[RESOLVED] Double foreach - possible?

duckyB

I'm pretty sure not, but I'd rather avoid having double results from doing two separate loops and joining them later.

I've tried a few methods, but nothing. I've come across something like this before, but this time I actually need to care.

There's probably a really simple way around this, but below is basically what I'm trying to accomplish:

foreach($POST['myPost'] as $myPost && $POST['c_id'] as $postID) { mycode; }

Thanks! 🙂

you can do a foreach inside a foreach ie

foreach ($array as $k=> $v){

foreach ($v as $foo){
echo $foo;
}
}

but im really not suer what you are exactly after.

You answer gives what I don't want - a double answer.

I'd like to have results from a form spit out. There's TWO arrays in the form, and each one needs it's own variable.

The only way I can think of is by doing a foreach with two statements in it, which is why I posted here, because I'm pretty sure there's gotta be a REAL way to do it that's actually pretty simple.

My output is going to be something like:

foreach($POST['one'] as $var1 && $POST['two'] as $var2) {
echo ' I like $var1 and $var2';
}

I hope that clears it up for what I'm trying to do.

how about showing some actual code, as your yet to make much sense.

What about using the key (or value) of the first to access the second?

i.e.

<?php
  $_POST['one'] = array(1,2,3,4);
  $_POST['two'] = array(4,3,2,1);
  foreach($_POST['one'] as $key => $value){
    echo $_POST['two'][$key]; // should print 4, then 3, etc...
  }

duckyB

BINGO.

You are awesome-o. 🙂

Thank you so much!!

For future references, here's how I tweaked that to work:

foreach($_POST['question'] as $key => $value){

$question = $_POST['question'][$key];
$answer   = $_POST['answer'][$key];

echo "Q: $question<br />A: $answer";
  }

Sweet. If you have no more questions, please mark this thread resolved.
