Low List for ExpressionEngine

Low List lets you loop and search through a list of character-separated items. Requires EE 3.0.0+ and is especially useful in combination with Low Search. The EE2 compatible version is available here.

Installation

• Download and unzip;
• Copy the low_list folder to your system/user/addons directory;
• In your Control Panel, go to the Add-on Manager and install Low List;
• All set!

Tags

Each tag

Use the Each tag to loop through a list to character-separated items.

Parameters

• items=: the items you want to loop through, separated by the character given in the sep parameter. Use a colon : to separate keys and values.
• as=: variables to use in the template. Defaults to key:val.
• sep=: character that separates each item. Defaults to |.
• range=: set to yes to treat the items as the start and end values of a range.

Examples

{exp:low_list:each items="north|east|south|west" as="direction"}
    You can go {direction}.
{/exp:low_list:each}

Using key/value pairs and custom variable names:

{exp:low_list:each items="asc:Ascending|desc:Descending" as="value:label"}
	<label>
	    <input type="radio" name="sort" value="{value}">
	    {label}
	</label>
{exp:low_list:each}

Using key/value pairs and a custom separator:

<select name="orderby_sort">
	{exp:low_list:each items=":Relevance;date|asc:Publish date;title|asc:Title" sep=";"}
		<option value="{key}">{val}</option>
	{/exp:low_list:each}
</select>

Using the items parameter to define a numerical range:

{exp:low_list:each items="99|0" range="yes"}
	{val} bottle{if val != 1}s{/if} of beer on the wall.
{/exp:low_list:each}

Has tag

Use the Has tag to see if a given value is present in a given character-separated list. When the value is present, the tagdata is returned. Otherwise, an empty string is returned.

Parameters

• value=: the value to search for (needle).
• items=: the items you want to search through, separated by the character given in the sep parameter (haystack).
• sep=: character that separates each item. Defaults to |.

Examples

{exp:low_list:has value="spork" items="knife|fork|spoon"}
    We have a spork!
{/exp:low_list:has}

Setting a checked or selected attribute:

{exp:channel:categories style="linear"}
	<option value="{category_id}"{exp:low_list:has value="{category_id}" items="1|2|3"} selected{/exp:low_list:has}>
		{category_name}
	</option>
{/exp:channel:categories}

Has Not tag

Use the Has Not tag to see if a given value is not present in a given charachter-separated list. Works identically to the Has tag:

{exp:low_list:has_not value="spork" items="knife|fork|spoon"}
    We don't have a spork!
{/exp:low_list:has_not}
