Pushing to javascript array in php loop

**sirsaula** · 07-20-2012 02:51 PM

I am trying to push to the javascript array after looping 200 times through the member array to push every member that matches the department selected description into the javascript array., However it fails

PHP Code:


<? $i = 0 ;

    while( $i < 200)

    {

    if ($members[$i]['department'] == $depttts){

    

    echo "<script type='text/javascript'>contacts.push({"NAME":"SirSaula","TITLE":"John","CONTACT":"bab","RESEARCH":"Ph.D."});</script>";

    }

    else {

    $i++;

    }

    }

    ?>

The way you have it written it would loop forever.

try this:

PHP Code:


<!DOCTYPE html>

<head>

    <script>

        contacts = [];

    </script>

</head>





<? $i = 0 ; 

    while( $i < 200) 

    { 

         

            echo "<script type='text/javascript'>contacts.push({\"NAME\":\"SirSaula\",\"TITLE\":\"John\",\"CONTACT\":\"bab\",\"RESEARCH\":\"Ph.D.\"});</script>"; 

            $i++; 

         

    } 

    ?>



<script>

    

    alert(contacts);

</script>

If I understand correctly, I'd probably use a foreach() loop:

PHP Code:


<script type='text/javascript'>
<?php
foreach($members as $memb)
{
    if ($memb['department'] == $depttts){
        echo 'contacts.push({"NAME":"SirSaula","TITLE":"John","CONTACT":"bab","RESEARCH":"Ph.D."});';
        // possible a "break;" here if you want to terminate loop once a match is found?
    }
}
?>
</script>

Your method worked now the final thing instead of strings i wish to push the entire php array contents into the javascript array

My attempt is below but it did not work.

PHP Code:


<?php
foreach($members as $memb)
{
    if ($memb['department'] == $depttts){
        echo 'contacts.push({"NAME":<?php echo json_encode($memb[i]['firstname']); ?>,"TITLE":<?php echo json_encode($memb[i]['title']); ?>,"CONTACT":<?php echo json_encode($memb[i]['email']); ?>,"RESEARCH":"Ph.D."});';
        // possible a "break;" here if you want to terminate loop once a match is found?
    }
}
?>

I'd let PHP do some of the work JSON-wise:

PHP Code:


<?php
// test data:
$members = array(
    array(
        'department' => 'good',
        'firstname'  => 'John',
        'title'      => 'Mr.',
        'email'      => 'foo@bar.com'
    ),
    array(
        'department' => 'bad',
        'firstname'  => 'Jack',
        'title'      => 'Dr.',
        'email'      => 'bar@foo.com'
    ),
    array(
        'department' => 'good',
        'firstname'  => 'Jane',
        'title'      => 'Ms.',
        'email'      => 'foo@bar.net'
    )
);
$depttts = 'good';
?>
<script type='text/javascript'>
<?php
foreach($members as $memb)
{
    if ($memb['department'] == $depttts){
        $data = array(
            "NAME" => $memb['firstname'],
            "TITLE" => $memb['title'],
            "CONTACT" => $memb['email'],
            "RESEARCH" => "Ph.D."
        );
        $json = json_encode($data);
        echo "contacts.push($json);\n";
    }
}
?>
</script>

Output:

Code:

<script type='text/javascript'>
contacts.push({"NAME":"John","TITLE":"Mr.","CONTACT":"foo@bar.com","RESEARCH":"Ph.D."});
contacts.push({"NAME":"Jane","TITLE":"Ms.","CONTACT":"foo@bar.net","RESEARCH":"Ph.D."});
</script>
