filter content / passing values from URL

Thursday 11 August 2005 4:43:39 am

hi,

I try to filter content (like the bugsystem) but it doesn't work.

I make an override template for a folder. The class has the attribute : branche ([Selektion] (id:279))with 3 options.

<div class="content-view-full">
	<h1>{$node.object.data_map.name.content|wash()}</h1>
	<form action={"content/action"|ezurl} method="post">
		<input type="hidden" name="DestinationURL" value="{$node.url_alias}" />
		<SELECT  name="(filter)" size="1">
			<OPTION value="service">Service</OPTION>
			<OPTION value="industry">Industry</OPTION>
			<OPTION value="healthcare">Healthcare</OPTION>
		</SELECT>
		<input type="submit" name="Submit" value="Go" />
	</form>

{section show=or($view_parameters.filter) }
	{let referencelist=fetch( 'content', 'list', hash( 'parent_node_id', 116,
							 'attribute_filter', array( 'and', array( 'branche', '=', $view_parameters.filter ) ) ) )} 
                {section var=filterlist loop=$referencelist sequence=array(bglight,bgdark)}
                    {node_view_gui view=line content_node=$filterlist}
                {/section}
	{$view_parameters.filter}
{/section}

{section-else}
	 {let page_limit=10
     list_items=array()
     list_count=0}
     {set list_items=fetch_alias( children, hash( parent_node_id, $node.node_id,
                                                 offset, $view_parameters.offset,
                                                 sort_by, $node.sort_array,
                                                 limit, $page_limit ) )}
     {set list_count=fetch_alias( children_count, hash( parent_node_id, $node.node_id ) )}
	
		<div class="content-view-children">
                {section var=child loop=$list_items sequence=array(bglight,bgdark)}
                    {node_view_gui view=line content_node=$child}
                {/section}
        </div>

            {include name=navigator
                     uri='design:navigator/google.tpl'
                     page_uri=$node.url_alias
                     item_count=$list_count
                     view_parameters=$view_parameters
                     item_limit=$page_limit}
            {/let}

{/section}

</div>

If no parameters given, the section-else display normal list.

If I select one from the form the URL looks ok.

Can someone help ?

There are some errors in your template.

The let tag for defining the variable referencelist should be closed.

There's a section-else for {section show=or($view_parameters.filter)}, but you've already closed this section.

Maybe this solves the problem.

Try with attribute ID instead of attribute identifier.

Also make sure your template code is correct. A good idea would be to test just a small piece of your code, the one that you think isn't working.

thx.

it must be a problem with selection attribute.

I have another attribute year (textline). Using this for testing my filter works.

{section show=or($view_parameters.filter) }
	{let referencelist=fetch( 'content', 'list', hash( 'parent_node_id', 116,
							 'attribute_filter', array( 'and', array( 'referenz/jahr', '=', $view_parameters.filter ) ) ) )} 
                {section var=filterlist loop=$referencelist sequence=array(bglight,bgdark)}
                    {node_view_gui view=line content_node=$filterlist}
                {/section}
		{$view_parameters.filter}
	{/let}
{section-else}
......

To make the list more dynamic, you could get the class attribute and loop over the options:

{def $classAttributes=fetch( 'class', 'attribute_list', hash( 'class_id', $class_id ) )}
    {foreach $classAttributes as $classAttribute}
        {if $classAttribute.identifier|eq('branche')}
            {def $options=$classAttribute.content.options}
                {foreach $options as $option}
                    <option value="{$option.id}">{$option.name|wash( xhtml )}</option>
                {/foreach}
            {undef $options}
        {/if}
    {/foreach}
{undef $classAttributes}

Replace $class_id with the id of your content class.

You'll have to fetch a list of class attributes because there's no function to fetch a specific class attribute.

big thx Kristof.

Dynamic list in the form and filter is working.

Here is the complete template :

<div class="content-view-full">
	<h1>{$node.object.data_map.name.content|wash()}</h1>
	<form action={"content/action"|ezurl} method="post">
		<input type="hidden" name="DestinationURL" value="{$node.url_alias}" />
		<SELECT  name="(filter)" size="1">
		{def $classAttribute=fetch( 'content', 'class_attribute', hash( 'attribute_id', 279 ) )}
    		{def $options=$classAttribute.content.options}
        		{foreach $options as $option}
            		<option value="{$option.id}">{$option.name|wash( xhtml )}</option>
        		{/foreach}
    	{undef $options}
		{undef $classAttribute}
		</SELECT>
		<input type="submit" name="Submit" value="Go" />
	</form>


	{section show=or($view_parameters.filter) }
		{let referencelist=fetch( 'content', 'list', hash( 'parent_node_id', 116,
								 'attribute_filter', array( 'and', array( 'referenz/branche', '=', $view_parameters.filter ) ) ) )} 
	                {section var=filterlist loop=$referencelist sequence=array(bglight,bgdark)}
	                    {node_view_gui view=line content_node=$filterlist}
	                {/section}
