WordPress PHP服务器脚本发送电子邮件

Question

I am trying to get a server script to use wp_mail() and send an email to a user. I am doing this as part of a password reset routine, and calling the script with Ajax from the user's side.

I am getting the following error from my server script:

Fatal error: Call to undefined function wp_mail() in /var/www/abc-php/pwd.php on line 57

I cannot seem to find an answer to my question, so maybe I am asking incorrectly. Is what I am doing possible?

My server script (pwd.php) contains:

<?php

    $setFromId = "info@abc.com.au";
    $setFromName = "Info @ abc";
    $replyToId = "info@abc.com.au";
    $replyToName = "Info @ abc";

    $sendToEmail = base64_decode($_GET["ste"]);   //the URL in AJAX call contains base64 encoded data
    $resetPwd = base64_decode($_GET["rp"]);
    $resetSalt = base64_decode($_GET["rs"]);
    $param = $_GET["var"];

    $username = "xxxxxxxxx"; 
    $password = "xxxxxxxx";   
    $host = "localhost";
    $database = "xxxxxxxxx";
    $con = mysqli_connect($host, $username, $password, $database);

    // Check connection
    if (mysqli_connect_errno($con)) {
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    } else {
        switch ($param) {
            case "PWDRES":                                              // Query 1: Current Logged In Partner Details 
                $mysqli = new mysqli($host, $username, $password, $database);
                if (mysqli_connect_errno()) {
                    echo '<p>Unable to connect to the server at this time to update and send password. Please contact SMA for help or try again.</p>';
                } else {

                    $myquery = "UPDATE abc_users
                                SET `password` = SHA2('" . $resetPwd . $resetSalt . "', 512),
                                    `salt_value` = SHA2('" . $resetSalt . "', 512)
                                WHERE email_user_id = '" . $sendToEmail . "'";

                    mysqli_query($mysqli, $myquery);

                    if($mysqli->affected_rows >= 1) {

                        $headers = 'Reply-To: <' . $replyToName . '> ' . $replyToId;
                        $subject = "Password Reset - Confidential";
                        $body = "Subject: " . $subject . "<br/><br/>Your new password is: <br/><strong>" . $resetPwd . "</strong><br/><br/>Please ensure you reset this password next time you log in.";                        
                        $mail = wp_mail($sendToEmail, $subject, $body, $headers);
                        echo "Password was successfully reset and sent to " . $sendToEmail;

                    } else if($mysqli->affected_rows == 0) {
                        echo "No user id row was updated in the process of resetting password. Please try again.";
                    } else if($mysqli->affected_rows < 0) {
                        echo "There was an SQL error updating the user id password table. Please contact SMA for help.";
                    };
                };
            break;

                    case "OTHER1"
                    etc, etc, etc...
        default;

        };
    };

    unset($con);    
    unset($myquery); 
    unset($mysqli); 

?>

Any help is appreciated.

Answer 1

You need to include wp-load.php in your file....

Just put this in top of your file.

require_once( dirname(__FILE__) . '/wp-load.php' );

Answer 2

The problem is you are not including Wordpress, so you are not using it at all (and it isn't including its libraries).

Plus, this is unrelated to the question, but you have a weakness in your code : Any users can define the recipient of the email.
