Displaying * in a table

i have 2 tables, users & tv shows. My users table holds user_id, username, displayname, password and my tv shows table holds, tv_id, user_id FK, showname and seasons.

My main index page displays all the results from the tvshows table and you can click on each individual result and it will take you to another page.

On my tvshows.php at the top of the page i want to display the name of the person who is assigned to that result in the tvshows table.

On my index.php:

Thank you!

This only displays the id of the person who created but i would like it to display the displayname. If i change user_id to displayname it won't work because its on a different table

Answer 1

You need to select from both tables using a JOIN. Just a quick example:

SELECT tvshows.user_id, users.displayname FROM tvshows, users WHERE (tvshows.user_id = users.user_id) AND (tvshow_id = '$tvshow_id')
