   Is it possible to add code snippets like Google Analytics Code, Adsense code in Site Specific Pliugin. Or only possible to add codes we generally put in functions.php file.

   I mean, is it possible to add codes in site-specific plugin what we generally put in Header.php file.

     You can do that if you would like, you can also use the insert headers and footers plugin.

   hi
   Thanks for this tuto
   however is there a way to make this plugging(not to be visible) not in plugging list and also in a specific folder (not wp-content folder) ?

   • Tor-Bjorn Fjellner

     Actually yes, there is:
     Instead of placing the plugin in …/wp-content/plugins/ you put it in …/wp-content/mu-plugins/ (You may have to create that directory, if it’s not there yet.

     Plugins that are placed in mu-plugins are ALWAYS run, so the only way to deactivate a MU plugin (MU currently is construed as “must use”) is to delete it (or remain the directly mu-plugins to something else…).

   Hi I tried to do the Site-specific plugin, but it is not working, I get this message “The package could not be installed. No valid plugins were found.

   Plugin installation failed.”
   What do I do?

   Yanıtla

   • WPBeginner Support

     Hi Judith,

     This usually means that the plugin header information is incorrect. You can try again and make sure that your plugin header is exactly in the format displayed in the tutorial.

       I get this same error. I have tried maybe 10 times. Uploaded through admin and on FTP. Cannot get it to upload. I am using TextEditor to paste the code. Notice several things you don’t mention in the post that I wonder could be an issue. First, won’t let me save the file as .php. I have to save it as .php.rtf OR .rtf then go back and rename the file after it is saved.
       Second, not sure what you mean by making sure the format for the plugin header is exactly the same. Should the line number be in there? If so, I can’t get that to work. If I copy and paste with the line numbers, the green vertical line doesn’t show up and there is no space between the line numbers and the code. Or am I supposed to just copy the code (without the line numbers)? Either way, I’ve tried everything I can with my current Textedit application and it will not work.
       Any ideas? I can send you screen shots of exactly what I have if you would like

         Hi Jonathan,

         You will need to save file as .php. Please use a different text editor on Windows you can use Notepad or download Notepad++. On Mac, you can use TextEdit or download and install TextWrangler.

         You don’t need to copy and paste line numbers.

         In my case the issue was that the file had Unicode encoding. Changing it to ANSI fixed the issue.

     You can do that with the pro version of WPForms. You will need at least Plus plan for that. After users enter their email address and click submit you can redirect them to the download page.

     Yes, they will.

     You should create a child theme and put your modifications there instead of in the original theme.

   I believe best approach to add custom code to site is child theme. No matter if we need to customize theme or not. I mad a practice to always use child theme even if there is no customization. This habit saved my time & effort many times. I dont think it is good to create extra plugin for such customization.

   I believe in minimum use of plugin no matter how simple you created one.

    Which is better, site-specific plugin or Child Theme? or both?

    Thanks!

    Yanıtla

    • Josh

      The thing is, is that you’re creating the plug-in yourself, using the functions the same exact way. So the answer to your question would be that neither is better, because you should be using them WITH each other.

    • Josh

      Think of the site-specific plug-ins as functions that are independent of your theme.

    I tried naming the new folder as you did in the example but I got an error that said something in the way of you cannot use a name like this. This Instruction may be helpful to some – but it is very difficult and confusing to me and does not help at all. As I said – you need to explain this down to the fine details or otherwise these tutorals will not help. The name of this site is wp BEGINNER – and that is what I am. You project these tutorals to the more experienced.

    I guess I will have to start going elswhere to get beginners instructiions because, most of time, wp beginner is not helpful – it is more like a techs only club.

17. Steven Denger

    How do you get to the /wp-content/plugins/yoursitename-plugin/ in wordpress and upload a file there? I am lost on the first line of instruction. You guys always assume that we know these things in your instructions but they are not clear enough.

    I went to cpanel and opened up the wpcontent > plugins – and it shows a list of plugins – but I am lost from this point. How do I go about uploading a file in here? I am a beginner – and you guys seem to always explain things like your instructing experienced techs. I am not but I go to WP Beginner to try to learn. It is usually difficult to follow your instructions and I end up having to go somewhere else in google search to find things explained down to a beginners level.
    If you want to be more helpful try breaking things down a little more simple.

    Hi again. I’ve been reading through all of the comments above and, while some show your answer and resolution to the problem, many don’t. So it’s hard for me to learn from how others resolved their problems! Anyway, here’s what I’m wondering: if by following the instructions in this post to create a folder within my “plugins” folder, how will I be able to see my new site-specific plugin file?
    For example, I followed the instructions to create a folder called susansinthegarden-plugin. Then I put my plugin code in a file called susansinthegarden-plugin.php. I can’t see the plugin when I go to plugins on my dashboard.
    Is this because the new plugin text file exists in a sub-folder under “plugins”? I can’t figure out what I’m missing but really need to resolve this. Is there anyone out there who can help me? Thanks so much!

        Hi,
        What is a plugin header and how do I format it?

