我是ajax的新手，刚刚开始使用php。所以我在网上得到了一个ajax和php电子邮件代码似乎在第一次尝试时工作，接下来的几天突然不断返回错误信息，这是＆＃34;出了问题＆＃34;。如果我可以通过这个来源以及我如何解决它，请我感激不尽。非常感谢

$("#contactForm").validator().on("submit", function (event) {
    if (event.isDefaultPrevented()) {
        // handle the invalid form...
        formError();
        submitMSG(false, "Did you fill in the form properly?");
    } else {
        // everything looks good!
        event.preventDefault();
        submitForm();
    }
});


function submitForm(){
    // Initiate Variables With Form Content

Answer 1

你的逻辑是倒退的，在你的代码中，空$errorMSG是好的。

 if($errorMSG != ""){ // if NOT empty
echo "Something went wrong: ".$errorMSG; 
}else{
//good
}
