PHP Help for Newbie
I am reading the book "PHP Essentials" an cannot get any of the code to work. For instance, I have a very simple MySQL database with a table that contains 9 fields of information about books. I am attempting to add records to the db via a form.
Here is part of the code I am using:
<?php
if ((!$isbn) || (!$title) || (!$price)) {
header("Location: http://myurl/admin_addrecord1.php");
exit;
}
$sql = "INSERT INTO MASTER_PRODUCTS VALUES (\"$isbn\", \"$title\",
\"$author\", \"$publisher\",\"$category\", \"$type\", \"$info_blurb\",
\"$page_num\", \"$price\")";
$connection = mysql_connect("localhost", "myusername", "mypassword") or die
("could not connect ot db");
$db = mysql_select_db("mydatabasename", $connection) or die
("could not select db");
$sql_result = mysql_query($sql, $connection) or die
("could not do query");
if (!$sql_result) {
echo "could not add record";
So, when I run the html form that calls this script, I get the error: could not do query
So, it looks like I am connecting to the db and selecting the db, but I can't query. Can anyone explain what might be causing this. I've tried a couple of other scripts from the book...some that seem really short and simple, but nothing is working.
Thanks!!!
