class.upload.php和文件擴展名丟失

Question

我正在使用class.upload.php獲取圖像。 調整大小可以正確使用名稱和擴展名進入文件夾，但是將名稱存儲到mysql數據庫時出現問題。 沒有文件擴展名（.jpg，.gif等）...為什么？ 我該如何解決該問題？ 謝謝

            $files[$i] = array();

您已經在這里使用str_replace用空字符串替換了擴展

$result_small = str_replace("." . $extension,"",$image1);

和這里

$result_big = str_replace("." . $extension,"",$image1);

更新以下幾行只需在末尾添加.$extension

$handle->file_new_name_body   =  $result_big.$extension;

和

 $handle->file_new_name_body   =    $result_small.$extension;

只是像這樣更改查詢

$query_img="INSERT into tbl_images ( 
                file_name, 
                pd_image, 
                pd_thumbnail
             ) VALUES (
               '$nome',
               '{$result_big}.{$extension}', 
               '{$result_small}.{$extension}')";   

我建議您為pd_image和pd_thumbnail使用相同的文件名，只是在thumb之前加上thumb_ ，這樣可以使您的生活更加輕松。

這樣你可以用前綴它訪問任何圖像縮略圖thumb_與pd_image ，你不必存儲pd_thumbnail數據庫。

您正在使用以下代碼刪除擴展名：$ result_big = str_replace（“。”。$ extension，“”，$ image1）;

我不知道你為什么這樣做。 無論如何，您可以通過在$ handle-> file_new_name_body = $ result_big之后添加以下行來將其重新添加回去。

$ handle-> file_new_name_ext = $ extension;
