I believe you are missing a colon on line 36 -

C:\documents

Yep - you must use isset. In order to solve this, you can send the form to a file handler file - this is a better solution as it prevents resubmitting the form on page refresh - a problem in itself.

It also looks like you have a case mismatch.

Your post is 'Name' and your if(isset($_POST)) is 'name'

Same goes for the other POST variables. These are case sensitive, I believe.

Also, line 53 is missing a ) before the ;

maybe repost your new code, please?

if you have made the changes that we have talked about, there should be some significant naming changes. If you are still getting the above error, then yes it would be helpful to have a new code to look at to see where you are having problems.

Yeah I noticed that a minute after I posted the code, I changed but the problem hasn't solved..I suppose that I somehow, have to use the isset in _$Files too..

Ulfang 0 Newbie Poster · Answer 2 · 2012-09-10T20:14:43+00:00

Can you please explain me how can I do this??Because I am new in php...

Ulfang 0 Newbie Poster · Answer 3 · 2012-09-10T20:24:36+00:00

And something else, if somebody can help..When i upload something, it must be added in my database automatically, right? I ask because , although i have these tables and fields in my database, it is not updating..

Ulfang 0 Newbie Poster · Answer 4 · 2012-09-10T20:36:51+00:00

You are right ryantroop..I changed them already! :)

Ulfang 0 Newbie Poster · Answer 5 · 2012-09-10T20:43:55+00:00

I just put an "image_" in front of every field( ex $image_name)..Do you want to repost it?

<?php

//This is the directory where images will be saved
$target = "uploads";
$target = $target . basename( $_FILES['photo']['name']);

The upload works fine..the only problem is that when I enter for the first time I get the message that I mentioned in the beginning..Probably something with the isset..

I still think that since line 9 is:

<input type='input' name='Name'> (notice the upper case 'Name')

Then on line 40, you use $_POST['name'] (notice the lower case)

Try changing that, as I believe these are case sensitive.

Ulfang 0 Newbie Poster · Answer 8 · 2012-09-10T22:02:29+00:00

same error..As the upload works and the only problem is that I get this error message as I enter the page, I still believe that I must put something containing isset..the only problem is that i dont know what..

ryantroop 177 Practically a Master Poster · Answer 9 · 2012-09-10T22:10:53+00:00

if it's still the same lines getting the error (37 and 56), then I feel it's line 37 causing the problem.

You can try changing it to

$target .= basename($_FILE['photo']['name'])

then try:
die("$target")

and see what you get (should be a blank screen with a path name). If the path name is not what you expect, then you need to fix that.

I made this change and I get an error...

Ulfang 0 Newbie Poster · Answer 11 · 2012-09-10T22:22:44+00:00

I had the same problem with undefined index when I was working the login page. I added the isset in _$post it was solved.Do you know probably a way to add in there?

ryantroop 177 Practically a Master Poster · Answer 12 · 2012-09-10T22:33:06+00:00

What error?

If you want to check if post is set, then you simply use

if(isset($_POST)) {
//do stuff

}

Not sure how that would really help, other than preventing people from accessing the script without posting something.

the undefined index error...

Ulfang 0 Newbie Poster · Answer 14 · 2012-09-10T22:44:13+00:00

Probably because when I first enter the page it has no value I get this error message.When I upload an image and after it works properly..
