  2. /**
  3. * Contains all the functionality required to be able to edit the core server
  4. * settings. This includes anything from which an error may result in the forum
  5. * destroying itself in a firey fury.
  6. *
  7. * Adding options to one of the setting screens isn't hard. Call prepareDBSettingsContext;
  8. * The basic format for a checkbox is:
  9. * array('check', 'nameInModSettingsAndSQL'),
  10. * And for a text box:
  11. * array('text', 'nameInModSettingsAndSQL')
  12. * (NOTE: You have to add an entry for this at the bottom!)
  13. *
  14. * In these cases, it will look for $txt['nameInModSettingsAndSQL'] as the description,
  15. * and $helptxt['nameInModSettingsAndSQL'] as the help popup description.
  16. *
  17. * Here's a quick explanation of how to add a new item:
  18. *
  19. * - A text input box. For textual values.
  20. * array('text', 'nameInModSettingsAndSQL', 'OptionalInputBoxWidth'),
  21. * - A text input box. For numerical values.
  22. * array('int', 'nameInModSettingsAndSQL', 'OptionalInputBoxWidth'),
  23. * - A text input box. For floating point values.
  24. * array('float', 'nameInModSettingsAndSQL', 'OptionalInputBoxWidth'),
  25. * - A large text input box. Used for textual values spanning multiple lines.
  26. * array('large_text', 'nameInModSettingsAndSQL', 'OptionalNumberOfRows'),
  27. * - A check box. Either one or zero. (boolean)
  28. * array('check', 'nameInModSettingsAndSQL'),
  29. * - A selection box. Used for the selection of something from a list.
  30. * array('select', 'nameInModSettingsAndSQL', array('valueForSQL' => $txt['displayedValue'])),
  31. * Note that just saying array('first', 'second') will put 0 in the SQL for 'first'.
  32. * - A password input box. Used for passwords, no less!
  33. * array('password', 'nameInModSettingsAndSQL', 'OptionalInputBoxWidth'),
  34. * - A permission - for picking groups who have a permission.
  35. * array('permissions', 'manage_groups'),
  36. * - A BBC selection box.
  37. * array('bbc', 'sig_bbc'),
  38. * - A list of boards to choose from
  39. * array('boards', 'likes_boards'),
  40. * Note that the storage in the database is as 1,2,3,4
  41. *
  42. * For each option:
  43. * - type (see above), variable name, size/possible values.
  44. * OR make type '' for an empty string for a horizontal rule.
  45. * - SET preinput - to put some HTML prior to the input box.
  46. * - SET postinput - to put some HTML following the input box.
  47. * - SET invalid - to mark the data as invalid.
  48. * - PLUS you can override label and help parameters by forcing their keys in the array, for example:
  49. * array('text', 'invalidlabel', 3, 'label' => 'Actual Label')
