   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.

     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?

     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.

   Hi,
   Good day!
   Would like to know how to set a white paper in my blog post article to download it with add email address from the visitor.

     Hi Ikram,

     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.

   is it possible to create style css file in this site specific plugin?

     Yes, they will.

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

   The plugin generated 3 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

   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?

    I need to create a custom post type to add some major functionality to my site so is the plugin better or the child theme and its functions.php?

    Thanks!

      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.

    Hi there,
    You WP Beginners are rock. and I want to thank you for your Struggles for us.
    Now come to the point. I have installed an theme and in that theme, there is an function that is showing wp toolbar for guests, I have tried so many times to find this function in theme files to remove this, but i can’t. So please help me to remove that toolbar, that is showing to every visitor with wordpress logo and wordpress’s own link to their website. Screen Shot is attached.

    Does something like this work for plugins too? Im finding that I am making a few changes to plugins that I add to my site….many times deleting certain lines of code I dont want. I’m assuming that after I update that plugin, all my changes will be erased. How can I avoid this?

    Hi, thanks for the post. I’m getting an error when I activate the plugin for some reason:

    Parse error: syntax error, unexpected '*’, expecting identifier (T_STRING) on line 9

    Any ideas what I’ve done wrong?

    Thanks!

      Hi Elizabeth,

      There is an unexpected asterisk sign in the code on line 9 which is blocking the php script. Edit the file again and copy the code exactly as it is shown above. Make sure that you don’t copy line numbers in the code click on the Copy button at the top right corner of the code snippet box

      .

    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.

    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.

      Hey Steven,

      I know the feeling! I’m far from a expert with wordpress and I pretty much live on google searches and this site trying to learn. I know a little bit and was able to get this to work. Send me your email and I’ll send you the steps with screenshots. I havent tested putting actual code into the plugin so we’ll see if that works….but I was able to see the newly created plugin on my admin page

    Thank you for the great advice and simple how-to instructions. I easily created a Site-Specific WordPress Plugin for my site and enabled shortcodes for widgets. Now I have less worry when changing themes, and I didn’t need to install another plugin. Again, thanks!
