i know we should use TIdMultipartFormDataStream to include the photo but i dont know how, it supposed to be something like this UploadParams.AddFile('photo', Edit11.Text);

Answer 1

i know we should use TIdMultipartFormDataStream to include the photo

Yes.

but i dont know how

TIdMultipartFormDataStream only has 3 methods for adding data fields:

• AddFormField() (which takes data as a string or a TStream)
• AddObject() (which is deprecated)
• AddFile()

Since you want to upload a file, it makes sense that you should use AddFile() (unless you open a TStream to the file, then you can use AddFormField() instead).

it supposed to be something like this UploadParams.AddFile('photo', Edit11.Text);

Assuming Edit11.Text contains the full path and filename to the photo file that you want to upload, all you need to change is 'photo' to 'profile_pic', since that is the name of the input field in your WebKit example:

UploadParams.AddFile('profile_pic', Edit11.Text);
