How do I select a sub-set of items from a view
|
|
To select just a sub-set of the items, specify a Condition, or set of conditions, you can then parameterise that in the include statement or URL. So for example, if you set Condition 1 to "Category" and "LIKE" then you can specify a parameter of "cmd[5]=c-1-News" to set the first condition on View 5 to "News" so that it would list any item with a category containing the string "News". This condition could be set in either the Include statement or the URL e.g.
<!--#include virtual="/aa/view.php3?vid=5&cmd[5]=c-1-News"-->
or in the URL.
?cmd[5]=c-1-News&.....
If there are special characters in the search term, i.e. dashes (as in E-mail) or spaces then quote it, and escape the quotes, for example to select a category=Social Ecology would require a URL of the form:
conds[0][category........]=%22Social%20Ecology%22
(%22 is a double quote (") and %20 is space). If you are constructing this URL from somewhere else and do not know what could be in the field then make sure to quote and urlencode the string.
