Examples/Parameter: execandexit (example 2)
< Examples
Example
A typical use appears like the following, the execandexit
statement transforms URL args to variables, and the {{#dplvar:set}}
sets the value of DPL_cat
variable to Category:Dessert examples. Note: The double pipe symbols within the #if.
Calling the following page with &DPL_cat=Country examples
would list countries, omitting the &cat
parameter would trigger the error text message (without DPL3 going to the database):
{{#dpl:execandexit=geturlargs}} {{#dplvar:set|DPL_cat|Category:Dessert examples}} {{#dpl: | execandexit = {{#if:{{#dplvar:DPL_cat}}||please specify a category via &DPL_cat= in the URL!}} | resultsheader = Pages in <i>{{#dplvar:DPL_cat}}</i>:\n | noresultsheader = There are no pages in <i>{{#dplvar:DPL_cat}}</i>.\n | count = 2 | category = {{#dplvar:DPL_cat}} }}
Result
{{#dpl:execandexit=geturlargs}} {{#dplvar:set|DPL_cat|Category:Dessert examples}} {{#dpl:
| execandexit = | resultsheader = Pages in {{#dplvar:DPL_cat}}:\n | noresultsheader = There are no pages in {{#dplvar:DPL_cat}}.\n | count = 2 | category = {{#dplvar:DPL_cat}}
}}
