Property Details

`$tableName` public property #

The table name

public string, null $tableName = null

Method Details

`addForeignKeys()` public method #

Adds the foreign keys.

public void addForeignKeys ( )

`safeDown()` public method #

This method contains the logic to be executed when removing this migration.

This method differs from down() in that the DB logic implemented here will be enclosed within a DB transaction. Child classes may implement this method instead of down() if the DB logic needs to be within a transaction.

Note: Not all DBMS support transactions. And some DB queries cannot be put into a transaction. For some examples, please refer to implicit commit.

public boolean safeDown ( )

return	boolean	Return a false value to indicate the migration fails and should not proceed further. All other return values mean the migration succeeds.

`safeUp()` public method #

This method contains the logic to be executed when applying this migration.

This method differs from up() in that the DB logic implemented here will be enclosed within a DB transaction. Child classes may implement this method instead of up() if the DB logic needs to be within a transaction.

Note: Not all DBMS support transactions. And some DB queries cannot be put into a transaction. For some examples, please refer to implicit commit.

public boolean safeUp ( )

return	boolean	Return a false value to indicate the migration fails and should not proceed further. All other return values mean the migration succeeds.
