Resolved Select field with DB table lookup

Hi,

I asked this question in the past, but I have to clear something up.
I have a select field in my EP that looks for values in a DB table.
The table contains roughly 20,000 rows.
Problem is that this multiple select field loads the whole table, needless to say it slows things down when editing profile.
My question: is there a way to not preload the table?

Thanks.

I'm sorry but as we said is a very complex thing, this requires a lot of JavaScript and PHP knowledge.

You need:
- write PHP code to retrieve options from DB in JSON format
- call jQuery UI framework from Joomla API, docs at https://docs.joomla.org/J3.x:Javascript_Frameworks
- include Jquery Autocomple Javascript library (I don't know if already included in UI Joomla framework)
- load javascript code with your customization

Our tip is only point of start.

Hi,
Sorry this is not possible. Select field is provided directly by Joomla API.

Select field is a simple HTML select input, all features like search and UI are provided by JQuery choosen javascript library (built-in Joomla), so you have 2 problems that make delays:
- Download webpage with 20000 occurrences
- Browser need to parse all options via javascript

I figured that much.
Is there any workaround? Can I introduce a search box in EP that would look for a table values and act as if it was a multiple input field?
Many thanks.

Is there any workaround?
Yes but is complex, you can use a simple text field and add some javascript code to make the autocomplete with options taken from ajax requests.

Some docs tip:
