How to Display Individual Tables in Dropdowns from SQL?

Go to solution Solved by NotionCommotion,

Recommended Posts

I have 5 dropdowns on a tab of a website. I have a database table in MS SQL Server. The table has all the data of 5 dropdowns with one of the fieldNames called Region_Name, say the Region_Names are A, B, C, D, and E. I have written codes to display a table and enabled row editing for one of the RegionNames. Now, I am wondering if I could modify the same codes to display associated table with row editing enabled using different queries when a dropdown is clicked. That could reduce the code repetition and improve the performance. But I do not know how to achieve this. Could anyone please give me some hints? I am using PHP PDO to connect to the database.

Not sure I understand your question, so forgive me if you already know this.


Every time the browser makes a request to the server, it should include the region name in the URL (maybe use a default region name if none provided, and be sure to use isset() or something to make sure it exists). You then get the data based on the region name, pass it to a template, and display it.

$stmt = $conn->prepare('SELECT x,y,z FROM yourTable WHERE Region_Name=:Region_Name');
