Connection

jacobelias

Hello,

I am very new to PHP and Mysql.

How can I connect to database from PHP?

Thanks

A way...

$connect = mysql_connect($db_addr,$db_user,$db_pass) or die(mysql_error());
if (!($connect)) // If no connect, error and exit().
{
echo("<p>Unable to connect. Please try again later.</p>");
exit();
}
if (!(mysql_select_db($db_name))) // If no database, error and exit().
{
echo("<p>Unable to locate. Please try again later.</p>");
exit();
}

Cheers.

Hello Zmola,

I am attaching my php files in a file files.zip. I have tried giving my dbname,username and password, but in the browser i am getting
error like
Undefined variable: cmd in c:\program files\apache group\apache\htdocs\softc\startpage.php

Can you please help.

Thanks,

Jac

Perhaps try...

// Turn down error reporting at start of file
error_reporting (E_ALL ^ E_NOTICE);

// Check to see if $cmd variable isset in startpage.php
if(!(isset($cmd)) || strlen($cmd)==0 || $cmd=="1")
 {
 	$file = "login.php";
 }

Cheers.

Hello,

I included both
// Turn down error reporting at start of file
error_reporting (E_ALL ^ E_NOTICE);

// Check to see if $cmd variable isset in startpage.php
if(!(isset($cmd)) || strlen($cmd)==0 || $cmd=="1")
{
$file = "login.php";
}

However it still giving

Undefined variable: cmd in c:\program files\apache group\apache\htdocs\softc\startpage.php on line 15

and

Notice: Undefined variable: alert in c:\program files\apache group\apache\htdocs\softc\login.php on line 112

Thanks,

Hi. Does the zip contain all the files for this script? The authorise.php file has, for example, calls to homepage.php?cmd=1 and to startpage.php?err=XYABC but login.php looks like it deals with $err whereas it seems startpage.php deals with $cmd.

Hello,

Is this error is because of any version? If I use the latest
version of PHP will it solve the problem?

you can not send header() output with PHP after a sigle bit has been sent to the browser, before ANYTHING header() has to be sent, otherwise it cant do anything
