Hi! I'm trying to learn PHP but as proceed with tutorials I encounter more and more problems. and I'm not sure if they are arising from my mistakes because I just rewrite very simple tutorial excerisies.

I get this two errors when I load table1.php in my browser:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:\wamp\www\table1.php on line 11

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\wamp\www\table1.php on line 25

I have created those three FIles :

createmovie.php - when i load it in browser i get "Movie database successfully created!" so no problem seems to be here

//create the main database if it doesn't already exist
$create = mysql_query("CREATE DATABASE IF NOT EXISTS moviesite")
	or die(mysql_error());
	//make sure taht recently made databse is the active one
//create movie table
$movie = "CREATE TABLE movie (
	movie_id int(11) NOT NULL auto_increment,
	movie_name varchar(255) NOT NULL,
	movie_type tinyint(2) NOT NULL default 0,
	movie_year int(4) NOT NULL default 0,
	movie_leadactor int(11) NOT NULL default 0,

AND the last one


$link = mysql_connect("localhost", "bp5am", "bp5ampass")
	or die(mysql_error());
		or die(mysql_error());
$query = "SELECT movie_name, movie_director, movie_leadactor " .
"FROM movie";
$results = mysql_query($query, $link)
		or die(mysql_error());
$num_movies = mysql_num_rows($result);    //       <------------------LINE 11
<h2><center>Movie Review Database</center></h2>
<table width="70%" border="1" cellpadding="2" cellspacing="2" align="center"
<th>Year of release</th>

<th>Movie lead actor</th>
<th>Movie type</th>
$movie_details = '';
while($row = mysql_fetch_array($result)) {       //  <---------------------LINE 25
	$movie_name = $row['movie_name'];
	$movie_director = $row['movie_director'];
	$movie_leadacotr = $row['movie_leadactor'];
	$movie_details .=<<<EOD
$movie_detalis .<<<EOD
<td>Total : $num_movies Movies</td>


I'm using the newest relaese of wampserver 2.0 (Apache2.2.8 ; PHP 5.2.5 ; MySQL 5.0.51a)
Although Excersis in my book are made on Apache(2.0.50.)PHP(5.0.0)MySQL(4.0.20)
Thanks for any help

you have mispelled your $results to $result on line 11.Just add a s on the end of $result.

You missed off an 's' the variable you defined is $results but you keep calling $result, change it to $results or change the defined variable to $result.

$result[B]s[/B] = mysql_query($query, $link)
$num_movies = mysql_num_rows($result);

hope that makes sense,


Sorry, posted at the same time as ryan, at least now you're doubley as sure.
