hasNullCheckboxButNoPlaceholder()

Returns true if the "null value" checkbox should be rendered. This is used in some "text" based types like "text" and "input" for some renderType's.

protected hasNullCheckboxButNoPlaceholder() : bool

A field has eval=null set, but has no useOverridePlaceholder defined. Goal is to have a field that can distinct between NULL and empty string in the database. A checkbox and an additional hidden field will be created, both with the same name and prefixed with "control[active]". If the checkbox is set (value 1), the value from the casual input field will be written to the database. If the checkbox is not set, the hidden field transfers value=0 to DataHandler, the value of the input field will then be reset to NULL by the DataHandler at an early point in processing, so NULL will be written to DB as field value.

All that only works if the field is not within flex form scope since flex forms can not store a "null" value or distinct it from "empty string".

Return values
bool

hasNullCheckboxWithPlaceholder()

Returns true if the "null value" checkbox should be rendered and the placeholder handling is enabled. This is used in some "text" based types like "text" and "input" for some renderType's.

protected hasNullCheckboxWithPlaceholder() : bool

A field has useOverridePlaceholder set and null in eval and is not within a flex form. Here, a value from a deeper DB structure can be "fetched up" as value, and can also be overridden by a local value. This is used in FAL, where eg. the "title" field can have the default value from sys_file_metadata, the title field of sys_file_reference is then set to NULL. Or the "override" checkbox is set, and a string or an empty string is then written to the field of sys_file_reference. The situation is similar to hasNullCheckboxButNoPlaceholder(), but additionally a "default" value should be shown. To achieve this, again a hidden control[hidden] field is added together with a checkbox with the same name to transfer the information whether the default value should be used or not: Checkbox checked transfers 1 as value in control[active], meaning the overridden value should be used. Additionally to the casual input field, a second field is added containing the "placeholder" value. This field has no name attribute and is not transferred at all. Those two are then hidden / shown depending on the state of the above checkbox in via JS.

Return values
bool

initializeResultArray()

Initialize the array that is returned to parent after calling. This structure is identical for *all* nodes. Parent will merge the return of a child with its own stuff and in itself return an array of the same structure.

protected initializeResultArray() : array<string|int, mixed>
Return values
array<string|int, mixed>

mergeChildReturnIntoExistingResult()

protected mergeChildReturnIntoExistingResult(array<string|int, mixed> $existing, array<string|int, mixed> $childReturn[, bool $mergeHtml = true ]) : array<string|int, mixed>

The incoming $childReturn array should be initialized using initializeResultArray() beforehand.

Array returned by child

$mergeHtml : bool = true
