Forms and strings using $PHP_SELF

foxden

Hi all,

I'm fairly new to PHP and have a general question. I am having problems after reading information into a form from MySQL. I can read it in and display fine, but if I want to modify the information, the MySQL UPDATE puts the old variable back into that row.

Any ideas on what I'm doing wrong would be greatly appreciated.

Thanks,
Josh

eh?

You need to be more specific.

Might want to post the code in question.

Sorry about that. I've got simple html forms that have a name=\"something\" and value=\$something\"

This works fine for my initial query, I extract data out of MySQL and it populates the above form fields, but if I want to change a textfield or textarea and update that change back into the Db, the initial \"$something\" gets "updated" into the Db instead of the change(s) that I just made.

When you say 'populates the form' you mean yhat you are changing the value='$something' right?

Try unsetting the $something vars and then reseting with the pulled data.

Are the $something vars session vars?

Post a simplified code version and lets have a look.

How do you unset the var?

$form_block = " <form method=\"post\" action=\"$PHP_SELF\" enctype=\"multipart/form-data\">

unset($vendor_name);

I think that will do it.

Thanks!
