multisite – Mengirim data menggunakan metode GET tidak berfungsi dengan benar

Saya menggunakan WP 3.5.2 dan WPMU. Saya mengembangkan satu halaman http://baohiem.info/chon-mat-gui-vang. Halaman ini menggunakan $wpdb global untuk menanyakan tabel _blogs.(_blogs telah disesuaikan, menambahkan beberapa bidang.) Saat mengirimkan formulir, saya menggunakan metode GET, tetapi, ketika masuk, saya memiliki data ($_REQUEST; $_GET) tetapi tidak masuk , tidak ada data. Mengapa? Saya tidak mengerti apa yang terjadi. Ada yang bisa bantu saya?

Terima kasih.

<?php
get_header(); 
?>

        <form action="" method="get">
            <input id="searchfield-cmgv" type="text" name="hoten" placeholder="Họ và tên tư vấn viên...." size="35" value="<?=$_REQUEST['hoten']?>"/>

url: http://baohiem.info/chon-mat-gui-vang/?hoten=&location=Hải+Phòng&company=Prudential tidak berfungsi. Saya tidak bisa mendapatkan[‘location’],Mendapatkan[‘hoten’],Mendapatkan[‘company’]

Terselesaikan: Saya menggunakan plugin Better WP Security dan memfilter URL saya.

Untuk mengaktifkan parameter passing seperti: example.com?src=SomeSource&page=1….. Masuk ke ACP Anda. Keamanan WP/Sistem Tweak yang lebih baik dan hapus centang pada opsi “Filter String Kueri yang Mencurigakan”.

Catatan: perhatian dengan parameter Anda aman untuk situs Anda 🙂

Selamat natal.
