Question

I have a page with three forms.

I’d like to run different db calls corresponding to the button clicked.

I have a 2 lib functions. One validates, and the passes it to the _submit function…

How can I separate the _submit function based on which submit button is clicked?

Answer 1

You can either set up 3 different forms, each with its own action, or you can set different values for each submit button and take action based on the value of the submit variable.

View

<form name="my_form" action="some/action/validate/">
    <input type="submit" value="paypal" name="submit" />
    <input type="submit" value="promo" name="submit" />
    <input type="submit" value="employee" name="submit" />
</form>

Controller

function validate() {
    $my_action = $this->input->post('submit');
    if (my_action == 'paypal') {
        // Your logic
    }... etc
}
