如何在while循环中获取记录 [英] How to get record in while loop
本文介绍了如何在while循环中获取记录的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
producttable：
id | mid | pid | owgh | nwgh |
1 3 12 1.5 0.6
2 3 12 1.5 0.3
3 3 14 0.6 0.4
4 3 15 1.2 1.1
5 4 16 1.5 1.0
6 4 17 2.4 1.2
7 3 19 3.0 1.4
8 3 19 3.0 1.2
我需要在while循环中以低于结果：按照mysql查询
$ sql =SELECT pid，owgh，nwgh from produttable
WHERE mid = 3;
结果我希望如下：
产品ID |旧重量|新体重
---------------------------------------
12 1.5 0.6
12 1.5 0.3
总计：3.0 0.9
------------------------- -------
14 0.6 0.4
总计：0.6 0.4
-------------------- ------------
15 1.2 1.1
总计：1.2 1.1
--------------- -----------------
19 3.0 1.4
19 3.0 1.2
总计：6.0 2.6
$ query = mysql_query（$ sql）;
echo< table>
< tr>
< td>产品ID< / td>
< td>旧权重< / td>
< td>新怀特< / td>
< / tr> ;
;
while（$ row = mysql_fetch_array（$ query））{
echo< tr>;
echo< td>。$ row ['pid']。< / td>;
echo< td>。$ row ['owgh']。< / td>;
echo< td>。$ row ['nwgh']。< / td>;
回声< / tr>;
echo< tr>< td> -----< / td>
< td> Tot：< / td>
< td>< TD>< / TR>中;
}
回显
< / table>;
但是我得到的结果如下
产品ID |旧重量|新体重
---------------------------------------
12 1.5 0.6
-------------- Tot
12 1.5 0.3
--------------- Tot
14 0.6 0.4
---------------小费
15 1.2 1.1
-------------- -Tot
19 3.0 1.4
--------------- Tot
19 3.0 1.2
我不想要，我想要如下：
产品ID |旧重量|新体重
---------------------------------------
12 1.5 0.6
12 1.5 0.3
总计：3.0 0.9
------------------------- -------
14 0.6 0.4
总计：0.6 0.4
-------------------- ------------
15 1.2 1.1
总计：1.2 1.1
--------------- -----------------
19 3.0 1.4
19 3.0 1.2
总计：6.0 2.6
更新日期：30/3/2015
我可以得到低于结果，每个的总和
产品Id |旧重量|新体重
---------------------------------------
12 1.5 0.6
12 1.5 0.3
总计：3.0 0.9
------------------------- -------
14 0.6 0.4
总计：0.6 0.4
-------------------- ------------
15 1.2 1.1
总计：1.2 1.1
--------------- -----------------
19 3.0 1.4
19 3.0 1.2
总计：6.0 2.6
--- --------------------------------
GRAND TOTAL = 6.3 5
OR
产品ID |旧重量|新体重
---------------------------------------
12 1.5 0.6
1.5 0.3
总计：3.0 0.9
-------------------------- ------
14 0.6 0.4
总计：0.6 0.4
--------------------- -----------
15 1.2 1.1
总计：1.2 1.1
---------------- ----------------
19 3.0 1.4
3.0 1.2
总计：6.0 2.6
----- ------------------------------
GRAND TOTAL = 6.3 5
请注意：旧重量值具有重复性，当单一价值获得总值时，重量减少
<因为产品编号为12，因此19次出现两次，因此会显示一次其resp值。
请帮助我，如果我在HTML tr td格式中出错，请相应ct我，它不需要在同一个表tr，td ..我只想我的结果以上述格式解决方案试试这
$ oldsubtotal = 0;
$ newsubtotal = 0;
$ olsgrandtotal = 0;
$ newgrandtotal = 0;
while（$ row = mysql_fetch_array（$ query））{
if（isset（$ prev）&&（$ prev！= $ row ['pid']））{
echo< tr>< td style ='text-align：right'> Total< / td>< td> ;. $ oldsubtotal。< / td>< td>。 $ newsubtotal。 < / TD>< / TR> 中
echo< tr>< td colspan =3> -----< / td>< / tr>;
$ oldsubtotal = 0;
$ newsubtotal = 0;
}
echo< tr>;
echo< td>。$ row ['pid']。< / td>;
echo< td>。$ row ['owgh']。< / td>;
echo< td>。$ row ['nwgh']。< / td>;
回声< / tr>;
$ oldsubtotal + = $ row ['owgh'];
$ newsubtotal + = $ row ['nwgh'];
$ olsgrandtotal + = $ row ['owgh'];
$ newgrandtotal + = $ row ['nwgh'];
$ prev = $ row ['pid'];
}
echo< tr>< td style ='text-align：right'> Grand Total< / td>< td>。$ olsgrandtotal。< / td> < TD>中$ newgrandtotal。 < / TD> 中
producttable :
id | mid | pid | owgh | nwgh |
1 3 12 1.5 0.6
2 3 12 1.5 0.3
3 3 14 0.6 0.4
4 3 15 1.2 1.1
