มีปัญหาอยากสอบถามเกี่ยวกับการรับค่า จาก textbox มาแสดงเป็น log ครับ

<table width="650" border="1" cellspacing="2" cellpadding="2"align="center">
<tr>
<td width="91"><div align="center">ลำดับ</div></td>
<td width="91"><div align="center">รหัส</div></td>
<td width="200"><div align="center">ชื่อ-นามสกุล</div></td>
<td width="200"><div align="center">ปี/เดือน/วัน-เวลา</div></td>
</tr>

<?php 
$sql_show = "SELECT *FROM check_in ORDER BY test_in DESC LIMIT 0,5";
$result_show = mysql_query($sql_show) or die(mysql_error());
while($row_show = mysql_fetch_array($result_show))
{
	$sql="select * from user";
	$result1=mysql_query($sql, $link);
	$row_show1=mysql_fetch_array($result1);
	$user_fname=$row_show1["user_fname"];
	$user_lname=$row_show1["user_lname"];
	$test_in=$row_show["test_in"];
	$user_id_card=$row_show["user_id_card"];
	$datenow=$row_show["datenow"];
?>
<tr>
<td align='center'><font face='Angsana New' size='5' color='#000000'><? echo $test_in?></font></td>
<td align='center'><font face='Angsana New' size='5' color='#000000'><? echo $user_id_card?></font></td>
<td><div align="center">&nbsp;&nbsp;<font face='Angsana New' size='5' color='#000000'><? echo $tit_name?>&nbsp;<? echo $user_fname?>&nbsp;<? echo $user_lname?></font></td>
<td align='center'><font face='Angsana New' size='5' color='#000000'><? echo $datenow?></font></td>
