我正在使用带有插入的自我发布表单，以及用于连接数据库的包含页面。当我在网站上运行该过程时，所有if / else语句都显示为true（表示该站点确认了该条目）。但是，当我检查我的phpMyAdmin数据库时，没有存储任何内容。我很困惑，因为网站确认输入的所有内容，但我的数据库不会填充。为了实验，已经注释掉了行和块。这是我的代码：
<?php
session_start();
if(isset ($_SESSION['uname']) == "true") //If this is a valid user allow access to this page
{
if(isset($_POST["submit"]))
{
//The form has been submitted and needs to be processed
include 'connectionAgain.php'; //connects to the database
//Validate the form data here!
//Get the name value pairs from the $_POST variable into PHP variables
//uses the same name/value pairs from the form
/*$event_id = $_POST[event_id];
$event_name = $_POST[event_name];
$event_description = $_POST[event_description];
$event_presenter = $_POST[event_presenter];
$event_date = $_POST[event_date];
$event_time = $_POST[event_time];*/
$sqlHardCode = "INSERT INTO nephilim42_341 . wdv341 (event_id, event_name, event_description, event_presenter, event_date, event_time) VALUES (?, ?, ?, ?, ?, ?);";
//Create the SQL command string
/*$sql = "INSERT INTO wdv341 (";
$sql .= "event_id, ";
$sql .= "event_name, ";
$sql .= "event_description, ";
$sql .= "event_presenter, ";
$sql .= "event_date, ";
$sql .= "event_time"; //Last column does NOT have a comma after it.
$sql .= ") VALUES (?,?,?,?,?,?)";*/ //? Are placeholders for variables
//Display the SQL command to see if it correctly formatted.
echo "<p>$sql</p>";
$query = $connection->prepare($sql); //Prepares the query statement
//Binds the parameters to the query.
//s = string: i = integer: b = blob: d = double: (DATATYPES)
$query->bind_param("ssssss",null, $event_name, $event_description, $event_presenter, $event_date, $event_time);
//Run the SQL prepared statements
if ( $query->execute() )
{
$sqlHardCode = "INSERT INTO nephilim42_341 . wdv341 (null, event_name, event_description, event_presenter, event_date, event_time) VALUES ( $event_name, $event_description, $event_presenter, $event_date, $event_time);";

$message = "<h1>Your record has been successfully added to the database.</h1>";
$message .= "<p>Please <a href='redirect.php'>view</a> your records.</p>";
}
else
{
$message = "<h1>You have encountered a problem.</h1>";
$message .= "<h2 style='color:red'>" . mysqli_error($link) . "</h2>"; //remove this for production purposes
}
$query->close();
$connection->close(); //closes the connection to the database once this page is complete.
}// ends if submit
else
{
header('location: redirect.php');
//Form has not been seen by the user. display the form
}
}//end Valid User True
else

//Invalid User attempting to access this page. Send person to Login Page
