PHP无法发布运行XAMPP的错误 [英] PHP Cannot POST error running XAMPP
问题描述
在同一目录中使用以下文件时，我在运行 XAMPP 1.8.3 和 [PHP: 5.5.15.
Using the following files in the same directory I have been getting a cannot POST error while running XAMPP 1.8.3 and [PHP: 5.5.15.
<html>
<head>
<title> IsEven </title>
</head>
<body>
<form action= "IsEven.php" method="post">
Enter a number: <input type="text" name="number" />
<input type="submit" value="submit" />
</form>
</body>
</html>
这是我的 PHP 文件
Here is my PHP file
<?php
//Assign Values to the variable.
$number = $_POST['number'];
//If statements to check Even number or not.
//Is_numeric, Isset() and round() functions.
if (is_numeric($number) && isset($number)){
if (round($number, 0) % 2 == 0){
echo "The number " .$number. " entered is a even number<br>";
}
else
{
echo "The number " . $number. " is a non-even number";
} //End round if statement.
} //End is numeric if statement
else
{
echo "Please enter a numeric value.";
}
?>
推荐答案
这是我今天在一些代码中使用的一种技术，它回答了我的问题.
Here is a technique that I used in some code today that answered my question.
<!DOCTYPE HTML>
<html>
<head>
<title> Temperature Conversion </title>
</head>
<body>
<form method="post" action= "<?php echo $_SERVER["PHP_SELF"]; ?>">
Fahrenheit: <input type="radio" name="temp_metric" value="Fahrenheit" />
Celcius: <input type="radio" name="temp_metric" value="Celcius" />
<input type="submit" name="submit" value="submit" />
</form>
</body>
</html>
<?php
//VARIABLE DECLARATIONS
$degrees = NULL;
$temp_degrees = NULL;
$curr_metric = NULL;
$converted_metric = NULL;
$converted_temp = NULL;
//LOGIC
if ('POST' === $_SERVER['REQUEST_METHOD'] and isset($_POST['temp_metric'])) {
$curr_metric = $_POST['temp_metric'];
for ($degrees = 0; $degrees <= 100; $degrees++) {
if($curr_metric == "Fahrenheit") {
$converted_metric = "Celcius";
$temp_degrees = ($degrees - 32) * (5/9);
$converted_temp = round( $temp_degrees, 1);
}
else {
$curr_metric = "Celcius";
$converted_metric = "Fahrenheit";
$temp_degrees = $degrees * 9/5 + 32;
$converted_temp = round($temp_degrees , 1);
}
//output the result of the users selection
echo "<div> $degrees $curr_metric is $converted_temp $converted_metric. </div>";
}//end of for loop
}//end of if current metric is not null
?>
我丢失的部分位于我的初始 HTML 中，以便>"使我能够将表单数据与 IF ('POST' === $_SERVER['REQUEST_METHOD']) 允许我排除 PHP，直到我点击提交按钮.
The pieces that I was missing were located in my initial HTML for action to ""> enabled me to post the form data back to the PHP file combined with the IF ('POST' === $_SERVER['REQUEST_METHOD']) allowed me to exclude the PHP until I clicked on the submit button.
这可能不是执行此操作的正确方法，但由于我使用的是 XAMPP，因此它可以工作.但是我确实知道，如果使用单独的 PHP 和 HTML 文件使用传统的 Web 服务器效果很好.到目前为止，我还没有在我的托管公司完全设置开发环境.暂时必须这样做.
This may not be the proper way to do this but since I am using XAMPP it works. However I do know that if one is using the traditional web server using seperate PHP and HTML files works well. As of yet I have not completely set up the development environment at my hosting company. For the time being this will have to do.
