Question

At this present point in time I have some code that does the following:

I can edit and I can add a house sale that uploads/edits one image for this particular house and then during the process a thumbnail is created and then the original file name and the thumbnail name is saved to database fields called imagename and imagethumb.

(Note: Add and Edit a seprate pages)

What my idea is:

I will create another page that has the name of the houses fed into a dropdown menu so when one is selected and images are selected they will upload.

What my issue is:

1. I am getting myself confused as to what would be the best way to modify my database to enable this change.

2. How would I modify my php code to handle more then one file (How do I handle multiple images and then pass the image for uploading resizing etc ) What is the best option? – within my given idea?

3. Could I have an example of what I should do so I can work off this.

I have included the model view and controller (As an Example) of my Add Sale but I will also need to edit a image for the respective sale.

Model:

class Sales_model extends CI_Model
{

    function __construct() {
            parent::__construct();
    }

    function getSalesPage($id = NULL) {

        $query = $this->db->get_where('sales', array('id' => $id), 1);
        if($query->num_rows() == 1) return $query->row();

    } # End getSalesPage

    function getSalesPages($id = NULL) { // $id does nothing
        $query = $this->db->get('sales');
        if($query->num_rows() > 0) return $query->result();

    } # End getSalesPages

    function getSalesContent($id = NULL) {
        $this->db->where('id', $id);
        $query = $this->db->get('sales', 1);

        if($query->num_rows() > 0) {
            $row = $query->result_array();
            return $row;
        }else{
            return FALSE;
        } # End IF
    } # End getSalesContent


    function addSale($data = NULL) {
        $this->db->insert('sales', $data);
        return TRUE;
    } # End Add Sale    

    function updateSale($id, $content) { //Content id from being passed

        $this->db->where('id', $id);  // selecting the $id to update
        $update = $this->db->get('sales'); // What does $update = well it = get the db sales
        $row = $update->row_array(); // what does $row mean = well it gets the row as an array

        if($update->num_rows() > 0) {

            if(isset($content['imagename']) && isset($content['thumbname'])) {

            #lets delete the image
            unlink("/includes/uploads/gallery/".$row['imagename']);
            #lets delete the thumb.
            unlink("/includes/uploads/gallery/thumbs/".$row['thumbname']);
        }
                $this->db->where('id', $id);
                if($this->db->update('sales', $content))
                {

                    return TRUE;
                }
                else
                {
                    return FALSE;
                }
            } # End IF
    } # End Update

    function deleteSale($id){

        $this->db->where('id', $id);
        $q = $this->db->get('sales');
        $row = $q->row_array();

        if ($q->num_rows() > 0){
            //delete from the database
            $this->db->where('id', $id); 
            $this->db->delete('sales');

            //lets delete the image
            unlink("includes/uploads/sales/".$row['imagename']);
            //lets delete the thumb.
            unlink("includes/uploads/sales/thumbs/".$row['thumbname']);
        }//END if num_rows
    }//END function deleteSale($id)
} # End Model

Answer 1

For handling dropdown, i think its easy one. But related multi upload stuff, you can use something like…

in your view

<?php echo form_label('Image: ','userfile1');?>
<?php echo form_upload('userfile1');?>
<?php echo form_label('Image: ','userfile2');?>
<?php echo form_upload('userfile2');?>
<!-- and so on -->
<span class="small">Required Field - 1MB Max Size</span>

Then in your controller, you can do this way

//Set File Settings 
$config['upload_path'] = 'includes/uploads/sales/'; 
$config['allowed_types'] = 'jpg|png'; 
$config['remove_spaces'] = TRUE;
$config['overwrite'] = TRUE;
$config['max_size'] = '1024';
$config['max_width'] = '1024'; 
$config['max_height'] = '768'; 

$this->load->library('upload', $config);

// Validate files for upload section...
$success = array();
$errors = array();
$updload_files = array(
        'userfile1' => $_FILES['userfile1'],
        'userfile2' => $_FILES['userfile2'],
        // You can add more
        );

foreach($updload_files as $field => $updload_file)
{
    // Only process submitted file
    if($updload_file['error'] == 0)
    {
       // If there is an error, save it to error var
       if( ! $this->upload->do_upload($field) )
       {
           $errors[] = 'Failed to upload '.$field;  
       }

       // Use this to get the new file info if you need to insert it in a database
       $success[] = array( 'Success to upload '.$field => $this->upload->data());
    } 
    else 
    {
       $errors[] = $field . ' contain no data';  
    }
}
// Heres you could gettin know whats happen
var_dump($errors);
var_dump($success);
