Template tags

In most cases, the simple global variable syntax, eg. {my_var} will do. Global variables do not support parameters, nor do they support the variable pair syntax. However, tags do.

Parse tag

{exp:low_variables:parse var="my_var"}

Use the Parse, Single or Pair tag to parse variables during the Module & Plugin stage (read more about the parsing stages). You can also use parameters, which will allow for more options than just using the variable syntax. Some variable types, like RTE and Grid, require using the tag syntax to trigger additional processing.

Note: Whenever you need parameters or additional processing, use the tag syntax rather than the variable syntax.

Parameters for the low_variables:parse tag
Parameter Description
var Name of the variable you want to parse. Use a colon to separate site name and variable name if you want to parse a variable belonging to a specific site, eg. my_site:my_var. If this parameter is omitted, all Low Variables inside the tag pair are simply replaced with their values.
multiple If set to yes, the tag will loop through the different values of the variable. This parameter applies to any of the native variable types that use the separator setting: Checkbox Group, Radio Group and all Select types. Use only in combination with the var parameter. Not needed in EE3.
limit Use in combination with multiple="yes" to limit the number of results displayed.
3rd party If you’re displaying a 3rd party field type, you can use all parameters you would normally use for the field channel variable pair.
Variables for the low_variables:parse tag pair
Variable Description
{my_var:data} The variable value.
{my_var:data_label} The variable value’s label, when displaying a Checkbox Group, Radio Group or Select variable type.
{my_var:label} The variable label, as displayed in the Control Panel.
{my_var:count} Current count of the loop.
{my_var:total_results} Total of iterations of the loop.
3rd party If you’re displaying a 3rd party field type, you can use all variables you would normally use inside the field channel variable pair.

Note: the {my_var:…} variables are only available when using the Parse tag pair or Pair tag pair, and if the variable type allows multiple items to be selected. For more options on the native variable types, check their properties.

  and {my_other_var}.

  <p>
    Number {my_select_var:count} of {my_select_var:total_results}:
    {my_select_var:data} ({my_select_var:data_label})

Single tag

{exp:low_variables:single var="my_var"}

In order to avoid conflicts with multiple instances of the Parse tag, both single and paired, you can use the alias {exp:low_variables:single} for single tag use. It is identical to the Parse tag, but meant for single tag use only.

Pair tag

{exp:low_variables:pair var="my_var"}{/exp:low_variables:pair}

In order to avoid conflicts with multiple instances of the Parse tag, both single and paired, you can use the alias {exp:low_variables:pair} for tag pair use. It is identical to the Parse tag, but meant for tag pair use only.

Label tag

{exp:low_variables:label var="my_var"}

You can display the label of any variable by using this tag. Use as single tag only.

Parameters for the low_variables:label tag
Parameter Description
var Name of the variable you want to fetch the label from. Use a colon to separate site name and variable name if you want to parse a variable belonging to a specific site, eg. my_site:my_var. This is a required parameter.

Options tag

This tag pair allows you to display the options for a given variable. Use this in combination with the Checkbox Group, Radio Group and Select variable types.

Parameters for the low_variables:options tag
Parameter Description
var Name of the variable you want to parse. Use a colon to separate site name and variable name if you want to parse a variable belonging to a specific site, eg. my_site:my_var. This is a required parameter.
Variables for the low_variables:options tag
Variable Description
{my_var:data} Value of the option.
{my_var:data_label} Associated label of the value.
{my_var:label} Label of the variable itself.
{active} Set to y if the variable data contains the current option.
{checked} Returns  checked="checked" if current option is active.
{selected} Returns  selected="selected" if current option is active.
{total_results} The total amount of options.
{count} The count out of the current option.
{exp:low_variables:options var="my_multi_var"}
  {if count == 1}<ul>{/if}
    <li{if active == "y"} class="active"{/if}>{my_multi_var:data_label}</li>
  {if count == total_results}</ul>{/if}
{/exp:low_variables:options}
<select name="options">
  {exp:low_variables:options var="my_site:my_multi_var"}
    <option value="{my_multi_var:data}"{selected}>{my_multi_var:data_label}</option>
  {/exp:low_variables:options}
</select>
