Edit .php page with a form

[driveflexfuel]

I am trying to create an options form that will change php variable within a configuration file. If anyone knows how to do this it would be great help.

Config.php looks like this

//language
$language = 'EN';

//Currency
$currency = 'USD'

//Page Title
$title = "Welcome - Home Page"

Options.php the submission form

<form>
Language <select name="language">
            <option value='EN'>English</option>
            <option value='SP'>Spanish</option>
            <option value='FR'>French</option>
         </select>
         <br/>
Currency <select name="currency">
            <option value='USD'>US Dollar</option>
            <option value='EUR'>Euro</option>
            <option value='GBP'>British Pound</option>
         </select>
         <br/>
Page Title <input type="text" name="title" />
<br/>
<input type=submit name=submit />
</form>

you'd have to do:

<form action="config.php" action="post">
Language <select name="language">
            <option value='EN' name="EN">English</option>
            <option value='SP' name="SP">Spanish</option>
            <option value='FR' name="FR">French</option>
         </select>
         <br/>
Currency <select name="currency">
            <option value='USD' name="USD">US Dollar</option>
            <option value='EUR' name="EUR">Euro</option>
            <option value='GBP' name="GBP">British Pound</option>
         </select>
         <br/>
Page Title <input type="text" name="title" />
<br/>
<input type=submit name=submit />
</form>

Now, we create "config.php".

$lang = $_POST['language'];
$cur = $_POST['currency'];
$title = $_POST['title'];

Done.

I don't think you understood what I meant. Im guessing you thought i just needed to pass variables between pages with post but that is not the case.

config.php is a page filled with variables that are called by many different pages.

Options.php is a page in a admin panel where they can permanently change the variables found in config.php.

Are you asking about different users each one able to pick their own options?

If that’s the case, you will want to save those options into the user information table so they can be retrieved or changed when needed.

this might be a lot easier for you:

I'd do it with mySQL, much easier.

If you have a lot of values that are never changed or changed very infrequently, I would think that using a config file would be faster and simpler than many queries, though normal day to day tasks I would definitely use SQL.

I think everyone missed what i was getting at so ill show you what I found. This code opens my config.php file collects the variables, displays them in the form. When the form is submitted it writes the new values in. It took me 4 hours to find someone to help on this subject so share this code with everyone and get it on more forums.

<?php
$handle = fopen('config.php', 'r+');
$contents = fread($handle, filesize('config.php'));
$config_array = array( 
    '\$DB_host' => $_POST['DB_host'], 
    '\$DB_user' => $_POST['DB_user'], 
    '\$DB_pass' => $_POST['DB_pass'], 
    '\$DB_name' => $_POST['DB_name'] 
);


// get values 
foreach($config_array as $from => $to)
{ 
    if(preg_match("/$from\=\'(.*?)\';/", $contents, $matches)) 
    { 
         $config_values[$from] = $matches[1]; 
    } 
    else 
    { 
         $config_values[$from] = ''; 
    } 
} 
// now config-values has all the prior values of config.php :
//    $config_values['\$DB_host'] = 'localhost';    for example

        $DB_host = $config_values['\$DB_host'];
        $DB_user = $config_values['\$DB_user'];
        $DB_pass = $config_values['\$DB_pass'];
        $DB_name = $config_values['\$DB_name'];
        
        if (isset($_POST['submit'])){

            // this line creates config-values as an empty array. no changing ;)
            $config_values = array();
                            
            foreach($config_array as $from => $to) 
            { 
                $contents = preg_replace("/$from\=\'(.*?)\';/", "$from='$to';", $contents); 
            } 
            
            fclose($handle);
            $handle = fopen('config.php', 'w');
            fwrite($handle, $contents);
            fclose($handle);
            echo '<meta http-equiv="refresh" content="0;url=index.php" />';

don't see why you didn't like the second option...

BTW, you should use the header function, not a meta redirect.
