Help with Bitcoin Faucet script

Recommended Posts

So I found this script that can be used to make a Bitcoin Faucet, but have only one problem. I am getting the following error:

 

Warning: strtotime() expects parameter 1 to be string, array given in/home/***********public_html/*******************/faucet.php on line 27

 

Faucet.php is this: 

<?php
require_once('core.php');
echoHeader("Faucet");
if(isset($_POST['email']) && strlen($_POST['email']) > 0 || $_SESSION['email']){
	if(isset($_SESSION['email']) || filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)){

			$_SESSION['email'] = $mysqli->real_escape_string($_POST['email']);
		echo "<h2>Welcome</h2>";
		echo "<p>Your email is: " . htmlentities($_SESSION['email']) . "</p>";
	} else {

?>

Line 27 is this: 

		$lastClaim = strtotime($lastClaimQ->fetch_assoc());

So I am wondering what it is that is causing this. I must note that the page itself looks entirely normal, but that error is in the centre of the page. I am a noob when it comes to php. Thanks in advance!

 

PS: I downloaded the code here, in case you need to look at anything else. Or just ask me and I will copy paste my code :)

From their website:

 

Hacked together in a couple of hours. Code quality is horrifying.

LOL

 

$lastClaim = strtotime($lastClaimQ->fetch_assoc());
Is wrong what else is in the dispenses table? Also knowing this has been hacked together, not properly tested, you sure you wanna run this on your server? Edited by ignace

I have seen other people successfully use this code, so I assume it must be relatively secure. Although it is still a risk, heh.

 

Anyway, the only thing in the dispenses table when I click on it is: 

SELECT * 
FROM  `dispenses` 
LIMIT 0 , 30

Assuming that's what you mean. If you mean the data, there's nothing except one dispense where I was testing it.

Unless  I'm misreading this $lastClaimQ->fetch_assoc() will return array("dispensed"=>"whatever the value is"). 

if you just want the value you could use the current function to wrap fetch_assoc call

 

$lastClaim = strtotime(current($lastClaimQ->fetch_assoc()));
