# Grav Problems Plugin
|

|
|
|
`Problems` is a [Grav](http://github.com/getgrav/grav) Plugin and allows to detect issues.
|
|
|
|
This plugin is included in any package distributed that contains Grav. If you decide to clone Grav from GitHub, you will most likely want to install this.
|
|
|
|
# Installation
|
|
|
|
Installing the Problems plugin can be done in one of two ways. Our GPM (Grav Package Manager) installation method enables you to quickly and easily install the plugin with a simple terminal command, while the manual method enables you to do so via a zip file.
|
|
|
|
## GPM Installation (Preferred)
|
|
|
|
The simplest way to install this plugin is via the [Grav Package Manager (GPM)](http://learn.getgrav.org/advanced/grav-gpm) through your system's Terminal (also called the command line). From the root of your Grav install type:
|
|
|
|
bin/gpm install problems
|
|
|
|
This will install the Problems plugin into your `/user/plugins` directory within Grav. Its files can be found under `/your/site/grav/user/plugins/problems`.
|
|
|
|
## Manual Installation
|
|
|
|
To install this plugin, just download the zip version of this repository and unzip it under `/your/site/grav/user/plugins`. Then, rename the folder to `problems`. You can find these files either on [GitHub](https://github.com/getgrav/grav-plugin-problems) or via [GetGrav.org](http://getgrav.org/downloads/plugins#extras).
|
|
|
|
You should now have all the plugin files under
|
|
|
|
/your/site/grav/user/plugins/problems
|
|
|
|
> NOTE: This plugin is a modular component for Grav which requires [Grav](http://github.com/getgrav/grav), the [Error](https://github.com/getgrav/grav-plugin-error) and [Problems](https://github.com/getgrav/grav-plugin-problems) plugins, and a theme to be installed in order to operate.
|
|
|
|
# Usage
|
|
|
|
`Problems` runs in the background and most of the time you will not know it is there. Although as soon as an issue is caught, the plugin will let you know.
|
|
|
|
`Problems` checks for the following common issues:
|
|
|
|
| Check | Description |
|
|
| :-------------- | :-------------------------------------------------------------------------------- |
|
|
| Apache | `mod_rewrite` is enabled if you are running an Apache server. |
|
|
| PHP Version | PHP version being run by the server meets or exceeds Grav's minimum requirements. |
|
|
| PHP Modules | PHP GD library is installed. |
|
|
| | PHP Curl library is installed. |
|
|
| | PHP Ctype library is installed |

|
|
| | PHP OpenSSL library is installed. |
|
|
| | PHP Mbstring library is installed. |
|
|
| Essential Files | `.htaccess` file in Grav's root directory. |
|
|
| | Checks that all the files in the `bin/` folder are exectuable. |
|
|
| | `/cache` folder's existence and verifies that it is writeable. |
|
|
| | `/logs` folder's existence and verifies that it is writeable. |
|
|
| | `/images` folder's existence and verifies that it is writeable. |
|
|
| | `/assets` folder's existence and verifies that it is writeable. |
|
|
| | `/system` folder's existence. |
|
|
| | `/tmp` folder's existence. |
|
|
| | `/user/data` folder's existence and verifies that it is writeable. |
|
|
| | `/user/images` folder's existence. |
|
|
| | `/user/config` folder's existence. |
|
|
| | **Error** plugin is installed in `/user/plugins/error`. |
|
|
| | `/user/plugins` folder's existence. |
|
|
| | `/user/themes` folder's existence. |
|
|
| | `/vendor` folder's existence. |
|
|
|
|
If an issue is discovered, you will be greeted with a page that lists these checks and whether or not your install passed or failed them. Green checks mean it passed, and a red x indicates that the there is something amiss with the item.
|
|
|
|
Problems uses the cache as refresh indicator. That means that if nothing has changed anywhere, the plugin will just skip its validation tests altogether.
|
|
|
|
If a change is caught and the cache is refreshed, the plugin will loop through its validation tests and making sure nothing is out of place.
|
|
|
|
`Problems` gets also triggered if any fatal exception is caught.
|
|
|
|
# CLI Command
|
|
|
|
Problems 2.0 comes with a handy CLI command so you can run the checks at any time
|
|
|
|
```bash
|
|
bin/plugin problems check
|
|
```
|
|
|
|
You should see some output like this:

|
# Extending Plugins
|
|
|
|
You can also extend the problems plugin via the `onProblemsInitialized()` event. The event includes an array of Problems. Simply create your own Problems class that extends the `Grav\Plugin\Problems\Base\Problem` class and add it to the array.
