I have the following code:

print $node->field_carousel_1[0]['filepath'];

What I would like to do is changing the 1, and use a variable instead.

Do you have any idea how I would be able to do this?

What I am aiming for is using a variable to create a looping function to print "field_carousel_1," "field_carousel_2," "field_carousel_3," etc.

  • Check there isn't already a similar question, first. It is probable somebody already asked a similar question, and the answer is a feature present in PHP. – kiamlaluno Jan 26 '12 at 14:39

    I'm afraid I still have to disagree. Sam is dealing with fields, and there may very well have been field API functions for his use case. You don't know unless you ask. – Chapabu Jan 26 '12 at 15:36

You can just change the 1 to your particular variable in the loop.

Example:

foreach ($values as $k => $v) {
  print $node->field_carousel_ . $v . [0]['filepath'];
}

That should output the values you need.

  • Thanks for replying, i actually get a syntax error on the print line there, any ideas why? – Sam Warren Jan 26 '12 at 14:45
  • I've edited my answer...try it now, it's only really an example and you may have to modify it for your use case. It also may be slightly wrong as I'm on my phone at the moment ;-) – Chapabu Jan 26 '12 at 14:55
  • It doesn't work, as PHP will try to access $node->field_carousel_, convert it to a string, and concatenate it with $v. It should also return you a syntax error. – kiamlaluno Jan 26 '12 at 21:48
