Question

I have a map on my site that has plots placed on it using data from my table. The plots are placed with javascript as so…

addPostCode('<?php echo $array[$UID][0]; ?>');
addPostCode('<?php echo $array[$UID][1]; ?>');
addPostCode('<?php echo $array[$UID][2]; ?>');

Somehow I need to see if the variable exists in my table, and then if so, generate an additional line and increment my array number, so based on the above 3 records, the next line would be…

addPostCode('<?php echo $array[$UID][4]; ?>');

Can I ask if this is possible?

Answer 1

You just need to loop through all of the members of the $array[$UID] variable.

<?php
    foreach($array[$UID] as $thing) {
        $encodedThing = json_encode($thing);
        echo "addPostCode($encodedThing);\n"
    }
?>

I used json_encode() because it does whatever escaping is necessary to make your data JavaScript-compatible.
