How to pass a String variable from PHP to Javascript -

-

this question has answer here:

i'm trying pass string variable php javascript , giving me troubles.

i pas number variable per code below , works, once introduce (or uncomment) line var cityname = <?=$city;?>; in javascript code doesn't work. believe has type of data because if introduce number scity = 3 in php works.

thank you

i have following php:

<?php     $get_total_rows = 0;     $city = "london";      $db = pg_connect("$db_host $db_name $db_username $db_password");     $query = "select * table";     $results = pg_query($query);      $get_total_rows = pg_numrows($results);  ?>

and have following javascript:

<script type="text/javascript"> $(document).ready(function() { var track_load = 0; //total loaded record group(s) //var cityname = <?=$city;?>; var total_rows = <?=$get_total_rows;?>;  $('#results').load("autoload_process.php", {'rows':total_rows}, function() {track_load++;}); //load first group

in case of strings, content must between quotes (ex.: val = "content"). try this:

var track_load = 0; //total loaded record group(s) var cityname = "<?php echo $city; ?>"; // string var total_rows = <?php echo $get_total_rows;?>; // number
