Question

i having a function called website_check

function website_check($url){
if ($url !=""){     
    if (preg_match("#^https?://.+#", $url) and fopen($url,"r")){
        return TRUE;
    }else{
        $this->form_validation->set_message('Website url', 'The %s field is invalid');
        return FALSE;
    }       
}else{
    $this->form_validation->set_message('Website url', 'The %s field is required');
    return FALSE;
}

}

and i use this function as a custom code-igniter form validation function

$this->form_validation->set_rules('website', 'Website', 'callback_website_check');

i am using this function in every controller, so i want to add this function into codeigniters form validation class and use as a default validation function. is it possible to add your function to codeigniters form validation class,if it is how it can be done ?

Answer 1

Edit the file ‘system/libraries/Form_validation.php’ and insert this new function to the class “CI_Form_validation”.

function website_check($url){  
   if (preg_match("#^https?://.+#", $url) and fopen($url,"r")){
      return TRUE;
   }else{
      return FALSE;
   }       
}

And then edit the file ‘language/english/form_validation_lang.php’ and append this item:

$lang['website_check'] = "The %s field is invalid";

then use it as :

$this->form_validation->set_rules('website', 'Website', 'website_check');
