I have a little problem with my if(isset($_POST[\'submit\'])) code. What I want is some echos and a table to not appear when the script is open but I do want it

Answer 1

What you're checking

if(isset($_POST['submit']))

but there's no variable name called "submit". well i want you to understand why it doesn't works. lets imagine if you give your submit button name delete and check if(isset($_POST['delete'])) then it works in this code you didn't give any name to submit button and checking its exist or not with isset(); function so php didn't find any variable like "submit" so its not working now try this :
