Select multiple users?

[trhooper123]

Hello, Awesome plugin! I am using it for a school project where we have to assign pdf docs to 3 specific users. I found the lines in the php code and edited them to show three drop down boxes but it makes all three boxes the same whenever I save. Any tips or ideas??

<p><input type="file" name="upf_file" id="upf_file" /></p>
<p class="label"><label for="upf_user1"><?php _e('Select a user', 'user-private-files');?></label></p>  
<select name="upf_user1" id="upf_user1">
    <?php
    $users = get_users();
    $upf_user1 = get_post_meta($post->ID, 'upf_user1', true);
    foreach ($users as $user) { ?>
        <option value="<?php echo $user->ID;?>" <?php if ($upf_user1 == $user->user_login) echo 'selected="selected"';?>><?php echo $user->user_login;?></option>
        <?php
    }
    ?>
</select>
<p class="label"><input type="checkbox" name="upf_notify" value="1"> <label for="upf_notify"><?php _e('Notify User', 'user-private-files');?></label></p>   
<p class="label"><label for="upf_user2"><?php _e('Select a user', 'user-private-files');?></label></p>  
<select name="upf_user2" id="upf_user2">
    <?php
    $users = get_users();
    $upf_user2 = get_post_meta($post->ID, 'upf_user2', true);
    foreach ($users as $user) { ?>
        <option value="<?php echo $user->ID;?>" <?php if ($upf_user2 == $user->user_login) echo 'selected="selected"';?>><?php echo $user->user_login;?></option>
        <?php
    }
    ?>
</select>
<p class="label"><input type="checkbox" name="upf_notify" value="1"> <label for="upf_notify"><?php _e('Notify User', 'user-private-files');?></label></p>   
<p class="label"><label for="upf_user3"><?php _e('Select a user', 'user-private-files');?></label></p>  
<select name="upf_user3" id="upf_user3">
    <?php
    $users = get_users();
    $upf_user3 = get_post_meta($post->ID, 'upf_user3', true);
    foreach ($users as $user) { ?>
        <option value="<?php echo $user->ID;?>" <?php if ($upf_user3 == $user->user_login) echo 'selected="selected"';?>><?php echo $user->user_login;?></option>
        <?php
    }
    ?>
</select>
<p class="label"><input type="checkbox" name="upf_notify" value="1"> <label for="upf_notify"><?php _e('Notify User', 'user-private-files');?></label></p>

it's not clear if the functionality is working when you save but in case it does and you want to save the selection you can look into something like this solution: http://stackoverflow.com/questions/10957926/saving-dropdown-menu-selection-in-a-cookie

It will let you select three things, then when you click update on the page it changes all three to the same user.

I was able to get it working with choosing 3 users and having it save them successful. The only thing left is to have it display it for the users. I am only able to get it to show for the first user.

Here is the code for creating the three separate users

<p><input type="file" name="upf_file" id="upf_file" /></p>
<p class="label"><label for="upf_user1"><?php _e('Select a user', 'user-private-files');?></label></p>  
<select name="upf_user1" id="upf_user1">
    <?php
    $users = get_users();
    $upf_user1 = get_post_meta($post->ID, 'upf_user1', true);
    foreach ($users as $user) { ?>
        <option value="<?php echo $user->ID;?>" <?php if ($upf_user1 == $user->user_login) echo 'selected="selected"';?>><?php echo $user->user_login;?></option>
        <?php
    }
    ?>
</select>
<p class="label"><input type="checkbox" name="upf_notify" value="1"> <label for="upf_notify"><?php _e('Notify User', 'user-private-files');?></label></p>   
<select name="upf_user2" id="upf_user2">
    <?php
    $users = get_users();
    $upf_user2 = get_post_meta($post->ID, 'upf_user2', true);
    foreach ($users as $user) { ?>
        <option value="<?php echo $user->ID;?>" <?php if ($upf_user2 == $user->user_login) echo 'selected="selected"';?>><?php echo $user->user_login;?></option>
        <?php
    }
    ?>
</select>
<p class="label"><input type="checkbox" name="upf_notify" value="1"> <label for="upf_notify"><?php _e('Notify User', 'user-private-files');?></label></p>
<select name="upf_user3" id="upf_user3">
    <?php
    $users = get_users();
    $upf_user3 = get_post_meta($post->ID, 'upf_user3', true);
    foreach ($users as $user) { ?>
        <option value="<?php echo $user->ID;?>" <?php if ($upf_user3 == $user->user_login) echo 'selected="selected"';?>><?php echo $user->user_login;?></option>
        <?php
    }
    ?>

And for saving the three users

// if invalid $post object or post type is not 'userfile', return if(!$post || get_post_type($post->ID) != 'userfile') return;

$user_info = get_userdata($_POST['upf_user1']);
add_post_meta($post_id, 'upf_user1', $user_info->user_login);
update_post_meta($post_id, 'upf_user1', $user_info->user_login);

$user_info = get_userdata($_POST['upf_user2']);
add_post_meta($post_id, 'upf_user2', $user_info->user_login);
update_post_meta($post_id, 'upf_user2', $user_info->user_login);

$user_info = get_userdata($_POST['upf_user3']);
add_post_meta($post_id, 'upf_user3', $user_info->user_login);
update_post_meta($post_id, 'upf_user3', $user_info->user_login);

And here is where I am stuck where it creates the file list

'userfile', 'meta_key' => 'upf_user1', 'meta_value' => $current_user->user_login, 'orderby' => 'date', 'order' => DESC );
