getting field error about formr HOT 6 CLOSED

That's the code that you use. If it's not working for you, then please show your code.

I need code like this screenshot

from formr.

Ok, I think I understand what you want. Add this function to class.formr.php and see if it's what you're looking for

public function error($key)
{
    foreach ($this->errors as $k => $message) {
        if ($key == $k) {
            $this->_echo($message);
        }
    }
}

Then use it in your form like this

$form->text('first_name', 'First name');
$form->error('first_name');

$form->text('last_name', 'Last name');
$form->error('last_name');

Yeah u got me right 🙌, really appreciate and one more pls can unique validation be added, I mean to check data already exist in database field

from formr.

Cool, I'll add that to the next release.

Can you give me an example of what you mean by unique validation? Normally you'd just do if($database->result == $somevariable), so I'm unclear how you'd use Formr to validate a database result, especially since Formr doesn't work with databases.

from formr.

This is sample class

class UniqueRule extends Rule
{
protected $message = ":attribute :value has been used";

protected $fillableParams = ['table', 'column', 'except'];

protected $pdo;

public function __construct(PDO $pdo)
{
    $this->pdo = $pdo;
}

public function check($value): bool
{
    // make sure required parameters exists
    $this->requireParameters(['table', 'column']);

    // getting parameters
    $column = $this->parameter('column');
    $table = $this->parameter('table');
    $except = $this->parameter('except');

    if ($except AND $except == $value) {
        return true;
    }

    // do query
    $stmt = $this->pdo->prepare("select count(*) as count from `{$table}` where `{$column}` = :value");
    $stmt->bindParam(':value', $value);
    $stmt->execute();
    $data = $stmt->fetch(PDO::FETCH_ASSOC);

    // true for valid, false for invalid
    return intval($data['count']) === 0;
}

}

And this is the usage

$validation = $validator->validate($_POST, [
'email' => 'email|unique:users,email'
]);
