php usage

[coop]

Hi all,

still finding my feet with php and the basic stuff. I have this code that connects to the database and creates a table then closes the connection. Is it right to then open the connection and populate the tables with infomation. If I try to fill the tables within the code that creates the tables the database is created but the table isn't.
I know this is a really basic question, but I'm using phpmyAdmin where I can see the database is created and the tables, but is it possible to see the information I inserted.

[CODE]

<?php
$dbhost ='localhost';
$dbusername ='root';
$dbpassword = 'root';
$dbname = 'first';
//connect to the mysql database server.
$link = mysql_connect($dbhost,$dbusername,$dbpassword);
if(!$link){
die("could bot connect:".mysql_error());
}else{
echo"connected to server <br>";
}
//create database
$database = $dbusername."_".$dbname;
$query  = mysql_query("CREATE DATABASE $database");
if(!$query){
die("could not create database:".mysql_error());
}else{
echo"database created <br>";
}
//create tables
mysql_select_db($database)or die("unable to select database".mysql_error());
$query="CREATE TABLE contacts
(id int(6) NOT NULL auto_increment,
first VARCHAR(15) NOT NULL,
last VARCHAR(15) NOT NULL,
email VARCHAR(30) NOT NULL,
web VARCHAR(30) NOT NULL,
PRIMARY KEY (id),
UNIQUE id (id),
KEY id_2 (id))";
mysql_query($query);
mysql_close();
?>
//
//
<?php
$link = mysql_connect($dbhost,$dbusername,$dbpassword);
if(!$link){
die("could bot connect:".mysql_error());
}else{
echo"connected to server <br>";
}
mysql_select_db($database)or die("unable to select database".mysql_error());
$query ="INSERT INTO contacts VALUES('John','Smith','[email protected]','http://www.somewhere.com')";
mysql_query($query);
mysql_close();
?>
[/CODE]

Your insert query is generating an error...change:

[code]mysql_query($query);[/code]

to

[code]mysql_query($query) or die(mysql_error());[/code]

to see what it is....

Look at your table creation, you have these fields: id first last email web.  Now look at your insert statement:

[code]INSERT INTO contacts VALUES('John','Smith','[email protected]','http://www.somewhere.com')[/code]

You have five columns in the table, but you are only inserting four.  Change your query to:

[code]INSERT INTO contacts VALUES('', 'John','Smith','[email protected]','http://www.somewhere.com')[/code]

or

[code]INSERT INTO contacts (first, last, email, web) VALUES ('John', 'Smith', '[email protected]', 'http://www.somewhere.com')[/code]
