PHP Code:

<?php
    include "logindb.php";
    
    $sql_table = "demo";
     
    $sql = "INSERT into demo (fname, lname, email, sadrs, city, state, zip, phone, demo) VALUES('$fname', '$lname', '$email', '$sadrs', '$city', '$state', $zip', '$phone', '$demo')";
?>

I am real n00b when it comes to inserting info into the database. That code doesn't seem to put anything in the database. I have a table called demo, and everything in logindb.php is correct. I have all the fields in the databse correct, so I would guess that something is wrong with the code.

Are you executing the query anywhere? All I see above is an include and two variables. Nothing that would execute the mysql query. In other words, are you using this function anywhere...

PHP Code:

mysql_query($sql) 


nope, I added it though, I dont if I did it correctly, but it doesn't seem to give me an error, but it still doesn't insert the info to the database:

PHP Code:

<?php
    include "logindb.php";
    
    $sql_table = "demo";
     
    mysql_query($sql) == "INSERT into demo ('', 'fname', 'lname', 'email', 'sadrs', 'city', 'state', 'zip', 'phone', 'demo') VALUES('', '$fname', '$lname', '$email', '$sadrs', '$city', '$state', $zip', '$phone', '$demo')";
?>

my fields within my table demo in order is:
id int(11)
fname vachar(30)
lname vachar(30)
email vachar(50)
sadrs vachar(50)
city vachar(15)
state vachar(15)
zip int(5)
phone int(10)
demo vachar(30)

mysql_query() is a function call, and you need to get your query string in between the brackets - this is passing a parameter to the function.

In your first attempt, you never called the function, in the second try, you have changed things around so that $sql is never set. You need to rewrite it as you had in the first example, and just add the line that cptnwinky gave you:

PHP Code:

<?php
    include "logindb.php";
    
    $sql_table = "demo";
    
    //This sets your variable
    $sql = "INSERT into demo (fname, lname, email, sadrs, city, state, zip, phone, demo) VALUES('$fname', '$lname', '$email', '$sadrs', '$city', '$state', $zip', '$phone', '$demo')";

    //This calls the function, using the variable we set above
    mysql_query($sql);
?>

Make sense?
