Before sending data I sctrictly check if all fields are filled correctly and then send that data to future processing. Using php script I'll check if web form button which was clicked is not null and then via established connection to mysql execute manipulation queries. Is using header function to redirect to itself is an optimal way to prevent Double Data Submission???</p> <p>Haven't you any ideas?</p> <p>In addition I'll include the code</p> <pre><code><?php include_once '../config.php';

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.
