Add a picture to an event via the eventbrite API ?

[Philippe Oursel]

Hi !

I am actually working on a web application which uses the eventbrite api, I don't have any problem about creating an event with all the necessary informations, same for displaying them when I need to. 

My problem is about the event picture, the event page of an event on eventbrite is kinda "sad" without a picture. 

While reading the eventbrite api documentation I found out there is a "event.logo_id" parameter but I don't know how to use it and what it represent. Does anyone have more information about that ? Or is there any way to upload a picture for an event via the Api ?

Thanks in advance,

Philippe Oursel

PS : I code in PHP

Hi,

First of all thanks for your help, 

So I manage to get my "upload_token" and my "upload_url" link but I struggle at the step 2, I understand how it work but I doesn't even know how to start to make it work with "curlfile".

Maybe if it's not too much to ask can you give me an example code of what I will look like ?

hello,

I have created a snippet for you, you can try this code https://pastebin.com/UTrDPhKX

I ask you a lot sorry (still a beginner) but can you explain these ligne :

1. $eventBriteModel = new zerolfc\eventbrite\HttpClient( TOKEN );
2.  
3. $mediaResult = $eventBriteModel->get('/media/upload/', [
4.   'type' => 'image-event-logo'
5. ]);

1.    $uploadResult = $eventBriteModel->post('/media/upload/', [
2.     'upload_token' => $mediaResult['upload_token'],
3.    ]);

Also you upload the picture with curl just before, so why do you have to do it again with $uploadResult ? There is something that I miss especially at the first ligne where you define $eventBriteModel

[Philippe Oursel]

Ok, after re reading the api documentation I understand the last part :

1.    $uploadResult = $eventBriteModel->post('/media/upload/', [
2.     'upload_token' => $mediaResult['upload_token'],
3.    ]);

Correct me if I'm wrong but this is for notify the API that the upload work has completed, but I still doesn't understand this part to adapt it for myself :

1. $eventBriteModel = new zerolfc\eventbrite\HttpClient( TOKEN );
2.  
3. $mediaResult = $eventBriteModel->get('/media/upload/', [
4.   'type' => 'image-event-logo'
5. ]);

Im not sure if you are familiar with composer. https://getcomposer.org/doc/01-basic-usage.md#autoloading

If you use composer then you can use PSR-4 autoloading.

To download you need to install composer to your laptop. then you can use below code to install the package:

composer require zerolfc/eventbrite-sdk-php

then in your file

require 'vendor/autoload.php';

$eventBriteModel = new zerolfc\eventbrite\HttpClient( TOKEN ); // zerolfc\evenbrite is a namespace

Or you can download the file from github.

Here is the link for the package: https://packagist.org/packages/zerolfc/eventbrite-sdk-php

This is how eventbrite `media/upload` works.

1) Retrieve the upload token that will include the upload data to their CDN Amazon S3

$mediaResult = $eventBriteModel->get('/media/upload/', [

  'type' => 'image-event-logo'

]);

2) Upload the image to their CDN using the CURL code

3) Notify the API upload has completed. This is when you use `upload_token`. Eventbrite is probably checking whether the upload_token matches with the Amazon Key and the image has been uploaded.

$uploadResult = $eventBriteModel->post('/media/upload/', [

    'upload_token' => $mediaResult['upload_token'],

]);

   

hope that helps

if you notice its HTTP method GET not POST, so this is to get the upload token

After some struggle it's ok everything work !!!!

I just can't get this to work at all. Curl gives me no information back, either as an error or a response. And then a POST request with the upload_token tells me 'upload_token' is an unknown parameter and it requires a 'type' parameter.

[zerolfc]

can you post your php code?

[mi...@generalpie.com]

I initially tried to use guzzle multipart but that kept giving me conflicting query parameter errors:

See here
https://stackoverflow.com/questions/47644875/struggling-with-s3-multipart-upload-guzzle-for-eventbrite

I then just switched to using your curl code

And then trying to make the final request using guzzle

I've had to chop out a few things here but this->client is the guzzle client

in your $postFields file, make sure its the tmp_name path NOT the full image path

 $_FILES[ {input-name} ]['tmp_name']

[mi...@generalpie.com]

I'm not using a form, this is an image that is already on the server executed by a cron job, so no tmp and no $_FILES
