 Posted: Fri Nov 23, 2007 4:41 am Post subject: passing values not showing up in the datagrid |
 |
|
I am using smarty as the renderer and I want to pass an ID but not show it in the rendered datagrid. Here is an example of my sql..
| Code: | $dg->bind("SELECT id, title, location FROM jobs", $bind_options, DATAGRID_SOURCE_MDB2);
|
Is there a way to do this?
THanks |

| Simply add the columns yourself. (If you don't do it, SDG will add columns for every column in your SQL query.) |

The data should still be available in the renderer (e.g. Smarty), even if you output just one column but fetch e.g. five columns from the database. |

| The data is not in the renderer. The only things that get set in the smarty renderer are the values that are selected in the sql or that you create columns for. |

Well isn't that exactly what you wanted to have? Please provide an example if it isn't. |

I want to use this sql
| Code: | | $dg->bind("SELECT id, title, location FROM jobs", $bind_options, DATAGRID_SOURCE_MDB2); |
and have the datagrid look like this
| Code: |
+----------+-----------+
| Title | Location |
+----------+-----------+
|value | value |
+----------+-----------+
|
In the smart object I want each ID with out its display in the rendered datagrid. |

| so i am guessing no one knows how to do this. I think this should be added as a feature in a future release of the smarty renderer. |

More patience please. 
Maybe we're talking about different things, but the data *is* available. Every field that you select in your SQL query is available in formatters.
Therefore, if you e.g. add a column for one of the fetched field and another "dummy" column that uses a formatter function, this formatter function has access to every of the fetched fields. |

"Dummy" was meant in the way that the column is not directly related to a field in your SQL query. Let's assume that you have added one ore more columns that are related to the SQL query (in your example e.g. title and location). Now you can do something like this:
| Code: |
$column = new Structures_DataGrid_Column('Title', 'title', 'title', array('align' => 'center'), 'N/A', 'formatter');
$dg->addColumn($column);
|
Note that all strings and the attributes array in this code sample are just examples, change them to your needs. This is also true for the name of the formatter function, 'formatter' is maybe not the best name.
Now you need to define this formatter function:
| Code: |
function formatter($params)
{
var_dump($params);
return 'example123';
}
|
This new column will then show 'example123' in every row, but also multiple times the data that is stored in $params. Look at it -- it contains the values that you're looking for. Then, make the function do what you need. |
