I have a repeater that has a read-only field that has a shortcode with an unique id. I need this ID, so I can have shortcodes that can output the other values in the repeater row.
This is the (summarized) way I add fields:
acf_add_local_field_group(
'key' => 'pricing_group',
'title' => 'Pricing',
'fields' => [
'key' => 'pricing_user_monthly_fees',
'label' => 'User Monthly Fees',
'name' => 'user_monthly_fees',
'type' => 'repeater',
'instructions' => 'Please create different fee ranges depending on the amount of users the customer wants to sign-up for.',
'layout' => 'table',
'button_label' => 'Add Range',
'sub_fields' => [
[
'key' => 'pricing_user_monthly_fees_minimum',
'label' => 'Minimum',
'name' => 'minimum',
'type' => 'number',
'instructions' => 'Please enter a minimum value for this range.',
'wrapper' => [ 'width' => '20' ],
'min' => 0,
'parent_repeater' => 'pricing_user_monthly_fees',
],
[
'key' => 'pricing_user_monthly_fees_maximum',
'label' => 'Maximum',
'name' => 'maximum',
'type' => 'number',
'instructions' => 'Please enter a maximum value for this range.',
'wrapper' => [ 'width' => '20' ],
'min' => 0,
'parent_repeater' => 'pricing_user_monthly_fees',
],
[
'key' => 'pricing_user_monthly_fees_fee',
'label' => 'Fee',
'name' => 'fee',
'type' => 'number',
'instructions' => 'Please enter a fee for this range.',
'wrapper' => [ 'width' => '20' ],
'parent_repeater' => 'pricing_user_monthly_fees',
],
[
'key' => 'pricing_user_shortcode',
'label' => 'Shortcode',
'name' => 'shortcode',
'type' => 'text',
'readonly' => 1,
'instructions' => 'When you save this range, a shortcode is generated as a read-only field. You can use this shortcode to display the range\'s fee.',
'wrapper' => [ 'width' => '40' ],
'parent_repeater' => 'pricing_user_monthly_fees',
],
],
],
'location' => [
[
[
'param' => 'options_page',
'operator' => '==',
'value' => 'acf-options-pricing',
],
],
],
);
This is the function that generates a shortcode with an unique id:
public function store_unique_shortcode(string $post_id)
{
$screen = get_current_screen();
if ($post_id !== 'options'
&& !isset($screen->id)
&& !strpos($screen->id, 'acf-options-pricing')) { return; }
$field = get_field('pricing_user_monthly_fees', $post_id);
if (!$field) { return; }
$user_monthly_fees = array_map(function($user_monthly_fee) {
return array_merge($user_monthly_fee, [
'shortcode' => $user_monthly_fee['shortcode'] ?:
sprintf('[pricing_user_monthly_fee id="%s"]', uniqid()),
]);
}, $field);
update_field('pricing_user_monthly_fees', $user_monthly_fees, $post_id);
}
The problem is that when I use get_field() it shows an empty shortcode value while I expect it to contain the shortcode string with a unique id.
If I dump $field I get the following:
array(1) {
[0]=>
array(4) {
["minimum"]=>
string(1) "0"
["maximum"]=>
string(1) "3"
["fee"]=>
string(4) "18.5"
["shortcode"]=>
string(0) ""
}
}
If I dump $user_monthly_fees I get the array with the shortcode and the generated unique id.
array(1) {
[0]=>
array(4) {
["minimum"]=>
string(1) "0"
["maximum"]=>
string(1) "3"
["fee"]=>
string(4) "18.5"
["shortcode"]=>
string(50) "[pricing_user_monthly_fee id="646c94d8b29f2"]"
}
}
If I dump right after update_field() I get an array with an empty shortcode value.
array(1) {
[0]=>
array(4) {
["minimum"]=>
string(1) "0"
["maximum"]=>
string(1) "3"
["fee"]=>
string(4) "18.5"
["shortcode"]=>
string(0) ""
}
}
Why doesn’t get_field() return the shortcode with the generated unique id?
