I would advise against using intval if the sql data type is anything
greater and/or equal to "int unsigned".
PHP on 32 bit systems: intval can only handle values up to 2147483647.
sql unsigned int can go up to |4294967295 and bigints even higher....
This could cause serious problems ...

$request_id = $_GET['id']; <--- I suppose this would be an int. True?
If so then add:
<?php
$request_id = intval($_GET['id']);
?>

Even better:
<?php
$request_id = $_GET['id'];
$current_user = substr($_SERVER['AUTH_USER'], 13);
$lock_query = "SELECT id, locked_by_user FROM locked_payments WHERE id =
'$request_id'";
$lock_result = mssql_query($lock_query) or
die(mssql_get_last_message());
$lock_row = mssql_fetch_array($lock_result);
if (empty($lock_row)) {
$lock_id = $lock_row['id'];
$lock_user = $lock_row['locked_by_user'];

mssql_query($set_lock) or die ("Query failed: <br

}
?>

Okay, gotcha!
I changed it to this and it works:
<?php
$request_id = $_GET['id'];
$current_user = substr($_SERVER['AUTH_USER'], 13);
$lock_query = "SELECT id, locked_by_user FROM locked_payments WHERE
id =
'$request_id'";
$lock_result = mssql_query($lock_query) or
die(mssql_get_last_message());
$lock_row = mssql_fetch_array($lock_result);
$lock_id = $lock_row['id'];
$lock_user = $lock_row['locked_by_user'];
if (empty($lock_row)) {
$set_lock = "INSERT into locked_payments (
id,
locked_by_user)
VALUES
('$request_id',
'$current_user')";
mssql_query($set_lock) or die ("Query failed: <br
/>".mssql_get_last_message());
}
?>
Thanks! :)

I think the $lock_result is just a resource #id you haven't fetched

Ah, what a lovely case of the Friday morning brain farts!
I have a query that selects some data from a table based on the
current
ID
selected.
If the query does not return any results, I want it to continue to
another
query that will insert a record into the table.
Below is what I have...but it will not insert anything if the first
query
does not find a match.
<?php
$request_id = $_GET['id'];
$current_user = substr($_SERVER['AUTH_USER'], 13);
$lock_query = "SELECT id, locked_by_user FROM locked_payments
WHERE id =
'$request_id'";
$lock_result = mssql_query($lock_query) or
die(mssql_get_last_message());
if (empty($lock_result)) {
$set_lock = "INSERT into locked_payments (
id,
locked_by_user)
VALUES
('$request_id',
'$current_user')";
mssql_query($set_lock) or die ("Insert failed: <br
/>".mssql_get_last_message());
}
?>
Any ideas on what I'm doing wrong? My guess is that
(empty($lock_result))
is probably not the correct way to check if an array is empty?
