Question

我的脚本有关于paypal IPN的问题。我使用PHPDesigner 7并且它在行上给出了一个红色错误（88），我真的试图看看是否有一个大括号丢失或者出现了什么问题但似乎没什么问题hoveren PHPDesigner正好在88行显示（语法错误出乎意料） T_ELSE）。

任何帮助表示感谢提前感谢。

这是我的代码：

    <?php

// PHP 4.1

// read the post from PayPal system and add 'cmd'

$req = 'cmd=_notify-validate';

$File = "errorss.txt"; 
 $Handle = fopen($File, 'w');
 $Data = "Entered the IPN script\n"; 
 fwrite($Handle, $Data); 

foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

 $Data = "Authentication Complete\n"; 
 fwrite($Handle, $Data); 

// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
$payment_gross = $_POST['payment_gross'];
$payment_fee = $_POST['payment_fee'];

 $Data = "Iten number:".$item_number." ".$payment_status."\n"; 
 fwrite($Handle, $Data); 

if (!$fp) {


 $Data = "Error\n"; 
 fwrite($Handle, $Data); 

} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {

 $Data = "Verified\n"; 
 fwrite($Handle, $Data); 
    if($payment_status == "Completed")
    {

 $Data = "Completed\n"; 
 fwrite($Handle, $Data); 

require_once('./dbconnect.php');



$kkql= mysql_query("SELECT * FROM orders WHERE w='$item_number'");



                if(mysql_num_rows($kkql) == 0)
                    {

                    exit(); 
                    } 

                                 mysql_query("UPDATE orders SET paid='1'");







                }
    }
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}

}
fclose ($fp);


} //This is also causing the error i think as it is red when it click on it, open and closed braces are displayed in green this one in red
 fclose($Handle); 
?>

Answer 1

删除第87行（85或86，如果您愿意）的右括号}。

这假设您需要else if而不是第{88}行if上的else if (strcmp ($res, "INVALID") == 0) {。

Answer 2

问题在于其他代码不适合代码的其余部分

else if (strcmp ($res, "INVALID") == 0) {
    // log for manual investigation
}

我认为你可能意味着这样的事情

<?php

// PHP 4.1

// read the post from PayPal system and add 'cmd'

$req = 'cmd=_notify-validate';

$File = "errorss.txt"; 
$Handle = fopen($File, 'w');
$Data = "Entered the IPN script\n"; 
fwrite($Handle, $Data); 

foreach ($_POST as $key => $value) {
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

$Data = "Authentication Complete\n"; 
fwrite($Handle, $Data); 

// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
$payment_gross = $_POST['payment_gross'];
$payment_fee = $_POST['payment_fee'];

$Data = "Iten number:".$item_number." ".$payment_status."\n"; 
fwrite($Handle, $Data); 

if (!$fp) {
 $Data = "Error\n"; 
 fwrite($Handle, $Data); 
} else {
    fputs ($fp, $header . $req);
    while (!feof($fp)) {
        $res = fgets ($fp, 1024);
        if (strcmp ($res, "VERIFIED") == 0) {
            $Data = "Verified\n"; 
            fwrite($Handle, $Data); 
            if($payment_status == "Completed")
            {
                $Data = "Completed\n"; 
                fwrite($Handle, $Data); 
                require_once('./dbconnect.php');
                $kkql= mysql_query("SELECT * FROM orders WHERE w='$item_number'");
                if(mysql_num_rows($kkql) == 0)
                {
                    exit(); 
                } 
                mysql_query("UPDATE orders SET paid='1'");
            }
        }
        if (strcmp ($res, "INVALID") == 0) {
            // log for manual investigation
        }
    }
}
    fclose ($fp);
} //This is also causing the error i think as it is red when it click on it, open and closed braces are displayed in green this one in red
fclose($Handle); 
?>

如果你很好地缩进你的代码，就会出现这样的错误。

根据我的评论，如果条件尝试将其放在}之后并删除最后一次结算{{1}，那么您的额外elseif和if条件没有父项}

我的脚本中出现此错误（语法错误意外T_ELSE）
