function products_edit($product_id) {
$this->load->helper('form');
$this->load->helper('html');
$this->load->library('form_validation');
$this->load->model('products_model');
$data=$this->products_model->general();
$category['categories']=$this->products_model->get_category();
$product = $this->products_model->get_product($product_id);
$this->data['title'] = 'Edit Product';
//validate form input
$this->form_validation->set_rules('name', 'Product name', 'required|xss_clean');
$this->form_validation->set_rules('description', 'Product Description', 'required|xss_clean');
$this->form_validation->set_rules('category', 'Category', 'required|xss_clean');
//$this->form_validation->set_rules('extras', 'Extras', 'required|xss_clean');
$this->form_validation->set_rules('price', 'Price', 'required|xss_clean');
$this->form_validation->set_rules('is_featured', 'Is Featured', 'required|xss_clean');
$this->form_validation->set_rules('prorder', 'prorder', 'required|xss_clean');
if (isset($_POST) && !empty($_POST)) {
$data = array(
'product_name'=> $this->input->post('name'),
'product_desc'=> $this->input->post('description'),
'product_category' => $this->input->post('category'),
'extras' => $this->input->post('extras'),
'price' => $this->input->post('price'),
'is_featured' => $this->input->post('is_featured'),
'prorder' => $this->input->post('prorder'),
);
if ($this->form_validation->run() === true) {
$this->products_model->updateproducts($product_id, $data);
$this->session->set_flashdata('message', "<p>Product updated successfully.</p>");
redirect('products_controller/products_edit/'.$product_id);
}
}
$this->data['message'] = (validation_errors() ? validation_errors() : $this->session->flashdata('message'));
$this->data['product'] = $product;
//display the edit product form
$this->data['name'] = array(
'name' => 'name',
'id' => 'name',
'type' => 'text',
'style' => 'width:300px;',
'value' => $this->form_validation->set_value('name', $product['product_name']),
);
$this->data['description'] = array(
'name' => 'description',
'id' => 'description',
'type' => 'text',
'cols' => 60,
'rows' => 5,
'value' => $this->form_validation->set_value('description', $product['product_desc']),
);
$cat=array();
$test = array();
for($i=0;$i<=3;$i++) {
$test[$i] = array($category['categories'][$i] => $category['categories'][$i]);
}
$this->data['category'] = $test;
$this->data['extras'] = array(
'name' => 'extras',
'id' => 'extras',
'type' => 'text',
'style' => 'width:250px;',
'value' => $this->form_validation->set_value('extras', $product['extras']),
);
$this->data['price'] = array(
'name' => 'price',
'id' => 'picture',
'type' => 'text',
'style' => 'width:250px;',
'value' => $this->form_validation->set_value('price', $product['price']),
);
$this->data['is_featured'] = array(
'name' => 'is_featured',
'id' => 'is_featured',
'type' => 'text',
'style' => 'width:250px;',
'value' => $this->form_validation->set_value('is_featured', $product['is_featured']),
);
$this->data['prorder'] = array(
'name' => 'prorder',
'id' => 'prorder',
'type' => 'text',
'style' => 'width:250px;',
'value' => $this->form_validation->set_value('prorder', $product['prorder']),
);
$this->load->view('products_edit', $this->data);
}
The error occurs in this line.
for($i=0;$i<=3;$i++) {
$test[$i] = array($category['categories'][$i] => $category['categories'][$i]);
}
The error is due to $i in the test array. If I remove it, causing an error. I don't have solution for this error.

Answer 1

Is there a particular reason why you're using a for loop to build your categories dropdown list?
The $test array needs to look something like this:
$test = array(
1 => 'Pizza',
2 => 'Sandwich',
3 => 'Dessert',
4 => 'Salad'
);
Where the key is the associated id to the category and the value is the category name. At the minute you are loading both the key and value of the array with the whole category (based on it's index).
If you are wanting to pull out all the categories into a dropdown box, I would suggest something similar to the below, as this would allow you to add additional categories in future and them appear in the dropdown box:
foreach($category['categories'] as $category) {
$test[$category['id']] = $category['name'];
}
$this->data['category'] = $test;
This would require the categories (which I assume are being pulled out of a database table?) to have an id and name field.
Hope that helps...
