c cgi script display results below html form
Hi,
I'm implementing a simple c script from a book as a server cgi-bin executable. I would like the result of the script to be displayed in the same web page from which it is called Example: The html page that hosts the form and calls simplest.cgi <FORM ACTION = "cgi-bin/simplest.cgi" METHOD="POST"> <p><i>Search info from this form using cgi script</i></p> <br /> <p>Title <INPUT TYPE="TEXT" SIZE=20 NAME="titre"></p> <br /> <p><INPUT TYPE="SUBMIT" VALUE=" Search "> </FORM> simplest.cgi looks like this #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAXL 132 int main(int arg, char *argv[]){ /* Phase 1 variables */ int lg ; char ligne[MAXL]; printf ("Content-type: text/html\n\n"); printf ("<HEAD><TITLE>Résultat de la recherche</TITLE>"); printf ("</HEAD><BODY bgcolor=white>"); printf ("<H1><CENTER>Résultat de la recherche</CENTER></H1>"); /* Phase 1 Extraction des paramètres */ lg = atoi (getenv("CONTENT_LENGTH")); fgets(ligne, lg+1, stdin); printf("<B>Paramètres :</B> %s<P>\n", ligne); return 0; } Can I include the printf function to show its argument directly on the htmlpage above? Thanks Pascal |
Re: c cgi script display results below html form
What i think of but i'm not sure of how efficient it is, it's to insert a tag comment in the html below the form, from the cgi c script, open that html file, look for the comment text and display results there.

Yes, but not closing the main HTML tags will quite likely give your browser the shits. -- Ian Collins |

I guess you meant "closing the BODY tag", as he didn't even open an HTML tag |
