValidator. The class encapsulates the validation, cleaning, and error reporting using debounce. A corresponding unit test, LoginSiteAddressValidatorTest, has also been added.

Known Issues

The LoginSiteAddressFragment doesn't retain any error message shown below the text field after configuration changes. I didn't attempt to fix this. I thought it would be a huge change.


Adding a Site

  1. Click on Sites → Switch Site.
  2. Click on the + button at the top right.
  3. Enter a site address.

Logging in with a self-hosted site

  1. On Login page, click on Login.
  2. Click on Log in by entering your site address.
  3. Enter a self-hosted site address.

On both scenarios, please test against the specs described above. Please also test that there are no regressions in logging in with a valid site.


Only 1 reviewer is needed but anyone can review.


We're hoping to get a review for the error message that is shown when the URL is invalid:

Enter a valid URL eg.

Move LoginSiteAddress validation to a class
This time, the _Next_ button is not enabled until the user has entered an invalid site address.
Site Address: Show an error message after 2 sec
The invalid address error message will only be shown 2 seconds after the user stopped typing.
Replace login_invalid_site_url
This is to match the new iOS error message.

For the error message, I'd go with something that explains the error a bit more fully and avoids abbreviations (like e.g.). For example:

Please enter a complete website address, like

This doesn't strike me as significantly longer than the current version, but let me know if it creates a length issue.

Update login_invalid_site_url
This is based on Editorial’s advice.

I like how it looks, @shiki.

I'm sorry I didn't catch this when reviewing this the first time, but I just saw that the first sentence on that screen could also use a small tweak -- the your/you sounds redundant (and it's strongly assumed that you'd only ever connect your own site). I'd go with this instead:

Enter the address of the WordPress site you'd like to connect.
