Javascript file submission causing server error in php script -


i've been going mad past month trying build page submit pdf asynchronously our server. i'm experienced programmer, never worked in web-dev or in php or javascript.

the javascript submission function follows:

function sendfile(event) {     $("#submitform").hide();     var formdata = new formdata();     var file=$("#journal")[0].files[0];     formdata.append("document", file);     $.ajax("converter.php", { data:formdata, processdata:false, datatype:"text", method:"post", success:function(data, textstatus, jqxhr){         if(data.length == 8)         {             $("#key_input").val(data);             $("#key_submission").submit();         }         else         {             $("#response").html(data);         }     } });

it submits server php script reaches line

if(isset($_post['document']))

the program crashes , internal server error. causing crash?

this should done $.ajax() way:

$.ajax({ //<------"{" object should passed here missing "{"    url:"converter.php", //<-----"url:" missing.    data:formdata,     contenttype:false, //<-----this needed file upload    processdata:false,     datatype:"text",     type:"post", //<------should type not method     success:function(data, textstatus, jqxhr){      if(data.length == 8){             $("#key_input").val(data);             $("#key_submission").submit();      }else{             $("#response").html(data);      }    }  });

if trying upload file contenttype:false needed processdata:false.
