I need to set a message for the user, after validating a callback function, however, I do not enter anything referring. It has a generic message that fits the entire form, I want it by fields.
I tried form_validation->set_message , but it did not work.
I appreciate if anyone knows how to display a custom message from a callback function.
An example:
/** CHAMADA REGRA**/
$this->form_validation->set_rules('campo', 'Label Campo', 'required', ['nome_regra', [$Objeto, 'nome_funcao_valida']]],
['required' => 'Campo obrigatorio.']);
/** FUNCAO QUE VALIDA **/
function nome_funcao_valida($valor)
{
if(CONDICAO)
return true;
else
{
$this->form_validation->set_message('nome_regra', 'A {field} não confere');
return false;
}
}
