我正在创建一个跟踪像素,并使用this answer作为起点。但是,在我尝试将数据插入数据库之前,一切正常。此时我得到500(内部服务器错误)。
这是我的代码:
<?php
$im=imagecreate(1,1);
$white=imagecolorallocate($im,255,255,255);
imagesetpixel($im,1,1,$white);
header("content-type:image/jpg");
imagejpeg($im);
imagedestroy($im);
$client = @$_SERVER['HTTP_CLIENT_IP'];
$forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
$remote = $_SERVER['REMOTE_ADDR'];
function getUserIP() {
$client = @$_SERVER['HTTP_CLIENT_IP'];
$forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
$remote = $_SERVER['REMOTE_ADDR'];
if(filter_var($client, FILTER_VALIDATE_IP)) {
$ip = $client;
} else if (filter_var($forward, FILTER_VALIDATE_IP)) {
$ip = $forward;
} else {
$ip = $remote;
}
return $ip;
}
$user_ip = getUserIP();
$ip_integer = ip2long($user_ip);
$web_url = 'myurl.com';
$sqlWebLeads = "INSERT INTO ip_details (ip_address, web_url)
VALUES ('$ip_integer','$web_url')";
$wpdb->query($sqlWebLeads);
?>
有什么想法吗?

它在wordpress网站上运行,因此
$wpdb->query
是一个全局函数,通常不需要定义。
这不是魔术,所以,如果你创建一个独立的php文件,它将不会有wordpress全局定义的对象,作为你的$wpdb
数据库链接。
您需要在页面中设置该对象才能使用它,请查看Using WPDB in standalone script?
$path = $_SERVER['DOCUMENT_ROOT']; include_once $path . '/wp-config.php'; include_once $path . '/wp-load.php'; include_once $path . '/wp-includes/wp-db.php'; include_once $path . '/wp-includes/pluggable.php'; // $wpdb is available, do stuff

问题(由@Blag正确指出)是$ wpdb-&gt;查询仅在wordpress框架内工作,即如果所有wordpress包含文件都被加载。所以我现在的解决方案是使用MySQLi函数创建一个新的独立数据库连接。我在下面发布了我的代码,供其他遇到相同问题的用户以及在wordpress中创建跟踪像素的工作代码。
感谢@Blag帮助我得到这个答案。

imagepng($im);
imagedestroy($im);

if ($conn->query($sql) === TRUE) { echo "New record created successfully";}
else { echo "Error: " . $sql . "<br>" . $conn->error;}
$conn->close();
