There’s a semicolon missing near the end. There’s no syntax checker here and I just type code straight into the message most of the time assuming that people can correct minor syntax errors when needed.
add_filter('acf/validate_value/name=end_date', 'validate_end_date_func', 10, 4);
function validate_end_date_func($valid, $value, $field, $input) {
if (!$valid) {
return $valid;
}
$repeater_key = 'field_56faad2a333ab';
$start_key = 'field_56fab49fd51ce';
$end_key = 'field_56fab4d1d51d0';
// extract row from input
$row = preg_replace('/^\s*acf\[[^\]]+\]\[([^\]]+)\].*$/', '\1', $input);
$start_value = $_POST['acf'][$repeater_key][$row][$start_key];
$end_value = $value;
if ($end_value <= $start_value) {
$valid = 'end value must be greater than start value';
}
return $valid;
}
