缺少我的第一行檢索數據庫

我想檢索數據，只是把它放到我的數據庫中。 $ bid，$ bid1，$ bid2，bidpricepl，offerpricepl已被定義。除此之外，所有的行數據都是從db中撤銷的，有一行，盈虧是一個變量。 Foreach行，這個變量的值被壓下一個檔位，意味着放置2，該值是放置位置1.我附上了一張圖片，以便大家理解。我的查詢有什麼問題？ EG表缺少我的第一行檢索數據庫

ORDERNUMBER：損益表：
sadasdasd BLANK
sadasdasd 1
sadasdasd 2
sadasdasd 3

查詢調用和顯示

嘗試if代碼移動到在echo聲明之前。

此時您正在計算出在表格中輸出該行之後的值。

E.g.

if ($row['selection']=='eur/usd') 
.. 
elseif ($row['selection']=='usd/jpy') 
elseif ($row['selection']=='usd/cad') 
elseif ($row['selection']=='eur/jpy') 
elseif ($row['selection']=='eur/chf') 
elseif ($row['selection']=='gbp/usd') 
elseif ($row['selection']=='aud/usd') 
elseif ($row['selection']=='usd/chf') 

echo "<tr><td>" . $row['trade_id'] . "</td><td>" . $row['selection'] . "</td><td>" . $row['date'] ."</td><td>" . $row['type'] ."</td><td>" . $row['size'] ."</td><td>" . $row['bidprice'] ."</td><td>" . $row['offerprice'] ."</td><td>" . $row['stoploss'] ."</td><td>" . $row['takeprofit'] ."</td><td>" . $bidpricepl . "</td><td><a href ='delete.php?id=".$row['trade_id']."'>X</a></td></tr>";
