How can improper naming conventions for form elements in PHP lead to errors when trying to insert data into a database?

Improper naming conventions for form elements in PHP can lead to errors when trying to insert data into a database because the names of the form elements need to match the column names in the database table. To solve this issue, ensure that the form element names correspond with the column names in the database table. 

// Example of correct naming conventions for form elements in PHP
<form action="insert_data.php" method="post">
    <input type="text" name="first_name">
    <input type="text" name="last_name">
    <input type="submit" value="Submit">
</form>

// insert_data.php
<?php
$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];

// Insert data into the database using correct naming conventions
$query = "INSERT INTO table_name (first_name, last_name) VALUES ('$first_name', '$last_name')";
// Execute the query
?>
