php form

deltaforce229

hi i have never made a php form before and i need a little help on how it works.

what i want do do is have a php file that reads lines for a txt document and displays them. at the bottom of the php file i want to make a form that allows users to submit lines to the txt document without usuing sql.
i have been told this is possible but im not sure how to do it.

if some one could show me how to do this or show me some example code it would make me very happy

<?php
$path = '/path/to/file.txt';
$contents = trim(file_get_contents($path));

if (isset($_POST['submit']) && $_POST['newline'])
{
	$contents .= "\r\n" . stripslashes(trim($_POST['newline']));
	file_put_contents($path, $contents) or exit('error writing to file');
}

$contents = explode("\n", $contents);
echo 'contents of ' . $path . ':<br><br>';
foreach ($contents as $key => $value) {echo nl2br($value);}

echo '
<form action="" method="POST">
add new line: <input type="text" name="newline"><br>
<input type="submit" name="submit" value="submit">
</form>
';
?>

i'v been away since i posted this topic and i just got back now.

Fatal error: Call to undefined function: file_put_contents() in /home/gaconlin/public_html/test/xfire.php on line 8

your script has bugs

jansky

file_put_contents() works only php version 5
alternative to this is fopen(), fwrite() and fclose() function

what php version are you using??
try

<?phpinfo();?>

i have version 4 but fwrite doesnt work either.

Warning: fwrite(): supplied argument is not a valid stream resource in /home/gaconlin/public_html/test/xfire.php on line 8
error writing to file

That error just means that the filestream you created using fopen isnt valid for some reason. It could be that you forgot to use fopen to create the stream, or that the perms for the file arent correct (although I believe thats a different error)...post up the code, and we may be able to tell you more

i didnt really want to tell anyone what this script was for but its for xfire

<?php
$path = 'xfire.txt';
$contents = trim(file_get_contents($path));

if (isset($_POST['submit']) && $_POST['newline'])
{
    $contents .= "\r\n" . stripslashes(trim($_POST['newline']));
    fwrite($path, $contents) or exit('error writing to file');
}

$contents = explode("\n", $contents);
echo ('<html>
<head>
<title>
Xfire Sig List
</title>
</head>
<body>
<center>
Xfire Signature List
<table border="1" cellspacing="0" cellpadding="0">
  <tr>
    <td>
<center>
<form action="" method="POST">
Xfire Screenname: <input type="text" name="newline"><br>
<input type="submit" name="submit" value="submit">
</form>
</center>
</td>
    <td>');

foreach ($contents as $key => $value) {echo ('<img src="http://miniprofile.xfire.com/'.$value.'.png">');}

echo ('
</td>
  </tr>
</table>
</center>
</body>
</html>');
?>

OK. to use fwrite, you need to first create a filestream.

if (isset($_POST['submit']) && $_POST['newline'])
{
    $handle=fopen($path,"a");
    $contents .= "\r\n" . stripslashes(trim($_POST['newline']));
    fwrite($handle, $contents) or exit('error writing to file');
    fclose($handle);
}

and I am assuming that you want to append the line, not overwrite....

ok i just tested that out and what i get is that yest a line is added but it also copys over all the other lines

edit: well it only happens if you add input that is the same as whats there
edit: if someone could contact me on aim my screen name is JLC329 it would make things easier

ok im scraping some of this

<?php
$path = 'xfire.txt';
$contents = trim(file_get_contents($path));

if (isset($_POST['submit']) && $_POST['newline'])
{
    $handle=fopen($path,"a");
    $contents .= "\r\n" . stripslashes(trim($_POST['newline']));
    fwrite($handle, $contents) or exit('error writing to file');
    fclose($handle);
}  

$contents = explode("\n", $contents);
echo 'contents of ' . $path . ':<br><br>';
foreach ($contents as $key => $value) {echo nl2br($value);}

echo '
<form action="" method="POST">
add new line: <input type="text" name="newline"><br>
<input type="submit" name="submit" value="submit">
</form>
';
?>

what i want is for <img src="http://miniprofile.xfire.com/ to be added before the text input and .png"><br> to be added after so that in the txt document it would look like this <img src="http://miniprofile.xfire.com/somestuff.png"><br>

i want the following 4 to be in a drop down box before the text input

<img src="http://miniprofile.xfire.com/bg/bg/type/1/
<img src="http://miniprofile.xfire.com/bg/os/type/1/
<img src="http://miniprofile.xfire.com/bg/co/type/1/
<img src="http://miniprofile.xfire.com/bg/sf/type/1/

and the end result of what is placed in the document would be
<img src="http://miniprofile.xfire.com/somestuff.png"><br>
