Advanced if statement

Myrkul

Well mabye its not advanced.. but It is to me heh.

I have 20 fields that I want to display (based on the value of it in the db either 0 or 1).. but I want to display all of them that have a value of 1 and not display the ones with a value of 0.

I am not sure how to do this in an if statement.. sure I code out every possible combination.. but there has to be an eaiser way?

Any tips would be appreciated.

Hi there. I assume the values are all in an array? If they aren't, put them in one, it will be much easier 😉 Then use a foreach loop. Have a look at this: http://www.php.net/manual/en/control-structures.foreach.php

here's an example too 🙂

foreach($data_array as $key=>$value) {

if($value == 1) {

// Display it
} else {

// Don't display it
}
// End the foreach
}

Hope that helps!

I am not completly clear on that script.. what exactly is the $key?

I see how it works.. but I don't see how it if checks the next field...

But there is another complication.. each field is numbered C1 through C20 something.. like i said I want to display them if they are true (read: values of 1s).. then depending on the field I want to echo something else

so if say C2 C12 and C19 are all 1s I want to display them like:

Blah2, Blah12, Blah19

Not:
C2, C12, C19

foreach($data_array as $key=>$value)

This should help explain this part: $data_array is obviously your array in which you have the stored values... $key is the variable all the values pertaining to 1's and/or 0's will be stored. Which means if in your array if you have C12,C13,C14 and they are all 1's and want to be printed to the screen, that their actual values are stored in the $key variable which ultimately is the variable printed to the screen.

Hope that helps.
