Insert in database with wpdb in PHP - php

Question

I try to make a function to insert more fields in database.
I find an example, but maybe more parameters is deprecated...or i have an error.
Here is my code:
private function _setUserPersonalDetails($blog_id, $personal_data, $operation = 'insert') {
global $wpdb;
// Strip any html tags from the about and address fields.
$tmp = array();
foreach ($personal_data as $key => $val) {
if (($key === 'about') || ($key === 'address')) {
$tmp[$key] = strip_tags($val);
}
else {
$tmp[$key] = $val;
}
}
$personal_data = $tmp;
if ($operation == 'insert') {
// Save personal data
$encoded_data = json_encode($personal_data);
$type = 'personal_data';
$q = $wpdb->prepare('INSERT INTO wp0_users_conta_data (blog_id, type, data) VALUES (%d, %s, %s)', $blog_id, $type, $encoded_data);
$wpdb->query($q);
}
if ($operation == 'update') {
// Update personal data
$encoded_data = json_encode($personal_data);
$type = 'personal_data';
$q = $wpdb->prepare('UPDATE wp0_users_conta_data set data=%s where blog_id=%d and type=%s', $encoded_data, $blog_id, $type);
$wpdb->query($q);
}
}
}
I spent more one week to solve the problem, but i don't find any solutions. I appreciate any helps. Thank you!
