Common
aggregate#
limit#
Limits the number of records that are used when aggregating items
mshop/common/manager/aggregate/limit = 10000
- Default:
10000
- Type: integer - Number of records
- Since: 2021.04
As counting huge amount of records (several 10 000 records) takes a long time, the limit can cut down response times so the counts are available more quickly in the front-end and the server load is reduced.
Using a low limit can lead to incorrect numbers if the amount of found items is very high. Approximate item counts are normally not a problem but it can lead to the situation that visitors see that no items are available despite the fact that there would be at least one.
count#
ansi#
Counts the number of records matched by the given criteria in the database
mshop/common/manager/count/ansi =
- Type: string - SQL statement for counting items
- Since: 2023.10
Counts all records matched by the given criteria from the database. The records must be from one of the sites that are configured via the context item. If the current site is part of a tree of sites, the statement can count all records from the current site and the complete sub-tree of sites.
As the records can normally be limited by criteria from sub-managers, their tables must be joined in the SQL context. This is done by using the "internaldeps" property from the definition of the ID column of the sub-managers. These internal dependencies specify the JOIN between the tables and the used columns for joining. The ":joins" placeholder is then replaced by the JOIN strings from the sub-managers.
To limit the records matched, conditions can be added to the given criteria object. It can contain comparisons like column names that must match specific values which can be combined by AND, OR or NOT operators. The resulting string of SQL conditions replaces the ":cond" placeholder before the statement is sent to the database server.
Both, the strings for ":joins" and for ":cond" are the same as for the "search" SQL statement.
Contrary to the "search" statement, it doesn't return any records but instead the number of records that have been found. As counting thousands of records can be a long running task, the maximum number of counted records is limited for performance reasons.
The SQL statement should conform to the ANSI standard to be compatible with most relational database systems. This also includes using double quotes for table and column names.

decorators#
default#
Configures the list of decorators applied to all shop managers
mshop/common/manager/decorators/default = Array
(
[Depth] => Depth
[Lazy] => Lazy
)
- Default:
Array ( )
- Type: array - List of decorator names
- Since: 2014.03
Decorators extend the functionality of a class by adding new aspects (e.g. log what is currently done), executing the methods of the underlying class only in certain conditions (e.g. only for logged in users) or modify what is returned to the caller.
This option allows you to configure a list of decorator names that should be wrapped around the original instances of all created managers:
mshop/common/manager/decorators/default = array( 'decorator1', 'decorator2' )
This would wrap the decorators named "decorator1" and "decorator2" around all controller instances in that order. The decorator classes would be "\Aimeos\MShop\Common\Manager\Decorator\Decorator1" and "\Aimeos\MShop\Common\Manager\Decorator\Decorator2".
delete#
ansi#
mshop/common/manager/delete/ansi =
DELETE FROM ":table"
WHERE :cond AND "siteid" LIKE ?
- Default:
mshop/test/manager/delete
mysql#
mshop/common/manager/delete/mysql =
DELETE FROM ":table"
WHERE :cond AND "siteid" LIKE ?
- Default:
DELETE FROM ":table" WHERE :cond AND "siteid" LIKE ?
insert#
ansi#
Inserts a new record into the database table
mshop/common/manager/insert/ansi =
INSERT INTO ":table" (
:names
"mtime", "editor", "siteid", "ctime"
) VALUES (
:values
?, ?, ?, ?
)
- Default:
mshop/test/manager/insert
- Type: string - SQL statement for inserting records
- Since: 2023.10
Items with no ID yet (i.e. the ID is NULL) will be created in the database and the newly created ID retrieved afterwards using the "newid" SQL statement.
The SQL statement must be a string suitable for being used as prepared statement. It must include question marks for binding the values from the item to the statement before they are sent to the database server. The number of question marks must be the same as the number of columns listed in the INSERT statement. The order of the columns must correspond to the order in the save() method, so the correct values are bound to the columns.
The SQL statement should conform to the ANSI standard to be compatible with most relational database systems. This also includes using double quotes for table and column names.

mshop/common/manager/insert/mysql =
INSERT INTO ":table" (
:names
"mtime", "editor", "siteid", "ctime"

maxdepth#
Maximum level of recursion for retrieving referenced items
mshop/common/manager/maxdepth = 2
- Default:
2
- Type: int - Number of levels
- Since: 2019.04
Searching for items also fetches the associated items referenced in the list tables if the domain names are passed to the second parameter of e.g. the search() method. To avoid infinite recursion because two items reference each other, the maximum level must be limited.
The default setting (two levels) means that retrieving a product item with sub-products will retrieve the directly associated products but not the products referenced by the associated product for example.
newid#
ansi#
Retrieves the ID generated by the database when inserting a new record
mshop/common/manager/newid/ansi =
- Type: string - SQL statement for retrieving the last inserted record ID
- Since: 2023.10
As soon as a new record is inserted into the database table, the database server generates a new and unique identifier for that record. This ID can be used for retrieving, updating and deleting that specific record from the table again.
For MySQL:
SELECT LAST_INSERT_ID()
For PostgreSQL:
SELECT currval('seq_matt_id')
For SQL Server:
SELECT SCOPE_IDENTITY()
For Oracle:
SELECT "seq_matt_id".CURRVAL FROM DUAL
There's no way to retrive the new ID by a SQL statements that fits for most database servers as they implement their own specific way.

Retrieves the records matched by the given criteria in the database
mshop/common/manager/search/ansi =
SELECT :columns

WHERE :cond
GROUP BY :group
ORDER BY :order
OFFSET :start ROWS FETCH NEXT :size ROWS ONLY
- Type: string - SQL statement for searching items
- Since: 2023.10
Fetches the records matched by the given criteria from the database. The records must be from one of the sites that are configured via the context item. If the current site is part of a tree of sites, the SELECT statement can retrieve all records from the current site and the complete sub-tree of sites.
As the records can normally be limited by criteria from sub-managers, their tables must be joined in the SQL context. This is done by using the "internaldeps" property from the definition of the ID column of the sub-managers. These internal dependencies specify the JOIN between the tables and the used columns for joining. The ":joins" placeholder is then replaced by the JOIN strings from the sub-managers.
To limit the records matched, conditions can be added to the given criteria object. It can contain comparisons like column names that must match specific values which can be combined by AND, OR or NOT operators. The resulting string of SQL conditions replaces the ":cond" placeholder before the statement is sent to the database server.
If the records that are retrieved should be ordered by one or more columns, the generated string of column / sort direction pairs replaces the ":order" placeholder. Columns of sub-managers can also be used for ordering the result set but then no index can be used.
The number of returned records can be limited and can start at any number between the begining and the end of the result set. For that the ":size" and ":start" placeholders are replaced by the corresponding values from the criteria object. The default values are 0 for the start and 100 for the size value.
The SQL statement should conform to the ANSI standard to be compatible with most relational database systems. This also includes using double quotes for table and column names.

mshop/common/manager/update/ansi =
- Type: string - SQL statement for updating records
- Since: 2023.10
Items which already have an ID (i.e. the ID is not NULL) will be updated in the database.
The SQL statement must be a string suitable for being used as prepared statement. It must include question marks for binding the values from the item to the statement before they are sent to the database server.
