Line 24 ends with a semicolon that shouldn't be there:
CODE if ('$login_user' === '$user' && '$login_pass' === '$password'); Side-note: http://www.htmlhelp.com/reference/wilbur/misc/comment.html says: QUOTE Note that an "empty" comment tag, with just "--" characters, should always have a multiple of four "-" characters to be legal. |

Now the only thing that comes up is the second page that says "incorrect username or password" even if it's right

CODE $login_user = mysql_query("SELECT username FROM user"); $login_pass = mysql_query("SELECT password FROM user"); The above returns the entire username and password columns in the DB table. You also need to loop through the column rows until you find one that matches the submitted form data. CODE if ('$login_user' === '$user' && '$login_pass' === '$password'); This post has been edited by Christian J: May 26 2012, 01:07 PM |

The above returns the entire username and password columns in the DB table. You also need to loop through the column rows until you find one that matches the submitted form data. I'm not very experienced with databases, but if the DB table contains lots of rows I guess it's more efficient to search for the submitted form data already in the SQL query? In that case you should sanitize the form data to prevent SQL injections. See also http://php.net/manual/en/function.mysql-re...cape-string.php |

What you get from a mysql_query is a resource handle, not a variable name. A resource handle id's the particular data you asked for in the SELECT statement. Now you have to look for the particular data pair of interest and do something with it.
So first: connect to the database, Second: perform a query to get a resource id. Third: use the resource id to translate the dataset to a form you can use. Fourth: examine the dataset, entry by entry, to find the particular data you're looking for. If you find it, do one thing, If you don't find it, do another thing. BTW, there is mysql and there is mysqli. Which one do you want to use? |

What's the difference between MySQL and mysqli?

mysqli and PDO (Php Data Objects) are the newer object oriented PHP APIs to access mysql databases.
