  • Should I sanitize EVERY form variable passed along?

    - by Camran
    I have a form with many fields... The action is set to a php page which queries mysql... Should I sanitize with mysql_real_escape_string every single variable? Or can I ignore sanitizing drop-lists and radios for instance? Also, besides mysql_real_escape_string, what else should I do to prevent attacks? Thanks

  • Query on the scope of local variables in C

    - by darkie15
    All, Consider the following code: void func(void) { int a; printf ("%d", a); } int main(int argc, char **argv) { int a = 3; func(); printf("%d", a); } According to my understanding, the output should be: <junk value><3> Can anyone please confirm my understanding? My basic query is, does the compiler refer to the outer scope for a variable that has been declared but not defined? Regards, darkie

  • Reset SQL variable inside SELECT statement

    - by Jason McCreary
    I am trying to number some rows on a bridge table with a single UPDATE/SELECT statement using a counter variable @row. For example: UPDATE teamrank JOIN (SELECT @row := @row + 1 AS position, name FROM members) USING(teamID, memberID) SET rank = position Is something like this possible or do I need to create a cursor? If it helps, I am using MySQL 5.

  • Use the keyword class as a variable name in C++

    - by Leif Andersen
    I am having trouble writing C++ code that uses a header file designed for a C file. In particular, the header file used a variable name called class: int BPY_class_validate(const char *class_type, PyObject *class, PyObject *base_class, BPY_class_attr_check* class_attrs, PyObject **py_class_attrs); This works in C as class isn't taken as a keyword, but in C++, class is. So is there anyway I can #include this header file into a c++ file, or am I out of luck? Thank you.

    - by John
    Hey guys, a quick question, I have data of the following sort: Ticker _ Date _ Fem Analyst (dummy 1 if true) AA _ 04/2001 _ 1 AA _ 04/2001 _ 1 AA _ 04/2001 _ 1 AA _ 05/2002 _ 1 AA _ 05/2002 _ 1 AA _ 07/2002 _ 0 AA _ 04/2003 _ 1 and so on.. What I want to receive is the following: Ticker _ Date _ Number of fem analyst AA _ 04/2001 _ 3 AA _ 05/2002 _ 2 AA _ 07/2002 _ 0 AA _ 04/2003 _ 1 So an easy counting algorithm that allows me to count for the number of analysts per company per month (the date is in 01/04/2002 format but I also have a month count variable which can be used too) Any ideas?

  • Extern variable at specific address

    - by AndiNo
    Using C++ and GCC, can I declare an extern variable that uses a specific address in memory? Something like int key attribute((__at(0x9000))); AFAIK this specific option only works on embedded systems. If there is such an option for use on the x86 platform, how can I use it?

  • PHP while(variable=mysql_fetch_assoc) - explanation

    - by Petr
    Hi, I have been working with C# so this is quite strange for me: while($variable=mysql_fetch_assoc) I have not been able to look up in PHP manual how it works. I guess that in each loop it advances to next element of assoc.array. But what is this generally called in PHP? I am just not used to see '=' in loop condition.
