    Form processing : storing strings in arrays

    I am trying to write a function that "captures" the names of .jpeg files from a web form and compare these to the jpeg files that I have stored in my local directory.

    Can anyone clue me in? How do I pass the inputs from a HTML form into a sorted array? I know that image filenames are to be stored as strings in char array but I am not sure how to do it.

    In a html form
    -----------------
    Images:

    Image1.jpg
    Image2.jpg
    Image3.jpg
    .......
    .......
    Image?.jpg
    ----------------

    Code:
    void scanDirectory(void) / / / / / / / / / / 
    {
       char *Images =  
       field->getValue("Images");
       if (Images == NULL) errorTerminate  
       ("No image field found in the form!     
          \n ");
       if(strncmp(Images,"Images", 9)==0)
    	errorTerminate("Image names  
            not specified");
    
       else ??
    }
    D.A.C

    Read from stdin. That is an aspect of CGI programming that many are surprised with at first, to read from a form or other such GET function all you have to do is read from stdin with whatever works best. I would suggest fgets.

    -Prelude
    My best code is written with the delete key.

    I hear that gets works best for CGI due to its enhanced security features.

    Hope is the first step on the road to disappointment.

    It depends on who you are talking about when it comes to security.

    Now it all depends on whether your form is using the method GET or POST. For full details check out:

    Please don't reply to age old threads, this conversation was over some 5 months ago.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
