SQL not updating and inserting data to database - php

Question

I have ajax which takes data (id, companyName, owed, oldRem) from a table in categorylist.php which is used in remit.php. Below is my ajax code categorylist.php which gets data from table row and it works well.
<script>
function payCompany(id, companyName, owed, oldRemit){
swal("Enter Amount:", {
title: companyName,
buttons: true,
closeModal: true,
content: "input",
})
.then((amount) => {
if (amount === "") {
swal("Oops!! You need to enter value.");
return false
}else{
$.ajax({
type: 'POST',
url: 'remit.php',
data:{
rid: id,
pay: amount,
company_Name: companyName,
old_Remit: oldRemit,
debt_owed: owed,
<?php
echo ' currentDate : "'.$savedate.'",'
?>
},
success: function(data){
swal(`Paid: ${amount} to ${companyName}`);
},
error: function(data){
swal(`Error remitting: ${amount} to ${companyName}`);
}
});
}
});
}
</script>
my code in remit.php. I couldn't confirm if the code is passed to remit.php from ajax. there was no error displayed when it was run.
<?php
#remit.php
/*
If you are using sessions you need to start a session!
*/
error_reporting( E_ALL );
session_start();
if( empty( $_SESSION['useremail'] ) OR empty( $_SESSION['role'] ) OR $_SESSION['role']=="Admin" ){
exit( header('Location: index.php') );
}
/*
Check that all fields that are required in the SQL have been submitted
*/
if( isset(
$_POST['rid'],
$_POST['pay'],
$_POST['currentDate'],
$_POST['compnyName'],
$_POST['old_remit'],
$_POST['debt_owed']
) ){
try{
include_once 'connectdb.php';
/*
When inserting, updating multiple tables there is some sense in using a transaction
so that if one part fails the db is not littered with orphan records
*/
$pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$pdo->beginTransaction();
$remitID = $_POST['rid'];
$new_remit = (double)$_POST['pay'];
$company = $_POST['compny_Name'];
$old_rem = (double)$_POST['old_remit'];
$total_debt = (double)$_POST['debt_owed'];
$current_date = $_POST['currentDate'];
$paid = $new_remit + $old_rem;
$currentDebt = $total_debt - $paid;
/*
The SQL command should use placeholders rather than embedded variables - the names are arbitrary
*/
$sql='INSERT INTO `tbl_category_remits` ( `payment_date`, `category`, `remitted` )
VALUES
( :pay_date, :comp, :remit )';
$stmt=$pdo->prepare( $sql );
$args=array(
':pay_date' => $current_date,
':comp' => $company,
':remit' => $new_remit
);
if( !$stmt->execute( $args ) )echo 'stmt#1 failed';
$sql='UPDATE `tbl_category` SET `remitted` =:payment , `debt` =:current_debt WHERE `catid`=:rid';
$stmt=$pdo->prepare( $sql );
$args=array(
':current_debt' => $currentDebt,
':payment' => $paid,
':rid' => $remitID
);
if( !$stmt->execute( $args ) )echo 'stmt#2 failed';
/*
If it all went well, commit these statements to the db
*/
if( !$pdo->commit() )echo 'commit failed';
}catch( PDOException $e ){
/*
Any problems, rollback the transaction and report issues -
not necessarily with the full `getMessage()` ~ perhaps just
'Error!' etc
*/
$pdo->rollBack();
echo $e->getMessage();
}
}else{
echo $e->getMessage();
}
?>
On the above code, I have an insert statement as well as update statements, both to different tables as shown below:
Please, what's wrong with my code? It doesn't seem to update and insert into the database. Please, I need help with this code!!
