# Preselection in the list view URL¶

If you are linking to the list view from other pages, you can preselect stuff in the URL (by using the variables from the list view filter form):

&tx_seminars_pi1[place][]=1
&tx_seminars_pi1[event_type][]=3
&tx_seminars_pi1[category]=1
&tx_seminars_pi1[country][]=DE etc. (the uppercase ISO 3166 alpha2 code)
&tx_seminars_pi1[city][]=Berlin
&tx_seminars_pi1[language][]=EN (the uppercase ISO 639 alpha2 code)


This also works with combinations of these:

&tx_seminars_pi1[event_type][]=3&tx_seminars_pi1[place][]=3
&tx_seminars_pi1[place][]=1&tx_seminars_pi1[category]=1


You can not only preselect categories, but also specify search phrases directly in the URL. To do so, just add this to the URL of the page that contains the seminars list view:

&tx_seminars_pi1[sword]=searchphrase


If you want to use whitespaces make sure you replace them with %20, e.g.:

&tx_seminars_pi1[sword]=I%20am%20searching%20something


It’s not necessary to have a search field on the list view activated. So you can specify search phrases in the URL to filter your results without offering the opportunity to specify other search phrases.

If you want to specify search phrases for a page by default without specifying parameters in the URL, just enter this to your Typoscript Setup:

plugin.tx_seminars_pi1._DEFAULT_PI_VARS.sword = searchphrase
