[PP-2] Use form element of type date instead textfield when selecting a date in an exposed filter

I've changed the status to "Needs work" because this must be in the core. There is this contrib module https://www.drupal.org/project/date_popup → that could help.

I tested the patch #270 ✨ [PP-2] Use form element of type date instead textfield when selecting a date in an exposed filter Needs work and I get that in my view (it has two date fields in exposed filters)

So it works, but I don't need the time field in my case. So probably some other work on it is needed.

I applied #270 to an exposed filter on a timestamp field. I get this warning once I apply the filter:

Warning: Undefined array key "value" in Drupal\views\Plugin\views\filter\NumericFilter->acceptExposedInput() (line 426 of /home/shadysamir/work/almanassa/almanassa/web/core/modules/views/src/Plugin/views/filter/NumericFilter.php).

followed by

Warning: Undefined array key "value" in Drupal\views\Plugin\views\filter\Date->acceptExposedInput() (line 161 of /home/shadysamir/work/almanassa/almanassa/web/core/modules/views/src/Plugin/views/filter/Date.php).

both are trying to read this->value['value'] when the array is:

date: "2023-05-01"
time: "00:00:00"
type: "date"

The filter is not applied (not added to the SQL statement)

Drupal 9.5.3

Just a short heads-up, why this core issue is now even more important:
When trying to use date_popup or date_filter as workaround, but you're also using smart_date, it won't work! They're in conflict.

See ✨ Integrate with date_popup Fixed . So if anyone is using these contrib modules as workaround, take care.

With this core issue fixed, that will be solved.

Once this issue is fixed it will unblock also:
#3210945-28: Remove dependency on jquery_ui_datepicker →

Patch #270 no longer applies to 10.1.x

Berdir → changed the visibility of the branch 9.4.x to hidden.

Berdir → changed the visibility of the branch 2648950-pp-2-use-form to hidden.

Created a new merge requested from #270 and resolved conflict with 10.3. This is still postponed.

Here's the patch from that MR for those that wish to use it in their composer.json file
