5 * This should allow you to dump a series of data, so it could be restored later...
6 * The format will be an SQL file...
9 * php index.php Admin/Dump --table=Project --where="id=123"
10 * --dump-dir=/directory_to_put_sql+shell files
12 * outputs list of generated files.
15 * {DATE}.sql - the recreate sql including all dependancies, run with mysql DB -f < ....
16 * {DATE}.restore.sh - shell script to recreate files that where removed (excluding thumgs)
19 * {DATE}.copy.sh - shell script that backs up all the related files.
22 * {DATE}.delete.sql - the delete data sql.
23 * {DATE}.delete.sh - shell script to delete the files related to these records
26 * Basically it has to output all the records and their dependants. (parent and children)
28 * Then when deleting it deletes record + children..
31 * Each ouput is simple insert statement..
34 * TODO - handle Images table (or similar) where we use tablename=XXXX, tid=.... etc..
39 * DataObjects->archivePaths() - returns array ( sourcedirectory, remainder of path to dependant file )
40 * DataObjects->listThumbs() - returns array ( list of full path to thumbnail urls. )
