Upload file with iframe loos session user and session id in wwv_flow_files

Question

Hello every one, hope someone could help us with this problem.
What we are trying to do is to upload a file from a jquery dialog in a appex page by redirecting the POST action of the wwvFlowForm to the iframe.
*1. In the javascript there is the function call to open my modal window with the input*
function add_fichier_form(numeroProjet,idCat){
     $("#div_upload_fichier").dialog(
                modal : true ,
                autoOpen : false ,
                resizable: false ,
                width: 700         
       $('#div_upload_fichier').parent().appendTo('#div_base');
      $('#upload_button').unbind('click').click(function(){           
          if ($('#P4010_FILE_FICHIER').val() != '') {
               $('#upload_iframe_v2').unbind('load').load(function () {
                    $('#upload_status').html(' déplacement du fichier...');
                    // move the file
                    $('#upload_status').html('Fichier transféré avec succès');
                    //file transfer ok
                    //calling the javascript function to add everything in my own table;
                                 //we see the file in the  wwv_flow_file_objects$ without
                     add_fichier_form_db();
               // set the form target to the iframe, submit, then remove the target
               $('#wwvFlowForm').attr('target','upload_iframe_v2').submit().removeAttr('target');
               $('#upload_status').html(' Téléchargement du fichier...');
          }else {
               alert('Veuillez sélectionner un fichier');
     $("#div_upload_fichier").dialog("option", "title", "Ajout d'un fichier");
        $("#div_upload_fichier").dialog("open");
       }*2. At this point we see the file in the table but without the user and session credential*
select *
    from wwv_flow_file_objects$
The result is that the field security_group_id is assign to 0 AND created_by = APEX_PUBLIC_USER
*3. add_fichier_form_db(); the javascript function making the ajax call to a procedure plsql*
function add_fichier_form_db(){
         //alert ('Dasn fichier form db');
     vNumeroProjet = document.getElementById('P4010_CAT_NUMERO_PROJET').value;
     vIdCat = document.getElementById('P4010_CAT_ID').value;
     vFichierNom = document.getElementById('P4010_NOM_FICHIER').value;
     vFichierDesc = document.getElementById('P4010_DESC_FICHIER').value;
     vFichierFile = document.getElementById('P4010_FILE_FICHIER_NAME').value;
     var ajaxRequest = new htmldb_Get(null , 300, 'APPLICATION_PROCESS=ADD_FICHIER_FORM_DB', 4010);
     ajaxRequest.add( "P4010_CAT_NUMERO_PROJET", vNumeroProjet);
     ajaxRequest.add( "P4010_F_CAT_ID", vIdCat);
     ajaxRequest.add( "P4010_FICHIER_NOM", vFichierNom);
     ajaxRequest.add( "P4010_FICHIER_DESC", vFichierDesc);
     ajaxRequest.add( "P4010_FILE_FICHIER_NAME", vFichierFile);
      var gReturn = ajaxRequest.get();
     if (gReturn){
          $x("getlistfichier").innerHTML = gReturn;
          closeForm();
     }else{
          alert ('Problèmes dans le call Ajax ADD_REPERTOIRE_FORM_DB \n La valeur retournée est: \n' + gReturn);
}*4. PLSQL PROCEDURE *
h1. WHEN the query is executing it's return ORA-01403: no data found. WHY ????
PROCEDURE P_ADD_FICHIER_FORM_DB(
            P_NUMERO_PROJET number,
            P_CAT_ID number,
            P_FICHIER_NOM varchar2,
            P_FICHIER_DESC varchar2,
            P_FILE_FICHIER_NAME in varchar2)
AS
  vNumeroProjet number;
  vFichierNom varchar(255);
  vFichierDesc varchar(2000);
  vCatId number;
  vActif number;
  vDocSize number;
  vNomUsager varchar(10);
  vDateCreation date;
  vFichierTypeId number;
  vNomReel varchar2(1000);
  vNomReel2 varchar2(1000);
  vCurVal number;
  BEGIN
    SELECT FILENAME,DOC_SIZE,CREATED_ON
    INTO
    vNomReel,vDocSize,vDateCreation
    FROM WWV_FLOW_FILES
    WHERE FILENAME = P_FILE_FICHIER_NAME;
/*GET ERROR sqlerrm:ORA-01403: no data found */
  END P_ADD_FICHIER_FORM_DB;h4. hope someone help us soon
Thanks in advance

Answer 1

Finally we find what was wrong so i give you the solution.
In the javascript on the function add_fichier_form
We need to append the div of the form to the default form of apex wwvFlowForm
so the line*
$('#div_upload_fichier').parent().appendTo('#div_base');
should be change to*
$('#div_upload_fichier').parent().appendTo('#wwvFlowForm');Edited by: jocbed on 2012-01-26 11:08
