Did I setup mySQL table properly? + Password question.

OK, this is really just an exercise for me to familiarize myself with how this all works and setting things up properly. So I'm making a guest book. I wasn't sure what the difference was between char, varchar, and the different text types. I kept getting errors when I was created fields using the text types, so I switched them to char. Maybe that's because I was trying to define the max length of the field? The documentation isn't all that great.

Anyway, I've also read several things that say don't store the password in database. I want the users to be able to change their own entries, but only read other entries (with the exception of e-mail addresses). Basically the same as this forum works.

Also, to contect to the database, I have to put my master password for my web hosting account. What's to stop someone from figuring out my password and having at it with my account? The password will need to be in the connection string to the database. What is it that I'm not understanding here?

Here's how I set up the table sans password. Is this how it should be?

get yourself this utility for handling mysql db's

it makes like soooo much easier.

varchar is like a variable length string; it's length will be from 1 to the length you specify depending on the length of the string it stores

char is fixed length; it will always be the length you specify when defining the table regardless of contents. Usually it is best to stick with varchar

The max of both is ~255...if you need to store stuff longer, then use Text which can be upto 2 billion characters or something crazy like that

Can I upload that to where my site is hosted?

yes...just sling it in a dir and .htaccess the dir to stop others using it.

because it doesn't work that way. unless you just gave it to someone, nobody will get it. the surfer can't see the php page itself but the rendered part of it. so they won't be able to see the connection to the database. do you see it on these forums? no that is because it is in the php script where you can't see it.

OK, this is what I've got going so far. Chris, that app looks pretty much what my web host already provides.

I realize this is really lame. I'm just happy that it works at all.
