オートコンプリートフィールドのソースとして含めようとしているデータは、各行の1番目と2番目（郵便番号と郊外）のフィールドです。しかし、郵便番号と郊外は州でフィルタリングされます。たとえば、ACTはすべての郵便番号がアクティブな状態であり、郊外はオートコンプリートのソースです。そして、私array_unique()は繰り返されたデータを削除するために使用しました。
//take area from state
function take_area(){
global $wpdb;
$uploads = wp_upload_dir();
$upload = $uploads[baseurl];
$file = $upload.'/csv/suburb_and_area.txt';
$f = fopen($file, 'r');
$state = $_POST['state'];
$counter = 0;
while($line = fgets($f, 4096)){
$details = explode(',', $line);
$counter++;
if(trim($details[2]) == $state){
$state_arr[$counter] = $details[1];
}
}
$option = '';
if($state!=''){
$c=0;
$area_of_state = array_unique($state_arr);
foreach($area_of_state as $area){
if($c>0){$option .= ', ';}
$option .= '"'.$area.'"';
$c++;
}
}
echo $option;
}
およびJavaScript：
$("#state").change(function(){
var state = $('#state :selected').attr('data-value');
if(!state){
state = $('#state').val();
}
$.ajax({
url:"<?php bloginfo('wpurl'); ?>/wp-admin/admin-ajax.php",
type:'POST',
data:'action=take_area_from_state&state=' + state,
success:function(results){
if(results!=0){
$("#area").removeAttr("disabled");
$("#area").empty();
var source = [results];
$("#area").autocomplete({source: source});
}else{
$("#area").attr("disabled", "disabled");
}
}
});
});
