ตัวอย่าง Project เก่า ลองปรับแต่งดูนะครับ Random question and answer จาก subject
Code (PHP)
<form action="?Act=checkPoint" method="post">
<table class="table-full margin">
<tr>
<td><div class="green">แบบทดสอบ</div></td>
</tr>
<tr>
<td>
<?
$selectSub=mysql_query("SELECT * FROM subject"); // select แต่ละวิชาออกมาแสดง
while($sub=mysql_fetch_array($selectSub)){
$selectQue=mysql_query("SELECT * FROM question WHERE SubjectID='".$sub['SubjectID']."' ORDER BY rand() LIMIT 3"); // select คำถามแต่ละวิชา อ้างอิงจาก SubjectID แบบ Random limit 3
$no=0;
while($que=mysql_fetch_array($selectQue)){
$no++;
?>
<table class="table-full margin">
<tr>
<td width="17%" rowspan="2"><div class="no"><?=$no;?></div></td>
<td width="83%"><b>คำถาม :</b> <? echo $que['Question']; ?><input type="hidden" name="hdAnswerTrue[]" value="<?=$que['AnswerTrue'];?>" /></td>
</tr>
<tr>
<td>
<?
$noA=0;
$selectAns=mysql_query("SELECT * FROM answer WHERE QuestionID='".$que['QuestionID']."' ORDER BY rand()"); // select คำตอบ อ้างอิงจาก QuestionID แบบ Random
while($ans=mysql_fetch_array($selectAns)){
$noA++;
?>
<b>คำตอบที่ <?=$noA;?></b><input type="radio" id="Answer<?=$no;?>_<?=$noA;?>" name="Answer<?=$no;?>" value="<?=$ans['Answer'];?>" /><? echo $ans['Answer'];?><br>
<? } ?>
</td>
</tr>
<tr>
<td colspan="2"><div class="line"></div></td>
</tr>
</table>
<? }} ?>
</td>
</tr>
<tr>
<td><input type="submit" value="ส่งคำตอบ" onclick="return checkVal();" /></td>
</tr>
</table>
</form>
