Question

Kindly do have a look at below mentioned SQL:

$sql ="INSERT INTO
    demo_participant
    (name, meeting_id_id, password, user_view__url, key, contact_no, email)
    VALUES
    ('$part_name', (SELECT id FROM demo_meeting WHERE meetingID = '$mtngid'),
    '$attendee_password', '$join_url', $getit_part['data'], '$pr_mobile',
    '$pr_email')";

My problem is the above statement is working fine without key and its associated value $getit_part['data']

But whenever I am trying to store key value I am getting the error i.e:

Parse error: syntax error, unexpected ” (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in /opt/lampp/htdocs/UI/user/joinmeeting.php on line 86

And when I am storing the value of $getit_part['data'] in another variable like $key then I am getting:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘key,contact_no,email) VALUES(‘Rohitn’,(SELECT id FROM demo_meeting WHERE ‘ at line 1

I know I am doing some syntax error but unable to debug it.

key is a reserved word in MySQL. escape it with backticks

`key`

and you can’t combine select and values. Try

INSERT INTO demo_participant(name, 
                             meeting_id_id, 
                             password, 
                             user_view__url, 
                             `key`, 
                             contact_no,
                             email)
SELECT '$part_name', 
       id, 
       '$attendee_password',
       '$join_url',
       '$getit_part['data']',
       '$pr_mobile',
       '$pr_email'
FROM demo_meeting
WHERE meetingID = '$mtngid'
