Having trouble with selected option

[neoh]

Can someone tell me how to get my selected option to reflect what option is selected after a page update. I checked PHP and register_globals are on. Do I have the code right?

<select name=\"centerPoint\" class=\"selectBoxes\">
<option";
if($centerPoint=="41.409775, -80.744018), 7") echo " SELECTED";
echo " value=\"41.409775, -80.744018), 7\">The Entire Area</option>
<option";
if($centerPoint=="41.849616, -79.143447), 11") echo " SELECTED";
echo " value=\"41.849616, -79.143447), 11\">Allegheny River - Kinzua Dam to Buckaloons Rec Area</option>

//get the first result if a category was selected
if(isset($_REQUEST['centerPoint']))
$centerPoint=$_REQUEST['centerPoint'];
//if no category was selected, these results won't exist, so define default values
if(!isset($centerPoint) or strlen($centerPoint)<1) $centerPoint="41.409775, -80.744018), 7";

// CREATE THE MAP
var map = new GMap2(document.getElementById(\"map\"));
map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());

// Set the center point of your map and set the zoom

map.setCenter(new GLatLng($centerPoint);

Welcome to WebmasterWorld neoh,

I assume this is after the user submits your form. Is it being sent by POST or GET?

also, is it not selecting the proper value? (I assume so or you wouldn't be posting ;))

have you viewed the source of the final page to see if it is possibly just an error in the html?

[neoh]

After a post:
<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">

It shows the first option in the list no matter what.

And I didnt see any error in the html

Try changing the values of the select to something a little more basic (like 1 and 2) for testing purposes. I'm not sure if I like those )'s in the value - that could be affecting it.

[neoh]

Is there another way of rewriting the code so it will work the same?

[eelixduppy]

Welcome noeh!

Here's a related thread [webmasterworld.com].

Note the use of the ternary operator [us3.php.net].

good luck!

[neoh]

Would this line

<option";
if($centerPoint=="41.409775, -80.744018), 7") echo " SELECTED";
echo " value=\"41.409775, -80.744018), 7\">The Entire Area</option>

be changed to this?

<option";
if($_POST['centerPoint'] == "41.409775, -80.744018), 7") echo " SELECTED";
echo " value=\"41.409775, -80.744018), 7\">The Entire Area</option>

[eelixduppy]

<option value="41.409775, -80.744018, 7"
<?php 
echo ($_POST['centerPoint'] == "41.409775, -80.744018, 7")? " SELECTED":"";
?>
>The Entire Area</option>

Your logic would work also, just you have some syntax errors. The above is just a more condensed version using the ternary operator.

Also try to see what exactly is in the $_POST variable:

print_r($_POST);
die();

just for testing reasons, certainly

I need to have the ) as part of the data. Will this effect it?

Example:

"41.409775, -80.744018), 7"

[eelixduppy]

No it's fine, I just thought it to be a spelling error ;)

[neoh]

Works now. Thank you very much. You guys are great. :)

[neoh]

I have one more problem. I select the 2nd option and my 3rd option and it works but when I go back to my first option it doesn't work. Does it have to do with these lines of code?

//get the first result if a category was selected
if(isset($_REQUEST['centerPoint'])) 
$centerPoint=$_REQUEST['centerPoint'];
//if no category was selected, these results won't exist, so define default values 
if(!isset($centerPoint) or strlen($centerPoint)<1) $centerPoint="41.409775, -80.744018), 7";

[eelixduppy]

Try something like this:

if(![url=http://us2.php.net/manual/en/function.empty.php]empty[/url]($_POST['centerPoint'])) {
$centerPoint = $_POST['centerPoint'];
} else {
$centerPoint = "41.409775, -80.744018), 7";
}

I tried it and its still not working right. The first result is shown when I first open the page. I select the next 2 options and they work then wnt I go back to the first option it doesn't work. This is for a google map by the way. Can someone check my link to see what it is doing?

[neoh]

The first time the page is open nothing is selected (see source code)

<select name="centerPoint" class="selectBoxes">
<option name="centerPoint" value="41.409775, -80.744018,) 7">The Entire Area</option>
<option name="centerPoint" value="41.849616, -79.143447), 11">Allegheny River - Kinzua Dam to Buckaloons Rec Area</option>
<option name="centerPoint" value="41.403941, -81.171562), 12">Cuyahoga River - Russell Park</option>
</select>

I am able to select the second and third options and the will show selected but if I select the first option it never shows selected. Any ideas why?

[outdoorxtreme1]

Should I make a option with value like "Select an Area" or is there a way around this?

[outdoorxtreme1]

Nevermind I just figued it out. I was an overlooked mistake on my part. Thanks for the help everyone.

[eelixduppy]

if($outdoorxtreme1 == $neoh) {
echo 'Glad you got it working!';
} else {
echo 'What?';
}
