When exit() is unsuitable

[bluns]

Hi all, i have 3 upload forms and a script to check mime types to make sure uploaded files are images.

//check picture1 MIME type 
if (!in_array($picture1_type, array('image/gif', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/x-png'))) 
{ 
    $picture1_error = TRUE; 
    echo 'Problem: File must be an image'; 
    exit();
} else  { 
    $picture1_error = FALSE; 
    echo $picture1_name.' uploaded successfully<br/>'; 
} 

//check picture2 MIME type 
if (!in_array($picture1_type, array('image/gif', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/x-png'))) 
{ 
    $picture2_error = TRUE; 
    echo 'Problem: File must be an image'; 
    exit();
} else  { 
    $picture2_error = FALSE; 
    echo $picture2_name.' uploaded successfully<br/>'; 
} 

//check picture3 MIME type 
if (!in_array($picture1_type, array('image/gif', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/x-png'))) 
{ 
    $picture3_error = TRUE; 
    echo 'Problem: File must be an image'; 
    exit();
} else  { 
    $picture3_error = FALSE; 
    echo $picture3_name.' uploaded successfully<br/>'; 
} 

 

Problem is that, if the user only wishes to upload 1 file or upload no files at all, the exit command will stop the whole script. Is there any way around this? I want users to have the option of uploading nothing at all if they do not want to.

Well, the first question that comes to mind is: if they don't want to upload, why are they on your upload page? 😉

The second is: where's the upload code?

Finally, assuming that this is all good && well, I guess you could just set the three error messages and then assume that if you collected all 3 they hadn't wished to do an upload?

thanks for helping dale

i found my problem 😛

I should have put my upload code within the {} instead of further down in the script 🙂
thanks
