使用php表单创建一个名为的文件 - create a file with name using php form

create a file with name using php form

填写一个表单，其中包含两部分，文件名和文本。我需要在html目录中创建一个名为$filename的文件，并获取我放入$text中的文本。不幸的是，我无法使它工作有什么帮助吗：

表单代码：

<form method="post" action="createfile.php">
<font size"3"><b>File name:</b> </font>
<br /><input type="text" size="15" name="filename" id="filename"><br />
<font size"3"><b>File data:</b> </font>
<div id="dat"><textarea name="thedata" id="thedata" cols="30" rows="15"></textarea></div>
<div id="sub" style="position:absolute; left: 25">
<input type="submit" value=" Create ">
</div>
</form>

createfile.php代码：

<?php 
$name= $filename; 
$data= $thedata; 
if ( $file && $data ) { 
$fp = fopen($file, "w");  
fwrite($fp, "<br>"); 
fwrite($fp, $data); 
fclose($fp); 
} 
else 
{ echo 'no text entered'; 
} 
?>

感谢的帮助

HTML将相同：

<form method="post" action="createfile.php">
<font size"3"><b>File name:</b> </font>
<br /><input type="text" size="15" name="filename" id="filename"><br />
<font size"3"><b>File data:</b> </font>
<div id="dat"><textarea name="thedata" id="thedata" cols="30" rows="15"></textarea></div>
<div id="sub" style="position:absolute; left: 25">
<input type="submit" value=" Create ">
</div>
</form>

PHP:

<?php
$filename = $_POST['filename'];
$content  = $_POST['thedata'] ;
$if(!isset($_POST['filename'])){
    //i leave the filename && content validation to the client side
    $handle = fopen("/files/$filename.txt", "w");
    fwrite($handle, $content);
    fclose($handle);
}else{
    //your `else` code here.
}
?>

使用以下代码：

<?php
$name= isset($_POST['filename'])?$_POST['filename']:0; 
$data= isset($_POST['thedata'])?$_POST['thedata']:0;  
if ($name && $data ) { 
$fp = fopen($name, "w");  
fwrite($fp, "<br>"); 
fwrite($fp, $data); 
fclose($fp); 
} 
else { 
echo 'no text entered'; 
} 
?>
