How to save image in folder using CodeIgniter? - php

Question

I am new to CodeIgniter. I want to know how to save an image in a folder. But I wrote the code like image name was stored in a table. But I want to store the image in a folder and retrieve image from the folder. Here I am using the code to store image name in table:
In Controller:
public function product()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('productname','Product Code','trim|required');
$this->form_validation->set_rules('productcode','Product Code','trim|required');
$this->form_validation->set_rules('productprice','Product Price','trim|required');
$this->form_validation->set_rules('quantity','Quantity','trim|required');
$this->form_validation->set_rules('uploadimage','Upload Image','trim_rquired');
if($this->form_validation->run()==FALSE)
{
$this->index();
}else
{
$data['query']=$this->main_model->product_db();
$this->load->view('query_view',$data);
}
}
In Model:
public function product_db()
{
$data=array(
'productname'=>$this->input->post('productname'),
'productcode'=>$this->input->post('productcode'),
'productprice'=>$this->input->post('productprice'),
'quantity'=>$this->input->post('quantity'),
'image'=>$this->input->post('uploadimage')
);
$query=$this->db->get("product");
if($query->num_rows())
{
$this->db->insert('product',$data);
$query=$this->db->get("product");
$this->session->set_userdata($data);
return $query->result();
}
return false;
}
In View:(form page)
<?php echo validation_errors('<p class="error">'); ?>
<?php echo form_open("main/product"); ?>
<p>
<label for="product_name">Product Name:</label>
<input type="text" id="productname" name="productname" value="<?php echo set_value('product_name'); ?>" />
</p>
<p>
<label for="ProductCode">Product Code</label>
<input type="text" id="productcode" name="productcode" value="<?php echo set_value('productcode'); ?>" />
</p>
<p>
<label for="productprice">Product Price:</label>
<input type="text" id="productprice" name="productprice" value="<?php echo set_value('productprice'); ?>" />
</p>
<p>
<label for="Quantity">Quantity:</label>
<select name="quantity" id="quantity" value="<?php echo set_value('quantity'); ?>" /><option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
</p>
<p>
<label for="Uploadimage">Upload Image:</label>
<input type="file" name="uploadimage" id="uploadimage" value="<?php echo set_value('quantity'); ?>" />
</p>
<p>
<input type="submit" class="greenButton" value="submit" />
</p>
<?php echo form_close();
?>
In View(query_view Page):
<?php
echo "<table border='2'>
<tr>
<th>productid</th><th>productname</th><th>productcode</th><th>productprice</th>
<th>quantity</th><th>image</th>
</tr>";
foreach($query as $r)
{
echo "<tr>";
echo "<td>".$r->productid."</td>"."<td>".$r->productname."</td>".
<td>".$r>productcode."</td>"."<td>".$r->productprice."</td>"."<td>"
.$r->quantity."</td>"." <td>".$r->image."</td>";
echo "</tr>";
}
echo "</table>";
echo "<br>";
?>

This is just a sample code of uploading an image:
<?php
$configUpload['upload_path'] = './uploads/'; #the folder placed in the root of project
$configUpload['allowed_types'] = 'gif|jpg|png|bmp|jpeg'; #allowed types description
$configUpload['max_size'] = '0'; #max size
$configUpload['max_width'] = '0'; #max width
$configUpload['max_height'] = '0'; #max height
$configUpload['encrypt_name'] = true; #encrypt name of the uploaded file
$this->load->library('upload', $configUpload); #init the upload class
if(!$this->upload->do_upload('uploadimage')){
$uploadedDetails = $this->upload->display_errors();
}else{
$uploadedDetails = $this->upload->data();
}
print_r($uploadedDetails);die;
?>

Answer 2

you are seeking this kind of code
$config['upload_path'] = './files'; //core folder (if you like upload to application folder use APPPATH)
$config['allowed_types'] = 'gif|jpg|png'; //allowed MIME types
$config['encrypt_name'] = TRUE; //creates uniuque filename this is mainly for security reason
$this->load->library('upload', $config);
if (!$this->upload->do_upload('picture_upload')) { //picture_upload is upload field name set in HTML eg. name="upload_field"
$error = array('error' => $this->upload->display_errors());
}else{
//print_r($this->upload->data()); // this is array of uploaded file consist of filename, filepath etc. print it out
$this->upload->data()['file_name']; // this is how you get for example "file name" of file
}
Please follow this guide http://ellislab.com/codeigniter/user-guide/libraries/file_uploading.html it has everything in it. If you need help with logic its pretty simple
form -> upload field -> button -> form sent -> check rules if file is OK -> upload file -> save data (filename, filepath...) in table.
