织梦自定义表单教程：借助jquery ajax提交dedecms自定义表单到后台

不写死任何东西，借助jquery ajax提交dedecms自定义表单到后台。

注意表单部分，此例只做为参考，实际项目中根据自己的情况酌情修改。

<form action="/plus/diy.php" enctype="multipart/form-data" method="post" id="diyform">
<input type="hidden" name="action" value="post" />
<input type="hidden" name="diyid" value="1" />
<input type="hidden" name="do" value="2" />
<input type="hidden" name="dede_fields" value="mail_name,text;mail_phone;mail_content,multitext" />
<input type="hidden" name="dede_fieldshash" value="86d34525cf75f8652022f6446152028d" />
<input type="hidden" name="setup" value="ajax" /><!-- 这是为了跟其他非ajax自定义表单不冲突 -->
    <div class="mail_rdd">
        <div class="mail_content">
            <table border="1" width="100%" class="mail_form">
            <tr>
                <td >
                    姓名：
                </td>
                <td class="mail_input_bg1">
                    <input type="text" name="mail_name" id="mail_name" maxlength="20"/>
                </td>
            </tr>
            <tr>
                <td>
                    电话：
                </td>
                <td class="mail_input_bg1">
                    <input type="text" name="mail_phone" id="mail_phone" maxlength="20"/>
                </td>
            </tr>
            <tr >
                <td>
                    留言：
                </td>
                <td class="mail_input_bg3">
                    <textarea name="mail_content" id="mail_content"></textarea>
                </td>
            </tr>
            </table>
            <div class="mail_button_bar">
                <div class="mail_button confirm" onclick="send()">
                </div>
            </div>
        </div>
    </div>
</form>

js ajax方法部分

<script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.6.4/jquery.min.js"></script>
<script>
function send(){
    $.ajax({
        cache: true,
        type: "POST",
        url:"/plus/diy.php",
        data:$('#diyform').serialize(),// 你的form里面的id
        success: function(data) {
            var data = JSON.stringify(data);
            if(data['code']==1){
                alert(data.msg);
            }else{
                alert('发送失败!');
            }
        }
    });
}
</script>

打开/plus/diy.php 找到

showmsg($bkmsg, $goto);

改成

if($setup == 'ajax')
{
    $data = array('code'=>'1','msg' =>'提交成功！');
    echo json_encode($data);
}
else
{
    showmsg($bkmsg, $goto);
}
