</div>
<?php echo form_close(); ?>
this is my jquery code for ADD PRODUCT button.
<script type="text/javascript">
$('#fill').click(function(event){
var product_name = $('#product_name').val();
var image = $('#user_file').val();
var cat = $('#cat').val();
var product_description = $('#product_description').val();
if(product_name.length == 0)
{
$('#pnerror').show();
}
if(image.length == 0)
{
$('#imgerror').show();
}
if(cat == 0)
{
$('#caterror').show();
}
if(product_description.length == 0)
{
$('#pderror').show();
}
else if(product_name.length != 0 && image.length != 0 && cat != 0 && product_description.length != 0)
{
var $target = $( event.target );
$target.closest("form").submit();
}
});
</script>
this is my SUBMIT button
<script type="text/javascript">
$('#go').click(function(event){
var product_name = $('#product_name').val();
var user_file = $('#user_file').val();
var cat = $('#cat').val();
var product_description = $('#product_description').val();
if(product_name.length == 0)
{
$('#pnerror').show();
}
if(user_file.length == 0)
{
$('#imgerror').show();
}
if(cat == 0)
{
$('#caterror').show();
}
if(product_description.length == 0)
{
$('#pderror').show();
}
else if(product_name.length != 0 && user_file.length != 0 && cat != 0 && product_description.length != 0)
{
var $target = $( event.target );
$target.closest("form").submit();
}
});
</script>
This is my controller code:
public function submit()
{
print_r($_POST);
if($this->input->post('go'))
{
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 2048;
$config['max_height'] = 1024;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if ($this->upload->do_upload('user_file'))
{
$data = array('prod_data' => $this->upload->data());
$user_file = $data['prod_data']['raw_name']."".$data['prod_data']['file_ext'];
$id = $this->session->userdata['record']['id'];
$com_id = $this->session->userdata['record']['com_id'];
$sam = array(
'title' => $this->input->post('product_name'),
'type' => 'product'
);
$this->load->model('registermodel');
$chk = $this->registermodel->insertsam($sam);
if ($chk == TRUE)
{
$id = $this->registermodel->getsampleid();
$data = array(
'product_name' => $this->input->post('product_name'),
'image' => 'images/'.$user_file,
'product_description' => $this->input->post('product_description'),
'cat_id' => $this->input->post('cat'),
'com_id' => $com_id,
'id' => $id
);
$check = $this->registermodel->insertproduct($data);
if($check == TRUE)
{
echo "<script>
alert('Data Submitted Succesfully');
</script>";
redirect('/homecontroller');
}
else
{
echo "Value insertion Failed";
}
}
}
else
{
$error = array('error' => $this->upload->display_errors());
print_r($error);
}
}
else if($this->input->post('fill'))
{
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 2048;
$config['max_height'] = 1024;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if ($this->upload->do_upload('user_file'))
{
$data = array('prod_data' => $this->upload->data());
$user_file = $data['prod_data']['raw_name']."".$data['prod_data']['file_ext'];
$id = $this->session->userdata['record']['id'];
$com_id = $this->session->userdata['record']['com_id'];
$sam = array(
'title' => $this->input->post('product_name'),
'type' => 'product'
);
$this->load->model('registermodel');
$chk = $this->registermodel->insertsam($sam);
if ($chk == TRUE)
{
$id = $this->registermodel->getsampleid();
$data = array(
'product_name' => $this->input->post('product_name'),
'image' => 'images/'.$user_file,
'product_description' => $this->input->post('product_description'),
'cat_id' => $this->input->post('cat'),
'com_id' => $com_id,
'id' => $id
);
$check = $this->registermodel->insertproduct($data);
if($check == TRUE)
{
echo "<script>
alert('Product added Succesfully');
</script>";
$data['category'] = $this->linkmodel->get_category();
$data['cat'] = $this->registermodel->get_category();
$this->load->view('itemview',$data);
}
else
{
echo "Value insertion Failed";
}
}
}
else
{
$error = array('error' => $this->upload->display_errors());
print_r($error);
}
}
}
print_r($_POST);
this returns only this :
Array ( [product_name] => Multifunction Printer Machine [cat] => 82 [product_description] => Approx Price: Rs 80,000 / Piece)
not return ADD PRODUCT OR SUBMIT button name, please anyone tell me what i am doing wrong ?

Answer 1

You may have to use <input type="submit" ...> instead of <button ...>. It should append buttons' name and value to $_POST.

Answer 2

Add input hidden field in your form and set different value in each JavaScript code.
<?php echo form_open_multipart('itemcontroller/submit'); ?>
<!-- your existing code --->
<input type="hidden" name="submit_type" id="submit_type" value="" />
<?php echo form_close(); ?>
JavaScript code Modification
<script type="text/javascript">
$('#go').click(function(event){
<!-- your existing code --->
$('#submit_type').val('SUBMIT');
var $target = $( event.target );
$target.closest("form").submit();
}
});
</script>
<script type="text/javascript">
$('#fill').click(function(event){
<!-- your existing code --->
$('#submit_type').val('ADD PRODUCT');
var $target = $( event.target );
$target.closest("form").submit();
}
});
</script>
