為什麼我在'rent.php”中收到'致命錯誤：在布林值上呼叫成員函數execute()”？

"Fatal Error: Call to a member Function execute() on Boolean" in "rent.php"

In your rent.php file, you have an error that causes a "Fatal error: Call to a member function execute() on boolean" message when you try to submit the form. This error occurs because the $req->prepare() call is returning FALSE instead of a statement object.

Root Cause:

The main issue is that you have a typo in your SQL query: you have written "INSET" instead of "INSERT". This typo causes $req->prepare() to fail and return FALSE instead of a statement object.

Solution:

To fix the error, simply correct the typo in your SQL query:

$req = $conn->prepare('INSERT INTO renter (email, msg_text) VALUES(?, ?)');

Additional Notes:

• It's important to always check the return value of $conn->prepare() to ensure that it returns a statement object. If it returns FALSE, you can use the $conn->error property to get more information about the error.
• You can also use mysqli_error() to retrieve the error message associated with any MySQL error.
