我有一個將項目導出到csv文件的導出腳本。我想爲csv文件中每個產品行上的每個項目導出額外的圖像。 這一部分看起來是這樣的：導出文件中的foreach循環前綴數據
$img_query=tep_db_query("SELECT additional_images_id, products_id, popup_images
FROM " . TABLE_ADDITIONAL_IMAGES . "
WHERE products_id=" . $products['products_id'] ."");
if (!tep_db_num_rows($img_query)) {
$imageextra2 = " ";
} else {
$img_rows=tep_db_num_rows($img_query);
while ($img = tep_db_fetch_array($img_query)) {
$img2 = $img['popup_images'];
$pid = $img['products_id'];
$a = array($img2);
foreach($a as &$img){
}
foreach($a as $imageextra) {
$imageextra = "http://www.URL.com/images/". $img2.";";
$imageextra2 .= $imageextra;
}
} }
但是，當我出口超過一個產品，它具有更多的圖片來自行abowe圖像遵循以CSV文件的下一行。這是一個結果的實例。每個項目有一個額外的圖像：
Item-A;AdditionalImage-A.jpg;AdditionalImage-A2.jpg
Item-B;AdditionalImage-A.jpg;AdditionalImage-A2.jpg;AdditionalImage-B.jpg;AdditionalImage-B2.jpg
Item-C;AdditionalImage-A.jpg;AdditionalImage-A2.jpg;AdditionalImage-B.jpg;AdditionalImage-B2.jpg;AdditionalImage-C.jpg;AdditionalImage-C2.jpg
我能做些什麼來得到這個工作？
乾杯， 弗雷德裏克

如果將其刪除，那麼即使該項目有多個附加圖像，導出文件中也只會顯示其中一幅附加圖像。 但這可能是錯誤的做法。 – 2012-02-01 20:35:17
是的，錯誤的方式。你正在做的就是循環訪問一個數組，並且完全不做任何事情。在那個循環之後，一切仍然是進入循環之前的方式。 – 2012-02-01 20:59:19
第一次取消註釋時，我一定犯了些錯誤。我再次刪除它，你完全正確。它沒有必要在那裏。 – 2012-02-02 14:35:16
