Placeholder text for the field. This can be a simple string or a reference to a value in the current record or another one. With a syntax like
__row|field
the placeholder will take the value of the given field from the current record.This can be recursive to follow a longer path in a table record chain. If the designated field is a relation to another table (is of type select, group or inline), the related record will be loaded and the placeholder searched within it.
Example from the "sys_file_reference" table:
'title' => [ 'l10n_mode' => 'prefixLangTitle', 'exclude' => true, 'label' => 'LLL:EXT:core/Resources/Private/Language/locallang_tca.xlf:sys_file_reference.title', 'config' => [ 'type' => 'input', 'size' => 20, 'max' => 255, 'nullable' => true, 'placeholder' => '__row|uid_local|metadata|title', 'mode' => 'useOrOverridePlaceholder', 'default' => null, ], ],
In the above placeholder syntax,
uid_local
points to the related "sys_file" record andmetadata
points to the "sys_file_metadata" of the related "sys_file" record. From there we take the content of thetitle
field as placeholder value.
