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);
