Quick question about Libraries.

Is there a way to pass variables to the Library other than through the constructor? I have vars in the class itself that I want to set dynamically from the controller. I am just getting started building my own libraries and thus am a little confused.

Thanks all!

Here is one approach.

Code:
$this->load->library('sample');

$this->sample->var1 = 'value1';

$this->sample->var2 = 'value2';

And then in the library $var2 would have value of 'value2'?

The following is how you'd access var2:

Code:
$this->var2

It would be an object variable.

Coolfactor:

I tried that. In the controller I put:

Code:
$this->load->library('Weather');

$this->weather->zp1 = '01810';

$d['weather_info']=$this->weather->get_weather();

In the library I put

Code:
class Weather

{

    var $zipcode = $this->zp1;                // Zipcode

And I am getting

Quote:Parse error: syntax error, unexpected T_VARIABLE in /home/cldev/public_html/includes/application/libraries/Weather.php on line 40

Line 40 is var $zipcode = $this->zp1;

Any ideas? Thanks.

You need to study up on object-oriented programming a bit more. Wink

In your controller, just assignn the "zipcode" directly:

Code:
$this->weather->zipcode = '01810';

No need to pass it through a different variable.

Thanks! Just starting to make libraries.
