Tidak Ada Notifikasi Salah Input captcha di Swarakalibata Ci

Assalam,.. Mohon bantuannya mas

Assalam,.. Ketika salah input captcha ga ada notif dulu tapi langsung redirext ke home, apakah tidak ada script pengecekan captcha nya? 

Assalam,.. iya gan termasuk tidak notif khusus jika username / nickname sama... sedangkan field nickname itu jadi primary.... :) :)

Assalam,.. pada sikolag ci tidak ada modul kontributor mas
mungkin maksudnya pada swarakalibata ci?
 
cara untuk menambahkan notifikasi bisa dengan js :
cukup dengan begini saja, buka file "application/controllers/kontributor.php" pada baris 66 cari script berikut :
}
  redirect('administrator/home');
 
ubah menjadi :
redirect('administrator/home');
}else{
	echo "<script>window.alert('Maaf, Anda Tidak Memiliki akses');
  			window.location=('".base_url()."kontributor')</script>";
}
 
simpan dan selesai.

Assalam,.. Kenapa ga berfungsi mas validasinya ya, saya udh coba pasang 

Assalam,.. Penempatan nya redirect ke home dulu atau echo alart dulu mas

Assalam,.. Alhamdulillah bisa mas, terima kasih 

Assalam,.. Kalau misalkan redirect nya di ganti gimana mas jadi ketika di eksekusi dan captcha salah tidak redirect ke halaman, tapi focus ke inputan captcha, soalnya kalau redirect itu kan jadi ke reload dan harus isi data dari awal

Assalam,.. maaf mas pada fom kontributor Swarakalibata ketika input username yg sama malah error saya sudah coba pake cara ini 
https://members.phpmu.com/forum/read/notif-menginputkan-data-yang-sama namun masih gagal, kira-kira penempatan nya untuk di  Swarakalibata pa form kontributor bagaimana

Assalam,.. Mas "Ujang Rukman" mohon rubah telebih dahulu judul pertanyaan Forumnya ke "Tidak Ada Notifikasi Salah Input captcha di Swarakalibata CI" (Bukan SIKOLAG. 
 
Selanjutnya : Mas "Bukhori Al Muslim" : Notif / Alert berhasil muncul. Namun, Image / Gambar berhasil terupload. (Khawatir hal ini akan membebani Server). Mohon solusinya. :)

Assalam,.. Selanjutnya : Mas "Bukhari Al Muslim" : Notif / Alert berhasil muncul. Namun, Image / Gambar berhasil terupload. (Khawatir hal ini akan membebani Server). Mohon solusinya. :)

Assalam,.. saya aman mas, kalau error tidak masuk semua nya

Assalam,.. coba bagi script mas
