问题描述

 $ query =   SELECT Distinct company，car_moto，packet FROM user where user ='$ userid'ORDER BY company，car_moto，packet; 
 $ result = mysql_query（$ query）; 
 $ num = mysql_numrows（$ result）; 
 
 $ i = 0; 
  while （$ i< $ num）{
 $ f0 = mysql_result（$ result，$ i，  company）; 
 $ f1 = mysql_result（$ result，$ i，  car_moto）; 
 $ f2 = mysql_result（$ result，$ i，  packet）; 
 
  $ sql_1  =   SELECT SUM（price_protect）作为partpaid1 FROM公司，其中company ='$ f0'和car_moto ='$ f1'且packet ='$ f2'和userid ='$ userid'; 
  $ sql_2  =   SELECT SUM（clear_protect） ）作为partpaid2 FROM公司='$ f0'和car_moto ='$ f1'和packet ='$ f2'和userid ='$ userid'; 
 $ result_1 = mysql_query（$ sql_1）或 die（' 错误查询失败'）; 
 $ result_2 = mysql_query（$ sql_2）或 die（' 错误查询失败'）; 
 
  while （$ row_1 = mysql_fetch_array（$ result_1））{
  $ invoicepartpaid1  = $ row_1 ['  partpaid1']; 
} 
  while （$ row_2 = mysql_fetch_array（$ result_2））{
  $ invoicepartpaid2  = $ row_2 ['  partpaid2']; 
} 
  echo   < ; tr>< td align ='center'><< span> $ f0< / span>< / td>< td align ='center'>< span> $ f1< / span>< / td>< td align ='center'>< span> $ f2< / span>< / td>< td align ='center'>< span> $ invoicepartpaid1& lt; / span> < / td>< td align ='center'>< span> $ invoicepartpaid2< / span>< / td>< / tr>; 
 
 $ i ++; 
 
}

结果

< span> $ invoicepartpaid1< / span> ;

和

< span> $ invoicepartpaid2< / span>

为空。应该有钱。有什么建议吗？

解决方案

$query="SELECT Distinct company, car_moto, packet FROM companies where userid='$userid' ORDER BY company, car_moto, packet";
$result=mysql_query($query);
$num=mysql_numrows($result);

$i=0;
while ($i < $num) {
  $f0=mysql_result($result,$i,"company");
  $f1=mysql_result($result,$i,"car_moto");
  $f2=mysql_result($result,$i,"packet");

  $sql_1 = "SELECT SUM(price_protect) as partpaid1 FROM companies where company='$f0' and car_moto='$f1' and packet='$f2' and userid='$userid'";
  $sql_2 = "SELECT SUM(clear_protect) as partpaid2 FROM companies where company='$f0' and car_moto='$f1' and packet='$f2' and userid='$userid'";
  $result_1=mysql_query($sql_1) or die('Error query failed');
  $result_2=mysql_query($sql_2) or die('Error query failed');

  while ($row_1 = mysql_fetch_array($result_1)) {
    $invoicepartpaid1 = $row_1['partpaid1'];
  }
  while ($row_2 = mysql_fetch_array($result_2)) {
    $invoicepartpaid2 = $row_2['partpaid2'];
  }
  echo "<tr><td align='center'><span>$f0</span></td><td align='center'><span>$f1</span></td><td align='center'>< span>$f2</span></td><td align='center'><span>$invoicepartpaid1& lt;/span></td><td align='center'><span>$invoicepartpaid2</span>< /td></tr>";

  $i++;

}

The Results of

<span>$invoicepartpaid1</span>

and

<span>$invoicepartpaid2</span>

are blank. There should be sums. Any suggestion?
