I've worked with this code all morning & it was working earlier but I've screwed it up somehow! This code is supposed to display a form in a browser, the user inserts the data then submits it & it gets written to a mysql database. At this time, EVERYTIME I go to the htttp://mysite/add.php it goes straight to google & I do not see my form to insert the text in the fields anymore...please help!

Get rid of the redirect to Google.  You have it set up so that if the PHP works properly, it goes to Google.  I don't think that's what you want.

Line 61:
header( "Location: http://www.google.com" );


That code automatically redirects you to google.

Also, be sure that is not your actual username and password for your db in that code... if so, you just posted that for all to see :-/

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

It's not the real UN & PW but thanks for checking that. I still can't get it to work, if I take the re-direct out I get a page can not be displayed & blank entry gets put in the mysql database.

I've narrowed it down to this simple code & it still will not insert the data into the mysql database.....what am I missing...I am very new to programming as you can see...
<html>

<?php
	$config["HOSTNAME"]		= "localhost";
	$config["USERNAME"]		= "root";
	$config["PASSWORD"] 	= "12ibtlalc25";
	$config["DBNAME"]      	= "psrflow";
	
	$dbconn = mysql_pconnect($config["HOSTNAME"], $config["USERNAME"], $config["PASSWORD"]) or  die(mysql_error());
	mysql_select_db($config["DBNAME"] , $dbconn);
?>

Where you have this

$strSQL = "INSERT INTO psrinfo
	( offender_fname, offender_lname, location )
	VALUES
	( '" . $offender_fname . "', '" . $offender_lname . "', '" . $location . "' )";

#	execute db insert
##########################
if (!mysql_query( $strSQL, $conn )){
	echo( "Unable to save data to database: <br/>" . mysql_error() . "<br/>" . $strSQL . "</span><br/>" );
}
else{
	header( "Location: http://www.google.com" );
}
?>

You are ALWAYS executing the query. What you need to do is ONLY execute it on someone pressing the submit button. Start by giving your submit button a name

<input name='submit' type="submit" value="Submit" />

Then detect it in the code

if ( isset( $_POST['submit'] == "Submit" ) {
......code here
}

then insert your SQL statement where I wrote .....code here in the fragment above


$strSQL = "INSERT INTO psrinfo
	( offender_fname, offender_lname, location )
	VALUES
	( '" . $offender_fname . "', '" . $offender_lname . "', '" . $location . "' )";

if ( isset( $_POST['submit'] == "Submit" ) {
   #	execute db insert
   ##########################
   if (!mysql_query( $strSQL, $conn )){
   	   echo( "Unable to save data to database: <br/>" . mysql_error() . "<br/>" . $strSQL . "</span><br/>" );
   }
}

Get rid of addslashes().  See the note here about that, "It's highly recommended to use DBMS specific escape function (e.g. mysqli_real_escape_string() for MySQL..."

I think hielo has got you on the right track.  Going forward, it is usually easiest to write and debug your code in tiny bits.  First make sure you can get the form input and print it out (learn about http://us2.php.net/manual/en/function.var-dump.php), then make sure you can write the data into the data base.  When each part of the app works, add the next layer.

You might also want to learn about version control with GitHub or SubVersion.  Then you won't lose your old copies of code that worked!
