check value in $_POST variable

[eluser][email protected][/eluser]
I want to some idea to make code simplifly more than this
In the controller I have a code
if($this->input->post('name')!='')
{
$data = array(
'name' => $this->input->post('name'),
'number' => $this->session->userdata('number')
);
}
if($this->input->post('number')!='')
{
$data = array(
'name' => $this->session->userdata('name'),
'number' => $this->input->post('number'),

);
}
.....
when I have many index in array $_POST I must write if function more and more
Can anyone tell me to make code simplifly more than that to check entry value may by interation or anything I have a loose.
Thank you

You can use the ternary syntax for this.

Code:

$data = array(
  'name' => $this->input->post('name') != '' ? $this->input->post('name') $this->session->userdata('name'),
  'number' => $this->input->post('number') != '' ? $this->input->post('number') $this->session->userdata('number')            
);

I met some error with unexpected with T_VARIABLE

Phil's code got eaten by the code system. Between the calls to $this->input and $this->session there should be a colon (.

So: 'name' => $this->input->post('name') != '' ? $this->input->post('name') : $this->session->userdata('name')


I actually didn't know ternary syntax could be used in an array definition like this, which is a pretty cool.

Thank alot with you pretty cool code,
Actually, my code is duty I want to make clean code for do that, I think with array filter with loop but don't no much?
I use jeditable with controller and model,if I have more database fileds the code can be confuse and more line
Can people help me to design for do that?

People here seem to really despise IF ELSE control structures. I don't get it.
