I want to be able to select multiple items from the siteTree, so i could say asssign a banner to multiple pages.

map() doesn't seem to work anyone know of another way.
[warning] array_keys() expects parameter 1 to be array object given
error line 138 ListboxField.php

line 138 = $hasCommas ....

i did try explode but that doesn't seem to solve

why does map(0 work with checkboxes but not listbox

Checkbox works

 

	      $SiteTreeIDs = SiteTree::get();
	  
	       if (!empty($SiteTreeIDs)) {   
	          $map = $SiteTreeIDs->map('ID', 'Title');
	          $fields->addFieldToTab('Root.Main',
	               new CheckboxSetField(
	                   $name = "selectedPagesFld",
	                    $title = "Select Pages",
	                  $source = $map
	            ));
	            }

ListboxField doesn't

 

 $SiteTreeIDs = SiteTree::get();
	         
 if (!empty($SiteTreeIDs)) {   
	          
	          $treemap = $SiteTreeIDs->map('ID', 'Title');
	          $mylistboxfield = new ListboxField(
                                             'selectedPagesFld',
                                             "Select Pages", 
                                             $source = $treemap,
	                                   $value = ""
	                                   );
	                  
	                 $mylistboxfield->setMultiple(true);    
	               
	                 $fields->addFieldToTab('Root.Main',$mylistboxfield);
	                    
	                    } 
	            
	            
	           /*  */

      return $fields;

I realise this post is a little old, however just stumbled across the same issue today and found the solution. You need to append the method "toArray()" onto the map function:


 $SiteTreeIDs = SiteTree::get();
	         
 if (!empty($SiteTreeIDs)) {   
	          
	          $treemap = $SiteTreeIDs->map('ID', 'Title')->toArray();
	          $mylistboxfield = new ListboxField(
                                             'selectedPagesFld',
                                             "Select Pages", 
                                             $source = $treemap,
	                                   $value = ""
	                                   );
	                  
	                 $mylistboxfield->setMultiple(true);    
	               
	                 $fields->addFieldToTab('Root.Main',$mylistboxfield);
	                    
	                    } 
	            
	            
	           /*  */

      return $fields;
