Pushing to javascript array in php loop

sirsaula

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

[code=php]<? $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++;
}
}
?>

[/code]

The way you have it written it would loop forever.

try this:

<!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:

<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
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
// 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:

<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>
