[RESOLVED] $_SESSION variable to make int

kingdm

Hello again mates,

I wonder if how can I make my variable (from a form) to be passed as an int. Because whenever I saved it on the database the exact value doesn't appear.

My question is where do I placed the B[/B] syntax.

Is it in:

a. session_register('age');

b. $SESSION['age'] = $POST['age'];

I really appreciate your reply mates.

$_SESSION['age'] = intval($_POST['age']);

Thanks for the reply buddy.

By the way what is intval()? what does it differ from int?

Also buddy, is this value "09222352123" is applicable in my database row having a type of int(20).

And then my code in calling this is like what you said.

$_SESSION['contact_num'] = intval($_POST['contact_num'];

// contact_num = "09222352123"

Is this correct? Sorry if I'm bothering in asking too much question, I'm just new here in PHP. 🙂

Read the PHP manual on [man]intval/man. Personally, I would just cast to int.

That depends on the range of int in your database.

It sounds like you want to store it as a string, not an int, but just validate that it consists of digits (which can be done with [man]ctype_digit/man).

Yup, thanks now I know. By the way buddy, I have this script now this time I want to check if my SESSION variables did pass on my multi-page form. I created a script that will print all of them. Is my syntax correct?

echo "$_SESSION['username']" . "$_SESSION['password']" . "$_SESSION['emailadd']" . "$firstname" . "$midname" . "$lastname" . "$city_add" . "$city_mobile" . "$citizenship" . "$gender" . "$religion" . "$cstatus" . "$mbday" . "$dbday" . "$ybday";

I'm having an error here in this line as my browser pinpoints:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in C:\xampp\htdocs\pamscorp\form2_processing.php on line 47

Remove all the double quotes as you do not need them.

kingdm

It works. I guess I need to learn a lot more in PHP, even those double quotes fooled me 😕 .

Thanks for the reply amigo. Case solved. Thanks. 🙂
