如何在代码点火器中插入多个复选框值

Question

我需要在Codeigniter的复选框中插入多个值。如何在控制器中写入此内容。我尝试了很多，但没有插入值。

查看。Php

<div class="custom-file">
<input type="checkbox" name="size[]" value="Medium"> M 
<input type="checkbox" name="size[]" value="Large">L
<input type="checkbox" name="size[]" value="XL"> XL
</div>

型号

public function product_insert($data)
{
// grab user input
$this->db->insert('product', $data);
return $this->db->insert_id();
}

控制器

public function newProduct()
{
$data   = array();
$this->load->library('form_validation');
$this->load->library('image_lib');
$this->load->helper('file');
$this->load->helper('string');
// Load the model
$this->load->model('admin/product_model');
$this->load->model('admin/category_model');
$data['category']   = $this->category_model->active_category_listing();
// $data['brand']        = $this->product_model->brand_listing();

$this->form_validation->set_error_delimiters('<div class="alert alert-danger">', '</div>');
// Validating  Field
$this->form_validation->set_rules('product_title', 'Title', 'required');
if ($this->form_validation->run() == false) {
$this->load->view('admin/add_product', $data);
} 
//insert size checkboxes into database.
$sizeArray = $this->input->post('size');  // Array

$sizeString = implode(",", $sizeArray);    // String
else {
$config['upload_path'] = 'uploads/product_images/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = 10024;
$this->load->library('upload', $config);
// upload file to directory
$uploadedFile ='';
if ($this->upload->do_upload('product_img')) {
$uploadData = $this->upload->data();
$uploadedFile = $uploadData['file_name'];
$config['image_library'] = 'gd2';
$config['source_image'] = $uploadData['full_path'];
$config['new_image'] = 'uploads/product_images/thumb';
$config['create_thumb'] = false;
$config['maintain_ratio'] = TRUE;
$config['width']         = 311;
$config['height']       = 415;
$this->image_lib->initialize($config);
$this->load->library('image_lib', $config);
$this->image_lib->resize();

$data['success_msg'] = 'File has been uploaded successfully.';
} else {
$data['error_msg'] = $this->upload->display_errors();
}
// Setting values for tabel columns
$data = array(
'product_title' => $this->input->post('product_title'),
'product_description' => $this->input->post('product_description'),
'product_price' => $this->input->post('product_price'),
'product_discount' => $this->input->post('product_discount'),
'product_quantity' => $this->input->post('product_quantity'),
'sub_category_id' => $this->input->post('sub_category_id'),
'category_id' => $this->input->post('category_id'),
'product_status' => $this->input->post('product_status'),
'product_img' => $uploadedFile,
'product_key'   => random_string('alnum',8),
'product_cuttingprice'   => $this->input->post('product_cuttingprice'),
'size'=>$sizeString);
);
// Transfering data to Model
$prdID  = $this->product_model->product_insert($data);
$upImg      = $this->uploadAddtnlImages($prdID);    
$this->session->set_flashdata('msg', 'Product Added Successfully');
redirect('admin/product/listProduct/', 'refresh');
}

视图：-

您必须像这样将所有名称复选框作为array。

<div class="custom-file">
<input type="checkbox" name="size[]" value="Medium"> M 
<input type="checkbox" name="size[]" value="Large">L
<input type="checkbox" name="size[]" value="XL"> XL
</div>

控制器：-

public function newProduct()
{
$data   = array();
$this->load->library('form_validation');
$this->load->library('image_lib');
$this->load->helper('file');
$this->load->helper('string');
// Load the model
$this->load->model('admin/product_model');
$this->load->model('admin/category_model');
$data['category']   = $this->category_model->active_category_listing();
// $data['brand']    = $this->product_model->brand_listing();

$this->form_validation->set_error_delimiters('<div class="alert alert-danger">','</div>');
// Validating  Field
$this->form_validation->set_rules('product_title', 'Title', 'required');
if ($this->form_validation->run() == false) {
$this->load->view('admin/add_product', $data);
} 
else {
$config['upload_path'] = 'uploads/product_images/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = 10024;
$this->load->library('upload', $config);
// upload file to directory
$uploadedFile ='';
if ($this->upload->do_upload('product_img')) {
$uploadData = $this->upload->data();
$uploadedFile = $uploadData['file_name'];
$config['image_library'] = 'gd2';
$config['source_image'] = $uploadData['full_path'];
$config['new_image'] = 'uploads/product_images/thumb';
$config['create_thumb'] = false;
$config['maintain_ratio'] = TRUE;
$config['width']         = 311;
$config['height']       = 415;
$this->image_lib->initialize($config);
$this->load->library('image_lib', $config);
$this->image_lib->resize();

$data['success_msg'] = 'File has been uploaded successfully.';
} else {
$data['error_msg'] = $this->upload->display_errors();
}

//insert size checkboxes into database.
$sizeArray = $this->input->post('size');  // Array

$sizeString = implode(",", $sizeArray);    // String

// Setting values for tabel columns
$data = array(
'product_title' => $this->input->post('product_title'),
'product_description' => $this->input->post('product_description'),
'product_price' => $this->input->post('product_price'),
'product_discount' => $this->input->post('product_discount'),
'product_quantity' => $this->input->post('product_quantity'),
'sub_category_id' => $this->input->post('sub_category_id'),
'category_id' => $this->input->post('category_id'),
'product_status' => $this->input->post('product_status'),
'product_img' => $uploadedFile,
'product_key'   => random_string('alnum',8),
'product_cuttingprice'   => $this->input->post('product_cuttingprice'),
'size'=>$sizeString);
);
// Transfering data to Model
$prdID  = $this->product_model->product_insert($data);
$upImg      = $this->uploadAddtnlImages($prdID);    
$this->session->set_flashdata('msg', 'Product Added Successfully');
redirect('admin/product/listProduct/', 'refresh');
}
}

型号代码：-

public function product_insert($data)
{
// grab user input
$this->db->insert('product', $data);
return $this->db->insert_id();
}

注意：-有关implode()的更多信息。

implode()函数从数组的元素中返回一个字符串。
