calling classes and objects

[Trium918]

<?php

class FileStorage {

	function FileStorage($path, $shoutLog = false) {
		$this->shoutLog = $shoutLog;
		$folder = 'logs';
		if (!is_dir($folder)) $folder = '../' . $folder;
		if (!is_dir($folder)) $folder = '../' . $folder;
	
		$this->path = $folder . '/' . $path . '.txt';
	}
$show_path= new FileStorage;
echo $show_path ->FileStorage();
?>

What is the correct way to call the class FileStorage's object? I am trying to test the class to see if it is working.

$show_path = new FileStorage();
echo $show_path->FileStorage($path);

 

That should work.. Make sure you do it outside the class definition, or inside another function within that class that is called externally.

 

Hopefully that helps

I'm assuming that's not your entire class definition. Does your complete class have a __construct() method? If not, the FileStorage() method may be used as the constructor and be called twice. Also note that the echo statement isn't going to do anything since FileStorage() doesn't return a value.

Here is the complete class. I am trying to figure out why this class isn't writing to the log file.

Based on a cursory look, the class doesn't have any properties.

http://www.php.net/manual/en/language.oop5.properties.php

 

However, the class is attempting to use properties which haven't been defined.

 

$this->shoutLog = $shoutLog;

The method 'FileStorage' is the constructor for the class. It has two parameters: $path and $shoutLog. The $path parameter is required. When you instantiate the class you must pass at least that first parameter. It looks like it is used as a sub-path within the folder 'logs' for storing the log files.

I am having problems writing to the file called logs.

And if there are problems in instantiating/setting up the class you will have problems with anything else within the class. I can't believe you are not getting errors since you are not even passing the required parameter to the class.

Have you attempted to fix the class (and the references to the class)? If so, it may help to post the updated code.
