getRequiredFieldsQuery()

Construct a query (to be used as a sub-select) to view the fields of the given form. It always will return the id of the form as well @param callback $field_refernece_callback. A callback function whose first arguement is the form, the second arguements is the field and which returns the way the field value should be references as a field. If the callback is null (the default) then the reference used is "$form+$field"

    • string $form
    • mixed $fields
      Either a string, the field, or an array of string, the fields.

      Defaults to null. If non-null it is the id that we wish to limit to.
      • Default Value: null

      • Default Value: false
    • integer $mod_time
      Defaults to -1. If non-negative, we only list the requested fields for an id if at least one of them has a modification time greater than or equal to $mod_time. If the form storage has no way of tracking modifucation time, all entries are listed.

    • array $fields
      A list of fields to look up and return.
    • string $delim
      The delimiter to put between returned fields if there are more than one. If false, it returns it as an array.
  • Returns: string
    false on failure

  • Parameters:
    • string $form
      The form name.
    • boolean $parent
      Defaults to false. If it is scalar and non-boolean, it is consider to be the ID of the parent, and then we get all forms with parent the given id.
      • Default Value: false

      Defaults to false. It true, returns only one result. If an integer it is the numeber of records to limit to. If it is as an array of two integers, it is the offset and then number of results to limit to.
      • Default Value: false
  • Returns: mixed
    an array of matching form ids. However, ff $limit_one is true or 1 or array ($offset,1) then then we return either the id or false, if none found or there was an error.
