你知道我如何从多个复选框中获取值（html - ＆gt; php - ＆gt; email）？

Question

我已经从自由职业者引导程序模板修改了表单＆＃39;我添加了几个复选框。问题是，当我提交表单时，我没有从我的电子邮件中的复选框中获取值（其余的都没问题）。

以下是代码行：

HTML：

<form></form>

JS

 <div class="row control-group">
  <label id="areas">Areas of Interest:</label>
  <label class="checkbox"><input type="checkbox" name="areasofinterest[]" value="trade_show_events">trade show & events</label>
  <label class="checkbox"><input type="checkbox" name="areasofinterest[]" value="websites_optimiaztion">websites & optimization</label>
  <label class="checkbox"><input type="checkbox" name="areasofinterest[]" value="online_promotions">online promotions</label>
  <label class="checkbox"><input type="checkbox" name="areasofinterest[]" value="strategic_planning_branding">strategic planning & branding</label>
</div>

PHP

$(function() {

$("#contactForm input,#contactForm textarea").jqBootstrapValidation({
    preventSubmit: true,
    submitError: function($form, event, errors) {
        // additional error messages or events
    },
    submitSuccess: function($form, event) {
        // Prevent spam click and default submit behaviour
        $("#btnSubmit").attr("disabled", true);
        event.preventDefault();

        // get values from FORM
        var name = $("input#name").val();
        var companyname = $("input#companyname").val();
        var email = $("input#email").val();
        var phone = $("input#phone").val();
        var areasofinterest = $("input#areasofinterest").val();
        var message = $("textarea#message").val();
        var firstName = name; // For Success/Failure Message
        // Check for white space in name for Success/Fail message
        if (firstName.indexOf(' ') >= 0) {
            firstName = name.split(' ').slice(0, -1).join(' ');
        }
        $.ajax({
            url: "././mail/contact_me.php",
            type: "POST",
            data: {
                name: name,
                companyname: companyname,
                phone: phone,
                email: email,
                areasofinterest: areasofinterest,
                message: message
            },

我真的很感谢你的帮助:)。

提前致谢！
