Hello group!
I have created a new views filter handler and it is working, but the labels on the values are missing.
I am sure that I have simply not called them, but i'm not sure how to do it. My handler_filter.inc file is preparing the values with this:
function get_value_options() {
if (isset($this->value_options)) {
return;
}
$this->value_options = array();
$choices = array(
"0" => array(
"#title" => "title 1",
),
"1" => array(
"#title" => "title 2",
),
"2" => array(
"#title" => "title 3",
),
"3" => array(
"#title" =>"title 4",
),
"4" => array(
"#title" => "title 5",
),
"5" => array(
"#title" => "title 6",
),
);
foreach ($choices as $stat => $info) {
$options[$stat] = t($info->item);
}
$this->value_options = $options;
}So the values populate the exposed filter properly, and the query is correct, but the dropdown box in the filter has 6 blank rows.
Is there another function I have to use to send values to the form?
Thanks!

Basic PHP code error
I can't remember the API details, but just looking at your code, it seems obvious that the PHP won't put anything into values of the options array.
In the foreach loop, each $info is an array containing just the '#title' elements.
But you try to access $info->item, which is wrong on two counts:
a) $info is an array, not an object
b) $info does not have an 'item' field.
Try changing that line to:
$options[$stat] = t($info['#title']);
As I said: this is just fixing the basic PHP - no guarantees that you've got the API right.
Well here's the baffling part
Well here's the baffling part - I am SURE the PHP is off as you say, but it is returning the correct value to the query...or is that a coincidence because I want the value to be 0 thru 5 - but labeled otherwise? I'll give the PHP fixes a try and see how it responds.
Thanks!
Correct keys but no labels
Hi Tara. Yes, you are setting the array keys "0" - "5" correctly from $stat, but the values, which are used for labels, will be empty. I'm not really sure why you've created a complex array of arrays with #title elements, because this just makes it harder to read and is unnecessarily complex. The statement "$this->value_options = array();" is also completely redundant (although "$options = array();" before the foreach loop would be good practise). I'm guessing you've adapted a code example somewhere, but if you're just creating a static set of options the whole method can be simplified to:
function get_value_options() {
if (isset($this->value_options)) {
return;
}
$options = array(
"0" => t("title 1"),
"1" => t("title 2"),
"2" => t("title 3"),
"3" => t("title 4"),
"4" => t("title 5"),
"5" => t("title 6"),
);
$this->value_options = $options;
}
And I'm not sure explicitly setting the keys to "0" - "5" makes any difference either as they would default to 0-5 and probably be handled the same:
$options = array(t("title 1"), t("title 2"), ...);Andy
You're awesome - that totally
You're awesome - that totally works! I knew my PHP was wrong.
I decided to keep the keys, even though they are the same by default, because of the relevance to the actual numbers in my application. If I have cause to reassign those values in the future, it will be obvious where to adjust them in this filter, as well.
Thank you so much - I really appreciate your expertise!
