Call to undefined function (beginner)

[Ricky55]

Hi guys

PHP beginner.

I have just moved my site to a new server, the old server had an older version of PHP, 5. something and the new server has version 7.

I have a script that powers this page

https://www.jaybe.com/guarantee-register/

It just sends an email back to the user and also posts the form contents to a mysql database. A developer that I used to work with set this up for me a long time back.

Now when I run the script I get this error

Fatal error: Uncaught Error: Call to undefined function ereg() in /var/www/jaybe.com/public_html/_/scripts/guarantee.php:37 Stack trace: #0 {main} thrown in /var/www/jaybe.com/public_html/_/scripts/guarantee.php on line 37

The code from the script is here:-

<?php
	
	ini_set('display_errors', 1);
	ini_set('display_startup_errors', 1);
	error_reporting(E_ALL);

	$after = "/guarantee-register/thanks.php"; 
	$oops = "/guarantee-register/error.php";
	
if (isset($_POST['submit']) || isset($_POST['submit_x']) || $_SERVER['REQUEST_METHOD'] == "POST") {

    $exploits = "/(content-type|bcc:|cc:|document.cookie|onclick|onload|javascript|alert)/i";
    $profanity = "/(test)/i";
    $spamwords = "/(viagra|phentermine|tramadol|adipex|advai|alprazolam|ambien|ambian|amoxicillin|antivert|blackjack|backgammon|texas|holdem|poker|carisoprodol|ciara|ciprofloxacin|debt|dating|porn)/i";
    $bots = "/(Indy|Blaiz|Java|libwww-perl|Python|OutfoxBot|User-Agent|PycURL|AlphaServer)/i";

    if (preg_match($bots, $_SERVER['HTTP_USER_AGENT'])) {
        exit("<p>Known spam bots are not allowed.</p>");
    }
    foreach ($_POST as $key => $value) {
        $value = trim($value);

        if (empty($value)) {
        	if ($key != "email")  
        		{
            exit("<p>Please go back and complete the required fields.</p>");      
            	}
        } elseif (preg_match($exploits, $value)) {
            exit("<p>Exploits/malicious scripting attributes aren't allowed.</p>");
        } elseif (preg_match($profanity, $value) || preg_match($spamwords, $value)) {
            exit("<p>Please keep things clean, no naughty words!</p>");
        }

        $_POST[$key] = stripslashes(strip_tags($value));
    }

    if (!ereg("^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,6})$",strtolower($_POST['email']))) {
        exit("<p>How can we reply if you don't provide us with a valid email address?</p>");
    }

	conn();
	$sql = "INSERT INTO guarantee_reg (`gender`, `forename`, `surname`, `address`, `postcode`, `email`, `product`, `date_purchased`, `retailer`, `opt_in`)

	return $res;
}


function qry_row($sql)
{
	$res = qry($sql);
	$row = mysql_fetch_assoc($res);
	return $row;
}
?>

If anyone can shed any light I'd be very grateful.

Thanks

Once again the failure to RTFM is the cause of one's problem.

 

Look up ereg in the official PHP manual.  Sure I could be extremely helpful and give you the link (not!) except I believe you need to practice using the manual.

You have many more problems than that. The whole script is written with obsolete MySQL code that has been removed from PHP. This script will not work at all. The entire script needs to be re-written.
