POST multiple images from PHP

[kevinvennitti]

Hi there!

I am trying to send multiple images to PlantNet API in PHP, and thanks to the doc, everything is fine with one image from an HTML input file:

$data = array(
  'organs' => 'flower',
  'images' => makeCurlFile($_FILES['images']['tmp_name'][0])
);

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$response = curl_exec($ch);

curl_close($ch); 

But I can't find the right way to send multiple files:

• Sending an array of organs and/or images does not work (Array to string conversion error in CURLOPT_POSTFIELDS)

  // This does not work
  $data = array(
  'organs' => [
  'flower', 
  'flower'
  ],
  'images' => [
  makeCurlFile($_FILES['images']['tmp_name'][0]), 
  makeCurlFile($_FILES['images']['tmp_name'][1])
  ]
  );

• Sending "organ_1", "organ_2", "image_1", "image_2" does not work (not recognized)

  // This does not work
  $data = array(
  'organ_1' => 'flower',
  'organ_2' => 'flower',
  'image_1' => makeCurlFile($_FILES['images']['tmp_name'][0]),
  'image_2' => makeCurlFile($_FILES['images']['tmp_name'][1])
  );

What did I missed? 🙂

Hi,

For such a case we recommend using Guzzle library, as in this example : https://github.com/plantnet/my.plantnet/blob/master/examples/post/php/run.php
