Assets custom field for Taxonomy

gistfile1.txt

This will add an 'Assets' fieldtype to Taxonomy. 

Caveats: 
* only images will be visible in the Assets sheets
* only one image can be selected
* shows all file upload locations that the user's member group can access
* stores the actual image url NOT the Assets path eg {filedir_1}my_image.jpg. 
Iain - you might want to implement Assets path {filedir} parsing for your Taxonomy module 
tags and then store the Assets url instead (which is in files[0].path). Then users can move 
the image in Assets and it won't break the link...

mcp.taxonomy.php

1. Add this just below the opening class Taxonomy_mcp {
private static $_assets_init = FALSE;

2. Add this add around line 598, below unset($entries_select_dropdown)...

// Assets field
foreach($vars['tree_settings']['fields'] as $custom_field)
{	
	if ($custom_field['type'] == 'assets')
	{
		// Make sure that Assets is installed and include dependencies
		if (array_key_exists('assets', $this->EE->addons->get_installed()))
		{	
			if ( ! self::$_assets_init)
			{
		    		require_once PATH_THIRD.'assets/helper.php';
		    		$assets_helper = new Assets_helper;
		    		$assets_helper->include_sheet_resources();
				self::$_assets_init = true;
			}
		
			$assets_js = '
			
			$input 	 = $(\'input[name="custom_fields['.$custom_field["name"].']"]\');
			$preview = $input.next("a").next(".preview");
			$delete  = $preview.find(".delete-preview");
			$delete.css("display", "block");
			
			var sheet'.$custom_field["order"].' = new Assets.Sheet({

			    // optional settings (these are the default values):
			    multiSelect: false,
			    filedirs:    "all", // or array of filedir IDs
			    kinds:       ["image"], // string "any", or array of file kinds e.g. ["image", "flash"]

			    // onSelect callback (required):
			    onSelect: function(files) {
			        // files is an array of file paths and URLs, e.g.:
			        // [
			        //   { path: "{filedir_1}filename1.jpg", url: "/images/uploads/filename1.jpg" }
			        //   { path: "{filedir_1}filename2.jpg", url: "/images/uploads/filename2.jpg" }
			        // ]
			
					$input.attr("value", files[0].url);
					
					$preview.find("img").attr("src", files[0].url);
					$preview.css("display", "block");
					
			    }
			});
			$input.next("a").click(function(){
				sheet'.$custom_field["order"].'.show();
				return false;
			});
			
			$delete.click(function(e) {
				$preview.css("display", "none");
				$input.attr("value", "");
				return false;
			});
			';
			$this->EE->cp->add_to_foot('<script type="text/javascript">'.$assets_js.'</script>');
		}
	}

3. Add this at around line 139 inside the switch/case block...

case($custom_field['type'] == 'assets'):
	if ( ! empty($value))
	{
		$thumb_html = '<div class="preview">';
	}
	else
	{
		$thumb_html = '<div class="preview" style="display: none;">';
	}
	
	$thumb_html .= '<img src="'.$value.'" alt="" style="width: 160px; border: 5px solid white; margin-top: 10px;">';
	$thumb_html .= '<a href="#" class="delete-preview">delete</a>';
	$thumb_html .= '</div>';
	$this->table->add_row(
		$custom_field['label'].':',
		form_input('custom_fields['.$custom_field['name'].']', $value, 'id='.$custom_field['name'].',  style="width: 60%;"')
		.'&nbsp;&nbsp;<a href="#" class="submit">select</a>'
		.$thumb_html
	);
	break;
