codeigniter insert many images name into database - php

Question

I am build uploader images and store it into database, I already can upload many images to folder, but I can't insert all images name that uploaded, and I don't know how to insert into database, first I have put commend on my code below when error occur, second I don't know the query to put it in database if the image count is different e.g 1-10 images, last question, if I do query "SELECT id..." and I want to return it, is there method to return it into string or int? If I use row() it will return stdClass object. please help me,
below is my code:
controller :
$this->load->library("myupload", "form_validation");
$this->load->model("testModel");
$barangImage = array();
if($this->input->post("formSubmit")) {
$this->form_validation->set_rules("nama", "Nama", "required|trim");
if($this->form_validation->run()) {
$insertData = array(
"nama" => $this->input->post("nama")
);
if($id = $this->testModel->add($insertData)) {
//print_r($id);
if(isset($_FILES) && $image = $this->myupload->uploadFile($_FILES)) {
//$image here is already fill with all images name
if(isset($image["error"]) && $image["error"]) {
echo $image["error"];
}else {
foreach($image as $img) {
$barangImage = array(
"gambar" => $img,
"barangid" => $id
);
}
//but when i put into barangImage,
//it only stored last image name
print_r($barangImage);
//output `Array ( [gambar] => 2.JPG [barangid] => Array ( [id] => 52 ) )`
}
}
if($id = $this->testModel->add_images($barangImage)) {
echo "SUCCESS !!!";
}else {
echo "FAIL INSERT IMAGES!!!";
}
}else {
echo "FAIL INSERT DATA NAMA";
}
}else {
echo "FAIL VALIDASI RUN";
}
}
model :
public function add($newData){
$this->db->insert("cobabarang", $newData);
$nama = $newData["nama"];
$id = $this->db->query("SELECT id FROM cobabarang WHERE nama = \"$nama\"");
return $id->row_array();
}
public function add_images($newImage) {
//$this->db->insert("cobagambar", $newImage);
$id = $newImage["barangid"]["id"];
$gambar = $newImage["gambar"];
$this->db->query("INSERT INTO cobagambar(barangid, gambar1) VALUES($id, \"$gambar\")");
}

Answer 1

there is an error here:
foreach($image as $img)
{
$barangImage = array(
"gambar" => $img,
"barangid" => $id
);
}
change the $barangImage to $barangImage[]
when you put the images into database i suggest that using json_encode($barangImage), and then json_decode($images-json-string) when you going to use the images.

There is something wrong with your foreach loop
foreach($image as $img) {
$barangImage = array(
"gambar" => $img //might be img['img'] I guess $img is again an array...you hvae to check that
"barangid" => $id //might be $img['id']check on this too..will be $img['id'] I guess
);
}
My guess is that $img is again an array with some keys. You really need to check on that And you can directly call the insert function in that foreach loop itself like this,
foreach($image as $img) {
$barangImage = array(
"gambar1" => $img['img'], //I guess $img is again an array...you hvae to check that
"barangid" => $img['id'] //check on this too..will be $img['id'] I guess
);
$id = $this->testModel->add_images($barangImage));
}
NOTE: The keys in your array barangImage must be column name in the table. i.e
gambar1 and barangid will be your column names. so you can directly use codeIgniter's active records.
Just change your add_images function
public function add_images($newImage) {
$this->db->insert("cobagambar", $newImage);
}
