Hello PHP,
I am having a problem. I know the area of the problem, but not how to
solve it.
It has to do with a php page with a form on it, and I am trying to
perform an insert query into
my mysql database.
I know that when I "submit" (post) the form, everything goes blank,
and the insert query is not run.
Basically here is my story. Initially I had a page with all in-line
code, that uses includes for connection to the db, and a error
processing page. I also have another include page that has some
functions in it, one of which is for resizing images. That function,
cleverly named resizeImage returns a down-sized height and width,
which get loaded into the database table, along with info on the image
itself (name, location,etc).
this page has php code which reads a directory, finds jpeg images,
does a resizeImage for each image (in a for loop), and then performs
the insert query for each image. I would run the whole thing just by
loading the page (no form tags on this page). Everything works fine,
I call the resizeImage function from the fileloader.php page, the
function is in a page called size_image.php (I use a require for
this).
I decided that I would like to add some flexibility to this page and
create a form where I could enter a parameter (an integer), and click
a button, which would then run this same insert query, and the
resizeImage function, and then tell me if I inserted the records.
I am using a if(isset($_REQU EST['update'])) type construct to respond
to the button click (named 'update').
and use the POST action and $_SERVER[PHP_SELF] as the form.
When I click the button, most of the page runs, and then all goes
blank in the browser, and the records are not inserted into the
database. I am guessing that something in the post blitzes my
variables, etc, so the query never runs, etc.
Below is some of the code in the page - I have an input box for the
parameter, and a button to run the function. I would appreciate any
suggestions.
Thanks,
