Add PETA Vegan Approved List to OBF

[philipbrembeck]

Proposed changes

Add the PETA Vegan Approved list to all products from OBF and match them.

PETA Vegan Approved does not support food/cosmetics, etc. but only clothing, so it's not relevant.
Anyways, this is a way to search the Approved Manufacturers (maybe for future projects):

<?php
ini_set("display_errors", 1);
ini_set("display_startup_errors", 1);
error_reporting(E_ALL);

$VAR = $_GET['company'];
if (empty($VAR)){
  header("Content-Type: application/json;charset=utf-8");
  echo '{
    "STATUS": "BAD_REQUEST"
}';
  exit();
}
$curl = curl_init();

curl_setopt_array($curl, [
  CURLOPT_URL => "https://petaapprovedvegan.peta.org/search-peta-approved-vegan/",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "{\"action\":\"facetwp_refresh\",\"data\":{\"facets\":{\"search\":\"$VAR\",\"categories\":[],\"country\":[],\"pagination\":[]},\"frozen_facets\":{\"search\":\"soft\"},\"http_params\":{\"get\":{\"_search\":\"$VAR\"},\"uri\":\"search-peta-approved-vegan\",\"url_vars\":[]},\"template\":\"wp\",\"extras\":{\"sort\":\"default\"},\"soft_refresh\":0,\"is_bfcache\":1,\"first_load\":0,\"paged\":1}}",
  CURLOPT_HTTPHEADER => [
    "Accept: */*",
    "Content-Type: application/json"
  ],
]);

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  $peta = json_decode($response)->template;
  $petali = strip_tags($peta, "<h2><div>");
  $first_step = explode( '<div class="company-filter__companies">' , $petali );
  $second_step = explode("</div>" , $first_step[1] );
  $h2 = $second_step[0];
    $dom = new \DOMDocument();
    $dom->loadHTML('<?xml encoding="utf-8" ?>' . $h2);
    $array = [];
    foreach ($dom->getElementsByTagName("h2") as $node) {
      if ($node->textContent !== "No Companies Match Your Search"){
        $array["STATUS"] = "COMPANIES_FOUND";
        $array["PETA_VEGAN_APPROVED"][] = $node->textContent;
      }
      else {
        $array["STATUS"] = "NO_COMPANIES_FOUND";
      }
    }
    header("Content-Type: application/json;charset=utf-8");
    echo json_encode($array, JSON_UNESCAPED_UNICODE | JSON_PRETTY_PRINT)."\n";
}
?>

But I did not stop there, PETA has also a list of Cruelty-Free Cosmetics and personal care products:
https://crueltyfree.peta.org

I contacted them and while they support the idea, they don't give out a JSON list or anything like that (apparently it is, because it's updated too often? I didn't really get it.)
But I worked my way through their website and got an access point - more or less.
We could access this list like every 4-5 days via a cronjob and then save the results to a separate JSON file which we could also integrate into our API:

<?php
$curl = curl_init();

curl_setopt_array($curl, [

    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "POST",
    /* Security is the AJAX-Security Code generated by PETA and might need to be changed, for faster testing replace "all" with "50"*/
    CURLOPT_POSTFIELDS => "security=74eceaf085&action=dynamic_filtering&sort=companies-dont-test&per_page=all",
    CURLOPT_HTTPHEADER => [
        "Accept: */*",
        "Content-Type: application/x-www-form-urlencoded",
    ],
]);

$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
    echo "cURL Error #:" . $err;
} else {
    $ul = json_decode($response)->html;
    $petali = strip_tags($ul, "<li>");
    $peta = preg_replace("/\n|\t/", "", $petali);

    $dom = new \DOMDocument();
    $dom->loadHTML('<?xml encoding="utf-8" ?>' . $peta);
    $array = [];
    foreach ($dom->getElementsByTagName("li") as $node) {
        $array[] = $node->textContent;
    }

    $output = [];
    array_walk($array, function ($entry) use (&$output) {
        /* PETA Business Friend & Features PETA Logo */
        if ("FL" == substr($entry, -2)) {
            if(!empty(substr($entry, 0, -2))){
              $output["PETA_DOES_NOT_TEST"][] = substr($entry, 0, -2);
            }
        } 
        /* Features PETA Logo */
        elseif ("L" == substr($entry, -1)) {
            if(!empty(substr($entry, 0, -1))){
              $output["PETA_DOES_NOT_TEST"][] = substr($entry, 0, -1);
            }
        }
        /* PETA Business Friend */
        elseif ("F" == substr($entry, -1)) {
            if(!empty(substr($entry, 0, -1))){
              $output["PETA_DOES_NOT_TEST"][] = substr($entry, 0, -1);
            }
        }
        /* Does not test on animals */
        else {
            $output["PETA_DOES_NOT_TEST"][] = $entry;
        }
    });

    header("Content-Type: application/json;charset=utf-8");
    echo json_encode($output, JSON_UNESCAPED_UNICODE | JSON_PRETTY_PRINT)."\n";
}

?>
