我的任务是将表单数据保存到文本文件。但是,php没有被执行.. 即使在点击提交按钮后,文本文件也是空的.. 请让我知道这些缺陷 MYHTML
<form id="form" name="form" method="post" action="Input2.php">
<label>Choose my Map set :
</label>
<select name="Mapset">
<option value="Global network">Global Network</option>
</select> <br>
<br>
<label>Tiff code:
</label>
<select name="Tiff">
<option value="MX">MX</option>
</select> <br> <br>
<label>Physical size :
</label>
<input type="text" name="size" size="10"><br>
<label>time:
</label>
<input type="text" name="time" size="10"><br>
<div style="text-align: center"><br>
<input type="submit" name="submit" id="submit" value="Next" class="submit">
<div class="spacer"></div>
</form>
我的PHP:
if (isset($_POST['submit'])) {
$data = $_POST['size'];
$data = $_POST['time'];
$file = "input.txt";
$fp = fopen($file, "a") or die("Couldn't open $file for writing!");
fwrite($fp, $data) or die("Couldn't write values to file!");
fclose($fp);
echo "Saved to $file successfully!";
}
header("location:NetOptInput3.html");
答案 0 :(得分:1)
这里尝试(测试)
您需要指定$_POST
值才能告诉它“保存在文件中”。
这样做的方法是它将占用所有POST值。
您还可以像这样分配单个变量:
$size=$_POST['size'];
添加了备注:
你有header("location:NetOptInput3.html");
并且由于缺少空间而会失败。
这是正确的header("Location: NetOptInput3.html");
HTML表单(我删除了name="submit"
,因为它也会显示在文件中)
<form id="form" name="form" method="post" action="Input2.php">
<label>Choose my Map set :
</label>
<select name="Mapset">
<option value="Global network">Global Network</option>
</select> <br>
<br>
<label>Tiff code:
</label>
<select name="Tiff">
<option value="MX">MX</option>
</select> <br> <br>
<label>Physical size :
</label>
<input type="text" name="size" size="10"><br>
<label>time:
</label>
<input type="text" name="time" size="10"><br>
<div style="text-align: center"><br>
<input type="submit" id="submit" value="Next" class="submit">
<div class="spacer"></div>
</form>
PHP处理程序(Input2.php
)
注意:使用a
开关会附加/添加到文件中,而w
将覆盖之前保存的所有内容。
<?php
foreach($_POST as $data) {
$info = '';
$info .= $data . "\n";
$file = "data.txt";
$fp = fopen($file, "a") or die("Couldn't open $file for writing!");
fwrite($fp, $data . "\n") or die("Couldn't write values to file!");
}
fclose($fp);
// You cannot use both header and echo. Choose one.
// header("Location: NetOptInput3.html");
echo "Success";
?>
