    i have been trying to make the following php script work on fedora 5 os. but it does not show any data from the database. can any one please help. the code has been taken without any change from an online tutorial here.


    so i think it should be ok and the database has also been designed just as mentioned in the tutorial.


    mysql_select_db($database) or die( "Unable to select database");
    $query="SELECT * FROM contacts";



    "<b><center>Database Output</center></b><br><br>";

    while (
    $i $num) {


    "<b>$first $last</b><br>Phone: $phone<br>Mobile: $mobile<br>Fax: $fax<br>E-mail: $email<br>Web: $web<br><hr><br>";

    basically nothing is displayed. there are no error messages at all. i m going nuts. now a new problem has started when i type 'su' and enter password at the shell prompt and then type 'konqueror' some strange messages are being displayed. which are as follows:

    Link points to "/tmp/ksocket-root"
    Link points to "/tmp/kde-root"
    kbuildsycoca running.........

    and so on. can not really understand what is going on. all was fine just a few mins ago. help me please.thanks.

    Error messages in this sort of situation can be a b**** to find.

    Best places to look are in 1) The Apache logs (assuming you are using Apache) and 2) the MySQL logs.

    Post those and we may get some clue.

    However - MySQL is really weird with permissions, and this may be your problem. Don't forget that Apache/PHP is a different user compared to when you are using the mysql command line, so make sure that the Apache user has been allowed.

    hi guys,

    just finished a new installation of fedroa 5 and so far i have the following situation;

    root account with a password set up during the installation

    user account with a password set up during the installation

    STEP 1 : MySQL/services started:

    i have started the httpd (apache) and mysqld (mysql) services as well. plus many more services which i do not even understand but this just to make sure that all is fine.

    STEP 2 : Setting up accounts to access MySQL:

    As mentioned earlier i have two users root and another users with a password for the fedora 5 os but not password or account for them to access mysql. could you give me a few command that i can use to set up 2 separate accounts and separate passwords for both root and the other user. i need mysql comand to do so. please provide me with some.

    STEP 3 : Privileges to be steup:

    now i have not yet touched mysql at all. what i want is a command which allows all the users all the privelges in terms of mysql ie insert,update,delete and all possible. and a command that allows all the users to access all the databases fully ie insert,update,delete and all possible.

    STEP 4 : Create a database/table in MySQL:

    after doing the privileges with the help of a command that you would give me, i will then create a database from the command line in mysql. i m not used to phpmyadmin as of now so bear with me please.

    STEP 5 : Connect PHP and MySQL:

    I will ask you for a simple php script if you can provide me with one. the previous one i still could not figure out much as it contained a loop of some sort. what i want a script to be able to do is just select all fields fro a table. like select * from tablename. as simple as possible.

    What I want:

    so please guys let me know if i m taking the above steps in the right order or not. also provide me with the commands as mentioned above steps 1-5 and a simple infact very simple php script as described above. thanks. waiting for your help.

    is the mysql_close() in the correct place, I take that to mean you are closing the connection to the database before anything can be displayed to the screen?

    Hmm, just wondering whether re-installing the OS would make any difference at all.

    Ummm... Have you bothered going to the MySql site and reading their documentation? They have a ton of it that will explain how to work with just about any facet of a MySql database, and if you're planning on running a database you better have a thorough understanding of how MySql is set up. Depending on everyone else to hold your hand is a sure way to fail in the open source world. Pretty soon people will just tell you to rtfm.... I know I have that tendency when someone says they are just waiting for someone else to do the work for them....
