|---|
| 17 | * AgaviFormPopulationFilter automatically populates a form that is re-posted, |
|---|
| 18 | * which usually happens when a View::INPUT is returned again after a POST |
|---|
| 19 | * request because an error occured during validation. |
|---|
| 20 | * That means that developers don't have to fill in request parameters into |
|---|
| 21 | * form elements in their templates anymore. Text inputs, selects, radios, they |
|---|
| 22 | * all get set to the value the user selected before submitting the form. |
|---|
| 23 | * If you would like to set default values, you still have to do that in your |
|---|
| 24 | * template. The filter will recognize this situation and automatically remove |
|---|
| 25 | * the default value you assigned after receiving a POST request. |
|---|
| 26 | * This filter only works with POST requests, and compares the form's URL and |
|---|
| 27 | * the requested URL to decide if it's appropriate to fill in a specific form |
|---|
| 28 | * it encounters while processing the output document sent back to the browser. |
|---|
| 29 | * Since this form is executed very late in the process, it works independently |
|---|
| 30 | * of any template language. |
