Cannot write a file

Question

I need to write file by pushing retrieved data in to text file. But the file not write. This is the relevant code section. This code section contains within function in controller.

            $filename = "form_ipn.log";
            $fh = fopen($filename, "a") or die("Could not open log file.");
            fwrite($fh, date("d-m-Y, H:i")." - $name;\n") or die("Could not write file!");
            fclose($fh);

I have created a file inside a controller->adminhtmlfolder. Is there any problem with this folder regarding writing privileges? Or is there any problem on my code?

Answer 1

Converting comments to answer

yes might be privileges issue as you have not mentioned path of file so it will be default to controller->adminhtml folder

Yo can specify by like

Mage::getBaseDir('media'), Mage::getBaseDir('var');

For example $filename = Mage::getBaseDir('media').DS."form_ipn.log"; it will write your file in media folder on root
