Well the concept is very simple. It requires a couple steps. First you need to run a query to get all the people in the db and their unique id. From that list you output their name and link pointing to your update form page with a $_GET var like admin-id=$row[‘id’] ($row[‘id’] being from the first query). Then on the update page you grab the $_GET[‘admin-id’] and put it in a hidden field of the form to submit along with the other fields, you will then use that posted hidden fields value to do a WHERE clause in the update query. Make you form and fields you want, post them and grab their values and validate them as needed. Then run a update query using the hidden fields value in the WHERE clause like WHERE id
= $_POST[‘admin-id’] LIMIT 1. I always use LIMIT 1 when testing or in important situations where a single mistake can mean a huge problem for many people. The limit makes it so not matter what the result only one row will be effected in case you have the code wrong.
Beyond that I don’t think anyone will code this for you so you should watch some tutorials on yourtube, there are plenty of them.
