PODIO php API调用，使用按应用程序ID过滤来获取所有项目字段值的数组偏移量

Question

I'm new in API thing, I'm using PHP CLient of PODIO link here , I want to get all fields value of all items.

The code below is not working, but if I used PodioItem::get_basic(item_id) , this work to get item related values but I want to get all fields value of all items so I used filter by app ID, I'm getting an error Undefined property: PodioItemCollection::$fields

<?php 

require_once '/PodioAPI.php';

$client_id = "xxxx";
$client_secret = "xxxx";
$app_id = xxxx;
$app_token = "xxxx";

Podio::setup($client_id, $client_secret);
Podio::authenticate_with_app($app_id, $app_token);

$item = PodioItem::filter($app_id);
$field_id = 'dashboard-link-2';
$collection = $item->fields[$field_id]->values;

foreach ($collection as $embed) {
  print "Embed id: ".$embed->embed_id."<br>";
  print "Embed URL: ".$embed->original_url."<br>";
}

Here's the full response in 2 items available in APP on JSON format using print $item->as_json(true) . I want to do for each in all fields and their value on the last part of JSON.

Answer 1

You'll want to iterate through the fields array to find the field with the external_id equal to what you are looking for. It look like you are looking for the field with external_id == 'dashboard-link-2'

Edit #1 Added example:

$collection = []
foreach ($item->fields as $field) {
  if ($field->external_id == "dashboard-link-2") {
    $collection = $field->values;
  }
}

Edit#2: Had a look at the Docs, my code is for an older/different version of the Library. Sorry
