FTP user. I upload some files. I create a database called
testOfSetupScri pt and then I create a database user named setup.
I write some PHP code which should, I think, be able to to auto create
the tables.
The SQL looks like this:
$str4 = <<<EOD
CREATE TABLE whatBelongsToWh at (
id int(11) NOT NULL auto_increment,
what int(11) NOT NULL default '0',
belongsToWhichP age int(11) NOT NULL default '0',
type varchar(255) NOT NULL default '',
belongsToWhichW ebsite varchar(255) NOT NULL default '',
PRIMARY KEY (id)
) TYPE=MyISAM;
EOD;
global $db;
$formInputs = $GLOBALS["formInputs "];
if (is_object($db) ) {
if (is_array($form Inputs)) {
extract($formIn puts);
$query = "SHOW TABLES FROM $dbName";
$result = $db->query($query );
$num = mysql_num_rows( $result);
// 11-23-04 - this code runs every time the pages loads. Obviously
we don't want to
// run this code if the tables already exist. So we check for tables
first.
if ($num == 0) {
$db->query($str1) ;
$db->query($str2) ;
$db->query($str3) ;
$db->query($str4) ;
$query = "SHOW TABLES FROM $dbName";
$result = $db->query($query );
$num = mysql_num_rows( $result);
if ($num == 4) {
echo "<p>The 4 parts of the database have been successfully
created</p>";
} else {
$errmsg = 'Query error: ' . mysql_error();
echo "<p>Awful sorry, there is a problem. The database should
have 4 tables but only has '$num'. $errmsg ";
}
} else {
if ($num < 4) {
echo "<p>The 4 parts of the database have been successfully
created</p>";
} else {
$errmsg = 'Query error: ' . mysql_error();
echo "<p>Awful sorry, there is a problem. The database should
have 4 tables but only has $num. $errmsg</p>";
}
}
}
} else {
echo "<p>Awful sorry, but the software expects a database object that
will allow us to connect to the database, but we don't seem able to
find or create the database object. Please make sure that the file
McDatastoreConn ectorMySql.php was uploaded and is in the 'neededFiles'
folder.</p>";
}
}
I'm only showing one of the SQL statements for simplicity.
But I get these warnings:
Warning: Supplied argument is not a valid MySQL-Link resource in
/home/httpd/vhosts/publicdomainsof tware.org/httpdocs/setup/neededFiles/McDatastoreConn ectorMySql.php
on line 349
Here is the method that is being flagged:
/*
error function
==============
terminates script execution with a message
*/
function error() {
die('('.mysql_e rrno($this->pp_linkid).' )
'.mysql_error($ this->pp_linkid));
}
Also I get this:
Warning: Supplied argument is not a valid MySQL result resource in
/home/httpd/vhosts/publicdomainsof tware.org/httpdocs/setup/neededFiles/createTheDataba seTables.php
on line 175
which points to the last line here:
$query = "SHOW TABLES FROM $dbName";
$result = $db->query($query );
$num = mysql_num_rows( $result);
I'm using this method to connect to the database. How do I trouble
shoot what the problem is?
