我想使用CodeIgniter從數據庫檢索數據。查詢工作正常,並將數據檢索到一個數組,可以用print_array()
顯示數據。使用codeigniter從數據庫中檢索數據
Array
(
[0] => Array
(
[trans_id] => 33
[CustomerAccountNumber] => BR002
[TransactionType] => Invoice
[TransactionDate] => 2012-09-06 00:00:00
[InvoiceNo] => 00001732262
[OrderNo] => 0000183946
[GoodsValueInAccountCurrency] => 1055.26
[AccountBalance] => 1104.52
[SYSTraderTranTypeID] => 4
)
[1] => Array
(
[trans_id] => 34
[CustomerAccountNumber] => BR002
[TransactionType] => Invoice
[TransactionDate] => 2012-09-19 00:00:00
[InvoiceNo] => 00001375022
[OrderNo] => 0000184907
[GoodsValueInAccountCurrency] => 49.26
[AccountBalance] => 1104.52
[SYSTraderTranTypeID] => 4
)
)
但每當我試圖在表中顯示的數據來生成PDF,它給了我一個錯誤,指出「試圖獲得非對象的屬性」。但是所有的對象都進入了一個數組來顯示。這是我的代碼:
print_array($data['data']);
{ foreach ($data['data'] as $key=>$link)
{
{
$html .= '
<tr>
<td width = "100">'.$link->InvoiceNo.'</td>
<td width = "300">'.($link->OrderNo).'</td>
<td width = "100">'.($link->TransactionDate).'</td>
<td width = "100">'.($link->TransactionType).'</td>
<td width = "100">'.($link->GoodsValueInAccountCurrency).'</td>
</tr>';
}
}}
但是這給了我錯誤「試圖獲得非對象的屬性」。我沒有得到任何線索。爲什麼?請幫忙。

嘗試使用$ link [「key」]而不是$ link-> key – deadlock 2013-03-08 11:56:13
您可能正在使用CI中的result_array()函數來獲取數組。你可以使用result()來獲取結果數組作爲對象。 – Prashank 2013-03-08 12:03:46
