TYPO3 Core

// check the write permissions of the following directories first

// this jumps in as the first message during installation process to force the user to fix this at first

$writeDirectories = array(

'fileadmin',

'typo3conf',

'typo3temp',

'uploads',

// saves all directories with insufficient permissions

$missingWritePermissions = array();

foreach ($writeDirectories as $directory) {

if (!is_writable($PATH_site . '/' . $directory . '/')) {

$missingWritePermissions[] = $directory;

}

}

// show warning, if one of the directories lacks write permissions

if (count($missingWritePermissions)) {

$markers = array(

'styleSheet' => $stylesheet,

'javascript' => $javascript,

'title' => 'Insufficient permissions',

'content' => '

<p>

To work properly, the following directories and their contents must be writable for the user,

under which the web server is running:

</p>

<ul>

<li>

' . implode('/</li><li>', $missingWritePermissions) . '

</li>

</ul>

<p>

On most systems, this can be achieved by executing the following commands:

</p>

<pre>' .

implode(array_map(

function($directory) use ($PATH_site) {

return 'chown -R 777 ' . $PATH_site . '/' . $directory . '/<br />';

},

$missingWritePermissions

)) . '</pre>

',

);

} else {

// display the "Install Tool is locked" message

$markers = array(

'styleSheet' => $stylesheet,

'javascript' => $javascript,

'title' => 'The Install Tool is locked',

'content' => '

<p>

To enable the Install Tool, the file ENABLE_INSTALL_TOOL must be created.

</p>

<ul>

<li>

In the typo3conf/ folder, create a file named ENABLE_INSTALL_TOOL. The file name is

case sensitive, but the file itself can simply be an empty file.

</li>

<li class="t3-install-locked-user-settings">

Alternatively, in the Backend, go to <a href="javascript:top.goToModule(\'user_setup\',1);">User tools &gt; User settings</a>

and let TYPO3 create this file for you. When you\'re finished, you can also visit

<a href="javascript:top.goToModule(\'user_setup\',1);">User tools &gt; User settings</a> and delete the file from there.

</li>

</ul>

<p>

For security reasons, it is highly recommended that you either rename or delete the file after the operation is finished.

</p>

<p>

As an additional security measure, if the file is older than one hour, TYPO3 will automatically delete it.
