[PHP知识库]dedecms织梦自定义表单添加提交ip，时间，链接方法

先在自定义表单中添加新字段。
新字段用来引用用户提交表单的时间，IP地址，提交链接。
在dedemcs根目录的plus中点击diy.php
搜索：${$fieldinfo[0]} = addslashes(${$fieldinfo[0]}); 在 } 后添加代码：

					if($fieldinfo[0] == 'ip')
                      {${$fieldinfo[0]}=GetIP();
                     }
                    if($fieldinfo[0] == 'time')
                    {
                     ${$fieldinfo[0]}=date("Y-m-d H:i:s");
                   }
				   if($fieldinfo[0] == 'url')
					{
				${$fieldinfo[0]}=$_SERVER['HTTP_REFERER'];
					}

$fieldinfo[0]中的数值需和创建新字段名称一致。

再进入到调用自定义表单的位置：

	<input type='hidden' name='time' id='time'  placeholder=""  />
	<input type='hidden' name='ip' id='ip'  placeholder=""  />	
	<input type='hidden' name='url' id='url' placeholder="" />
	<script type="text/javascript">
			window.onload = function() {
			var nowDate = new Date();
			var str = nowDate.getFullYear() + "-" + (nowDate.getMonth() + 1) + "-" + nowDate.getDate() + " " + nowDate.getHours() + ":" + nowDate.getMinutes() + ":" + nowDate.getSeconds();
			document.getElementById("time").value = str;}
	</script>
	<script type="text/javascript">
			window.onload = function() {
			var nowDate = new Date();
			var str = nowDate.getFullYear() + "-" + (nowDate.getMonth() + 1) + "-" + nowDate.getDate() + " " + nowDate.getHours() + ":" + nowDate.getMinutes() + ":" + nowDate.getSeconds();
			document.getElementById("ip").value = str;}
	</script>
	<script type="text/javascript">
		  window.onload = function() {
			var nowDate = new Date();
			var str = nowDate.getFullYear() + "-" + (nowDate.getMonth() + 1) + "-" + nowDate.getDate() + " " + nowDate.getHours() + ":" + nowDate.getMinutes() + ":" + nowDate.getSeconds();
			document.getElementById("url").value = str;}
	</script>

type='hidden’的意思是隐藏域，设置完更新全站就可以了。
