I’ve been searching for hours for a solution to what I feel is a common issue with rows of a repeater field.
Basically I have a repeater field that holds links users can create. The rows have several fields (url, image, display name, etc). I have created a form on the front-end to add/update/delete these links which all works fine (not using the acf_form).
What I am looking for is a way for the users to update the row order (index) on the front-end like you can do on the back end by dragging and dropping. I don’t need the headache of trying to recreate the drag & drop functionality I just need a way to update the row index. I understand I can get the row index using get_row_index but how do you update that number? This is essential because these links are used to create user pages and I have to give users a method to change the order of how they appear on their page without the use of the drag and drop functionality of acf_form.
Am I overthinking thinking this? Should I instead just add another field (ie. display order) to the row and use that for my sort? It seems like there has to be a way to do this using built-in functions. I can’t be the only person that has to custom sort repeater rows right? 🙂
The only way to change to order of the rows from a coding standpoint is to get the entire repeater as an array, reorganize the array and then re-save the entire repeater. the index of a row is only the order of that row in the array.
$repeater = array(
array(
// row array
'field_1' => 'value',
'field_2' => 'value'
),
array(
// row array
'field_1' => 'value',
'field_2' => 'value'
)
)
Hey John, thanks for the reply!
What I’ve done instead is added a unique ID to each row using code from a previous post I found. Now I only need one more thing…
The unique ID is only saved to the row after the first “save” of the row data. Since I am adding/updating/editing the rows using update_sub_field function the “save” never fires. Is there a way to recreate pushing the update button of the acf_form. I don’t need it to update any data, I just need it to fire the creation of the unique ID.
Ps. Are you the only active person on this forum? It seems like I see your name everywhere! 🙂
As far as I know, there isn’t a way to fire the save. ACF is fired to save when a post is saved or a term and there is something custom in options pages, but I think it still happens on a WP hook.
What you’ll need to do is check do a check of the existing rows when a row is updated and create the ID for rows where it is missing.
PS: There are other people that answer questions. I’m as active as I am because, well, I am paid help, or give what help I can. I can’t answer every question because some of them are beyond my knowledge. This is a user forum and depends on users. In the end I am really just another user, I have been using ACF for so long that I can’t remember building a site without it and I also like helping others if I can. Other people like me have come and gone, it’s not an easy job and can be frustrating at times.
