Error Call to Undefined Function mysqli_num_roms

Question

You’re making a mistake

Fatal error: Call to Undefined Function mysqli_num_roms()

I tried to fix it, but I couldn’t.

<?php

  require_once '../includes/configuration.php';

  $userName = $_POST["user-name"];
  $userPass = $_POST["user-pass"];

  $SQL = mysqli_query($con, "SELECT Usuario, Senha FROM administradores WHERE Usuario='$userName' AND Senha='$userPass' ");

  if (mysqli_num_roms($SQL) != 0){

      echo "logado";

  }else{

      echo "Login incorreto";

  }

?>

Answer 1

mysqli_num_roms does not exist, in English lines is rows, so if you want to take the number of lines use:

  if (mysqli_num_rows($SQL) != 0) {
      echo "logado";
  } else {
      echo "Login incorreto";
  }

Always read the documentation:

• http://php.net/manual/en/mysqli-result.num-rows.php
