按「提交」後用戶的PHP代碼？

我開始之前，我想感謝這個網站讓PHP更容易理解。所以我是PHP新手，這是我第一次處理表單。在下面的代碼中，我的目標是讓用戶選擇一個數量，然後點擊提交，它將打開一張發票表，說明他們在多少和總額中選擇了多少。我一直在做很多YouTube和閱讀，但仍然無法掌握如何使我的頁面做得令人興奮。請記住，我並不是想讓它看起來，只是很容易理解。這裏是我的代碼:)按「提交」後用戶的PHP代碼？

     $productImage = array('spiderman1.jpg', 'spiderman2.jpg', 'spiderman3.jpg', 'spiderman4.jpg', 'hulk1.jpg'); // I'm stil lhaving a hard time with multidimensional arrays. 
     $description = array('Amazing Spiderman #1', 'Amazing Spiderman #15', 'Amazing Spiderman #52', 'Amazing Spiderman #107', 'Hulk #181');

     //the product image array gave me a hard time, in the sense that I'm still having a hard time trying to output an image that saves onto my desktop locally. So I chose the option of grabbing the links fromt the web. Don't worry though, I won't do this for my Assignment #1. UPDATE: Problem has been fixed!  

    echo '<table border="1" align="center" cellpadding="10">'; // I'm very horrible with tables, I finally figured out how to center the text within the table.

首先，您需要更改這個'<形式行動=「<= $ _server ['PHP_SELF']？>「method =」$ _ POST「>」this'

它工作正常！不知道它是那麼簡單。謝謝 – Romel

不客氣。很高興爲你工作。 –

我不知道是否能解決你的問題，但我不相信，方法=「$ _職位」是正確的。它應該是

method="post"

然後，當您需要從表單中獲取數據時，請引用$ _POST數組。希望有所幫助。

這樣做很有道理，謝謝！ – Romel

您需要更改這個

<form action= "<= $_server['PHP_SELF'] ?>" method="$_POST">

這個

<form action= "" method="post">

或

<form action= "<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
