Hi! I have a php form and I am using it to update,delete and insert data.I use a drop down to display customer names and when the customer is selected, the form should be submitted with document.frm1.submit(); so that I can get company id of that customer.
Problem is, when I try to update the data and select customer,suddenly the insert query is executing.I tried to put conditions, sending hidden values but nothing seems working.Either the form refuses to submit, or submits accidentally due to document.frm1.submit();
Here is part of my code.Please help me in this regard.
<?PHP
$id=$_GET['id'];
//query to display database values when update link is clicked
$query=mysql_query("SELECT * FROM sales WHERE id='".$id."'");
$row_1=mysql_fetch_array($query);
if(isset($_REQUEST['action_perform']))
{
$id=$_REQUEST['id'];
$tbl = 'sales';
$field = 'number';
$post = $_POST['number'];
$where_clause = "id='".$id."'";
$insert_array = array('cust_id' => $_POST['name'],
'co_id' => $_GET['co_id']);
if($_REQUEST['action_perform']=="delete"){
dbRowDelete($tbl, $where_clause);
header('Location:sales.php?query=delete');
}
if($_REQUEST['action']=="update"){
dbRowUpdate($tbl, $insert_array, $where_clause);
header('Location:sales.php?query=update');
}
if($_REQUEST['action_perform']=="Save"){
$check = check_duplicate($tbl,$field,$post);
if($check > 0){
header('Location:sales.php?query=duplicate');
}
else{
dbInsert($tbl,$insert_array);
header('Location:sales.php?query=insert');
}
}
}
?>

document.gr.submit();
