設置會話變量和從其他.php文件計算

2017-04-04 90 views

我想使用php來設置初始loginPage.php會話變量，並顯示在paymentPage.php，但我有麻煩設置$ _SESSION變量，以便它出現。在loginPage和付款頁面之間有一個網頁，這似乎讓我失望了。設置會話變量和從其他.php文件計算

此外，我需要計算上一頁中所選項目的總數，但我不確定如何將一個美元金額與不顯示但是計算paymentPage上的總數的複選框相加。

看我真的通過您的代碼看，我不知道是否有什麼東西失蹤，但我並沒有什麼太大的意義對我來說。無論如何，如果它適合你，這很好。

這裏有一個錯字，我發現：

paymentPage.php

echo "<tr> 
     <td>" . $_SESSION['username'] . "</td> 
     <td>" . $_SESSION['emailadd'] . "</td> 
    </tr>";

而且爲你計算..我不知道的人。你讓dom有點靜態以獲得這些價值的foreach產品或任何東西。你可以做的最好的事情是給每個元素一個獨特的Id oder類，並通過JS驗證它是否得到檢查。對你來說還有很長的路要走。但是請記住，我們不寫你的代碼。

我很欣賞你的誠實，我很新，這是我從來沒有與HTML或PHP工作過。我會採納你的建議，看看我能想出什麼！我並不希望你給我代碼，只是指出我需要改進的地方以及你對我的問題的看法。謝謝！ – pCaMp

你忘了問一個問題並解釋你的問題。

訪問會話的任何頁面必須（1）以包含session_start()的PHP塊開始。您向我們展示的4個腳本中只有一個會執行此操作。

1）並不完全正確 - 但例外的討論太複雜，進入這裏

好的，每個頁面都需要包含session_start（）以便將變量傳遞給其他頁面？我會努力解決我的問題。我想我的問題是1）爲什麼我的變量沒有被傳遞給其他頁面，2）以word的形式，我應該如何去從EquineShop.php頁面獲取paymentPage.php的總金額。不尋找代碼，但我似乎無法繞過它。感謝您的幫助！ – pCaMp

我發現的另一個問題是你的三江源頁：

<form name="main" method="post" action="loginPage.php"> 
    <input type="submit" value="Log Out" /> 
    <?php 
    session_unset(); 
    session_destroy(); 
?> 
</form>

我知道你在想要做的事：當您單擊提交按鈕時，您正試圖製作一個可以刪除所有會話變量的表單。

你實際上是在做什麼：

您正在呈現一種形式，它在西港島線提交一個POST發送到loginPage.php。當你在服務器上構建這個表單時，你也已經取消了Session變量的設置。正如上面的代碼等同於代碼我在這裏下面告訴你：

<?php //deleting session state 
    session_unset(); 
    session_destroy(); 
//now lets output some html, being a form: 
?>  
<form name="main" method="post" action="loginPage.php"> 
    <input type="submit" value="Log Out" /> 
</form>
