我寫了一個有關購物車的程式碼... 不過在本機執行的時候... 由shop1.php執行把物品放入購物車時... <a href="sebuy.php?F_No=<? echo $row_rsTb1['F_No'];?>&F_Name=<? echo $row_rsTb1['F_Name'];?>">放入購物車</a></td> 可是到了該頁面的時候... 如果我在sebuy.php打上"<?php ehco F_No; ?> 卻顯示不出來.... 但網址列那邊有正確的顯示出來... 下面是我的程式碼.... <shop1.php> <? $link_ID=mysql_connect(""," "," "); mysql_query("set names big5;"); ?> <?php $currentPage = $HTTP_SERVER_VARS["PHP_SELF"]; $maxRows_rsTb1 = 10; $pageNum_rsTb1 = 0; if (isset($HTTP_GET_VARS['pageNum_rsTb1'])) { $pageNum_rsTb1 = $HTTP_GET_VARS['pageNum_rsTb1']; } $startRow_rsTb1 = $pageNum_rsTb1 * $maxRows_rsTb1; $link_ID=mysql_connect(" "," "," "); mysql_query("set names big5;"); mysql_select_db(" "); $query_rsTb1 = "SELECT * FROM MENU"; $query_limit_rsTb1 = sprintf("%s LIMIT %d, %d", $query_rsTb1, $startRow_rsTb1, $maxRows_rsTb1); $rsTb1 = mysql_query($query_limit_rsTb1, $link_ID) or die(mysql_error()); $row_rsTb1 = mysql_fetch_assoc($rsTb1); if (isset($HTTP_GET_VARS['totalRows_rsTb1'])) { $totalRows_rsTb1 = $HTTP_GET_VARS['totalRows_rsTb1']; } else { $all_rsTb1 = mysql_query($query_rsTb1); $totalRows_rsTb1 = mysql_num_rows($all_rsTb1); } $totalPages_rsTb1 = ceil($totalRows_rsTb1/$maxRows_rsTb1)-1; $queryString_rsTb1 = ""; if (!empty($HTTP_SERVER_VARS['QUERY_STRING'])) { $params = explode("&", $HTTP_SERVER_VARS['QUERY_STRING']); $newParams = array(); foreach ($params as $param) { if (stristr($param, "pageNum_rsTb1") == false && stristr($param, "totalRows_rsTb1") == false) { array_push($newParams, $param); } } if (count($newParams) != 0) { $queryString_rsTb1 = "&" . implode("&", $newParams); } } $queryString_rsTb1 = sprintf("&totalRows_rsTb1=%d%s", $totalRows_rsTb1, $queryString_rsTb1); ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=big5"> <title>選擇商品</title> </head> <body> <table border="0" cellpadding="1" cellspacing="1"> <tr bgcolor="#CCCCFF"> <td height="19">NO.</td> <td>名稱</td> <td>價格</td> <td>商店</td> <td>類別</td> <td>其他</td> <td> </td> </tr> <? $i = 0 ?> <?php do { $i+=1; if ($i % 2 == 0){ $P="CCFFCC"; }else{ $P="CCFFFF"; } ?> <tr bgcolor="#<?php echo $P; ?>"> <td><?php echo $row_rsTb1['F_No']; ?></td> <td><?php echo $row_rsTb1['F_Name']; ?></td> <td><?php echo $row_rsTb1['F_Price']; ?></td> <td><?php echo $row_rsTb1['S_No']; ?></td> <td><?php echo $row_rsTb1['Type_No']; ?></td> <td><?php echo $row_rsTb1['F_Name']; ?></td> <td width="90"><a href="sebuy.php?F_No=<? echo $row_rsTb1['F_No'];?>&F_Name=<? echo $row_rsTb1['F_Name'];?>">放入購物車</a></td> </tr> <?php } while ($row_rsTb1 = mysql_fetch_assoc($rsTb1)); ?> </table> <p>  商品<?php echo ($startRow_rsTb1 + 1) ?> 到 <?php echo min($startRow_rsTb1 + $maxRows_rsTb1, $totalRows_rsTb1) ?> 共 <?php echo $totalRows_rsTb1 ?> 種產品 <form name="form2" method="post" action="shopcar.php"> <input type="submit" name="Submit" value="結帳"> </form> <table border="0" width="50%" align="center"> <tr> <td width="23%" align="center"> <?php if ($pageNum_rsTb1 > 0) { // Show if not first page ?> <a href="<?php printf("%s?pageNum_rsTb1=%d%s", $currentPage, 0, $queryString_rsTb1); ?>">第一頁</a> <?php } // Show if not first page ?> </td> <td width="31%" align="center"> <?php if ($pageNum_rsTb1 > 0) { // Show if not first page ?> <a href="<?php printf("%s?pageNum_rsTb1=%d%s", $currentPage, max(0, $pageNum_rsTb1 - 1), $queryString_rsTb1); ?>">上一頁</a> <?php } // Show if not first page ?> </td> <td width="23%" align="center"> <?php if ($pageNum_rsTb1 < $totalPages_rsTb1) { // Show if not last page ?> <a href="<?php printf("%s?pageNum_rsTb1=%d%s", $currentPage, min($totalPages_rsTb1, $pageNum_rsTb1 + 1), $queryString_rsTb1); ?>">下一頁</a> <?php } // Show if not last page ?> </td> <td width="23%" align="center"> <?php if ($pageNum_rsTb1 < $totalPages_rsTb1) { // Show if not last page ?> <a href="<?php printf("%s?pageNum_rsTb1=%d%s", $currentPage, $totalPages_rsTb1, $queryString_rsTb1); ?>">最後一頁</a> <?php } // Show if not last page ?> </td> </tr> </table></p> </body> </html> <?php mysql_free_result($rsTb1); ?> 下面是sebuy.php的程式碼... <HTML><HEAD> <meta http-equiv="Content-Type" content="text/html; charset=big5"> </HEAD><BODY> <? echo $F_Name;//就是這邊顯示不出來,所以下面也沒辦法確認是那一件物品 ?> <P>請輸入您購買的數量</P> <P><font color="#800000">如果只購買一件產品請直接按確定</font></P> <P><font color="#FF0000">如果不小心將沒有要購買的產品放入購物車</font></P> <form name="form2" method="post" action="shop1.php">→→→→請按這裡消除記錄→→→→ <input type="submit" name="Submit2" value="我放錯產品到購物車了，我要把產品放回架上去"> </form> <HR> <form method="post" name="form1" action="sebuy2.php?F_No=$F_No&F_Name=$F_Name">您想要丟幾件產品進購物車？ <input name="mabq" type="text" id="mabq" maxlength="4" size="4" value="1"> <input name="F_No" type="hidden" id="F_No" value="<?php echo $F_No; ?>"> <input name="F_Name" type="hidden" id="F_Name" value="<?php echo $F_Name; ?>"> <input type="submit" name="Submit" value="數量確定了，我要把購物車推回去繼續購買產品"> </form> </BODY> </HTML> -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 218.168.82.126
