对cgic的理解——name选项

void HandleSubmit();// 提交
void Name();
void ShowForm();//页面的显示
int cgiMain()

submission of the form. 提交表单*/

}
void HandleSubmit()// 提交
{
Name();
}
void Name()
{
char name[81];
char age[81];
cgiFormStringNoNewlines("name", name, 81);//函数的功能就是取的并显示由用户输入的name
cgiFormStringNoNewlines("age", age, 81);//函数的功能就是取的并显示由用户输入的name
fprintf(cgiOut, "Name: ");
cgiHtmlEscape(name);//将得到的name值显示到屏幕
fprintf(cgiOut, "age: ");
cgiHtmlEscape(age);
fprintf(cgiOut, "<BR>\n");
FILE * file_fa = fopen("a.txt","w+");
fwrite(name,strlen(name),1,file_fa);
fwrite(age,strlen(age),1,file_fa);
}
void ShowForm()//页面的显示
{
fprintf(cgiOut, "<!-- 2.0: multipart/form-data is required for file uploads. -->");

//fprintf(cgiOut, "<p>Text Field containing Plaintext\n<p>");
fprintf(cgiOut, "<input type=\"text\" name=\"name\">Your Name\n");
fprintf(cgiOut, "<input type=\"text\" name=\"age\">Your age\n");
// fprintf(cgiOut, "<input type=\"text\" name=\"age\">");
fprintf(cgiOut, "<input type=\"submit\" name=\"1saveenvironment\" value=\"Save Environment\">\n");
//name 必须和cgiFormSubmitClicked("1saveenvironment")中函数参数一致
fprintf(cgiOut, "</form>\n");
}
功能将得到的name和age写到a.txt中
