How can I populate a form field with the content from a column in a table for later use in filling a main table in PHP?

To populate a form field with the content from a column in a table for later use in filling a main table in PHP, you can retrieve the data from the database using SQL queries and then populate the form field with the fetched data. You can use PHP to connect to the database, execute the query, fetch the data, and then display it in the form field. 

<?php
// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Retrieve data from the column in the table
$sql = "SELECT column_name FROM table_name";
$result = $conn->query($sql);

// Populate the form field with the fetched data
echo '<select name="column_name">';
while($row = $result->fetch_assoc()) {
    echo '<option value="' . $row['column_name'] . '">' . $row['column_name'] . '</option>';
}
echo '</select>';

// Close the database connection
$conn->close();
?>
