报纸
要多少钱
嗨,这里有一个关于php的noob。有一个问题,由于某种原因,我无法让所选的阵列继续到响应页面,其中将显示从上一个阵列中选择的内容,如果选择了该报纸,将显示第二个阵列中的正确价格 您使用报纸的位置作为选项值中的键。这意味着您可以这样使用它:
<?php
$newspaper=$_POST['newspaper'];
$newspaperNames= array ("The Guardian", "The Times", "The Sun", "The Mirror");
$newspaperPrice= array('0.9','1','0.5','0.5');
?>
<html>
<head>
<title>Newspaper</title>
</head>
<body>
<h1>How much does it cost</h1>
<?php
print "<p> Your Newspaper is " .$newspaper. "</p>";
print "<p>Your Newspaper is " .$newspaper. "</p>";
if ($newspaper== "The Guardian") {
print "<p>Your newspaper cost " .$newspaperPrice[0]."</p>";
} else
?>
</body>
</html>
报纸
要多少钱
- 注意:请检查输入是否已发布(
)isset()
- 用
echo
替换print
s,就像yarwest说的那样
要在PHP中打印某些内容,您必须使用
echo
(就像您在表单中所做的那样)。您还可以在带有双引号的字符串中使用变量。例如:
echo“您的报纸是$paper”
除此之外,还有一个没有条件或主体的else语句
修复此问题,我相信您将更接近工作状态。将您的数组放入另一个文件中,并从以下两个文件中包括它:
<?php
$newspaper = $_POST['newspaper'];
$newspaperNames= array ("The Guardian", "The Times", "The Sun", "The Mirror");
$newspaperPrice= array('0.9','1','0.5','0.5');
?>
<html>
<head>
<title>Newspaper</title>
</head>
<body>
<h1>How much does it cost</h1>
<?php
echo "<p>Your Newspaper is " .$newspaperNames[$newspaper]. "</p>";
echo "<p>Your newspaper cost " .$newspaperPrice[$newspaper]."</p>";
?>
</body>
</html>
...
在您的回复页面中
<p>Which newspaper are you interested in?
<select name="newspaper">
<?php
include 'papers.inc';# or whatever
foreach ($newspapers as $index => $newspaper) {
echo '<option value="', $index, '">', $newspaper['name'], '</option>';
}
?>
...
...
你的报纸很贵,要多少钱
对于调试,您可以使用print\r($\u POST)True。我认为最好使用多维数组而不是两个数组。但这更多地取决于脚本的使用方式和代码创建者的“风格”。
<p>Which newspaper are you interested in?
<select name="newspaper">
<?php
include 'papers.inc';# or whatever
foreach ($newspapers as $index => $newspaper) {
echo '<option value="', $index, '">', $newspaper['name'], '</option>';
}
?>
...
<?php
include 'papers.inc';
$index = $_POST['newspaper'];
?>
...
<p>Your newspaper is <?php echo $newspapers[$index]['name'];?>, which costs <?php echo $newspapers[$index]['price'];?>