5 4 16 1.5 1.0
6 4 17 2.4 1.2
7 3 19 3.0 1.4
8 3 19 3.0 1.2
I need result in while loop as below : as per mysql query
$sql = "SELECT pid,owgh,nwgh from produttable
WHERE mid = 3 ";
RESULT I WANT AS BELOW :
Product Id | Old weight | New weight
---------------------------------------
12 1.5 0.6
12 1.5 0.3
Tot: 3.0 0.9
--------------------------------
14 0.6 0.4
Tot: 0.6 0.4
--------------------------------
15 1.2 1.1
Tot: 1.2 1.1
--------------------------------
19 3.0 1.4
19 3.0 1.2
Tot: 6.0 2.6
$query = mysql_query($sql);
echo"<table>
<tr>
<td> Product Id </td>
<td> Old Weight </td>
<td> New Wight </td>
</tr>
";
while($row = mysql_fetch_array($query )){
echo "<tr>";
echo "<td>".$row['pid']."</td>";
echo "<td>".$row['owgh']."</td>";
echo "<td>".$row['nwgh']."</td>";
echo "</tr>";
echo "<tr><td>-----</td>
<td>Tot : </td>
<td> </td></tr>";
}
echo "
</table>";
But result i am getting is as below
Product Id | Old weight | New weight
---------------------------------------
12 1.5 0.6
-------------- Tot
12 1.5 0.3
---------------Tot
14 0.6 0.4
---------------Tot
15 1.2 1.1
---------------Tot
19 3.0 1.4
---------------Tot
19 3.0 1.2
which i dont want , i want as below :
Product Id | Old weight | New weight
---------------------------------------
12 1.5 0.6
12 1.5 0.3
Tot: 3.0 0.9

Update : 30/3/2015
Can i get below result, with sum of each
Product Id | Old weight | New weight
---------------------------------------
12 1.5 0.6
12 1.5 0.3
Tot: 3.0 0.9
--------------------------------
14 0.6 0.4
Tot: 0.6 0.4
--------------------------------
15 1.2 1.1
Tot: 1.2 1.1
--------------------------------
19 3.0 1.4
19 3.0 1.2
Tot: 6.0 2.6
-----------------------------------
GRAND TOTAL = 6.3 5
PLEASE NOTE : OLD WEIGHT VALUE HAS REPEAT WEIGHT , HENCE WHILE GRAND TOTAL ITS SINGLE VALUE IS TAKEN
OR
Product Id | Old weight | New weight
---------------------------------------
12 1.5 0.6
1.5 0.3
Tot: 3.0 0.9
--------------------------------
14 0.6 0.4
Tot: 0.6 0.4
--------------------------------
15 1.2 1.1
Tot: 1.2 1.1
--------------------------------
19 3.0 1.4
3.0 1.2
Tot: 6.0 2.6
-----------------------------------
GRAND TOTAL = 6.3 5
PLEASE NOTE : OLD WEIGHT VALUE HAS REPEAT WEIGHT , HENCE WHILE GRAND TOTAL ITS SINGLE VALUE IS TAKEN
as product id 12, 19 are coming twice hence shown once with its resp value
Please help me, if i am wrong in HTML tr td format please correct me , it not necessary to get in same table tr,td ..i just want my result in above format
解决方案 Try this
$oldsubtotal = 0;
$newsubtotal = 0;
$olsgrandtotal = 0;
$newgrandtotal = 0;
while($row = mysql_fetch_array($query )){
if(isset($prev) && ($prev != $row['pid'])){
echo "<tr><td style='text-align: right'>Total</td><td>".$oldsubtotal."</td><td>".$newsubtotal."</td></tr>"
echo "<tr><td colspan="3">-----</td></tr>";
$oldsubtotal = 0;
$newsubtotal = 0;
}
echo "<tr>";
echo "<td>.$row['pid'].</td>";
echo "<td>.$row['owgh'].</td>";
echo "<td>.$row['nwgh'].</td>";
echo "</tr>";
$oldsubtotal += $row['owgh'];
$newsubtotal += $row['nwgh'];
$olsgrandtotal += $row['owgh'];
$newgrandtotal += $row['nwgh'];
$prev = $row['pid'];
}
echo "<tr><td style='text-align: right'>Grand Total</td><td>".$olsgrandtotal."</td><td>".$newgrandtotal."</td>"
