    2. COi am sorry i am new to asking basically if you remove the comments for the add function in index.php nothing will work, but because i commented out the add function the delete is working by hiding the record, but it is not being removed from the database and when i refresh i see all the records again.. as for add i want to do it dynamically and it is not working at all. but with refreshing it adds them successfully to the database.

    3. COLooks like your not passing in any data to your delete.php, in your delete.php you are checking for if(isset($_GET['id'])) but in your ajax you are not passing in any data string for that id,

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
