[RESOLVED] Updating a config.php file

Robert_B_

Hello gang,

I'm trying to update my config.php file thru a form and I find this code and it works but I would like a litter help in modifing it. Right now when I submit the form the field don't show the changes until I refresh the page manually. There anyway the I can show the changes in the form when I submit the form with out have to refresh the page?

Here's the form page

// include the varibles in this file

include("config.php");

?>

Thank you all in advance. 
Robert


<form action="<?php echo $php_SELF?>">
<input type="text" name="dbhost" value="<?php echo"$dbhost" ?>">
<input type="text" name="dbuname" value="<?php echo"$dbuname" ?>">
<input type="text" name="dbpass" value="<?php echo"$dbpass" ?>">
<input type="text" name="dbname" value="<?php echo"$dbname" ?>">

<input type="hidden" name="moveon" value=2>
<input type="submit" name="Submit">
</form>

<?php

//  GET the varibles from the form above

$moveon=$_GET[moveon];
$dbhost=$_GET["dbhost"];
$dbuname=$_GET["dbuname"];
$dbpass=$_GET["dbpass"];
$dbname=$_GET["dbname"];



//Following code overwrites myvaribles.php4 with the new data

if($moveon==2) {
           $fh=fopen("config.php","w");
           fwrite($fh,"<?php\n");
           fwrite($fh,"\$dbhost = \"$dbhost\";\n");
           fwrite($fh,"\$dbuname = \"$dbuname\";\n");
           fwrite($fh,"\$dbpass = \"$dbpass\";\n");
           fwrite($fh,"\$dbname = \"$dbname\";\n");
           fwrite($fh,"?>");
           fclose($fh);
     }

Here's the config.php file

$dbhost = "AAAAAAA";
$dbuname = "BBBvv";
$dbpass = "CCC";
$dbname = "GGGGGG";

Put this

//  GET the varibles from the form above

$moveon=$_GET[moveon];
$dbhost=$_GET["dbhost"];
$dbuname=$_GET["dbuname"];
$dbpass=$_GET["dbpass"];
$dbname=$_GET["dbname"];



//Following code overwrites myvaribles.php4 with the new data

if($moveon==2) {
           $fh=fopen("config.php","w");
           fwrite($fh,"<?php\n");
           fwrite($fh,"\$dbhost = \"$dbhost\";\n");
           fwrite($fh,"\$dbuname = \"$dbuname\";\n");
           fwrite($fh,"\$dbpass = \"$dbpass\";\n");
           fwrite($fh,"\$dbname = \"$dbname\";\n");
           fwrite($fh,"?>");
           fclose($fh);
     }

after

include("config.php");

Kudose thanks for your fast response. I try that way before and the problem is the when I first load the page the fields will show blanks till I submit the new variables and I will like to read the variables before I submit the new ones.

Thank you again

Kudose it is a fix I did not get it first. This is the complete code in case that can help someone else

THANK YOU

$dbname=$_GET["dbname"];

Hello again,
I have one more question about this. I have more variables in the same document that I do not want to change, How can I avoid the other information from deleting? I was thinking getting the value and the submiting them in a hidden field but what about comments the I have in the config.php file?

Thanks again

Kudose

If you use "w" for file writing, you will lose all data in the file.

You could just hard code the values you don't want to change.

i.e.

<?php 
           $fh=fopen("config.php","w");
           fwrite($fh,"<?php\n");
           fwrite($fh,"\$dbhost = \"$dbhost\";\n");
           fwrite($fh,"\$dbuname = \"$dbuname\";\n");
           fwrite($fh,"\$dbpass = \"$dbpass\";\n");
           fwrite($fh,"\$dbname = \"$dbname\";\n");
           fwrite($fh,"\// this is a comment about the next line.\n");
           fwrite($fh,"\$something= \"something something something\";\n");
           fwrite($fh,"?>");
           fclose($fh); 
?>
