What are some common challenges faced when trying to delete multiple records using checkboxes in PHP and odbc functions?

When trying to delete multiple records using checkboxes in PHP and odbc functions, a common challenge is properly handling the form submission and processing the selected checkboxes to delete the corresponding records from the database. One way to solve this is to iterate through the selected checkboxes, retrieve their values, and execute individual delete queries for each selected record. 

<?php
// Check if form is submitted
if(isset($_POST['delete_records'])){
    
    // Connect to the database
    $conn = odbc_connect("DSN", "username", "password");
    
    // Iterate through selected checkboxes
    foreach($_POST['checkbox'] as $record_id){
        // Sanitize input
        $record_id = odbc_prepare($conn, $record_id);
        
        // Execute delete query for each selected record
        $query = "DELETE FROM table_name WHERE record_id = ?";
        $result = odbc_execute($query, array($record_id));
        
        if($result){
            echo "Record with ID $record_id deleted successfully.<br>";
        } else {
            echo "Error deleting record with ID $record_id.<br>";
        }
    }
    
    // Close database connection
    odbc_close($conn);
}
?>

<form method="post">
    <?php
    // Display checkboxes for each record
    $result = odbc_exec($conn, "SELECT * FROM table_name");
    while($row = odbc_fetch_array($result)){
        echo "<input type='checkbox' name='checkbox[]' value='" . $row['record_id'] . "'>" . $row['record_name'] . "<br>";
    }
    ?>
    <input type="submit" name="delete_records" value="Delete Selected Records">
</form>
