1dxb Posted June 15, 2015 Share Posted June 15, 2015 I am very new to php. I have a simple website that loops through a mysql database and draws polygons for every row. It also assigns a custom attribute (name) to every polygon that the user can see when he clicks the polygon. When a user clicks the polygon, he should see the value of variable "bname". The code works perfectly when I assign bname to a coordinate from the DB: var bname = ('.$row[coord1].'); The code fails when I assign bname to another column that is a string: var bname = ('.$row[name].'); All data in the database is text format, I suspect that maybe I am using the wrong syntax to return a string value from the database? I need to assign bname to the name column in the database.. This is the full code: $findmap= 'SELECT * FROM build2'; if(!$result = $con->query($findmap)){ die('There was an error running the query [' . $con->error . ']'); } else { while ($row = $result->fetch_assoc()) { echo ' var polypath = [new google.maps.LatLng('.$row[coord1].'), new google.maps.LatLng('.$row[coord2].'), new google.maps.LatLng('.$row[coord3].'), new google.maps.LatLng('.$row[coord4].'), new google.maps.LatLng('.$row[coord5].'), new google.maps.LatLng('.$row[coord6].'), new google.maps.LatLng('.$row[coord1].') ]; var bname = ('.$row[name].'); var dxbmap = new google.maps.Polygon({ custom: bname, path:polypath, strokeColor:"#0000FF", strokeOpacity:0.8, strokeWeight:1, fillColor:"#0000FF", fillOpacity:0.1 }); dxbmap.setMap(map); google.maps.event.addListener(dxbmap, "click", function() { alert(this.custom); }); '; } } ?> Quote Link to comment https://forums.phpfreaks.com/topic/296834-php-variable-declaration-error-mysql/ Share on other sites More sharing options...
Solution Ch0cu3r Posted June 15, 2015 Solution Share Posted June 15, 2015 If $row[name'] contains a string then the value for the bname javascript variables needs to be wrapped in quotes not parenthesises var bname = \''.$row['name'].\''; // or var bname = "'.$row['name'].'"; Quote Link to comment https://forums.phpfreaks.com/topic/296834-php-variable-declaration-error-mysql/#findComment-1513977 Share on other sites More sharing options...
