Text editor save to file

[chloebyte]

For some reason its not saving input to the text file.

 

 

 

<form action="edit.php" method="post">

<textarea Name="update" cols="50" rows="10">
</textarea>Enter text here<br/>

<input type="submit" value="update"/>

</form>

<?php
$_POST['update'];
$file1 = "file.txt";
$file = fopen($file1, "w+");
 
$contents = file_get_contents($file1);
file_put_contents($file1, $contents);
if($_POST['update'])
fwrite($file, $file1);
 
 
fclose($file);
?>

anyone know why?;/

1) You have not assigned this

$_POST['update'];

to a variable. I presume that line is meant to read as

$update = $_POST['update'];

2) Open the file use append mode

$file = fopen($file1, "a");

Then there is no need for this

$contents = file_get_contents($file1);
file_put_contents($file1, $contents);

3) fwrite takes the file handler as the first argument and the value to be written as the second argument (needs to be $update not $file1)

fwrite($file, $update);

The alternative is not use fopen/fwrite/fclose  but to use only file_put_content using the FILE_APPEND flag

if(isset($_POST['update']))
{
  $file = "file.txt";
  $update = $_POST['update'];
  file_put_contents($file, $update, FILE_APPEND); // append $update the file.txt
}

Thank you very much!
