Error - 

Fatal error: Uncaught TypeError: Unsupported operand types: string + int in /Users/shahed/Projects/samuraiconflict/attack.php:98 Stack trace: #0 /Users/shahed/.composer/vendor/laravel/valet/server.php(235): require() #1 {main} thrown in /Users/shahed/Projects/samuraiconflict/attack.php on line 98

 

 Line -       $ns = !isset($_GET['nextstep']) ? 1 : $_GET['nextstep'] + 2;

 

Tried searching for the fix but I couldn't seem to get anywhere, please help!

Post or send me your attack.php Just because the line says its line 98 doesn't always mean its that line that is the cause ??

However 

  

$ns = !isset($_GET['nextstep']) ? 1 : $_GET['nextstep'] + 2;

depending on whats above that line you could change to

 

  

if ( !$_GET['nextstep'] ) {
        $ns = 1;
     } else {
        $ns = $_GET['nextstep'] + 2;
     }

or

 

  

if(!$_GET['nextstep']) { $ns=1; } else { $ns=$_GET['nextstep']+2; }

 

But im just shooting in the dark here without seeing whats above or below

@Uridium - Thank you for helping me out

Post or send me your attack.php Just because the line says its line 98 doesn't always mean its that line that is the cause ??

However 

 

$ns = !isset($_GET['nextstep']) ? 1 : $_GET['nextstep'] + 2; 

$ns = !isset($_GET['nextstep']) ? 1 : $_GET['nextstep'] + 2;

depending on whats above that line you could change to

 

 

if ( !$_GET['nextstep'] ) {         $ns = 1;      } else {         $ns = $_GET['nextstep'] + 2;      } 

if ( !$_GET['nextstep'] ) {
        $ns = 1;
     } else {
        $ns = $_GET['nextstep'] + 2;
     }

or

 

 

if(!$_GET['nextstep']) { $ns=1; } else { $ns=$_GET['nextstep']+2; } 

if(!$_GET['nextstep']) { $ns=1; } else { $ns=$_GET['nextstep']+2; }

 

But im just shooting in the dark here without seeing whats above or below

it says the error within  Unsupported operand types: string + int

you need to make sure you are not mixing types and also wrap your operators correctly as could play a part in your errors.

this part is clearly the error, you could try using abs and intval to correct this. 

$_GET['nextstep'] + 2

Hello, I have fixed the issue. I forgot to echo out two statements on the links when attacking which was causing the error. However, now I am receiving the error only when the attacker is weaker than the person they are attacking. Can someone help me out on this as I have no clue on why it is throwing the error.

Check that the result of the guard / 1.5 is above 0 before using it as part of the equation 

<?php
// Check that the user's guard is above 0 and get the guard division result, otherwise it's 0
$guardResult = $youdata['guard'] > 0 ? $youdata['guard'] / 1.5 : 0;
// Begin the damage calculation
$dam = $enweps[$weptouse]['weapon'] * $odata['strength'];
// If we've got something to divide by ..
if ($guardResult > 0) {
    // .. divide it
    $dam /= $guardResult;
}
// Add the randomisation back in
$dam *= rand(8000, 12000) / 10000;
// And cast it to an integer
$dam = (int)$dam;


/**
 * Original line for reference
 * $dam = (int) (($enweps[$weptouse]['weapon'] * $odata['strength'] / ($youdata['guard'] / 1.5)) * (rand(8000, 12000) / 10000));
