A link to help for the component will be included if one is specified. |
| |
|
| |
All inputs can be undef without problems. |
| |
|
| |
Inputs: $component (the text on the right side of the breadcrumbs trail), |
| |
$component_help |
| |
$menulink (boolean, controls whether to include a link to /adm/menu) |
| |
$helplink (if 'nohelp' don't include the orange help link) |
| |
$css_class (optional name for the class to apply to the table for CSS) |
| |
$no_mt (optional flag, 1 if &mt() is _not_ to be applied to $component |
| |
when including the text on the right. |
| |
Returns a string containing breadcrumbs for the current page. |

| |
|
| |

# Uses nested tables to divide form elements into segments. |

# For examples of use see loncom/interface/lonnotify.pm |
| |
# |
| |
# Can be used in following order: ... |
| |
# &start_pick_box() |
| |
# row1 |
| |
# row2 |
| |
# row3 ... etc. |
| |
# &submit_row() |

# &end_pick_box() |
| |
# |

# where row1, row 2 etc. are chosen from &role_select_row,&course_select_row, |
| |
# &status_select_row and &email_default_row |
| |
# |
| |
# Can also be used in following order: |

# &row_title() |

# &row_closure() ... etc. |
| |
# &submit_row() |
| |
# &end_pick_box() |
| |
# |
| |
# In general a &submit_row() call should proceed the call to &end_pick_box(), |
| |
# as this routine adds a button for form submission. |
| |
# &submit_row() does not require a &row_closure after it. |
| |
# |
| |
# &start_pick_box() creates a bounding table with 1-pixel wide black border. |
| |
# rows should be placed between calls to &start_pick_box() and &end_pick_box. |
| |
# |
| |
# &row_title() adds a title in the left column for each segment. |
| |
# &row_closure() closes a row with a 1-pixel wide black line. |
| |
# |
| |
# &role_select_row() provides a select box from which to choose 1 or more roles |
| |
# &course_select_row provides ways of picking groups of courses |
| |
# radio buttons: all, by category or by picking from a course picker pop-up |
| |
# note: by category option is only displayed if a domain has implemented |
| |
# selection by year, semester, department, number etc. |
| |
# |
| |
# &status_select_row() provides a select box from which to choose 1 or more |
| |
# access types (current access, prior access, and future access) |
| |
# |

# &email_default_row() provides text boxes for default e-mail suffixes for |
| |
# different authentication types in a domain. |
| |
# |
