Question

Is there a way in MySQL and PHP to allow only the person performing an update to view information about a particular record?

For example, if one user loads the page they are presented with a record which must be updated, until that user finishes updating this record, any other user accessing this page should not be able to view this particular record.

Answer 1

You can either add a field named like locked where you set a status. Maybe you also add a field like lockedtime where you save a timestamp how long the lock is active. That depends on your needs.

There are also possibilities to do this native. Like

SELECT * FROM table WHERE primarykey = x FOR UPDATE;
