I'm going to make it write to a database rather than text file after searching google and coming accross common problems with text files. I've now just got to figure out how to mark the message as read in the database so it does not re-appear next time the user clicks update. I'm going to build a function that will put the message in the correct table using an if clause, is that the best method?

Happy new year folks! The titlemight make this seem like an easy to answer question However here's the complicated bit (well for me anyway). In my text file that is written to by the users in a chatroom it

looks

like this:

nickname||color||what the user is saying||user how can i make it so that if they have a private message when they

press update it pulls the message from the text file and displays it in the

frame

but also deletes the text?

You should be using a database for this, it makes things so much easier. That being said, here's one way to go about the text file version: Open the file, read through it line by line. As you read it, push the lines into an array. If you find a private message for the user, store that in a

variable,

and do not push it into the array. Finish reading the file. If there's a private message, you've got it in a variable, and you

can

overwrite the private message file with the array you've stored,

which

is all of the current private messages minus the one you're about to display. Please note, this does not scale at all, especially in the

fast-paced

world of chat rooms. You will likely end up with file locking problems if you proceed with the flat-file method.

Also, how can i make it so that if in a drop down menu they select

the

word "everybody" it goes to a file called messages.txt and if they

select

"user" or "user2" or "user3" from the list it writes to private.txt is

this

at all possible? user and user2 etc arent hardcoded it's pulling the

names

from a list of online users.

Are you talking about appending messages to a text file? In that case, you can have the dropdown submit with the message, and in the PHP code have a case for 'everybody' where it writes to

messages.txt,

and if it's not 'everybody', write it to private.txt with the

username

that was selected from the dropdown as part of the row. Does that answer your question? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
