I did some testing and I was unsuccessful at setting min/max on the repeater field based on another field. The min/max gets set but it seems that setting these after the field is loaded has no effect on the field. I have not had time to look at it further.
This is my code for this so far
add_action('acf/admin_head', 'test_add_script');
function test_add_script() {
?>
<script type="text/javascript">
(function($){
if (typeof(acf) == 'undefined') {
return;
}
acf.addAction('ready', function(e){
// on ready get number field
// key of number field
$('[data-key="field_607c5c906fe34"] .acf-input input').each(function(index, element) {
var value = $(element).val();
adjust_repeater(value);
});
});
// on change of number field get new value
// key of number field
$(document).on('change', '[data-key="field_607c5c906fe34"] .acf-input input', function(e) {
var field = acf.getField('field_607c5c906fe34');
var value = field.val();
adjust_repeater(value);
});
function adjust_repeater(value) {
// get the repeater field and set min max
// key of repeater field
var field = acf.getField('field_607c5cb56fe35');
field.data.min = value;
field.data.max = value;
}
})(jQuery);
</script>
<?php
}
Getting the row numbers would be problematic. Row numbers are generated differently depending on if they exist when a page is loaded or they are added. Already existing rows are like “row-0”, “row-1”, etc while new row values are generated using a uniqid function and look more like “6080311efeabf”. It is easier to get the count of rows by finding all all of a subfield in the rows, excluding the clone row that acf used to add additional rows.
// field keys for repeater and sub field
$(document).find('[data-key="field_XXXXXXX"] [data-key="field_YYYYYYY"]').not('[data-key="field_XXXXXXX"] .acf-clone [data-key="field_YYYYYYY"]').each(function(index, element) {
// then you can work on each row by getting the .acf-row each sub field is in
var row = $(element).closest('.acf-row');
}
Hopefully this helps you. Although I don’t know how doing this in the admin using JS is going to help you with a data import.
