问题描述
我有文件保存textarea的问题。我用POST方法发送表单到另一个页面，然后在下一页我不能包含文件的textarea内容我不知道是什么问题。
这里有两页：
page1：
<！DOCTYPE HTML>
< html>
< head>
< title>储存< / title>
< / head>
< body>
< form action =page2.phpmethod =post>
< span>名称：< / span>
< input type =textname =name>< br>
< span>文件扩展名：< / span>
< select name =extid =ext>
< option value =。txt> .txt< / option>
< option value =。doc> .doc< / option>
< / select>
< textarea name =txt1id =txt1cols =15rows =10>< / textarea>
< br>
< input type =submitname =submitid =submitvalue =Save>
< / form>
< br>
< / body>
< / html>
-page2.php
$ txt1 = $ _POST ['txt1']; // textarea
$ name = $ _POST ['name'];
$ ext = $ _POST ['ext']; //从多个扩展中选择
if（$ ext =='.txt'）//如果我想添加多个扩展。
{
$ file ='。$ name $ ext。';
$ output =$ txt1;
file_put_contents（$ file，$ output）;
$ text = file_get_contents（$ file）;
header（Content-Description：File Transfer）;
header（Content-Type：application / text / plain）;
header（Content-Disposition：attachment; filename =。basename（$ file））;
ob_clean（）;
flush（）;
readfile（$ file）;
退出;
}
解决方案
尝试使用wrap元素你的textarea
< textarea name =txt1id =txt1cols =15rows =10> ;< / textarea的>
添加换行
< textarea name =txt1id =txt1cols =15rows =10wrap =virtual>< / textarea>
您也可以使用wrap：off，hard，soft和physical
在数据库中确保字段txt1被正确定义（即输入文本）。
I have issue saving textarea to file. I used POST method to send the form to the other page then, in the next page I can't include the textarea content with the file Im not sure what is the problem.
Is there any idea about what is the problem?
Here are the two pages: page1:
<!DOCTYPE HTML>
<html>
<head>
<title>Save</title>
</head>
<body>
<form action="page2.php" method="post">
<span>name:</span>
<input type="text" name="name"><br>
<span>file extension: </span>
<select name="ext" id="ext">
<option value=".txt">.txt</option>
<option value=".doc">.doc</option>
</select>
<textarea name="txt1" id="txt1" cols="15" rows="10"></textarea>
<br>
<input type="submit" name="submit" id="submit" value="Save">
</form>
<br>
</body>
</html>
-page2.php
$txt1 = $_POST['txt1']; //textarea
$name = $_POST['name'];
$ext = $_POST['ext']; //choose from multiple extensions
if ($ext == '.txt') // In case if I want to add more than extension.
{
$file = "'. $name$ext.'" ;
$output = "$txt1";
file_put_contents($file, $output);
$text = file_get_contents($file);
header("Content-Description: File Transfer");
header("Content-Type: application/text/plain");
header("Content-Disposition: attachment; filename=".basename($file));
ob_clean();
flush();
readfile($file);
exit;
}
解决方案
Try using the wrap element in your textarea
<textarea name="txt1" id="txt1" cols="15" rows="10"></textarea>
add wrap
<textarea name="txt1" id="txt1" cols="15" rows="10" wrap="virtual"></textarea>
you can also use wrap: off, hard, soft and physical
In your database make sure the field txt1 is defined properly (i.e type text).
