รบกวนเรื่องการ upload file ไม่ได้ครับ ช่วยทีรบกวนพี่ๆ PHP Programmer ทุกท่าน

//เมื่อกดปุ่ม upload file จะแสดงฟอร์ม เพื่อใช้อัพโหลดไฟล์ขึ้นไปบน server

if($_POST['upload']){
	echo'<form action="" method="post">';	
	echo'Welcome <font color="blue">'.$_SESSION['name'].'</font> to Customer Support ';
	echo'<input type="submit" name="create" value="Create Account">';
	echo'<input type="submit" name="upload" value="   Upload File   ">';
	echo'<input type="submit" name="logout" value="      Logout      ">';
	echo'</form>';
	echo'<p>';
	echo'<form action="" method="post">';
	echo'<table width="100%" align="center">';
	echo'<tr>';
	echo'<td align="right">File Upload : </td>';
	echo'<td><input type="file" name="file_1" ></td>';
	echo'</tr>';
	echo'<tr>';
	echo'<td align="right">File Name(or Description) : </td>';
	echo'<td><input type="text" name="file_name" size="50"></td>';
	echo'</tr>';
	echo'<tr>';
	echo'<td align="right">Supplier(?) : </td>';
	echo'<td><select name="sup_ID"><option value="">---- Please Select Supplier ----</option>';
	echo'<option value="1">KPNS</option>';
	echo'</select></td>';
	echo'</tr>';
	echo'<tr>';
	echo'<td align="right">File Type : </td>';
	echo'<td><select name="file_type"><option value="">---- Please Select Type ----</option>';
	echo'<option value="PO">Purchase Order</option>';
	echo'</select></td>';
	echo'</tr>';
	echo'<tr>';
	echo'<td align="right">Upload by : </td>';
	echo'<td><input type="text" name="upload_by" value='.$_SESSION['name'].' size="50" disabled></td>';
	echo'</tr>';
	echo'<tr>';
	echo'<td>&nbsp;</td>';
	echo'<td><input type="submit" name="import" value="Upload Now!"><input type="reset" name="reset" value="    Clear    "></td>';
	echo'</tr>';
	echo'</table>';
	echo'</form>';
}

//ถ้ากดปุ่ม upload now จะแสดงหน้าจอยืนยันข้อมูล ก่อนการ อัพโหลด

if($_POST['import']){
	
	echo $file_temp = $_POST['file_1'];
	if(copy($_FILES["file_1"]["tmp_name"],"FileUpload/".$_FILES["file_1"]["name"])){
		echo'copied';
	}else{ 
		echo'Not complete'; 
	}

	 $userfile_name = $_FILES["file_1"]['name']; // file name  
	 $userfile_tmp  = "FileUpload/".$_FILES["file_1"]['tmp_name']; // actual location  
	 $userfile_size  = $_FILES["file_1"]['size']; // file size  
	 $userfile_type  = $_FILES["file_1"]['type']; // mime type of file determined by php  
	 $userfile_error  = $_FILES["file_1"]['error']; // any error!. get reason here 
	 $date1 = date("Y-m-d H:i:s");
	
	//echo $sql_upload = "insert into asmt_file_upload(FileName,FileType,FileSize,FileExtension,FilePath,FileUploadBy,FileUploadDate,Supplier)
	//values('$_POST[file_name]','$_POST[file_type]','$userfile_size','$userfile_type','$userfile_tmp','$_POST[upload_by]','$date1','$_POST['sup_ID']')";
