POST无法用于文本框 [英] POST not working for textbox

我已经将表格数据显示在html表中，例如.net中的网格视图
它可以正常工作，但我无法从PHP中的表中访问数据.

Hi I have displayed my table data in a html table like grid view in .net
Its working but i coudln''t access the data from the table in PHP.

function jsfun(var1_name)
{
document.getElementById('htext1').value=var1_name;
var x="<?php pfun();?>";
alert(x);
return false;
}

<?php
function pfun()
{
	$a=$_POST['htext1'];// giving error as unterminated string or constant
		 
	echo($a);
}

<?php
if(isset($_POST['btnDisplay']))//button in my form design
	{
		
	  echo "<form method='post' action='";
	  echo $_SERVER['PHP_SELF'];
	  
	  echo "'/><table border='2' cellspacing='2' cellpadding='2'><tr><td><font face='Arial, Helvetica, sans-serif' color='#ff0000'>LoginId</font></td><td><font face='Arial, Helvetica, sans-serif' color='#ff0000'>UserName</font></td><td><font face='Arial, Helvetica, sans-serif' color='#ff0000'>Password</font></td><td><font face='Arial, Helvetica, sans-serif' color='#ff0000'>Modify</font></td></tr>";
	  $query=mysql_query("call prcLoginDisplay()");
	  
	  while($res=mysql_fetch_array($query))//getting data from database and display like gridview using html table
	  {
	  	echo "<tr><td><input type='text'  id='txtTLoginId' value='";
		echo $res['intLoginId'];//display in textbox inside html
		echo "' name='";
		echo "t".$res['intLoginId'];//creating textbox name to identify uniquely
		echo "'/></td><td><input type='text'  id='txtTLoginId' value='";
		echo $res['vchUserName'];	
		echo "' name='";
		echo "ut".$res['intLoginId'];
		echo "'/></td><td><input type='text'  id='txtTLoginId' value='";
		echo $res['vchPassword'];	
		echo "' name='";
		echo "pt".$res['intLoginId'];		
		echo "'/></td><td>";
		echo "<input type='button' value='submit' id='btnUpdate' name='";
		echo $res['intLoginId'];
		echo "'  önclick='jsfun(this.name)'/></td></tr>";//calling javascript function			
	  }
	  	echo "</table>";	  		
		echo "</form>";
		echo "<form method='post' action='";
		 echo $_SERVER['PHP_SELF'];
		echo "'><input type='text' id='htext1' name='htext1'  runat="server"/></form>";
	}
	
?>

在这里，我在html表的文本框中显示了数据，并为每个文本框和按钮生成了唯一的名称.每当用户单击网格中的按钮时，文本框内容将被复制到隐藏字段中.现在，我想在php中访问此隐藏字段.如何执行此操作?请帮助.
