如何取回<textarea> POST 值并保存到文件？

Question

On the page "index.php", I have the following html:

<form class="centerd" method="post" action="upload.php" enctype="multipart/form-data">
    <textarea id="html" type="text" name="html-text"></textarea>
    <input type="submit" value="upload"/>
</form>

On the page "upload.php", I have the following PHP code:

<?php
file_put_contents("/files/test.html", htmlspecialchars($_POST['html-text']));
?>
<h1>From the textbox:</h1>
<? echo htmlspecialchars($_POST['html-text']); ?>

I want the text from the textbox to show up after the <h1> tag, and I want /files/test.html to be created ( /files/ already exists), and the text from the textbox to be put into the test.html file.

What actually happens, is whatever is in the textbox shows up after the <h1> tag, but /files/test.html is never created.

Answer 1

It looks like "/files/test.html" is an absolute path. Have you tried "files/test.html" ?

Answer 2

I'm sorry that I cannot comment on what Brannon said, I simply don't have reputation for it yet. But to the point:

There are two possibilities:

1. As Brannon said -> your path seems to be wrong.
2. You don't have permission to write (create) files in your directory. This can, in my experience, be a common error for Mac users who haven't provided permission in their htdocs folder.

Answer 3

you forgot the php!

not: <? echo ?> <? echo ?> but: <?php echo ?>
