insert multiple image data into database with codeigniter - php

Question

i have a problem for looping data and save to database. the result of this insert data contains only one. and what is the differences in insert() with insert_batch() ? i'm sorry CTRL + K on my keyboard is not function.
my view :
<?php echo form_open('proses_tambah_produk')?>
<input type="file" id="gambar2" name="gambar_tambah[]" class="form-control" style="width:90%;display:initial;margin-right:10px;margin-bottom:5px;">
<label style="background-color:red;color:white;border-radius:50%;padding:3px;" id="idGambar2" class="hapus_gambar glyphicon glyphicon-remove"></label>
<input type="file" id="gambar2" name="gambar_tambah[]" class="form-control" style="width:90%;display:initial;margin-right:10px;margin-bottom:5px;">
<label style="background-color:red;color:white;border-radius:50%;padding:3px;" id="idGambar2" class="hapus_gambar glyphicon glyphicon-remove"></label>
<?php echo form_close()?>
my controller :
function proses_tambah_produk(){
$config['upload_path'] = 'assets/img/produk';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = 1000;
$config['overwrite'] = TRUE;
//$config['max_width'] = 1024;
//$config['max_height'] = 768;
$this->load->library('upload', $config);
$files = $_FILES;
$count = count($_FILES['gambar_tambah']['name']);
for($i=0; $i<$count; $i++)
{
$_FILES['gambar_tambah']['name']= $files['gambar_tambah']['name'][$i];
$_FILES['gambar_tambah']['type']= $files['gambar_tambah']['type'][$i];
$_FILES['gambar_tambah']['tmp_name']= $files['gambar_tambah']['tmp_name'][$i];
$_FILES['gambar_tambah']['error']= $files['gambar_tambah']['error'][$i];
$_FILES['gambar_tambah']['size']= $files['gambar_tambah']['size'][$i];
$this->upload->do_upload('gambar_tambah');
$upload_data = $this->upload->data();
$name_array[] = $upload_data['file_name'];
$fileName = $upload_data['file_name'];
$images[] = $fileName;
}
$fileName = $images;
$tambahan = $_FILES['gambar_tambah']['name'];
$this->produk_adm->add($data, $gambar, $tambahan);
}
my model :
function add($tambahan){
$last_insert_id = $this->db->insert_id();
$data_gambar = array(
'id_produk' => $last_insert_id,
'gambar' => $tambahan,
);
$this->db->insert('produk_image', $data_gambar);
return $this->db->insert_id();
}

Answer 1

$filesCount = count($_FILES['photo_gallery']['name']);
for($i = 0; $i < $filesCount; $i++){
$_FILES['gambar_tambah']['name'] = $_FILES['photo_gallery']['name'][$i];
$_FILES['gambar_tambah']['type'] = $_FILES['photo_gallery']['type'][$i];
$_FILES['gambar_tambah']['tmp_name'] = $_FILES['photo_gallery']['tmp_name'][$i];
$_FILES['gambar_tambah']['error'] = $_FILES['photo_gallery']['error'][$i];
$_FILES['gambar_tambah']['size'] = $_FILES['photo_gallery']['size'][$i];
$file_name=$this->crud->upload_file('gambar_tambah',$upload_image_path);
$image_data[$i]['image'] = $file_name;
$this->crud->add('table_name',$image_data[$i]);
}

Answer 2

you can't use same id name twice. The id value must be unique for every field. Your code for upload is wrong you are assigning value of
$_FILES['gambar_tambah']['name']= $files['gambar_tambah']['name'][$i];
You can't do this insted you just assign value to a variable like
$image_name = $_FILES['gambar_tambah']['name'];
and insert that into database every time when loop runs or make array of it and insert it into one filed by implode function.

Answer 3

when you are calling model you have used three parameters and in model you are using one.
use
$this->load->model('produk/adm');
$this->produk_adm->add($tambahan);
instead of
$this->produk_adm->add($data, $gambar, $tambahan);
and in model
function add($tambahan){
$last_insert_id = $this->db->insert_id();
$data_gambar = array(
'id_produk' => $last_insert_id, // if it is auto increment in db, remove this line
'gambar' => $tambahan,
);
$this->db->insert('produk_image', $data_gambar);
return $this->db->insert_id();
}
