我想在与用户使用PHP Redux输入数据的表单相同的页面上显示错误消息，但我不知道该怎么做。 我希望这些代码显示在registervistor.html中，而不是vistorprofile.php中。 有人可以帮我吗？

我建议您使用jquery表单验证：
http://jqueryvalidation.org/documentation/

在html文件中运行php内容，详细信息：
如何在html文件中运行php脚本？

但是您可以使用jquery / ajax表单提交，.html文件中的表单以及php文件中的所有验证：

$("#foo").submit(function(event){

    // Abort any pending request

    // setup some local variables

    // Let's select and cache all the fields
    var $inputs = $form.find("input, select, button, textarea");

    // Serialize the data in the form
    var serializedData = $form.serialize();

    // Let's disable the inputs for the duration of the Ajax request.
    // Note: we disable elements AFTER the form data has been serialized.
    // Disabled form elements will not be serialized.
    $inputs.prop("disabled", true);

    // Fire off the request to /form.php
    request = $.ajax({
        url:"/form.php",
        type:"post",
        data: serializedData
    });

    // Callback handler that will be called on success
    request.done(function (response, textStatus, jqXHR){
        // Log a message to the console
        console.log("Hooray, it worked!");
    });

    // Callback handler that will be called on failure
    request.fail(function (jqXHR, textStatus, errorThrown){
        // Log the error to the console
        console.error(
           "The following error occurred:"+
            textStatus, errorThrown
        );
    });

    // Callback handler that will be called regardless
    // if the request failed or succeeded
    request.always(function () {
        // Reenable the inputs
        $inputs.prop("disabled", false);
    });

    // Prevent default posting of form
    event.preventDefault();
});

// You can access the values posted by jQuery.ajax
