edit config.php

Ben Phelps · September 16, 2006

I am wondering how i can open a files (config.php) and change some values via a text box then save.

Example

config.php
[code]
<?php

$site_url= "http://127.0.0.1/";

?>
[/code]

I want to open config.php and change http://127.0.0.1/ to what ever is imputed in the text box.

It will be an install script when its finished

using fopen()
fwrite()
fclose()
functions

i don't have any idea how i could do that

makeshift_theory · September 16, 2006

well you could make two php pages like so:

[b]index.php[/b]
[code]
.....
<body>
<form action="config.php" method="post">
Change Ip to: <input type="text" name="ip">
<input type="submit" name="submit" value="Submit New Ip">
</form>
....
</body>
[/code]

[b]
config.php[/b]
[code]
<?
if(isset($_POST['submit'])) {
$ipfield = $_POST['ip'];
echo "Current Ip is:" . $ipfield . ".";
}
?>

[/code]

that is close but i want it to physically edit the file.

so before edit
[code]
<?php

$site_url= "http://127.0.0.1/";

?>[/code]

after edit

[code]
<?php

$site_url= "http://192.168.0.100/";

?>[/code]

it is a config file for a script I'm working on

makeshift_theory · September 17, 2006

That script would physically edit the file, it takes the ip from a input box and changes the variable on the config page. I may not be be completely understanding of what you need but I think from what you just posted it should work for your needs.

Ben Phelps · September 17, 2006

i need it to open the file change http://127.0.0.1/ to what ever the user inputs and save the file for later use, not just change the var. when the script is being used

makeshift_theory · September 17, 2006

with that said
[code]
fopen('config.php');
fwrite($ipaddress);
fclose();

[/code]

Ben Phelps · September 17, 2006

what do i do with that ??? I'm sorry i don't understand php that well

makeshift_theory · September 17, 2006

use php.net as a reference for function usage. fopen, fwrite, and fclose open files write text ot files and close an active file.

Ben Phelps · September 17, 2006

i have a script that writes the ip to the config.php but it writes to the end of the document. I need it to write in a certain place.

[code]<?php

$script_url = "it needs to write here" ;

?>not here[/code]

Here are the scripts i use now.

get.php

[code]<html>
<head>
<title></title>
</head
<body>
<form action="write.php" method="post">
<p align="center"><strong>Script Installer </strong><br>
Where is the script at :<br>
<input type="text" name="ipfield">
<br>
<input type="submit" name="submit" value="Install">
<br>
Ex. <strong>http://www.thepchs.com/script/</strong></p>
</form>
</body>
<html>[/code]

write.php

[code]<?php
$filename = 'config.php';
$somecontent = "$ipfield";

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'a')) {
echo "Cannot open file ($filename)";
exit;
}

// Write $somecontent to our opened file.
if (fwrite($handle, $somecontent === TRUE) {
echo "Cannot write to file ($filename)";
exit;
}

echo "Success, wrote $somecontent to file $filename";

fclose($handle);

} else {
echo "The file $filename is not writable";
}
?> [/code]

config.php

[code]<?php

script_url = "";

?>[/code]

You could use this script (untested).
[code]
<?php
if(isset($_POST['newip'])) {
$newip = $_POST['newip'];
$oldtext = file_get_contents('config.php');
$newtext = preg_replace('/http:\/\/(.*)\//', "http://".$newip."/", $oldtext);
$fp = fopen("config.php", "w");
fwrite($fp, $newtext);
fclose($fp);
} else {
?>
<form method="post" action="<?php echo $_SERVER['SCRIPT_URI'] ?>">
IP: <input type="text" name="newip" /><br>
<input type="submit" value="submit" />
</form>
<?php } ?>[/code]

Ben Phelps · September 17, 2006

THANK YOU VERY MUCH ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D

Ben Phelps · September 17, 2006

Ben Phelps · September 17, 2006

redarrow · September 17, 2006

update.php
[code]
<?php

if(isset($_POST['newip'])) {
$newip = $_POST['newip'];
$oldtext = file_get_contents('config.php');
$newtext = preg_replace('/http:\/\/(.*)\//', "http://".$newip."/", $oldtext);
$fp = fopen("config.php", "w");
fwrite($fp, $newtext);
fclose($fp);
header("location: thankyou.php");
}
?>
[/code]

form.php

[code]
<html>
<body>
<form method="post" action="update.php">
IP: <input type="text" name="newip" /><br>
<input type="submit" value="submit" />
</form>
</body>
</html>
[/code]

thankyou.php

[code]
<html>
<body>
thank you
</body>
</html>
[/code]

or easer
[code]
<?php
if(isset($_POST['newip'])) {
$newip = $_POST['newip'];
$oldtext = file_get_contents('config.php');
$newtext = preg_replace('/http:\/\/(.*)\//', "http://".$newip."/", $oldtext);
$fp = fopen("config.php", "w");
fwrite($fp, $newtext);
fclose($fp);
echo "thank you";
exit;
} else {
?>
<form method="post" action="<?php echo $_SERVER['SCRIPT_URI'] ?>">
IP: <input type="text" name="newip" /><br>
<input type="submit" value="submit" />
</form>
<?php } ?>
[/code]

GeorgeMoney · September 17, 2006

Or if you want them to press a 'confirm' button:
[code]<?php
if(isset($_POST['newip'])) {
if(isset($_POST['confirm'])) {
$newip = $_POST['newip'];
$oldtext = file_get_contents('config.php');
$newtext = preg_replace('/http:\/\/(.*)\//', "http://".$newip."/", $oldtext);
$fp = fopen("config.php", "w");
fwrite($fp, $newtext);
fclose($fp);
} else {
echo "Are you sure about that? <form method='post' action='$_SERVER[SCRIPT_URI]'><input type='hidden' name='newip' value='$_POST[newip]' /><input type='submit' name='confirm' value='confirm' /></form>";
}
} else {
?>
<form method="post" action="<?php echo $_SERVER['SCRIPT_URI'] ?>">
IP: <input type="text" name="newip" /><br>
<input type="submit" value="submit" />
</form>
<?php } ?>[/code]
