how to insert hidden data into HTML table and extract it later

[luceolsare]

Hi,

Hope somebody can help me because I am relatively new to PHP and I am currently unsure how to implement the following:

 

Let's assume I have a table like this id_number, name, data1, data2. When displayed on HTML page:

Column id_number should be hidden.

Column name is a link. When you click on this column then value stored in id_number should be used in a query to database. Result should be displayed below the link on the same page. When clicked again data should hide.

 

I have some idea how to toggle visibility with a simple javascript function. How do i populate the table with hidden data and then extract it later on?

 

Any help or suggestions are appreciated. Thanks.
