README

This is a TYPO3 extension that allows an editor to run configured server-side scripts via a backend interface. It will add a dropdown menu to the toolbar of the backend to select the script to run.

Installation

Use composer to add the extension as a dependency: composer require grossberger-georg/run-script.

Configuration

Important: The webserver must have nohup and bash installed and available to the user running in the PHP process in its $PATH variable.

Creating a script

The executing script will change its working directory to the root path of the project and export all available environment variables before execution. Example: in a composer-mode installation with default options, the script ./vendor/bin/typo3 scheduler:run would start the scheduler.

The script is not escaped, quoted or in any other way changed. It is executed as it is given.

Any valid bash command is a valid script, so this is allowed too: if [[ ! -f /tmp/hello ]]; then echo Hello > /tmp/hello; sleep 200; rm /tmp/hello; fi

If the scripts points to a file, make sure it has the executable bit set.

If it is a file and has an EXT: prefix it will be resolved to an absolute path. An EXT: prefix somewhere in between will not be resolved. The script EXT:shop/Resources/Private/Scripts/import.sh will work, but if [[ ! -f /tmp/importing ]]; then EXT:shop/Resources/Private/Scripts/import.sh; fi; will not.

Only one instance of a script can run at a time. EXT:run_script will create a lock and inform a user if there is already a process running that script.

Setup scripts to run

A script is two parts: a key as well as an array with at least two entries: a name and the bash command to execute. They are added to the global TYPO3_CONF_VARS:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['run_script']['<KEY>'] = [
    'label'  => '<LABEL>',
    'script' => '<SCRIPT>',
];

Use an extensions ext_localconf.php or the AdditionalConfiguration.php file to add scripts. A simple demo is included which can be activated with in the extension settings with the option Enable demo scripts

The key should follow the TYPO3 convention of tx_myext_function.

Inside the array, the following options are available:

If reloadBackend is given, the number is the count of seconds, after which the backend is reloaded, after a script finished. This is useful if a script changes the data visible in the backend, like a product importer.

Permissions

By default, administrators see all scripts. This can be disabled in the extension settings with the option Disable always access for administators. Then the access must be granted with TSConfig settings, like to editors.

Editors can only execute scripts which are in a comma separated list in the TSConfig key tx_runscript.allowed. The key of the configuration array must be in this list for a script to be executable.

Example:

# Always allow those two:
tx_runscript.allowed = tx_shop_import_products, tx_shop_export_orders

# Editors with Backend Group 3 can also run this one:
[like(","~backend.user.userGroupList~",", "*,3,*")]
    tx_runscript.allowed := addToList(tx_shop_clean_expired_carts)
