+ ["options"]["sql_type_column"] - the name of the SQL column that |
|
|
| contains the 'Type' field. |
|
|
| ["options"]["sql_string"]* - the SQL string to use when getting data. |
|
|
| ["options"]["sql_connection_id"] - the SQL connection id to the |
|
|
| database server. |
|
|
| ["options"]["indent"] - the character to use for indentation. |
|
|
| ["options"]["remove_action"]* - the URL to use when removing an item. |
|
|
| ["options"]["sql_delete_table_name"] - the table name to use when |
|
|
| deleting items from a tree. |
|
|
| ["remove_branch"] - set to 'true' when you want to delete items |
|
|
| instead of drawing them on the screen. |
|
|
| ["branch_to_remove"] - the id of the starting branch to delete. |
|
|
| |
|
|
| Items: |
|
|
| ["item"][<NUM>] - the name of the 'Type', must match values exactly |
|
|
| to the SQL 'Type' column. |
|
|
| ["item_action"][<NUM>]* - the URL to use when an item is clicked. |
|
|
| ["item_td_code"][<NUM>]* - extra code to be included in the TD |
|
|
| |
|
|
| * - these items are passed to PHP's eval function before being passed |
|
|
| back to the browser, put and runtime code here. |
|
|
| |
|
|
| Once the array is created, make sure it is passed to the 'GrowTree' |
|
|
| function to draw the tree. |
