First, i have use aes_encrypt
to encrypt the password
Then i have use aes_decrypt
to decrypt the password
The issue is when i try to echo out the data in a table using <?php echo $row['pass'];?>
, there'll be an error
"Undefined index: pass in"
SQL insert
insert into username (userName,pass) values('$userName', aes_encrypt('$pass','k'))
SQL select
SELECT UserNameID,userName,aes_decrypt(pass,'k') from username
What went wrong?
Don't you need to use an alias here?
SELECT aes_decrypt(pass, 'k') AS pass_decrypted FROM ...
And then access it with
echo $row['pass_decrypted'];
In your result set is the password column named as used function. All you need is to set an alias of that column such as: aes_decrypt(pass,'k') as 'pass'
:
SELECT UserNameID, userName, aes_decrypt(pass,'k') as pass FROM username
Your PHP code expect the column 'pass' in result set..
