my stepping through an array using "next()" is not working.

[silverglade]

Hi, I'm trying to step through this array when the "further " button is pressed and it should change the image in the div when I echo it out.

 

I'm getting the following error

 

Fatal error: Only variables can be passed by reference in C:\wamp\www\SUN_DRAGON_GAME\gamestart.php on line 224

 

here is the array

 

$currentLocation = array
( 
'teardrop_ocean_bg' => array
(
'level_1'=>"<img src='<img src='sundragon_environments/ocean/ocean1_FRAME.jpg'/>'",
'level_2'=>"<img src='<img src='sundragon_environments/ocean/ocean1_FRAME2.jpg'/>'",
'level_3'=>"<img src='<img src='sundragon_environments/ocean/ocean1_FRAME3.jpg'/>'",
'level_4'=>"<img src='<img src='sundragon_environments/ocean/ocean1_FRAME.jpg'/>'",
'level_5'=>"<img src='<img src='sundragon_environments/ocean/ocean1_FRAME.jpg'/>'"
)
);

 

and here is the code I'm using to try to step through the "teardrop_ocean" array.

 

$currentLocation='teardrop_ocean';//declare variables/this is set after we click on image map link for teardrop
$currentLocArray='';
//the following is set after we click on the teardrop ocean link on the image map .

//check if the current location is teardrop ocean, if so, set current loc array to the teardrop ocean bg array.
if($currentLocation=='teardrop_ocean'&& !empty($_POST['further']))
{
$currentLocArray=$currentLocation['teardrop_ocean_bg'];
}

//if in teardrop, and further is pressed, go to next element, which is a new img src background.
if($currentLocArray==$currentLocation['teardrop_ocean_bg']&& !empty($_POST['further']))
{
next($currentLocation['teardrop_ocean_bg']);
}

 

any help greatly appreciated. Thanks. Derek

I changed the code. This just shows up a black div. Not the image.

 

$currentLocation='teardrop_ocean';//declare variables/this is set after we click on image map link for teardrop
$currentLocArray='';
//the following is set after we click on the teardrop ocean link on the image map .

//check if the current location is teardrop ocean, if so, set current loc array to the teardrop ocean bg array.
if($currentLocation=='teardrop_ocean'&& !empty($_POST['further']))
{
 $echoLocation=next($teardrop_ocean_bg);
}

 

I output $echoLocation later on inside the div.

What's the deal with this?:

 

<img src='<img src='sundragon_environments/ocean/ocean1_FRAME.jpg'/>

 

You have <img src='<img src=' which is going to cause problems almost immediately.

 

Should it not just be:

"<img src='sundragon_environments/ocean/ocean1_FRAME.jpg'/>"

?

 

Also, another tidbit of information: In HTML the <img> tag has no end tag, but in XHTML the <img> tag must have a closing tag.

 

Let us know if that fixes the problem!

awesome thanks very much! wow I can't believe I made that mistake. Also, when I run it now it only goes to background 2. and doesn't show background 1. Any more help greatly appreciated. Thanks for pointing that out. Derek
