I created in codeigniter a helper for datatable that would return an html with a bootstrap icon.

Follows the function:

function trata_check($valor)
{
    $ci= & get_instance();

    if($valor=='S'){
                $html='<span class="glyphicon glyphicon-ok"></span>';
            }
            else{
                $html='<span class="glyphicon glyphicon-remove"></span>';
            }

    return $html;
}

The part that calls the function in the controller is this:

->edit_column('diario', trata_check('$1'),'diario')

The problem is that the comparison if($valor=='S') not being done, it is always returning false, but when I send only return the parameter passed it returns the right value, which can only be S or N.

  • The problem is how you are calling the helper, because what you are going through is the string '$1', not the value of the $1 variable.

  • To pass the value use double quotes, treat_check("$1")

  • Na can be the form that is passing the parameter inside the function? you are using simple quotes, therefore what will be passed would be the value $1 and not the variable value

  • The value is being passed yes, so much so that if I had it just return the value it returns normal, the problem is in the comparison. Anyway, I tried the suggestion and it wasn’t.

  • Where do you see the $1?

  • It is used to pass parameters in the edit_colum function of the CI.

The function call was being made wrong, the way the value was being passed, but it got some dirt in his memory, so he thought that S was different from the past value. Follow the correct way:

>edit_column('diario', '$1','trata_check(diario)')

Thank you all.

Give an isset on the variable sum, I think it will solve.

function trata_check($valor)
{
 $ci= & get_instance();

 if(isset($valor)=='S'){
  $html='<span class="glyphicon glyphicon-ok"></span>';
 }
 else{
  $html='<span class="glyphicon glyphicon-remove"></span>';
 }

 return $html;
