delete_row($selector, $row, [$post_id])
$selector(string) (Required) The field name or field key.

$post_id(mixed) (Optional) The post ID where the value is saved. Defaults to the current post.

- Added in version 5.3.2
Delete via field name
This example shows how to delete a row of data from a field called ‘images’ on the current post being viewed.
// Delete the first row of data. delete_row('images', 1);
Delete via field key
This example shows how to achieve the same as above using the field’s key instead of its name.
// Delete the first row of data. delete_row('field_123456', 1);
When targeting a specific row number, please note that row numbers begin from 1 and not 0. This means that the first row has an index of 1, the second row has an index of 2, and so on. To begin indexes from 0, please use the row_index_offset setting like so.
Usage inside loops
When you use
delete_row(), it will update the database and reindex the array of repeater or flexible field items. Therefore, you should not use this function inside a
have_rows loop to avoid inconsistent data.
