Question

First I want to thank you guys here, because your posts have gotten me as close as I have been in the past week or so to resolve this; but I need help to finish this. I will admit, this process is still not clear in my mind and I am also exhausted to please bear with me

The script below has gotten me so close
What I need to accomplish: I need to grab some data from my db, stick it into an array and then access/use the
values in that array in my external javascript file. I’ll be using on the onload event.

<s c r i pt language="javascript1.2">
var arr = new array(<?php 
$result = mysql_query("select account_id, display_name, id from field where account_id = $holdAcctID and required_flag = 1");
$count = mysql_num_rows($result);
if($count>0){
  for( $i=0;$i<$count-1;$i++) {
    $row = mysql_fetch_row($result);
    echo $row[2],',';
  }
  $row = mysql_fetch_row($result);
  echo $row[2],',';
}
?>);
</s c r ipt>

above script produces this in my view source page:

<s c ript language="javascript1.2">
**var arr = new array(2860,2861,2862,2863,2864,3293,3294,3296,3521,3523,);**
</s c ript>

Q1 – how can i update the above array, so it holds the data from the same like the example below:
as you can see, it currently only holds, displays the id value

myReqField[0]
    [account_id] => 72
            [display_name] => Client Contact Name
            [id] => 2860
myReqField[1]
    [account_id] => 72
            [display_name] => Contact Phone
            [id] => 2888
myReqField[2]
        [account_id] => 72
            [display_name] => Email Address
            [id] => 2865
myReqField[3]
    [account_id] => 72
            [display_name] => Approval needed
            [id] => 2841

Q2 – how easy would it be to do this and place the results into a comma separate list. If fairly easy how would I code that and how can I access the list/value from my external javascript

Q3 – If Q2 is not possible/easy to set up, how then do I pull the array in to javascript file. Several have mentioned json, but the other developer doesn’t want to use it.

Thank you in advance!

Answer 1

I know you said the other developer doesn’t want to use JSON but that’s exactly what you’re looking for. Is there a particular reason (s)he’s opposed to using it?

<?php
    $data = array();
    $results = mysql_query('...');
    while($result = mysql_fetch_assoc($results)) {
        $data[] = $result;
    }
?>
<script language="javascript1.2">
    var arr = <?php echo json_encode($data); ?>;
</script>
