  • If you are redirected after the error occurs, you lose the error message. The code you've written above (reading from `mysqli_error`) might be alright, but you should remove the redirect first – Nico Haase Aug 02 '18 at 06:07

    Instead of explaining your code, you should add all the relevant code into the question. We need to see the context of the above line. – M. Eriksson Aug 02 '18 at 06:11

If you want to view Error then you can do many ways:

1.) You can do it from PHP.INI

display_errors = on

2.) You can do it from error_reporting(1);

<?php
// Turn off error reporting
error_reporting(1);

// Report runtime errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Report all errors
error_reporting(E_ALL);

// Same as error_reporting(E_ALL);
ini_set("error_reporting", E_ALL);

// Report all errors except E_NOTICE
error_reporting(E_ALL & ~E_NOTICE);
?

3.) You can do it from ini_set('display_errors', 1);

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Set this in index.php

first You should modify your php.ini with this line:

display_errors = on

and you can also Dumping Variables Before Send to db For debug

var_dump($yourvar);
die();
