How to show registration error within popup window?

[matheso]

Hello, I've created a custom sign-up form which pops up on the index page (it can be accessed directly via taskbasket.net/gallery/registration.html

but when a user doesn't fill the form correctly (no password given, or taken username, etc), the popup window redirects to the original register.php and shows an error. I've attached 3 screenshots. Screenshot #1 shows the pop-up registration form, #2 shows the error I'm talking about and #3 shows how I want the error to be displayed.

I'd like it shown in real-time, within the pop-up window. Can you help? I'm struggling.

Thank you

Sorry. I did not read the topic with attention and I gived a wrong answer. I must edit.
I do not know the answer.

I suggest to check for potential errors in your custom form before you submit the values to register.php.

[matheso]

Cool, I'll give it a shot. Except I don't understand how I'll include portions of register.PHP into my custom registration.html file.

I know how to include entire php files, but not only sections. I'm assuming I need to add the following php to my custom html file, but we'll see what happens!

Wait, it seems more logical to change my html to a php. Will report back

[matheso]

It doesn't seem to work with the php I posted above.

I changed my custom registration page from html to php and included the php code shown above. I wrote the code within proper php tags, right below this html form code:

Code Select Expand

<input type="submit" name="submit" class="action-button" value="Submit" />

But upon submit, it doesn't show the error in real-time within the form (instead it reverts me to register.php to see the error).

Thoughts?

You don't need to copy code from register.php. If you want to show potential issues in real time, you need to add some JavaScript code that performs checks even before anything is submitted anywhere. Have a look at js/register.js to get an idea what should be checked.

[matheso]

I was able to solve this problem, you can take a look here:  http://taskbasket.net/gallery/      and click "Sign-up" in the top-right corner. It checks for bad email/password before allowing you to click next. Any feedback on the design is welcome (positive or negative).
