POChanging smarty variable's value with AJAX; multiple selects
text
Body
copied!<p>I have 3 selects on a page, the 2nd and 3rd select should populate with options depending on the value selected in the first select. For instance: the first select has a list of countries, if I select country <strong>A</strong> from this select, the 2nd select will populate with cities from this country, the 3rd select populates with, i don't know, most popular names in the country.</p> <p>I want to realize this with AJAX, but because the site is written with the use of Smarty, I'm having a hard time. Each select is populated by an array which is assigned from a php. I would like to somehow change the values of the 2nd and 3rd array, without reloading the page, depending on an id I get from the 1st select. </p> <p>I tried requesting the page that assigns the values to smarty and tried changing the arrays but it didn't work in the frontend. Any ideas?</p> <p><strong>EDIT:</strong> The code looks something like this:</p> <pre><code>$countries = Country::getCountries(); $cities = City::getCities($country_id); //the parameter is not necessary $names = Name::getNames($country_id); //the parameter is not necessary $smarty->assign("countries",$countrires); $smarty->assign("cities",$cities); $smarty->assign("names",$names); //display template etc </code></pre> <p>on the template page</p> <pre><code><select name="countries"> {foreach from=$countries item=country} <option value="{$country.id}">{$country.name}</option> {/foreach} </select> </code></pre> <p>and the 2 other selects look the same. </p>
