Problem solved: Apparently, I did not check the structure of my table (ex. data types) that is why the data is not visible in mysql.问题已解决：显然，我没有检查表的结构（例如数据类型），这就是为什么数据在 mysql 中不可见的原因。

You have given wrong file name in forms action on index.php您在 forms 对 index.php 的操作中给出了错误的文件名
You have to write action="createdata.php" in form on index.php您必须在 index.php 上的表单中写入 action="createdata.php"

Form action should be like this:表单动作应该是这样的：
form action = "createdata.php" method="POST"表单动作=“createdata.php”方法=“POST”
Your query should be like this:您的查询应该是这样的：
$queryCreate = "INSERT INTO supplierinfo (Supplier_Name, Supplier_Contact, Supplier_StreetNo, Supplier_Province, Supplier_PostalCode, Supplier_Country) VALUES ('$Supplier_name', '$Supplier_Contact', '$Supplier_StreetNo', '$Supplier_Prov', '$Supplier_PostalCode', '$Supplier_Country')"; $queryCreate = "插入供应商信息（Supplier_Name，Supplier_Contact，Supplier_StreetNo，Supplier_Province，Supplier_PostalCode，Supplier_Country）值（'$Supplier_name'，'$Supplier_Contact'，'$Supplier_StreetNo'，'$Supplier_Prov'，'$Supplier_PostalCode'，'$Supplier_Country ')";

For your query为您查询
$queryCreate = "INSERT INTO supplierinfo (`Supplier_Name`, `Supplier_Contact`, `Supplier_StreetNo`, `Supplier_Province`, `Supplier_PostalCode`, `Supplier_Country`) VALUES ('$Supplier_name', '$Supplier_Contact', '$Supplier_StreetNo', '$Supplier_Prov', '$Supplier_PostalCode', '$Supplier_ountry')";
$sqlCreate = mysqli_query($connection, $queryCreate);
You only assigned mysqli_query($connection, $queryCreate) to a PHP variable, but you didnt execute it.您仅将 mysqli_query($connection, $queryCreate) 分配给 PHP 变量，但您没有执行它。
Try this尝试这个
if(mysqli_query($connection, $queryCreate)){
echo '<script>alert("Successfully created!")</script>';
}
