Template Problem

[ckgreenman]

Hello, I'm attempting to port a mod (someone else's) to VB4 and I'm having a problem with one of the templates.


The mod has a main templates and calls the other templates using variables. I modified the main template and the php file so that the variables are now registered and the sub templates are called using the {vb:raw } syntax. The problem is in one of the sub templates I need to pass variables to it as well but as soon as I try to specify a {vb: } type variable (even stylevars) it won't let me save the template. I get the following error:

Warning: Invalid argument supplied for foreach() in [path]/includes/functions.php on line 3332

and the following dialog:



Any any ideas where the problem might be?

Thanks.


EDIT: I checked and as far as I'm aware of there are no if statements in the template.

What is the code you are adding that seems to be causing the problem?

What triggers it is {vb: anything. I did a test adding {} then {vb} then {vb:} and the last one triggered it.

I found a work around though. There was some javascript in the template so I pulled all of it out and put it into a new template then called IT from the main template and now I can save the original template without error.

EDIT:
The problem is definitely in the javascript somewhere. The javascript is needing variables from the PHP file but when I try to reference the variable using {vb:raw variablename} i get the same error when I save the template.

I poked through the javascript and everything LOOKS ok but I'm no expert. Is there anything I should keep an eye out for?

I had a similar error pop up not so long ago. Check that the "<vb:if condition>" tags are all written correctly, since that's what caused the same error when I was porting templates and had missed one.

In vB3 it's: <if condition="...."><else /></if>
In vB4 it's: <vb:if condition="...."><vb:else /></vb:if>

I'm not using HTML <if> statements though. The template in question consists entirely of javascript (with the addition of the <script></script> tags). How would that apply?

You might wanna post the template here then (or the offending part) otherwise we can't help much.

Ok this is enough to generate the issue

	  <script type="text/javascript">
	  //<![CDATA[
	  window.onload=Load_Map

	  function get_icon(type) {
		var color;
		if ((typeof(type)=="undefined") || (type==null)) 
		{ 
		color = "red" 
		} 
		else { 
		color = type 
		}
		var icon = new GIcon();

		icon.image = "$bburl/images/googlemapme/mm_20_"+ color +".png"; 
	

		icon.shadow = "$bburl/images/googlemapme/mm_20_shadow.png";
		icon.iconSize = new GSize(12, 20);
		icon.shadowSize = new GSize(22, 20);
		icon.iconAnchor = new GLatLng(20, 2);
		icon.infoWindowAnchor = new GLatLng(1, 5);
		return icon;
	
	  }
	  
		 	  //]] </script>

As written it saves fine but if I add a vb variable (for example {vb:raw map_type}) then it won't save.

put <vb:literal> and </vb:literal> around your javascript.

Lynne, That seems to have fixed it. Thanks a bunch.