        Yanıtla

        • WPBeginner Support

          Hey Emy,

          The plugin header is the part that tells WordPress that this file should be treated as a plugin. It also tells WordPress the name of the plugin, version, and other information.

          In the code shown above, the header part begins right after the first line and ends at line 5. It contains plugin’s title and description.

    • Susan

      OK, I resolved my program. Not being a code-writer, I didn’t realize that there was a separate header to wrap around the code I was borrowing. Duh. Thanks for your help.

34. Alan Shapiro

    This is a really useful post–thank you! Perhaps someone else asked this and I just missed it in all the comments, but: will a site-specific plugin override a function that is in the theme’s functions.php? For instance, if there is a “remove_action” in the functions.php, will the same “add_action” in the plugin take precedence?

    Yanıtla

    • WPBeginner Support

      Both functions.php file and site-specific plugin are treated as plugins. Functions.php file loads after plugins but they do not have precedence over eachother. This is why using the same function in both files can cause unexpected results. The best way to override pluggable code is by using hooks and filters.

      Actually we do not recommend editing plugins and themes from WordPress admin area. Instead, we would recommend editing your plugins in a text editor via FTP client. This way in case of an error you would be able to quickly fix it without losing access to admin area for too long.

    Three years later this post is still giving – It’s changed the way I think about customising wordpress – Thank you!

    I tried this today and created a a site-specific-plugin with code to hide the wordpress menu bar for non-admins, and to add my latest post to a ‘Current issue’ menu item. Both worked perfectly.

    But the third snippet I added to the plugin failed to work. When I copied the code to the child theme’s functions.php it worked as expected.

    Can you explain why this would happen?

    I’m trying to modify the effect of the plugin “Restricted Site Access” by allowing access to more than a single page. The code I tried in my site specific plugin and the functions.php was:

    //
    add_filter( ‘restricted_site_access_is_restricted’, ‘my_restricted_check’ );
    function my_restricted_check( $is_restricted ) {
    global $wp;
    if (
    $wp->query_vars[‘pagename’] == ‘contact’ ||
    $wp->query_vars[‘pagename’] == ‘subscribe’ ||
    $wp->query_vars[‘name’] == ‘aplr-2013-volume-21-number-2’
    )
    $is_restricted = false;

    return $is_restricted;
    }

    Any advice or comment would be welcome. I’m confused!

    You can try and fit your modifications in site-specific plugin by using filters. However, since you had to edit specific files we doubt that all your edits can be implemented in a site-specific plugin using filters. In that case you should make those changes into a child theme. All your custom CSS should also go into your child theme’s stylesheet. You can also use your site-specific plugin to enqueue a custom stylesheet.

    Hmm, looks like my last post went missing while registering for this annoying disqus plugin.

    Anyways:
    At first I’d like to thank you for sharing this information.

    Secondly I do have several questions regarding this post.

    1) Is it possible to also make site specific plugins for other .php’s where I’ve added some codes?
    Such as front-page.php post-page.php and post-archives.php

    2) Is it possible to do something like this for .css codes?
    I run genesis as framework(Parent theme) and a child-theme that I’ve downloaded.
    Now since there are no grand-child theme’s in wordpress I’ve made my alterations in the child-theme’s folder

    This includes a lot of different .css edits, Is there a way to make site specific .css files/plugins like this, so I can maintain the origional child-theme (and perform an update if any updates are released)?

    3) When I create a site-specific plugin to change the footer and activate it, I will see both the origional footer and my own footer on the site.
    Is there a way to go around this?

    My plugin looks like this:

    Once again thank you for sharing this information on site-specific plugins, and I hope to hear soon from you guys.

      Hi Chelsey. Consider this guide:

      Go to “File Manager”. It will take you to “/public_html” directory. Click on “wp-content >> plugins” . This is where you will “create” a folder called “yoursitename-plugin”. After that, create a file using some text editor(notepad++), paste the code given above and save the file as “yoursitename-plugin.php”. Upload it to “yoursitename-plugin” folder and activate it in your wordpress admin area. Easy as that!

    yes you can use it for multiple functions.

49. WPBeginner Staff

    Your code seems to be correct. Here is what you can do:

    Make sure you have saved the plugin file in the /wp-content/plugins/ directory.

    Make sure that your plugin file name is correct. We recommend using yoursitename.php format. For example if your domain name is black-circles then your plugin file name should be black-circles.php

    • SteveMTNO

      I originally had the plugin file (bc-plugin.php) in its own directory called blackcircles/wp-content/plugins/bc-plugins. That didn’t work.

      Then I tried moving the bc-plugin.php file from that folder to the blackcircles/wp-content/plugins folder. Still doesn’t show up in my admin panel.

      Do I have to “enable” it first before it shows up or something?

      • WPBeginner Staff

        If the file is correctly placed in your plugins folder then you will see it in your WordPress admin area under Plugins. If you see your plugin there, then you will have to click on the activate link below the file to activate the plugin.

        Did you try renaming the file to something else?

          Tried renaming it 3 times – none of them show up….

          I must be doing something wrong (or not doing something that I should be doing)…

        • SteveMTNO

          So can I use this one site-specific plugin for multiple functions, or is it best to do something similar to this for each one?
