Question

I retrieve an URL like below

http://localhost/codeigniter/?first=value_on_first_param&second=value_on_second_param

And at that URL I have code to retrieve the URL that has some GET parameters on URL

if( $first = $this->input->get( 'first' )
    && $second = $this->input->get( 'second' )
){

    echo 'first param: '.$first;
    echo '<br />';
    echo 'second param: '.$second;

}

Then I try to print the output of params that assigned to some variables

first param: 1
second param: value_on_second_param

As we see above, I have first param value to be 1 not value_on_first_param. Why? Am I doing something wrong here? Thanks.

Answer 1

Its because the assignment:

You do

$first = 
       $this->input->get( 'first' ) && 
$second = $this->input->get( 'second' ) 

is like

$first = 
      ( $this->input->get( 'first' ) && 
        $second = $this->input->get( 'second' )
      ) 

so the $first will get true value.

You have to use it:

if( ($first = $this->input->get( 'first' ))
    && ($second = $this->input->get( 'second' ) )
){

    echo 'first param: '.$first;
    echo '<br />';
    echo 'second param: '.$second;

}
