Hey,
I have stumbled upon something i have never experienced before.

When creating an input function i found an issue of when the input was created it then put in the variables in to the new record but about 5 seconds later it created a blank entry below it containing no information at all.

I seperated the Input from the function in to its own script and found there was still a problem with it and it still occured.

i stripped down the input query and regardless of how many of the fields i tried to insert and regardless of them being variables or hard coded results it still created the duplicate record.

The last thing i did was to remove the session_start(); and this instantly resolved the issues. i rebuilt the query and it still worked fine obviously without the users name.

i have coded inputs which use session variables before and have never came across anything like this... any help would be greatly appreciated..

Regards
Jim

Hello,

Instead of using

if ($_GET['status'] == 'insert_job_confirm') {

why dont you check for submit button ...

if ($_POST['Submit']) {

hth
[/quote]

Thanks for the advice,
at current the main reason i dont do that is because i have multiple parts to it not just purely variables on that modify script. theres another part that has to be seperate so if i did set it on post then it would impact that.

Regards
Jim

just a work around

before inserting check if the values are set...this will avoid blank record going in....

if(trim($name) && $priority......) {
$query_insert_job = "INSERT INTO job (name, priority, frequency, frequency_note, runs_in, description, application, instructions, date_created) VALUES ('{$name}', '{$priority}', '{$frequency}', '{$frequency_note}', '{$runs_in}', '{$description}', '{$application}', '{$instructions}', now())";

}
