Installation

Installation is rather easy: just activate the plugin, it will create the database table it needs to work on its own.

Using the Plugin

We leave the no-brainer part to learn something interesting now: how to implement the plugin in your theme.
Basically all you need are 2 functions:

  1. mfp_the_link();
  2. mfp_display();

mfp_the_link will display an “Add this post to your favorite post list” link wherever you call it. Best practice of course is to add the function anywhere INSIDE your WordPress loop. That will create the add link for each post.

You can pass up to two parameters when calling mfp_the_link().
These are: add_link and remove_link.
The syntax is euqal to many wordpress core functions:

mfp_the_link("add_link=add me please&remove_link=remove me please");

This will replace the default link names with the ones you provide. If you want you can add markup as well:

mfp_the_link("add_link=<span class='add_this'>add me please</span>");

mfp_display will display the list of favorite posts anywhere you like. No WordPress loop required here.
So you can put the list in your sidebar, footer, main content area etc.

Of course you can pass parameters here as well. Calling the function without parameters will create an unordered list: each list item will contain a link to the post and a “remove link”.
The default classes added are:

  • ul class: mfp_favorites
  • link class: mfp_link
  • remove link class: mfp_remove_link

So you don’t like my classes? Or you want to display the items in <div> and <p> instead of <ul> and <li>?
Here are the parameters you may change:

  • title : Default is no title
  • display : Default is “list” -> you may change it to “div”
  • remove_link : Text for remove link, Default is “remove”
  • class : Class for ul/div , defaul is “mfp_favorites”
  • link_class : Class for the post link, default is “mfp_link”
  • remove_link_class : Class for remove link, default is “mfp_remove_link”
  • order_by : Order of items, default is ID, you can change that to any field name of the wp_posts table: some examples would be “post_title”, “post_author”, “post_date”. Get the full list at the WordPress Codex.

Some examples:

// Add a h3 title
mfp_display("title=<h3>Favorite Posts</h3>")

// Display as Div with different class names
mfp_display("display=div&class=class_1&link_class=class_2");

// Order by post Title & different remove link text
mfp_display("order_by=post_title&remove_link=up up and away");

Another option is to pass the ID of a user to the function. This way it will display another users favorite post list. you can do that by apending the ID as a seperate parameter. The following example would retrieve the posts of user 13 from the database:

mfp_display("order_by=post_title",13);

One of the best options to use this function would be to show it on the authors page of a user. Just insert the ID of the user dynamically ;)

Another option to display the posts is through the widget added in version 1.2.

Thats it. If you encounter any problems, please tell me via contact form or comments. I would also be glad to hear suggestions for improvements, be it in functionality, usability or code wise.

Have a nice day ;)

    Hello Kriesi.

    I’m getting a little problem.
    I uploaded the plugin and activated it. How can i call it to my singlepost.php for example? I want to show it in the end of each post but i can’t get it.

    The same for that sidebar show off list.

    Can you help please?

    Regards,
    Paulo

  2. Kriesi says:

    Thanks for the kind words, hope the plugin serves all of you well.

    @ adonis: without the login its hard to identify the user and therefore nearly impossible to display the list stored in the database. Only solution I could think of is using cookies to store the data instead of the database, but this would somehow limit the usefulness of the plugin.

    Accessing the list from more than one computer would be impossible and whenever the cookie would be deleted the list would be gone as well.

    @Paulo: If you want to display the add post link on a single page just write the function call mfp_the_link() in your templates single.php.

    And to display the whole list in your sidebar, just place the function call mfp_display() in your sidebar.

    Great plugin! I used the is user logged in function in wordpress to display a link that displays to the user that they must login to add to favorite. :) Thanks!

  4. Frank says:

    I cannot get this to work for non-admins. It works perfectly fine when i’m logged in as an admin, but when I log in as a subscriber, [level 0] it doesn’t show the ‘Add this to my favorite posts’ link. Any ideas why?

  5. Kriesi says:

    Hey Frank,
    A am afraid, I have no Idea why this problem occurs at your website, since the plugin works fine on every blog I testet it.

    Only reason I could think of is another plugin that changes user permissions. What you could try is deactivate all other plugins and see if the link is displayed then.

    btw: you got a nice website, i just started watching heroes and love it. Watched Season 1 in a marathon session of 2 days ;D

  6. Matt says:

    Great plugin… thanks Kreisi!

    The add/remove works great but when I went to put the favorites code I get a php syntax error…

    Parse error: syntax error, unexpected ‘=’ in /home/*******/public_html/wp-content/themes/sgrl/single.php on line 12

    using code

    It only appears to error when calling mfp_display. I run the latest version of wordpress. any ideas or suggestions?

    Thanks again :)

  7. Matt says:

    … comment strip the php code…

    mfp_display(”display=div&class=class_1&link_class=class_2″);

    -or-

    mfp_display(”order_by=post_title&remove_link=up up and away”);

  8. Kriesi says:

    I think the problems are the double quotes. its a strange thing, but WordPress keeps changing them into fancy quote-like characters when I write articles, even if I use the html code. If you don’t copy paste the code and instead write it by hand you shouldn’t get any errors.

  9. Chuck says:

    Thank you so much for the plugin. I love it!

    Question for you. When I’m on a page with multiple posts and I favorite a post towards the bottom. The page refreshes and goes to the top. Is there away to anchor the post?

    Thanks again!

  10. Kriesi says:

    Hi Chuck,

    I can add this to the to-do list for the next version, seems like a pretty good idea. If you want it here and now, its rather easy to accomplish. Lets say your WordPress loop automatically generates the anchors for each post (id=”post-1″, id=”post-2″ etc) as most themes do. Just open the fav_me.php file, and check line 84 and 86. These lines create the add and remove links.

    Just change favorite-post=$post_ID to favorite-post=$post_ID#post-$post_ID

    same for the second link, and an anchor is added to each add and remove link.

  11. Chuck says:

    Thanks so much! I just made the changes, works perfectly. BTW, here’s the site that I’m using your plugin…

    http://foodgawker.com/

    One odd thing, when I tried to float:right the add and remove link span or div, the image wasn’t clickable in IE, worked fine in FF and Safari. I could see the link in the bottom of the browser on rollover, but couldn’t click it. I had to push it right using padding… very odd. But it’s either my issue or just typical IE bug. Thanks again.

  12. gMk says:

    Very nice work.

    Be great if you could get a count of the number of times a post has been made a favourite by all users.

  13. Cool Raker says:

    Great plugin, I’m using it at my newly launched site http://coolraker.com as a kind of personal wish list of a reader’s favorite items. I also second the request for tracking the number of times a post is added, that would be very useful.

    How to display user’s favorites on her/his author page with her/his profile? And anyone can see

  15. Andrew says:

    All my thought and dreams are crushed…
    Ok, so I go to a post to add a favorite, I go to my profile, its there….yay.

    but, when I go to another browser (w/o loging in) I don’t see any favorites.
    But, when I log in again, its there.
    (the two browsers are FF and IE)

    So, whats the problem? & how do you store the favorites?

    Shoot me an email, thanks!

  16. Kriesi says:

    The data is stored in your database and can only be retrieved if you are logged in, since the plugins has to identify which persons favorite posts should be displayed.

  17. Andrew says:

    Ok, well.
    Now I have this other problem.
    I really want to show each users favorites, separately.
    (On the users profile page).

    Right now it shows the favorites of the user that is logged in, not the one whos profile it is.
    Do you know whats going on?
