I'm using file_put_contents() to post text from a text field. I want to post the data to a specific part of the page.
file_put_contents('filename.php /* #fooid */', $formData, FILE_APPEND);
Is there a way to add an id to post to?
Thanks in advance.
Until I get clarification, here's what I think you might be needing:
<div>
<div id="something">
Something else here
</div>
<div id="fooid">
<?php echo file_get_contents('filename.txt'); ?>
</div>
...
etc. I just don't understand what you're trying to do.
OK, I'll bite.
What you are trying to do here is to have POST from one PHP page actually modify the code on another PHP page. Not trying to be condecending here, since I know you're new at this, but that is a VERY BAD IDEA in bold and all caps for so many reasons I can't even begin to explain it. I suspect the reason that others have had such a hard time understanding your question is that it would never have even occurred to them to try doing something like that. That's how bad it is :)
That said, what you really want to do is take some data that you are posting from one page and display it in another. Normally you would accomplish this by storing the posted data in a database, then retrieving that data from the database on the other page and displaying it.
Rather than get into how to work with databases in PHP, I'll give you a simpler way to do it. What you want to do is have the form doing the POST write the posted data to a text file and then read that text file and display its contents on the other page. You could do that fairly simply like this, where Admin Page is the page you are posting from and View Page is the page you want to view the data on:
Admin Page
<?php
$data = $_POST["mydata"];
file_put_contents("data.txt", $data, FILE_APPEND);
?>
<form method="POST">
<textarea name="mydata"></textarea>
<input type="submit" name="submit" value="Submit"/>
</form>
So, the admin page takes the post data and writes it into a file called "data.txt"
View Page
<html>
<body>
<!-- more html... -->
<div id="fooid">
<?php echo file_get_contents("data.txt") ?>
</div>
And the view page reads the data.txt file and displays the contents at the correct place.
Note that this is all sans error handling & input validation which are of course important things, but it gives you the general idea.
