Hi Brian, Thanks buddy. I will be using the first one. :) Cheers :) Zaid Brian Etheridge <Brian.Etheridge@xxxxxxxxxxx> wrote: Hi Zaid, It is not a problem particularly to do with pop-up windows and I have approached it in two ways on projects I have worked on. Firstly, on the client side. This involves setting a global javascript flag which is set when the form is submitted. Thus, when the user tries to submit the form again you check the status of the flag and tell them it has already been submitted and do nothing. Secondly, from the server side. In this case you generate a unique id which is written to a database table called something like pageTransaction, with a status of 'new'. You insert the unique id into a hidden field in the page. When the page is submitted the first thing you do is check the status of the pageTransaction row, if it is still 'new' then you update it to 'old'. If the row is already 'old', then it means the user has resubmitted the form and you reject the transaction with a suitable message. Which one is best? In the first case we were dealing with an intranet situation where all users were using IE, they all had javascript turned on, and we had total control. So I think the client side check was just about justifiable. However, I think the server side technique is more reliable and probably the way to go unless there are any better suggestions from other developers. The second technique certainly seemed to work perfectly well for our project.

Hi - All, I have posted a form to a PHP file in a new window with target attribute. My problem is that my application should not allow user to post the form again. User should close the window and then only (s)he can post the form again. Can we get the handle of the opened window? If we use window.open then we will get the handle of that window but I am unable to post data with window.open. Any idea on posting data to modal windows. Not as parameters but as $_POST. Please suggest. Regards, Zaid --------------------------------- Need a vacation? Get great deals to amazing places on Yahoo! Travel.
