javascript - 提交后未在 $_POST 中获取任何值

Question

我在 PHP 中提交页面时，本地 wamp 服务器遇到问题我正在使用 post 方法，提交表单后我没有在 $_POST 中获得任何值。我在网上搜索了很多，但没有得到任何好的解决方案。这是我的代码

<form name="form_modulesadd" id="form_modulesadd" method="POST" enctype="multipart/form-data" action="#" class="form-horizontal" >

        <div class="form-group">
            <label class="control-label col-md-2">Module Type<span class="required_mark">*</span></label>

                    <option value="1" <?php if($data['module_type'] == '1'){ echo 'selected'; } ?> >Video Module</option>

这是我的 javascript，我从中调用该页面

var options = {
    beforeSubmit: showRequest,
    success: showResponse,
    url: site_url + 'controllers/ajax_controller/modules-ajax-controller.php',
    type: "POST"
};
$('#form_modulesadd').submit(function() {
    $(this).ajaxSubmit(options);
    return false;
});

提交页面后，我没有在 $_POST 中获得任何值这段代码在服务器中运行良好。在本地环境中它给出了问题我正在使用 wamp 服务器。我已经尝试过 var_dump(),print_r() 但没有得到任何结果。任何帮助将不胜感激。

提前致谢。

Answer 1

在您的选项中，您应该指定要发送的数据。

var options = {
    beforeSubmit: showRequest,
    success: showResponse,
    url: site_url + 'controllers/ajax_controller/modules-ajax-controller.php',
    type: "POST",
    data: {data1: "your_data", data2: "your_data"}
};

然后，尝试:

<?php echo $_POST["data1"]; ?>

它将显示发送的数据，此处:your_data
