I want to write a script
if database no this record. It will insert
If database have tis reord. It will update

for ($a=0; $a<count($arr_event_id); $a++)
{    

    $query1 = "SELECT evnt_id FROM sales_roadshow  WHERE evnt_id = '".$arr_event_id[$a]."' ";
	$result1 = mysql_query($query1) or die(mysql_error());
	$row_s1 = mysql_fetch_row($result1);
	$P_numrows1 = mysql_num_rows($result1);
	
	if ($P_numrows1 == 0)
    {
      $res=mysql_query("insert into sales_roadshow1
      (evnt_id , evnt_start , evnt_end , evnt_status , evnt_type , evnt_title)
                            values	(\"$arr_event_id[$a]\",\"$arr_start_date[$a]\",\"$arr_end_date[$a]\",\"$arr_status[$a]\",\"$arr_event_kind[$a]\",\"$arr_event_title_chi[$a]\")") or die(mysql_error());
	 }
	 else
	 {
	   
	    mysql_query("UPDATE `sales_roadshow1` SET `evnt_title`  = '".$this_event_title."' WHERE `evnt_id` = '".$this_event_id."'");
	 }
}  // for

But I don't know why have a problem
Object of class __PHP_Incomplete_Class could not be converted to string
The problem is
mysql_query("UPDATE `sales_roadshow1` SET `evnt_title` = '".$this_event_title."' WHERE `evnt_id` = '".$this_event_id."'");

How can I fix it?

I think you can do it with

mysql_query("UPDATE sales_roadshow1 SET evnt_title = '$this_event_title' WHERE evnt_id = '$this_event_id'");

1) Here in insert query \" double quote is not allowed you must use single quote
2) no need to check record exist or not, just use on duplicate key.
(Note: on duplicate key works only in MYSQL, and you must define primary key or unique for the table)

$res=mysql_query("insert into sales_roadshow1      (evnt_id , evnt_start , evnt_end , evnt_status , evnt_type , evnt_title)                            values	('{$arr_event_id[$a]}','{$arr_start_date[$a]}','{$arr_end_date[$a]}','{$arr_status[$a]}','{$arr_event_kind[$a]}','{$arr_event_title_chi[$a]}') on duplicate key update `evnt_title`  = '".$this_event_title."'") ;

I try this coding. I already set up evnt_id as primary key.
But occur a error
"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '` = ''' at line 3"

What is the eroor mean?

My coding here

for ($a=0; $a<count($arr_event_id); $a++)
{    

    $query1 = "SELECT evnt_id FROM sales_roadshow  WHERE evnt_id = '".$arr_event_id[$a]."' ";
	$result1 = mysql_query($query1) or die(mysql_error());
	$row_s1 = mysql_fetch_row($result1);
	$P_numrows1 = mysql_num_rows($result1);
	
	
      $res=mysql_query("insert into sales_roadshow1

on duplicate key update evnt_title`= '".$this_event_title[$a]."'") the error is on that character before evnt_title, what's this character "`"? delete it and put ' this one cuz it seems like you copied that code so that's y it doesn't read that character.

Thanks.......
But I back to my original problem again

"Catchable fatal error: Object of class __PHP_Incomplete_Class could not be converted to string in /home/germanpo/public_html/roadshow/upload_excel_import.php on line 78"

}

Is that error in one of your classes? if you have this page "/home/germanpo/public_html/roadshow/upload_excel_import.php" plz show us the code on line 78 so we can sort it out

I sent all coding to your message box.
Please help me~

Okay, m working on it. I'll let you know once m finished

Okay, m working on it. I'll let you know once m finished

THANKS~~~~~~~~~

You have not read my last post properly,
You must use single quote instead of double quote. Also you need to use braces {}
like '{$arr_promoter_count[$a]}'
do you use \" only use '


Post your table structure in sql format here, I will try to debug your query here.
