Hi there
I did a search and read the update_field documentation but i’m a little confused.
I basically just want to be able to update a post’s repeater data from my template files.
So i have a post (ID 512) which has a repeater called ‘users’ which has ‘name’, ‘surname’, telephone’ text fields.
I looked in the DB and these are stored as documented so:
udetails_1_name – ‘dave’
_udetails_1_name – ‘field_532b122e8afe1’
udetails_2_name – ‘mark’
_udetails_2_name – ‘field_532b122e8afe1’
etc…
My question is how do i use the update_field function to say change dave’s name to ‘paul’ or remove mark all together (along with his second name and telephone).
I am confused as to how the function:
update_field($field_key, $value, $post_id)
How the field key in this case is the same for both ‘rows’ so if i did:
update_field(‘field_532b122e8afe1’, ‘whatever’, 512)
this does not target any of the repeater’s data rows specifically.
Also how would you go about deleting a row from the front end or adding one in? I could do it manually i guess with SQL but maintaining the correct sequence of:
udetails_1_name
udetails_2_name
udetails_3_name
etc will be tricky and i’d rather use your inbuilt functions…. just totally stuck as to how to go about it.
thanks
After a bit more reading i think where i am confused is that maybe that you use update_field each time to add in all rows at once?
So you’d have a multidemensional array off ‘all’ of the rows which then bulk overrides?
If so does that mean you use the field_key of the actual repeater?
e.g.
udetails – 2
_udetails – field_532b0f308afe0
update_field(‘field_532b0f308afe0′, $multi-demensional-array, 512)
If this is correct what would the array be structured like in my case?
$multi-demensional-array = array(
[0] -> array('field_532b122e8afe1' => 'paul', ''field_532b123c8afe2' => 'brown')
[1] -> array('field_532b122e8afe1' => 'mark', ''field_532b123c8afe2' => 'smith')
)
EDIT:
right so i tried this on another post
$udata = array(array('field_532b122e8afe1' => 'paul', 'field_532b123c8afe2' => 'brown'));
update_field('field_532b0f308afe0', $udata, 654);
added in perfectly so think i have answered my own question :D. I guess the technique to just amend one row would be to build up the above array with the change and all of the previous data. Seems a bit counter-intuitive but i guess writing an add/delete row function is a pain in the a$$ as you’d have to deal with maintaining the sequential meta keys as opposed to just re-creating them as i assume the update_field function does.
