I can't get this to work at all!! So frustrated. I don't want the user to enter any values but numbers... ctype_digit only gives me and noone else errors. So i'm using is_integer... can somebody figure it out?

I have a php page that will simply take some information from the user and output the time it will take for the train to travel the specified distance. But if the answer 2.5 is printed... it really means 2 hours and 30 minutes. I understand that the bcdiv can fix this somehow? Any ideas as to how to use it with what I have?

Not only do I have this problem... but I can't figure out how to transfer the hours into minutes as well... if it prints 2.5 I want it to say 2 hours and 30 minutes, how would I go about doing this with the modulus operator?
-
I don't get an error if use either of the two, but it doesn't skip to the else statement no matter what. So if its filled out correctly, it still doesn't work.
-
I did this and I get this error... Fatal error: Call to undefined function: ctype_digit() in /Users/100075255/Sites/PassengerTrain.php on line 21
-
Another question... I know that ctype_digit($var) will keep users from entering characters other then digits.. but how would I input that into my code... I tried, and I got it wrong?

Why won't my else if statement execute for my second radio button?
-
I always seem to forget about isset.
-
How can I say if(click on submit button){this happens!}??
-
Same thing happens.
-
When the form is submitted with everything filled out... it won't print out the info() function... well... it does but without the stored information... why is this?

I've really got to get more sleep...

Hmm... thats weird...Why would it do that then?

Seems easy... but its not working... any reasons?

The reason the other variables are there is that I don't forget what they are worth later as I have to do more to it... however, its still not giving any variables when the submit is hit, its like it just refreshes?
-
Thats ingenious!That code won't tell if they filled anything out, it will only tell if they submitted the form. Since you are using isset, the variables will still be set, they just might be empty. I normally just have a variable that keeps track of errors.$errors = "";if ($fname == "") $errors .= "Please fill in a first name<br>";if ($lname == "") $errors .= "Please fill in a last name<br>";...if ($errors == ""){ //no errors}else echo $errors;... things are always this simple... I don't know why I don't clue in?
-
ok... I'll play with this for a while. Thanks!!
-
I'm trying to do it but I don't think I'm understanding...
-
How can I set my code up so that if the user does not put in anything for last name but there is something in first name... it will still say please go back to put your information in and vice versa. If both are put in and everything is fine... then the order is complete statement is executed? I can only figure out half of it, but the rest I can't get it to work.

Subquery Help Needed
in SQL
Posted
I'm having trouble retrieving data from the database. basically this is what I have to do...use a subquery and find all the employs names and salaries (over the entire company) that earn more tha the average salary of the research department.The main table is called emp and it contains a column called sal. There is another table called dept and it contains a column called dname.This is what I come up with but it doesn't work...
Does anybody see the problem?
