Select from and array_combine

Hi guys...
I'm trying to combine the results of two arrays:

<?php
// first array
$points = array(100, 90, 80);
// second array
$db =& JFactory::getDBO();
$query = "
SELECT `cf_id`, 
FROM `#__chronoforms_my_table`
WHERE `check2` != '' AND `radio0` = 'M' AND `cat_cerchi` = 'D' AND `rifiuto_cerchi` = ''AND `edizione_anno` = '$anno_impostato'
ORDER BY somma_pts_cerchi DESC, date_int ASC
LIMIT 10
";
$db->setQuery($query);
$result = $db->loadObjectlist();
// combine the arrays
$result_2 = array_combine ($result, $points);

foreach($result_2 as $k=>$v){ echo $k.' -> '.$v.'<br />'; }
?>

But it doesn't work.
I'd like it to show me something like this:
first cf_id -> 100
second cf_id -> 90
third cf_id -> 80
etc...
Could you help me understand what's wrong?

Sorry for bothering you again but maybe I've been able of doing something better than before...
Using this code it associates cf_ids and points:

<?php

$db =& JFactory::getDBO();

$query = "
    SELECT `anno_edizione`
        FROM `#__chronoforms_scelta_edizione`;
            
";
$db->setQuery($query);
$anno_impostato = $db->loadResult();

$punti = array(100, 90, 80);


$db =& JFactory::getDBO();
$query = "
SELECT `cf_id`
FROM `#__chronoforms_iscrizioni_olimpiadi`
WHERE `check2` != '' AND `radio0` = 'M' AND `cat_cerchi` = 'D' AND `rifiuto_cerchi` = ''AND `edizione_anno` = '$anno_impostato'
ORDER BY somma_pts_cerchi DESC, date_int ASC
LIMIT 3
";
$db->setQuery($query);
$cf_ids = $db->loadResultArray();

$prova = array_combine ($cf_ids, $punti);


foreach($prova as $k=>$v) { echo "

<input type='text' name='cf_id' id='cf_id' value='$k' />  
<input type='text' name='class_gen_cerchi' id='somma_pts_cerchi' value='$v' /> <br/>"; }

?>

<div class="form_item">
  <div class="form_element cf_button">
    <input value="Conferma" name="button_0" type="submit" />
  </div>
  <div class="cfclear"> </div>
</div>

Now I don't know why when i submit the form it updates only the first record of my table. The others aren't updated except the cf_user_id (the only field i don't want to be updated)... I've been googlin' a lot but i didn't find an answer helping me to solve this problem...

Hoping that someone could help me... Thanks in advance...

Hi federico85,

I think that $result = $db->loadObjectlist(); will give you an array of objects. You can't then expect this to combine with a standard array and give you a meaningful result. Have you output $result to see exactly what you have there?

If you use $result = $db->loadResultArray(); then you should get a better result.

Hi Bob!
Thanks for your reply...
As you can see, in the second answer I posted, I used loadResultArray(); and using this it shows me the result i wanted to get.

Eg. cf_id -> points

Now when i try to submit the form it updates only the first record of my table. The others aren't updated except the cf_user_id (the only field i don't want to be updated)...

What can i do for updating other records avoiding the cf_user_id to be updated?

Another question:

The results i have to combine are points ( eg: 100, 90, 80, 70, 60, 50, 40, 30, 20, 10) and the first 10 position of a ranking (cf_ids).
I read that array_combine can be used only if the number of results extracted from the 2 arrays you want to combine are equal eg: 10 cf_id and 10 points. But you can't use it if you want to combine 8 cf_id and 10 points. How can i use array_combine without being sure if the number of results i could get from the cf_ids array is bigger than ten?

Thanks in advance...
