Re: [PHP] Empty Array?

[marek]

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'];
$set_lock = "INSERT into locked_payments (
    id,
    locked_by_user)
    VALUES
     ('$request_id',
    '$current_user')";
mssql_query($set_lock) or die ("Query failed: <br
/>".mssql_get_last_message());
}
?>

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 any
data yet. True?

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?
