Dplvar: Difference between revisions

'''Sets one''' symbolic variable name and assign a value:

<pre>

{{#dplvar:set|varname|valueofvar}}

</pre>

'''Sets multiple''' symbolic variable names '''and assigns''' values to them (one after the other):

<pre>

{{#dplvar:set|name1|value1|name2|value2|..|..}}

</pre>

'''Assigns''' a value '''only if the variable is empty / has not been used''' so far:

<pre>

{{#dplvar:default|name|value}}

</pre>

'''Returns''' the current value of the variable:

<pre>

{{#dplvar:name}}

</pre>

{{note|The variables can be set and retrieved from an article page or from templates used in that article.}}

<pre>

{{#dplvar:set|a|x|b|y|c|<!--empty-->}} {{#dplvar:default|a|aaaa}} {{#dplvar:default|c|cccc}} {{#dplvar:default|d|dddd}}

</pre>

{{#dplvar:set|a|x|b|y|c|<!--empty-->}} {{#dplvar:default|a|aaaa}} {{#dplvar:default|c|cccc}} {{#dplvar:default|d|dddd}}

'''Result:'''

* a={{#dplvar:a}}

* b={{#dplvar:b}}

* c={{#dplvar:c}}

* d={{#dplvar:d}}

'''Notes:'''

* Variable "c" was set to "cccc" because it was set but with an empty note (empty value).

* Variable "d" was set to "dddd" because it was not already set.
