I'm setting up a Coppermine gallery integrated with vBulletin, but this means users will never see Coppermine's registration terms. My company needed to make sure users accepted some terms of use--in a nutshell, that we can reuse the pics they upload elsewhere.

The mod works in the same manner as uploading photos to Facebook: the user is asked to check a box when they upload photos and, if the box wasn't checked, the upload fails. The terms are a custom item in the language file; they are not the ones agreed to during registration.

If you want to add this to a future version, what's missing is translating the messages into other languages and adding a configuration option to turn this behavior on and off (but I assume that's trivial? I don't know, I just started hacking Coppermine this morning...). I'd love to see this in a future version because that means I don't have to maintain more custom code on my site

I'm a UNIX guy so here's the patch against Coppermine 1.4.19. I removed the terms I put into lang/english.php because they're specific to my organization.

Thanks for your readiness to share. Sadly, the majority of our users is not familiar with diffs, so we'd appreciate it if you could create the usual instructions (edit foo.bar, find bla, replace with whatever).

[divestoclimb]

Okay here goes: (I'm leaving out the comments)

Open lang/english.php

Find the line

Code: [Select]

$lang_errors = array(Just before the next line with a ");", add this line:

Code: [Select]

'tc_not_agreed' => 'In order to upload images, you must agree to the gallery\'s <a href="terms.php" target="_blank">Terms and Conditions</a> by checking the box on the upload form.',
Find the line beginning with $lang_register_disclaimer, then after the next line with a "EOT;", add this:

Code: [Select]

$lang_terms = <<<EOT
[your terms and conditions go here]
EOT;
Find the line that looks like this:

Code: [Select]

if (defined('UPLOAD_PHP')) $lang_upload_php = array(Just before the next line with a ");", add this line:

Code: [Select]

'tc_agree' => 'By checking this box, I agree to the gallery\'s <a href="terms.php" target="_blank">Terms and Conditions</a>.',
Now close english.php and create a file called terms.php. Put the following in it:

Code: [Select]

<?php

**********************************************/

define('IN_COPPERMINE', true);
define('REGISTER_PHP', true);

require('include/init.inc.php');
require('include/mailer.inc.php');

pageheader($lang_register_php['term_cond']);
starttable(-1, $lang_register_php['term_cond']);
echo <<<EOT
        <tr>
                <td class="tableb">

EOT;
echo $lang_terms;

echo <<<EOT
                </td>
        </tr>
EOT;
endtable();
pagefooter();
ob_end_flush();

?>

Now open upload.php.

Find the line that begins with "function text_box_input..." and look for the next line that starts with a } (no spaces before it). After that line add the following:

Code: [Select]

function checkbox_input($text, $name) {
    echo <<<EOT
<tr>
    <td width="40%" class="tableb">&nbsp;</td>
    <td width="60%" class="tableb" vlaign="top">
<input type="checkbox" id="check_$name" name="$name" />
$text
    </td>
</tr>

EOT;
}

Now search for these lines:

Code: [Select]

                    // Call the hidden input funtion.
                    hidden_input($element[0], $element[1]);
                    break;
And after them, add this:

Code: [Select]

case 5 :

    checkbox_input($element[0], $element[1]);
    break;

Look for this:

Code: [Select]

        create_form($data);
And add this before it:

Code: [Select]

        array_push($data, array($lang_upload_php['tc_agree'], 'agree', 5));

Look for this:

Code: [Select]


            // Add the control device.
            $form_array[] = array('control', 'phase_1', 4);
And add this before it:

Code: [Select]

    array_push($form_array, array($lang_upload_php['tc_agree'], 'agree', 5));

Look for this:

Code: [Select]

            // We have error support.
            $error_support = 'TRUE';

        }
And add this after it:

Code: [Select]

if($_POST["agree"] != "on") {
    pageheader($lang_error);
    msg_box($lang_error, $lang_errors['tc_not_agreed'], $lang_continue, "upload.php", "100%");

    // Create the footer and flush the output buffer.
    pagefooter();
    ob_end_flush();

    // Exit the script.

    exit;
}

And that's it!

I made the edits to both both upload.php and english.php but got an "illegal form creation" error (luckily I backed up the original files).

I double checked the edits I made.  They seemed to follow the instructions.  I'm using version 1.4.19.  Is it a fault with the code listed in the "do-this-do-that" post (immediately above this)?

Are there any other ways to add an upload check-box for T's and C's?

[divestoclimb]

I'm new to the software but I'm not familiar with that error message.

I may be able to help if you:
- copy and paste the exact error message you're seeing
- copy and paste the sections of PHP code that you modified. If there was a mistake in my instructions that should help me notice and correct it.

Divestoclimb,

I've just re-edited the upload.php and english.php files to include your modifications.  The code works fine.  I'd missed out "case 5" in this bit

case 5 :

          checkbox_input($element[0], $element[1]);
          break;

Sorry for raising a false alarm.  Thank you for providing you code too 

Kindest Regards,

Midas/

[divestoclimb]

Excellent! Glad to see you worked it out.
