Form Submission
Hi, everybody! I am just starting with PHP, and I know very little. The book that I have goes over how to submit info from a form via EMail, but not into a flatfile database. Thats all I want right now...it goes over how to submit into a MySQL database, but I dont have one. I cant seem to find it on the internet either. Could you guys help me? Thanks.

Hi Kyle,
Here are some links that might help you:
- http://www.php.net/manual/en/function.fopen.php (to open/create a file)
- http://www.php.net/manual/en/function.fwrite.php (to write to a file)
You will find all the information you need on those two pages. Just read through them and use common sence (open a file, then write to it
).
Good luck.

ok so i would do something like:
$fp = fopen ("/home/restricted/reportbug.txt", "w");and also, how would i parse the contents of the form (written in HTML) to translate into variables or whatnot?

It's very simple. In your HTML form, if you name a text box for example "name", then after you submit, the value of the text box "name" will be in the variable $name.
Here's a sample script..
<?php$fp = fopen (\"/home/restricted/reportbug.txt\", \"w\"); //Open the file
fwrite($fp, \"Name...: $name\n\"); //Write a line to the file. \n = new line
fclose ($fp); //close the file
?>
Add as many fwrite() you want and don't forget \n means new line. You could write two or more lines in one fwrite(). For example:
fwrite($fp, "Name...: $name\nAddress....: $address\nCity...: $city\n");
I hope this helps.

What is included in php-bin/phpinclude.inc??
Also, this will write to the DB even if it isn't valid... move the last bracket around the form addition part...
i'll work in fixing this, I hope

Kyle,
Why don't you try things out first or search php.net's documentation and then if you still have problems, we will help you out. I really hate people that expect you to do the work for them.

Kyle, the code you have will work for writting the info into a flat-file database (a simple ASCII file).

The thing is, if you had tried it out yourself first, you would have known that $REMOTE_ADDR contains the visitors IP address. You could have also tried searching on PHP.net for "env" which would have resulted in you finding this page (which explains everything you need to know about env). I don't mind helping people out, but I hate it when people want you to do the job for them (which to me it seemed as what you were doing with your last question).

zollet...i know what environment variables are. i knew that $REMOTE_ADDR gets the IP Address, i was asking if that was the correct format...
Thanks, Mark.

Still, my point is that you did not try it out to see if it works or not before asking for our help.
Anyways, I didn't/don't want to start an argument.
