Field FieldSelect

public class FieldSelect extends Field

field.select.php #14

A simple Select field that essentially maps to HTML's <select/>. The options for this field can be static, or feed from another field.

Methods

void __construct()

Construct a new instance of this field.

boolean allowDatasourceOutputGrouping()

Test whether this field supports data-source output grouping. This default implementation prohibits grouping. Data-source grouping allows clients of this field to group the XML output according to this field. Subclasses should override this if grouping is supported.

Returns

true if this field does support data-source grouping, false otherwise.

boolean allowDatasourceParamOutput()

Test whether this field supports data-source parameter output. This default implementation prohibits parameter output. Data-source parameter output allows this field to be provided as a parameter to other data-sources or XSLT. Subclasses should override this if parameter output is supported.

Returns

true if this supports data-source parameter output, false otherwise.

void appendFormattedElement(XMLElement $wrapper, array $data, bool $encode, string $mode, integer $entry_id)

Append the formatted XML output of this field as utilized as a data source.

Since Symphony 2.5.0, it will defaults to prepareReadableValue return value.

Parameters
  • $wrapper XMLElementthe XML element to append the XML representation of this to.

  • $data arraythe current set of values for this field. the values are structured as for displayPublishPanel.

  • $encode bool(optional) flag as to whether this should be html encoded prior to output. this defaults to false.

  • $mode stringA field can provide ways to output this field's data. For instance a mode could be 'items' or 'full' and then the function would display the data in a different way depending on what was selected in the datasource included elements.

  • $entry_id integer(optional) the identifier of this field entry instance. defaults to null.

boolean buildDSRetrievalSQL(array $data, string $joins, string $where, bool $andOperation)

Construct the SQL statement fragments to use to retrieve the data of this field when utilized as a data source.

Parameters
  • $data arrayAn array of the data that contains the values for the filter as specified in the datasource editor. The value that is entered in the datasource editor is made into an array by using + or , to separate the filter.

  • $joins stringA string containing any table joins for the current SQL fragment. By default Datasources will always join to the tbl_entries table, which has an alias of e. This parameter is passed by reference.

  • $where stringA string containing the WHERE conditions for the current SQL fragment. This is passed by reference and is expected to be used to add additional conditions specific to this field

  • $andOperation bool(optional) This parameter defines whether the $data provided should be treated as AND or OR conditions. This parameter will be set to true if $data used a + to separate the values, otherwise it will be false. It is false by default.

Returns

True if the construction of the SQL was successful, false otherwise.

boolean canFilter()

Test whether this field can be filtered. This default implementation prohibits filtering. Filtering allows the XML output results to be limited according to an input parameter. Subclasses should override this if filtering is supported.

Returns

true if this can be filtered, false otherwise.

boolean canPrePopulate()

Test whether this field can be prepopulated with data. This default implementation does not support pre-population and, thus, returns false.

Returns

true if this can be pre-populated, false otherwise.

boolean canToggle()

Test whether this field can be toggled using the With Selected menu on the Publish Index.

Returns

true if it can be toggled, false otherwise.

integer checkFields(array $errors, bool $checkForDuplicates)

Returns

returns the status of the checking. if errors has been populated with any errors self::__ERROR__, self::__OK__ otherwise.

boolean commit()

Commit the settings of this field from the section editor to create an instance of this field in a section.

Returns

true if the commit was successful, false otherwise.

boolean createTable()

The default field table construction method. This constructs the bare minimum set of columns for a valid field table. Subclasses are expected to overload this method to create a table structure that contains additional columns to store the specific data created by the field.

Parameters
  • $value mixedthe value to find the associated entry count for, this usually comes from the fetchAssociatedEntrySearchValue function.

Returns

this default implementation returns void. overriding implementations should return an integer.

See Also
void|array fetchAssociatedEntryIDs(mixed $value)

Fetch the Entry ID's associated with this field instance given a $value, where the $value can be anything. This function is unused by Symphony core but should be implemented by Fields that maintain relationships.

Parameters
  • $value mixedthe value to find the associated entry ID's for.

Returns

this default implementation returns void. overriding implementations should return an array of the associated entry ids.

Deprecated

@since Symphony 2.5.0 this method is not called anymore in the core. Please use Field::findRelatedEntries and Field::findParentRelatedEntries instead.

array|string fetchAssociatedEntrySearchValue(array $data, integer $field_id, integer $parent_entry_id)

Accessor to the associated entry search value for this field instance. This default implementation simply returns $data

Parameters
  • $data arraythe data from which to construct the associated search entry value, this is usually Entry with the $parent_entry_id value's data.

  • $field_id integer(optional) the ID of the field that is the parent in the relationship

  • $parent_entry_id integer(optional) the ID of the entry from the parent section in the relationship

Returns

Defaults to returning $data, but overriding implementation should return a string

Allows a field to set default settings.

Parameters
  • $settings arraythe array of settings to populate with their defaults.
