刚建立一个网站表单，在单页面调用，表格调用出来了，但是无法提交内容

{php extract(dr_get_form_post_value('baoming'))}

<form action="" class="form-horizontal" method="post" name="myform" id="myform">

{$form}

<div class="fc-form-body">

{$myfield}

{$diyfield}

{$sysfield}

{if $is_post_code}

<div class="form-group">

<label class="control-label col-md-2">{dr_lang('验证码')}</label>

<div class="col-md-10">

<label>

<div class="form-recaptcha">

<div class="input-group">

<input type="text" class="form-control" name="code">

<div class="input-group-btn fc-code">

{dr_code(120, 35)}

</div>

</div>

</div>

</label>

</div>

</div>

{/if}

</div>

<div class="portlet-body form myfooter">

<div class="form-actions text-center">

<button type="button" onclick="dr_ajax_submit('{$post_url}', 'myform', '2000', '{$rt_url}')" class="btn green"> <i class="fa fa-save"></i> 提交内容</button>

</div>
