form_validation doesn't show errors - vertisan - 02-13-2015 Hi! I have problem with Form Validation from CI 3.0 RC2. I have method in controller: PHP Code: public function dodaj() and view with: PHP Code: echo validation_errors(); RE: form_validation doesn't show errors - RobertSF - 02-13-2015 Everything looks ok, but here are some ideas. Are the set_rules statements executing? Check with an echo statement. Does the run() statement really return TRUE? Check with an echo statement. Try the rules with only 'required' and see if anything changes. RE: form_validation doesn't show errors - Narf - 02-13-2015 My guess is that you're submitting an empty form, which also means an empty $_POST and with your code - even the rules aren't set under that condition.

What won't echo anything either ... echo prints strings and CI_Form_validation::run() returns a boolean. Any time you cast a boolean to string (in this case, there's an implicit cast), it will become an empty string. var_dump() should help. RE: form_validation doesn't show errors - RobertSF - 02-14-2015 var_dump is definitely the way to go. But just to clarify, only FALSE results in an empty string. Echoing TRUE outputs 1 to the screen. Still, using var_dump is better than using echo, no doubt about it. RE: form_validation doesn't show errors - Narf - 02-14-2015 Hmm ... seems that you are correct. Quite weird, but true - echoing TRUE does result in 1 being printed. Anyway, enough of that - sorry for the noise. RE: form_validation doesn't show errors - RobertSF - 02-14-2015 Yes, but your general advice was still correct -- use var_dump instead of echo. |
