画像をアップロードして、アカウントの現在のセッションの「ID」と一緒にデータベースに保存する方法

Question

以下のコードは、ファイルの拡張子とともに画像のファイル名をデータベースに保存することができます。私の問題は、IDを取得して画像と同時に保存する方法がわかりません。ここに私のコードは、これまでのところです：
セッションPHP

$id = $_SESSION['id']; 

アップロード画像のためのモーダル：

    <!-- Modal content--> 
        <div class="modal-content"> 
         <div class="modal-header"> 
         <button type="button" class="close" data-dismiss="modal">&times;</button> 
         <h4 class="modal-title">Profile Picture</h4> 
         </div> 
         <div class="modal-body"> 
         <form id="upload_image" enctype="multipart/form-data" action="" method="post"> 
            <div id="filediv"> 
             <label>Chose image:</label><input style="margin: 0 auto;" name="file3[]" type="file" id="file3"/> 
            </div> 
           <input type="text" name="prop_number" value="<?php echo "1"; ?>" style="display:none" /> 
           </form> 
         </div> 
         <div class="modal-footer"> 
          <button type="button" class="btn btn-success" data-dismiss="modal" id="upload22"><i class="fa fa-upload"></i> Upload</button> 
         <button type="button" class="btn btn-default" data-dismiss="modal"><i class="fa fa-close"></i> Close</button> 
         </div> 
        </div> 


        </div> 
       </div> 

のjQueryコード：データベースへ

//Upload Picture 
$('#upload22').click(function(e) { 
    var selper = $('#selectperson').val(); 
    var trythis = $('#file3').val(); 
    //if(selper == '' || selper == 'Select Person'){ 
    //sweetAlert({title: 'Please Select Person', text: 'Please choose a file', type: 'warning',  closeOnConfirm: true, showLoaderOnConfirm: true, });  
    //} 
    if(trythis == ''){ 
    sweetAlert({title: 'Missing File.. File is required', text: 'Please choose a file', type: 'warning',  closeOnConfirm: true, showLoaderOnConfirm: true, });  
    } 
    else{ 
    var data1 = new FormData(); 
     jQuery.each(jQuery('#file3')[0].files, function(i, file) { 
      data1.append('file3[]', file); 
     });  
    var other_data = $('#upload_image').serializeArray(); 
     $.each(other_data,function(key,input){ 
      data1.append(input.name,input.value); 
    });  

     jQuery.ajax({ 
      url: 'queries_james.php', 
      data: data1, 
      cache: false, 
      contentType: false, 
      processData: false, 
      type: 'POST',   

      success: function(response){ 
       sweetAlert({title: 'Successfully uploaded.', text: 'Thank you', type: 'success',  closeOnConfirm: false, showLoaderOnConfirm: true, }, function(){ window.location.href = 'add_gen.php'; });  
       updater(); 
      } 
     }); 
    } 
});

PHPコード：

$findings= pg_query($connection, " 
    insert into tbl_profile_picture(id,name,emp_id) 
    values ((SELECT COALESCE(max(id),0)+1 FROM tbl_profile_picture),'$link1','".$_SESSION['id']."') 
    ");
