Question

我已经掌握了这个PHP脚本，并使用它来从上一页的表单加载信息到我当前页面上的表单：

<?php

$addy = $_POST["addy"];
$imgchan = $_POST["imgchan"];
$textcol = $_POST["textcol"];
$texfont = $_POST["texfont"];
$motifsel = $_POST["motifsel"];
$motifcol = $_POST["motifcol"];
$postad = $_POST["postad"];
$emailad= $_POST["emailad"];
$custnme1= $_POST["custnme1"];
$amnt= $_POST["amnt"];
$waxs= $_POST["waxy"];
$adhel= $_POST["adhesy"];
$mult = $_POST["mult"];
$waxmul= $waxs * 1.50;
$adhemul= $adhel * 1.20;
$finalfig= $waxmul + $adhemul + $mult;

?>

我使用＆＃34; php echo htmlspecialchars（$ finalfig）＆＃34;传递它们。作为形式中的值，可以看到它将它们放在形式上

当我单击表单上的确认时，它会显示第一个表单的未定义索引，即使我没有将该表单传递到下一页。实际上PHP脚本已经达到了它的目的，我不明白它为什么再次对它进行裁判。

帮助！

以下是指向整页所需的链接

Thank you for your submission!

Answer 1

注意错误不是致命的，也不是关键的错误，但会告诉您潜在的隐藏错误并鼓励更安全的编码（这意味着在这种情况下更多代码）。

您可以调整PHP的error_reporting级别来解除它们。

很可能问题出在最后一节。如果您正在调用htmlspecialchars（$ blank_variable）[并且您]，您肯定会收到此错误消息。

您可能希望在表单上方执行此操作：

if (isset($mult)) $mult = htmlspecialchars($mult); //do this for all variables
?>

<div style = "position: absolute; left: 180px; top: 730px;" >
<form action="testing.php" method="post">
<input type="text" name="mult" id="mult" value="<?php echo $mult; ?>" maxlength="62">

Answer 2

您的输入名称与$ _POST数组索引不匹配。例如，您使用

name=“addy”

在FinalOrder.php中，但是

$addy = $_POST[“addy1”];

在testing.php中。它们应该是“addy”或“addy1”。

Answer 3

答案绝对荒谬！这是我提交的表格上面的一个偏离，这让人感到困惑。
