Hi All,

How to upload multiple files at the same time in rest API. When I am going to select from file picker I want that count how many files picked how to get that count or is there any other options, how to achieve it. Please guide me.

 

For your reference,

<oj-file-picker select-on='click' on-oj-select="[[$listeners.ojFilePickerOjSelect2]]">
              <oj-button slot='trigger' chroming="solid">
                 Choose File
              </oj-button>
  </oj-file-picker>

sample json passed in rest API:

 { "p_sch_line_id":"1025",
          "p_reason":"reason2",
          "p_remarks":"From Postman v1",
        "Attachment_details":[
         {"file_name":"sample1",
         "file_type":"txt",
         "file_data":"Rm9vdG5vdGUgMTogVGhpcyBpcyBzaW1pbGFyIHRvIHdoYXQgaXMgYXZhaWxhYmxlIGZvciBYTUwgZGF0YSB1c2luZyB0aGUgRG9jdW1lbnQgT2JqZWN0IE1vZGVsIChET00pLCBhIGxhbmd1YWdlLW5ldXRyYWwgYW5kIHBsYXRmb3JtLW5ldXRyYWwgb2JqZWN0IG1vZGVsIGFuZCBBUEkgZm9yIGFjY2Vzc2luZyB0aGUgc3RydWN0dXJlIG9mIFhNTCBkb2N1bWVudHMgdGhhdCBpcyByZWNvbW1lbmRlZCBieSB0aGUgV29ybGQgV2lkZSBXZWIgQ29uc29ydGl1bSAoVzNDKS4="
