very simple cms form problem [MODIFIED and formatted :)]

amplexus · July 20, 2012

Hi,

I'm creating a website, and want to have text on a portion of each page be editable by a non-tech, average user. I've created a form, and I've got it to work. I'm using .txt files.

what I've tried to do is create one page that has all of the pages' editable areas on it, each one displaying the current text, and a submit button to make the changes live. in the code, the php to generate the forms is after each of the text lines beginning with "Edit copy".

Problem: when you click any of the submit buttons, all of the areas update. is it that i need to make each separate form code have a different input name?

here;s my code, formatted to make it easier to read, since I was completely exhausted before.

what's wrong?

hakimserwa · July 20, 2012

you can either use hidden input together with if statements as a token to diffreciate which form was set when the submit battom was pressed.

if(isset($_post['hidden'])){

do something

}

or change the names of the submit batton to something specific and use it as th token to do the above job.

if(isset($_post['kiwanyed'])){

do something

}

Donald. · July 20, 2012

This is not what Pikachu2000 meant when he said to parse it with the code tags and formatted it properly. You also need to indent it so it flows easily when reading what it does.

so, In the last bit you can see (I hope)that I've changed the first form to have a name of "home" and adjusted the $_POST value to "home" as well. this has the effect of changing just the one value, and leaving the other forms intact. however, it also seems to change the .txt value to a blank. I'm thinking that the fwrite value needs to be changed, am I barking up the right tree here?

Donald. · July 20, 2012

Each if($_POST['Submit']) should have a different unique name so it knows which one you're actually wanting to run. Name them Submit_index, Submit_about, Submit_rentals, you get the deal. You'll also need to change the name of each submit button to match accordingly.

Is it changing all the text files into blank ones or just the one you hit submit?

amplexus · July 20, 2012

and so I've got this, and thank you for the changing names idea, I also figured out that I needed to change the textarea name.

it seems to be working okay...

which seems to be working fine.

if you're so inclined, do you see any problems? I know about security,and will be adding a passcode protection before going "live"

okay, have to revive this thread. what I've discovered when I gave this to the client is that they LOVE to use contractions in their copy.

Every time they put an apostrophe, PHP puts a backslash, so it's becomes it\'s.

is there a way to tell php that this is a .txt file it is writing to?

Pikachu2000 · September 12, 2012

So magic_quotes_gpc must be on, then?

amplexus · September 12, 2012

the site is hosted by Godaddy. is there a way to turn something like that off?

Christian F. · September 12, 2012

Any host running with Magic Quotes still is extremely outdated, and as such I really recommend you to change hosts. (Not to mention all the other reasons, SOPA/IPROTECT being one of them.)
