How to display an array of errors when working with redirect() in Codeigniter? - KalooDinaz - 12-05-2023
I created a form to add a product on Codeigniter. The form works fine, but I can't fully configure the validation.
The Products controller, which has the add_form() method, is responsible for processing the product addition form.
In this method, at the very beginning I check the validity of the fields.
PHP Code:
$validationRule = [
'name_product' => [
'label' => 'Product name',
'rules' => 'required|max_length[256]',
'errors' => [
'required' => "Field '{field}' required",
]
],
'price_product' => [
'label' => 'Price',
'rules' => 'required|is_natural',
'errors' => [
'is_natural' => "F Field '{field}' must be a number",
'required' => "Field '{field}' required",
]
],
];
$validation = \Config\Services::validation();
$validation->reset();
$validation->setRules($validationRule);
if (!$validation->run($dataQuery)) {
$arrErrors = $validation->getErrors();
return redirect()->back()->withInput()->with('errors', $arrErrors);
}
In general, everything works, but I can’t display a list of errors in the form view!
I don't understand how to display the data passed to the ->with('errors', $arrErrors) method
