Hi everyone! I am having some difficulty with my code here. I wrote a prgraom that is supposed to receive a non-determined number of fields from an HTML form and return their values back to a browser. I feel like I am almost finished but when I open up the html document on the web the input isn't coming out right.Do you think its the debug code? Thanks for the help!!! Here is my code:
#include <iostream>
#include <cstdlib>
#include <string>
#include <cstring>
#include <ctype.h>
using namespace std;
/* Structure */
struct FORM
{
char name[65];
char data[65];
};
/* Function Prototypes */
int equalcount(string);
FORM * create_array(int);
void getData(string, FORM *);
string param(string, FORM *);
/* Main Function */
int main()
{
string qs(getenv("QUERY_STRING"));
cout << "Content-type:text/html\n\n";
// string qs = "name=Katy&gift=iPod&gender=girl&reason=goodallyear";
cout << "Returned data from web: " << qs << endl;
int equal;
equal = equalcount(qs);
FORM *dyn_array;
dyn_array = create_array(equal);
getData(qs, dyn_array);
cout << "<html><head>";
cout << "<title>color</title></head>";
cout << "<body>";
string gift = param("gift", dyn_array);
string name = param("name", dyn_array);
string gender = param("gender", dyn_array);
string reason = param("reason", dyn_array);
cout << "<html>" << endl;
cout << "<head>" << endl;
cout << "<title>Your Christmas Wish List!</title>" << endl;
cout << "</head>" << endl;
cout << "<body>" << endl;
cout << "<font color=\"#FF9933\">" << endl;
cout << "<body bgcolor=\"#FFFFCC\">" << endl;
cout << "<center>" << endl;
cout << "</center>" << endl;
cout << "<b>Dear Santa, </b><BR>\n";
cout << endl;
cout << "<b>The one thing I want most for Christmas is " << gift << ". </b><BR>\n";
cout << "<b>The reason I really deserve " << gift << " is because I have been a very good " << gender;
cout << "most of the year! </b><BR>\n";
cout << "<b>I also deserve this gift because " << reason << ".</b>,\n";
cout << endl;
cout << "<b>Love," << name << "</b><BR>\n";
cout << "</font></body>" << endl;
cout << "</html>" << endl;
system("PAUSE");
return 0;
}
int equalcount(string qs)
{
int index = 0, equal = 0;
for (index; index < qs.length(); index++)
{

{

}
}
return equal;
}

{

array = new FORM[equal];
return array;
}
void getData(string qs, FORM *dyn_array)
{
int x = 0;
int y = 0;
int i = 0;
// cout << "debug with qs.length: " << qs.length() << "< br>";
while( x < qs.length())
{
while (isalnum(qs[x]))
{
dyn_array[i].name[y] = qs[x];
// cout << "debug with name[" << y << "]: " << dyn_array[i].name[y] << "< br>";
y++;
x++;
}
dyn_array[i].name[y] = '\0';
// cout << "name: " << dyn_array[i].name << endl << "< br>";
y = 0;
while (!(isalnum( qs[x])))
{
x++;
}
{
dyn_array[i].data[y] = qs[x];

}
}
string param(string input, FORM *dyn_array)
{
int index=0;
string ans;
for(index=0; index<20; index++)

}This is the first page on the web:
The gift you want most for Christmas:
My name on Santa's List:
Gender(boy/girl):
Why do you deserve this gift?
and then a submit button allows the user to input their info. Now when they hit submit their information should be outputted saying:
Dear Santa,
The one thing I want most for Christmas is <<the gift input<<
The reason I really deserve << the gift input << is because I have been a very good << gender input << most of the year! I also deserve this gift because << reason input<<
