Have label permanently appear on Google Map

Hi all.

I have the code below that displays markers for the addresses in my MySQL table. Currently when you click a marker it will display the name, address, city , state, zip code and type.

I would like for it to show just the name in a label when the map is displayed and if the user clicks a marker then it will display the detail information I listed above (i.e. name, address, city etc.)

How can I do this?

Ok. I tried using the MarkerWithLabel in my code below, but it doesn't show the labels and it does not show the markers. When I comment out the MarkerWithLabel and use Marker instead then I see the markers and obviously no labels.

What am I doing wrong with the code?

could you post what you get from GetBuilderCommunityMapAddresses.php ?

Sure, below is what I get, but I changed the addresses as that is sensitive information.

<markers>
<marker name="Builder A" address="123 SW 143RD WAY" city="MyCity" state="MA" zipcode="00023" lat="30" lng="-80" type="Builder"/>
<marker name="Builder B" address="333 SW 33 ST" city="YourCity" state="NY" zipcode="12222" lat="40" lng="-80" type="Builder"/>
<marker name="MMA" address="5555 N 44 ST" city="OurCity" state="TX" zipcode="56677" lat="22" lng="-80" type="Community"/>
<marker name="aa" address="789 W 43 Ct" city="City A" state="CA" zipcode="55666" lat="23" lng="-80" type="Community"/>
<marker name="MM" address="44444 W 3rd ave" city="Lala" state="OR" zipcode="45667" lat="67" lng="-80" type="Community"/>
</markers>

Nevermind, got it to work.

I had to change the line to: var marker = new MarkerWithLabel

Instead of var marker = new new google.maps.MarkerWithLabel

And I had to fix labelContent I had originally typed it as labelContect.

Thanks again for all your help!
