select

This object generates an SQL-select statement to select records from the database.

Some records are hidden or timed by start- and end-times. This is automatically added to the SQL-select by looking for "enablefields" in the $GLOBALS['TCA'].

Warning

Do not use GET or POST data like GPvar directly with this object! Avoid SQL injections! Don't trust any external data! Secure any unknown data, for example with intval.

Condensed form:

10 = CONTENT
10 {
   table =
   select {
      uidInList =
      pidInList =
      recursive =
      orderBy =
      groupBy =
      max =
      begin =

      join =
      leftjoin =
      rightjoin =
   }
}

uidInList

Property
uidInList
Data type
list of record_ids / stdWrap
Description

Comma-separated list of record uids from the according database table. For example when the select function works on the table tt_content, then this will be uids of tt_content records.

Note: this is a special keyword and replaced with the id of the current record.

Example
select.uidInList = 1,2,3
select.uidInList = this

pidInList

Property
pidInList
Data type
list of page_ids / stdWrap
Description

Comma-separated list of pids of the record. This will be page uids (pids). For example when the select function works on the table tt_content, then this will be pids of tt_content records, the parent pages of these records.

Pages in the list, which are not visible for the website user, are automatically removed from the list. Thereby no records from hidden, timed or access-protected pages will be selected! Nor will be records from recyclers. Exception: The hidden pages will be listed in preview mode.

Special keyword: this
Is replaced with the id of the current page.
Special keyword: root
Allows to select records from the root-page level (records with pid=0, e.g. useful for the table "sys_category" and others).
Special value: -1
Allows to select versioned records in workspaces directly.
Default
this
Example

Fetch related sys_category records stored in the MM intermediate table:

10 = CONTENT
10 {
   table = sys_category
   select {
      pidInList = root,-1
      selectFields = sys_category.*
      join = sys_category_record_mm ON sys_category_record_mm.uid_local = sys_category.uid
      where.data = field:_ORIG_uid // field:uid
      where.intval = 1
      where.wrap = sys_category_record_mm.uid_foreign=|
      orderBy = sys_category_record_mm.sorting_foreign
      languageField = 0 # disable translation handling of sys_category
   }
}

recursive

Property
recursive
Data type
integer / stdWrap
Description
Number of recursive levels for the pidInList.
Default
0

orderBy

Property
orderBy
Data type
SQL-orderBy / stdWrap
Description
ORDER BY clause without the words "ORDER BY".
Example
orderBy = sorting, title

groupBy

Property
groupBy
Data type
SQL-groupBy / stdWrap
Description
GROUP BY clause without the words "GROUP BY".
Example
groupBy = CType

max

Property
max
Data type
integer + Calc +"total" / stdWrap
Description

Max records

Special keyword: "total" is substituted with count(*).

begin

Property
begin
Data type
integer + Calc +"total" / stdWrap
Description

Begin with record number value.

Special keyword: total
Is substituted with count(*).

where

Property
where
Data type
SQL-where / stdWrap
Description
WHERE clause without the word "WHERE".
Example
where = (title LIKE '%SOMETHING%' AND NOT doktype)

languageField

Property
languageField
Data type
string / stdWrap
Description

By default all records that have language-relevant information in the TCA "ctrl"-section are translated on translated pages.

This can be disabled by setting languageField = 0.

includeRecordsWithoutDefaultTranslation

Property
includeRecordsWithoutDefaultTranslation
Data type
boolean / stdWrap
Description
If content language overlay is activated and the option languageField is not disabled, includeRecordsWithoutDefaultTranslation allows to additionally fetch records, which do not have a parent in the default language.
Default
0

selectFields

Property
selectFields
Data type
string / stdWrap
Description

List of fields to select, or count(*).

If the records need to be localized, please include the relevant localization-fields (uid, pid, languageField and transOrigPointerField). Otherwise the TYPO3 internal localization will not succeed.

Default
*

join, leftjoin, rightjoin

Property
join, leftjoin, rightjoin
Data type
string / stdWrap
Description
Enter the table name for JOIN, LEFT OUTER JOIN and RIGHT OUTER JOIN respectively.

markers

Property
markers
Data type
(array of markers)
Description

The markers defined in this section can be used, wrapped in the usual ###markername### way, in any other property of select. Each value is properly escaped and quoted to prevent SQL injection problems. This provides a way to safely use external data (e.g. database fields, GET/POST parameters) in a query.

Available sub-properties:

<markername>.value (value)
Sets the value directly.
<markername>.commaSeparatedList (boolean)
If set, the value is interpreted as a comma-separated list of values. Each value in the list is individually escaped and quoted.
(stdWrap properties ...)
All stdWrap properties can be used for each markername.

Example

page.60 = CONTENT
page.60 {
      table = tt_content
      select {
         pidInList = 73
         where = header != ###whatever###
         orderBy = ###sortfield###
         markers {
            whatever.data = GP:first
            sortfield.value = sor
            sortfield.wrap = |ting
         }
      }
}

This example selects all records from table tt_content, which are on page 73 and which don't have the header set to the value provided by the Get/Post variable "first", ordered by the content of the column "sorting".
