[helloise]

i need to use filename further in the code i now have:

$filename = $this->getMsisdn().".png";

if (!file_exists(sfConfig::get('sf_upload_dir') . '/rainbowcode/images/profilepics/'.$filename))

            { 

                $file_in = "Rainbow-code-1_blck.jpg";

                $using_default_pic = 1;           

            }

           

            if ($using_default_pic == 1)

            {

                $using_default_pic = 0;

                echo "filename before rename ".$file_in;

                $filename = rename($file_in,$this->msisdn."jpg");

Don't you mean:

$filename = rename($file_in,$this->getMsisdn()."jpg");

$filename will just have TRUE or FALSE based on whether it succeeded or not.

 

Are you sure you want to just rename it or make a copy?

[helloise]

thanks  i fixed it but still not working

 

echo "filename before rename ".$file_in;  //gives: Rainbow-code-1_blck.jpg

$filename = rename($file_in,$this->getMsisdn());

echo "calling resize image after rename: ".$filename.".jpg".'<br />';  //here $filename is empty???

 

yikes please help?

thank you

$filename is the result of rename, which returns TRUE or FALSE depending on whether it was able to rename the file or not... if it's blank that means it probably failed.

[helloise]

thank you but can you help me with this please and show me how to achieve this so that i rename Rainbow-code-1_blck.jpg to $this->getMsisdn().".jpg"

and assign $filename the value of $this->getMsisdn().".jpg"  because i need to use $filename further on in my code

 

thank you

[dcro2]

$file_in = "Rainbow-code-1_blck.jpg"; 
$filename = $this->getMsisdn().".jpg";

if(!rename($file_in, $filename)) echo "Failed to rename image.";

You do understand that as soon as you run this once, the code will fail if you try to run it again, right? It won't be able to find 'Rainbow-code-1_blck.jpg' because it's been renamed. That's why I was suggesting you make a copy of it (under that new name). To do that just replace the rename call with copy.

yikes maybe i must explain:

 

a user registers a profile online and if he DOES NOT upload a profile pic i must use a default pic which is: "Rainbow-code-1_blck.jpg";

if he DOES upload a pic the profile pic will be saved as : $this->getMsisdn().".jpg" and i carry on with my code as per usual

 

BUT

 

if $this->getMsisdn().".jpg does not exist(user did not upload a profile pic) i must use Rainbow-code-1_blck.jpg BUT further along my code i need the file name to be

$this->getMsisdn() AND the picture is the actual default picture just renamed....

 

hope this makes sense???

[dcro2]

Yeah, it makes sense, but only if you copy the default profile pic. If you rename it you won't be able to use it again after the first time someone doesn't upload a pic... because it won't exist as that file name anymore.
