How to insert data which does not have specific sequence? - mysql

Question

My array print_r is :
Array
(
[email] => xxx#cs.caddmu.edu
[attempt] => 0
[timestamp] => 1369676665
[smtp-id] => <1369676650.51a39b6a76cec#www.openaccesspub.org>
[response] => 451 4.2.0 Temporarily Grey listed. Try again in a couple of minutes
[category] => Invitation
[event] => deferred
)
Array
(
[email] => reidsdds#cs.cdsmu.edu
[timestamp] => 1369676845
[smtp-id] => <1369676650.51a39b6a76cec#www.openaccesspub.org>
[response] => 250 2.0.0 r4RHlOGH017661 Message accepted for delivery
[category] => Invitation
[event] => delivered
)
Array
(
[email] => jrai#openhh.com
[timestamp] => 1369678994
[smtp-id] => <1369678990.51a3a48e93428#ohhpb.org>
[category] => Reviewers
[event] => processed
)
Array
(
[email] => sss#lusst.fi
[timestamp] => 1369678997
[smtp-id] => <1369678990.51a3a48e93428#oub.org>
[response] => 250 2.0.0 Ok: queued as 02C103F0454
[category] => Revie
[event] => delivered
)
And the tables have these rows :
event_id, event, email, category, timestamp, response, attempt, url, status, reason, type, action, m_id .
I'm trying to insert in mysql table with this :-
foreach ($temp_array as $key => $poke)
{
mysql_query ("INSERT INTO temp_array (email,timestamp,category,event,response,attempt,reason,o_id,operator,action,...)VALUES ('$poke[email]','$poke[timestamp]','$poke[category]','$poke[event]',.... )" );
}
But i'm getting error " Undefined index: category in
C:\xampp\htdocs\eembeta\array_temp.php on line 34
How to insert data which does not have specific sequence?

Answer 1

This is not about sequence, but $poke['category'] does not exist in that array (element to insert). Be sure that all array fields you want to use are initialised:
$poke['category'] = $poke['category'] ? $poke['category'] : '';
That code means: Is that field set? yes: use it. no: use empty string.
That way $poke['category'] is known, so you get no error.
Btw, you can replace '' by 0, null or whatever you need.

Answer 2

Before using the data inside your query, sanatize it to avoid SQL Injections. To achieve this, consider using PDO.
Answering your question
For each key, create a temporary variable like:
$event = isset($_GET ['event']) ?$_GET ['event'] : null;
