Problems executing PHP after a form has been submitted..

basquille · August 6, 2008

Hi all,

First post so be easy on me!

Below is a PHP page containing a form, some basic HTML and a PHP script (the PHP script is used to upload an image). The script and page works in general in that it has successfully render the page and the form area can upload the image and add the location of it to the database.

But the problem is that after carrying out the upload, I need to reload the page again for the image to appear. For reasons I won't go into here, I don't want to use the javascript "location.reload();" method to refresh the entire page.

I have figured out that when I load the page, it successfully enters the resultset containing the image locations, and does the task subsequently being drawn. But when I carry out an upload of an image on the form, that resultset is not entered again. Is it a problem with re-connecting to the database or that the connection has died?

The important area is where there is am '!!!! IMPORTANT !!!!' comment above it.. the rest is merely just to show the process. The area in question will work (as it enters the resultset) when the page is first loaded, but not when the form is submitted and the page is subsequently reloaded (as it doesn't enter the resultset).

Any suggestions or comments are very much welcome and appreciated.

PS - my database settings, that are correct, are stored in the 'db_include.php' file.

Any suggestions
