Hi Max. I'm using chronoforms 6 and i'm facing a problem with repeater area.
I Just created a repeater area with inputs and I already managed to set it up and save te values in json format.
What is the best way to load json and populate the repeater inputs from read_data in order to edit saved data?

Hi Bob. below the solution.

In the “found event” of “read_data” put a php to decode json saved before looping repeater area input.
The json format looks like: “[{"installment":"1000"},{"installment":"200"},{"installment":"300"}]”
Below is the php code use to decode and loop:

$installments_array = array();

$jsondec = json_decode($this->get("read_data7.Product.installments"), true);

$i = 0;
foreach ($jsondec as $json) {
  $a = $json['installment'];
  $installments_array["installments[".$i."][installment]"] = $a;
  $i++;
}

$this->data("installments_array", $installments_array, true);

once the array is filled, put “{data:installments_array}” in the data provider of repeater area and “{var:area_repeater_name.row}” in the data provider of the text field and that’s it.
The repeater will instantiate as many text field as the array elements number filed up with respective values
