amazon s3 - create a temp image file for upload -


I have created an HTML5 image uploader using the canvas. I have image data 

  Canvas.toDataURL ();   
 Which  
  data: image / png; Base64, & lt; Base64image string & gt;   
 I have sent the above data to php which will be used to upload an image to the Amazon server.  
 I usually  
  file_get_contents (path_to_file_to_upload); Amazon SDK is used to work   
 and how can I now convert the code to file  file_get_contents  for uploading base 64 image data file.  
 I do not have permission to create a file in the server. Create a temp image and get  file_get_contents  data from that temp file ?? Pass the return value of base64_decode () instead of file_get_contents in the AWS SDK.

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
