我不太确定为什么 if/else 对您不起作用，但可能发生的一件事是解释器在遇到 else 时忘记了 if 语句。解决此问题的一种方法是在条件块中回显您的 html 代码，如下所示：

<?php
    if ($mail_status) {
        echo "<script>";
        echo "var str = \"download\";";
        echo "document.write(str.link(\"http://www.myshedplans.com/12BY8SHED.pdf\"));";
        echo "</script>";
    }
    else {
        echo "<script language=\"javascript\" type=\"text/javascript\">";
        echo "alert('Message failed. Please, send an email to gordon@template-help.com');";
        echo "window.location = 'contact_page.html';";
        echo "</script>";
    }
?>
