HTML Form: Select-Option to insert data into MySQL phpmyadmin database - php

Question

I have a php file named "add_report" with a form inside it. All my inputs are running, i can input data into my database, but everytime I use the select-option. my database accepts it as null. Why is that?
This is my form "add_report.php"
<div class="wrapper">
<form action="add_report_backend.php" method="post">
<input type="hidden" name="id">
<label>Agency: </label> <input class="input1" type="text" name="agency" value="CAAP" required readonly><br>
<label>File Name: </label> <input class="input2" type="text" name="filename" placeholder="file.pdf/xlsx/xls/docx" required autofocus><br>
<label>File Type: </label> <select name="myselectbox">
<option name="myoption1" value="myoption1">pdf</option>
<option name="myoption2" value="myoption2">excel</option>
<option name="myoption3" value="myoption3">word</option>
</select><br>
<label>Date: </label> <input class="input4" type="Date" name="date" required><br>
<input class="submit-btn" type="submit" name="insert" value="Save">
</form>
</div>
And this another php file "add_report_backend.php"
<?php
if(isset($_POST['insert']))
{
try {
$pdoConnect = new PDO("mysql:host=localhost;dbname=annualdb","root","");
$pdoConnect->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $exc) {
echo $exc->getMessage();
exit();
}
$id = $_POST['id'];
$Agency = $_POST['agency'];
$FName = $_POST['filename'];
$FType = $_POST['filetype'];
$Date = $_POST['date'];
$pdoQuery = "INSERT INTO `company_report`(`agency`, `filename`, `filetype`, `date`) VALUES (:Agency,:FName,:FType,:Date)";
$pdoResult = $pdoConnect->prepare($pdoQuery);
$pdoExec = $pdoResult->execute(array(":Agency"=>$Agency,":FName"=>$FName,":FType"=>$FType, ":Date"=>$Date));
if($pdoExec)
{
$pdoQuery = 'SELECT * FROM company_report';
$pdoResult = $pdoConnect->prepare($pdoQuery);
$pdoResult->execute();
while ($row = $pdoResult->fetch()){
echo $row['id'] . " | " .$row['agency'] . " | " . $row['filename'] . " | " . $row['filetype'] . " | " . $row['date'];
}
header("Location: ../agencies/company.php");
exit;
} else {
echo 'Data Not Inserted';
}
}
$pdoConnect = null;
?>

Answer 1

The HTML name attribute and the $_POST name should be the same.
You need to change
$FType = $_POST['filetype'];
by
$FType = $_POST['myselectbox'];

Answer 2

Change $FType = $_POST['filetype']; to $FType = $_POST['myselectbox'];
