storing to db via form + optional image upload

hi experts,

i am referring to [URL=http://www.webdeveloper.com/forum/showthread.php?t=96532]this thread[/URL] by [B]bokeh[/B] entitled [B]“How to: Upload images using PHP”[/B].

i want to achieve a solution where one can add a news item to a mysql db and [B]optionally[/B] attach a picture too.

so i modified the [B]upload.form.php[/B] and added 2 more form fields: “headline” and “text”.

next i edited [B]upload.processor.php[/B] so that additionally the values of the fields “headline” and “text” as well as the location of the uploaded image on the server get stored in a mysql table.

that works perfectly as long as there is a picture attached and it doesn´t exceed the $max_file_size.

since i want to make the image upload optional i tried some [B]if-else statements in upload.processor.php[/B] to avoid getting errors when there is no pic attached.

no surprise to me that none of my attempts worked so i´m kindly asking for your help to achieve something like this:

[code=php]if (there was a picture selected in upload.form.php) {
// …do what bokeh´s original script does (including error checking) + store info in db…
} else {
// …only store the values of the fields “headline” and “text” into the db and ignore that an image is missing…[/code]

my problem is to find the right [B]if-statement[/B]. i tried [B]if (strlen($_FILES[$fieldname][‘tmp_name’]) > 1)[/B] but then i don´t get any error msg when max file size is exceeded.

any ideas?

thanks in advance,
jogol
