Hai... I am new on PHP & Mysql,,,
please help me, I'm trying to follow this tutorial using xampp, and I get errors like this;
Warning: mysqli_real_escape_string () expects exactly 2 parameters, 1 given in C: \ xampp \ htdocs \ go \ edit.php on line 62
Deprecated: mysql_real_escape_string (): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in C: \ xampp \ htdocs \ go \ edit.php on line 63
and code
<?php
/*
EDIT.PHP
Allows user to edit specific entry in database
*/
// creates the edit record form
// since this form is used multiple times in this file, I have made it a function that is easily reusable
function renderForm($id, $date, $website1, $linkwebsite1, $website2, $linkwebsite2, $error)
{
?>
