I am trying to write a script that allows me to show only the states for the country selected in another dropdown list.
Given: {html_options values=$states_values output=$states_output selected=$formdata.state}
Given: my database lists all 50 states + Canadian provinces + Mexican states (so it one long list).
Given: I filter for just provinces (so the state dropdown list has only Canadian provinces in it), and
Given: On reload of the page, selected=$formdata.state will select the state in the values-posted array. Does Smary select the state by index or by value? If I select Saskatchewan, that would be an index of 62, but without all the US states, it would be an actual index of 12.
The ultimate question is, can I have a country selector with Smarty where I can dynamically populate and repopulate a state dropdown (with JavaScript) and have the state remembered and re-selected with selected=$formdata.state when returning to the page? |

Sure! The way I see it, Smarty doesn't really come into play unless you write your own custom plugin to encapsulate all of the js code and conditions that you have. Otherwise, what you need to do is have your page know which array is currently selected, which I think you already have in another dropdown for country (?). In otherwords, I don't see how this is any different from a normal select in terms of the form handling. You should be able to Do What You Expect(tm).
I noticed that you cross-posted this in two forums--that is unnecessary and I have removed the other one in case you are looking for it. One post is not only sufficient, it also keeps all replies together for future reference. |
