Query executed without errors but no data in database - php

Question

After executing the SQL file below to create the appropriate tables(which gets executed correctly without errors),
<?php
try {
require_once 'dbcon.php';
$sql_file = 'mysql.sql';
$contents = file_get_contents($sql_file);
$comment_patterns = array('/\/\*.*(\n)*.*(\*\/)?/',
'/\s*--.*\n/',
'/\s*#.*\n/',
);
$contents = preg_replace($comment_patterns, "\n", $contents);
$statements = explode(";\n", $contents);
$statements = preg_replace("/\s/", ' ', $statements);
foreach ($statements as $query) {
if(trim($query) != '') {
$db->query($query);
if ($db->errno) {
throw new Exception("Fail to load data in database (".$db->errno.")");
}
}
}
Running the following query right after the foreach gets executed successfully without errors and success message gets printed. However , no data gets inserted into the database.
$cql = "INSERT INTO config (logo,brand,provider,mail_type,url) VALUES(?,?,?,?,?)";
$cstmt = $db->prepare($cql);
$sch_logo = 'logo.png';
$sch_brand = 'brand.png';
$provider = 'other';
$mail_type = 'mail';
$cstmt->bind_param('sssss',$sch_logo,$sch_brand,$provider,$mail_type,$site_url);
$cstmt->execute();
if($cstmt->affected_rows === 1){
echo 'Identity verified. Thank you';
}
else{
throw new Exception("An error occurred Performing this operation.");
}
}
catch(Exception $e) {
error_log($e->getMessage());
echo ' <div class="text-warning">
<b>'.$e->getMessage().'</b> </div>';
exit();
}
?>
I have printed out $cstmt->error and $cstmt->errno and they all return 0 . which seems fine but don't why the data doesn't get inserted into the fields. Anything am missing or doing wrong?

Try this:
$cql = "INSERT INTO config (logo,brand,provider,mail_type,url) VALUES(?,?,?,?,?)";
$cstmt = $db->prepare($cql);
$sch_logo = 'logo.png';
$sch_brand = 'brand.png';
$provider = 'other';
$mail_type = 'mail';
$cstmt->bind_param('sssss',$sch_logo,$sch_brand,$provider,$mail_type,$site_url);
**if($cstmt->execute()){**
echo 'Identity verified. Thank you';
}
else{
throw new Exception("An error occurred Performing this operation.");
}
}
catch(Exception $e) {
error_log($e->getMessage());
echo ' <div class="text-warning">
<b>'.$e->getMessage().'</b> </div>';
exit();
}
