| | 3 | The following template provides a match template that automatically adds a `value` attribute to any `<input>` element that has matching data in the context. |
| | 4 | |
| | 5 | {{{ |
| | 6 | #!xml |
| | 7 | <html xmlns:py="http://markup.edgewall.org/"> |
| | 8 | |
| | 9 | <input py:match="form//input" py:attrs="select('@*')" |
| | 10 | value="${form[str(select('@name'))]}" /> |
| | 11 | |
| | 12 | <form action="" method="POST"> |
| | 13 | <p> |
| | 14 | <label>Something: <input type="text" name="something"/></label> |
| | 15 | </p> |
| | 16 | </form> |
| | 17 | </html> |
| | 18 | }}} |
| | 19 | |
| | 20 | Assuming the context data contained a variable “form” that was `{'something': 'Look, Ma'}`, the output would look as follows: |
| | 21 | |
| | 22 | {{{ |
| | 23 | #!xml |
| | 24 | <html> |
| | 25 | <form action="" method="POST"> |
| | 26 | <p> |
| | 27 | <label>Something: <input value="Look, Ma" type="text" name="something" /></label> |
| | 28 | </p> |
| | 29 | <input value="Send" type="submit" /> |
| | 30 | </form> |
| | 31 | </html> |
| | 32 | }}} |
| | 33 | |
| | 34 | This recipe would need to be extended to also support checkboxes, select fields, and so on. |
