Hi In my application I have a .php file which is working separetly direcly with DB to take data from there and make chained selects.
ajax.functions.php
Code:
// Get regions options
if (isset($_GET["func"]) and $_GET["func"] == 'get_regions' and isset($_GET["value"])) {
$res = $db->query("SELECT id, region FROM region WHERE country_id = '".$_GET["value"]."' ORDER BY region");
$options = '';
if ($_GET["value"] != '0') while ($line = $res->fetch($res)) {
$options .= "selbox.options[selbox.options.length] = new Option('".$line["region"]."','".$line["id"]."');";
}
echo "var selbox = ".$_GET["sel"].";
selbox.options.length = 0;
selbox.options[selbox.options.length] = new Option('Выберите Регион','0');
".$options;
}
// Get ciries options
if (isset($_GET["func"]) and $_GET["func"] == 'get_cities' and isset($_GET["value"])) {
$res = $db->query("SELECT id, city FROM city WHERE region_id = '".$_GET["value"]."'");
$options = '';
if ($_GET["value"] != '0') while ($line = $res->fetch($res)) {
$options .= "selbox.options[selbox.options.length] = new Option('".$line["city"]."','".$line["id"]."');";
}
echo "var selbox = ".$_GET["sel"].";
selbox.options.length = 0;
selbox.options[selbox.options.length] = new Option('Выберите Город','0');
".$options;
}
// Get subcategories checkboxes
if (isset($_GET["func"]) and $_GET["func"] == 'get_subcats' and isset($_GET["value"])) {
$options = '';
$res = $db->query("SELECT id, category_name FROM t_categories WHERE parent_id = '".$_GET["value"]."'");
if ($_GET["value"] != '0') while ($line = $res->fetch($res)) {
$options .= "selbox.options[selbox.options.length] = new Option('".$line["category_name"]."','".$line["id"]."');";
}
echo "var selbox = ".$_GET["sel"].";
selbox.options.length = 0;
selbox.options[selbox.options.length] = new Option('Выберите подкатегорию','0');
".$options;
}
here is main code, beforethat comes connection and class for working with mysql.
ajax.js which is below is making parsing as I understand
Code:
function ajax_do (url) {
var jsel = document.createElement('SCRIPT');
jsel.type = 'text/javascript';
jsel.src = url + '&t;=<? echo time();?>';
document.body.appendChild (jsel);
return true;
}
And I have selects
Code:
<select name="country">
<option value=0 selected>Choose Country</option>
<? $this->db->select('*');
$this->db->from('country');
$query= $this->db->get();
foreach($query->result_array() as $row){
$id=$row['id'];
$cat_name=$row['country'] ;
echo" <option value=\"$id\">$cat_name</option> ";
}
?>
</select>
Region <select name="region"></select>
City<select name="city"></select>
What is the best way to put functions of calling region and city in CI?
I have tried to put them in controlley ajax_functions.php
and call like thisonChange="ajax_do('/ajax_functions/get_cities/'+this.value+'/document.add_tender.city');" />
and I have made in ajax_functions like this
Code:
function get_cities($value,$sel){
$res = $this->db->query("SELECT id, city FROM city WHERE region_id = '".$_GET["value"]."'");
$options = '';
if ($value != '0') {
foreach ($res->result_array() as $line) {
$options .= "selbox.options[selbox.options.length] = new Option('".$line["city"]."','".$line["id"]."');";
}
}
echo "var selbox =$sel;
selbox.options.length = 0;
selbox.options[selbox.options.length] = new Option('Choose City','0');
".$options;
}
Not working
What's up?
