Hi,

 

I am writing several scripts and some are used to amend extra information to a text file. However, I added a hyperlink to the text file so that the user can go back to a page where they can add extra information. However, since I have done this every time I amend more text to the text file, the extra text appears below the hyperlink rather than above it, and I was wondering if there was a way around this.

 

My amend code is as follows:

 

<html>
<head>
<title>Amend File</title>
<link rel="stylesheet" type="text/css" a href="rcm/stylesheet.css">
</head>
<?php

if($_POST['append'] !=null)
{
$filename="C:/xampp/htdocs/rcm/denman2.txt";
$file=fopen($filename, "a");
$msg="<p>Updated Information: " .$_POST['append']. "</p><br>";
fputs ($file, $msg);
fclose($file);
}
?>
<body>
<h1>Do you want to append to a document?</h1>
Enter Updated Information:
<form action="amendfile2.php" method="post">
<input type="text" size="40" name="append"><br><br>
<input type="submit" value="Add updated information to report">
</form>
<form action="viewfile3.php" method="post">
<input type="submit" size="40" value="View Web Blog">
</form>
<form action="loginform.php" method="post">
<input type="submit" value="Click here to go to the Log In Screen">
</form>
</body></html>

 

And my text file is as follows:

<h1>Accident Report</h1>

<p>First Name: Andrew
Last Name: Denman
Age: 18
Complete Weeks Since Accident: 2<br>

<a href="amendfile2.php">Amend to this file</a>

 

Any help would be appreciated :D

You can't write to the middle of a file without overwriting whatever came after. You'd "have" to read in the whole file, make your change to the string in memory, then write it out.
