as you can see it is an array within an array type situation, I am trying to loop through it to pull out the first_name + surname of each entry, however I get the following error when I try to do it,
A PHP Error was encountered
Severity: Notice
Message: Undefined index: firstname
Filename: admin/candidate_list.php
Line Number: 5
I looping through it like this at the moment,
<?php foreach ($candidates as $k => $v) : ?>
<li><?php echo $v[0]['first_name']. " ".$v[0]['surname']; ?></li>
What am i doing wrong?

Answer 1

What does this give you?
<?php foreach ($candidates as $k => $v) print_r($v); ?>
I don't know how $v['id'] would be defined either given that array, so there's something else you're leaving out...
And you're using site_url()... Do I smell CodeIgniter? ;)

Answer 2

Your array is too deep for that loop. I am assuming that $candidates is the name of the whole big array? You don't need each candidate in their own array, try getting your results in an array that has one less level and that foreach will work.

Answer 3

<?
for($i=0; $i=50; $i++){
foreach ($candidates[$i] as $v){
?>
<li><?php echo $v[0]['first_name']. " ".$v[0]['surname']; ?></li>
<?
}
}
?>
