不寫死任何東西，藉助jquery ajax提交dedecms自定義表單到後臺。

注意表單部分，此例只做為參考，實際專案中根據自己的情況酌情修改。

認真看下面例子中 紅色部分

<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" /><!-- 這是為了跟其他非ajax自定義表單不衝突 -->
    <div class="mail_rdd">
        <div class="mail_content">
            <table border="1" width="100%" class="mail_form">
            <tr>
                <td width="50">
                    姓名：
                </td>
                <td class="mail_input_bg1">
                    <input type="text" name="mail_name" id="mail_name" maxlength="20"/>
                </td>
            </tr>
            <tr>
                <td>
                    電話：
                </td>
                <td class="mail_input_bg1">
                    <input type="text" name="mail_phone" id="mail_phone" maxlength="20"/>
                </td>
            </tr>
            <tr style="height:240px">
                <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裡面的id
        success: function(data) {
            if(data=="success"){
                alert('傳送成功!');
            }else{
                alert('傳送失敗!');
            }
        }
    });
}
</script>

開啟/plus/diy.php 找到

showMsg($bkmsg,-1,0,3000);

改成

if($setup == 'ajax')
{
    echo "success";
    exit;
}
else
{
    showMsg($bkmsg,-1,0,3000);
}

如果是gbk編碼的童鞋，還要修改/plus/diy.php，解決亂碼問題

開啟/plus/diy.php 找到

$addvalue .= ", '".${$fieldinfo[0]}."'";

改成

$addvalue .= ", '".iconv( "UTF-8", "gb2312//IGNORE" , ${$fieldinfo[0]})."'";

另一種js $.post方法

var dataString = {
	'name':$("#name").val(),
	'tel':$("#tel").val(),
	'setup':'ajax',
	'action':'post',
	'diyid':1,
	'do':2,
	'dede_fields':'name,text;tel,text',
	'dede_fieldshash':'6b5fb808a4b9ea6d0603d983246a88a1',
};
$.post("/plus/diy.php",dataString,function(result){
	if(result=="1"){
		alert('傳送成功!');
		$('#diyform').reset();//重置form
	}else{
		alert('傳送失敗!');
	}
});
