问题描述
我的php表单提交页面一直失败。它在每个$ _POST ['']变量中给出一个未定义的索引错误。我把它们放在我应该的括号中。有什么问题？
代码：
My php form submit page keeps failing. it gives a undefined index error at every $_POST[''] variable. I put them in brackets where I should. What is wrong?
Code:
<?php
$ourFileName = $_POST['title'] .".html";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
$myFile = "servers.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = <<<EOD
<a href="{$_POST['title']}.html">{$_POST['title']}</a><br>
EOD;
fwrite($fh, $stringData);
fclose($fh);
$myFile = $_POST['title'] .".html";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = <<<EOF
<!DOCTYPE html>

</p>
</div>
</body>
</html>
EOF;
fwrite($fh, $stringData);
fclose($fh);
?>
第一个未定义的索引错误在第2行
这是html表格：
The first undefined index error is at line2
Here is the html form:
<form action="spost.php">
Title: <input name="title" type="text"><br>
Username (ANY): <input type="text" name="uname"><br>
<br>
Posts support html. Please put <br> at the end of each line.<br>
<br>
<textarea rows="10" cols="50" name="post"></textarea><br>
<br>
<input type="submit" value="Post">
</form>
