Warning: Missing argument

Well, this is only a warning, so it doesn’t affect how the plugin works. However, if you want to fix it, you can open up instructions.php, and change line 601 from this:

$path = plugin_dir_url();

to this:

$path = plugin_dir_url(__FILE__);

Alternatively, you can just shut off error messages in your WordPress install.

I can’t replicate this issue, though – so I’m not 100% sure that will work.

Thank you, I’ll leave it as it is now, does not bother me. ??

Good work! good plugin!

@angutir, What plugins are you using because I have the same warning…

Hugh, if you have the same warning, just setting the line:

define('WP_DEBUG', false);

in your wp-config.php file should solve the problem.

actually it was showing up, even though define('WP_DEBUG', false); was set to false.

Well your server settings could also be set to show notices and warning messages. (The WP_DEBUG setting is only for WordPress, not the entire server.) So if it’s still showing, that’s probably what it is.

You’re not stating *exactly* what your message is, Hugh – and I’m wondering if the message is even related to my plugin (since you asked “what plugin are you using?” – this is the board for *my* plugin, and as I stated above, I can’t replicate this, even with my error_reporting turned on). It would be helpful to know what messages you’re getting, since I can’t see the issue myself.

Actually the warning text goes away if I deactivate the plugin… I figured that I could just implement the features as a custom content type and do no front end theming…. conceptually the content is supposed to only be accessed through the admin pannel anyway…

Here is the error I get (personal info replace with ~), which happens to be exactly the same as cited above:

Warning: Missing argument 1 for plugin_dir_url(), called in /home/~/wordpress/wp-content/plugins/back-end-instructions/instructions.php on line 601 and defined in /home/~/wordpress/wp-includes/plugin.php on line 599

I was asking @angutir which plugins they were using because it is logical that there could be a plugin conflict between your plugin and another plugin. So, in an effort to compare plugin sets we are using, I was asking “what plugins are they using?”

The error only shows up on the admin page for your plugin. wordpress/wp-admin/edit.php?post_type=instructions

Is it a variable name conflict?

Basic Google Maps Placemarks
Google XML Sitemaps
contact form 7
And the theme Daisho

And the warning it is the same, but as the plugin author say “it doesn’t affect how the plugin works” i don’t try to fix it because doesn’t bother me.

Yea, I am not using any of those plugins. I wonder if it is an incomplete array or syntax based issue based on the the part of the warning saying “Missing argument 1″… of course I have not looked the code for myself

Again, Hugh, as stated above, it’s a warning, not an error, so it doesn’t affect how the plugin works. And, per the solution I provided above:

you can open up instructions.php, and change line 601 from this:

$path = plugin_dir_url();

to this:

$path = plugin_dir_url(__FILE__);

That *should* fix it.

That does work. Thanks!
