i created a view that displays my homepage fine but now a modification is needed: i load 2 fields (images) in my view but need to only display one of those, depending on the value of a third (date) field and today's date. if date field is later than today, show image y and if its earlier than today show image x. this kind of logic cant be done in a view.
so in my template.php id like to output x or y as $vars['img'] in the preprocess_page function. im just wondering, how do i get at the values of those fields? its not a node but a list of node teasers.
the function gets passed &$vars but a print_r of those just shows the html output.
custom sql seems not the way to go.
when i load the view, i just get the html it outputs but (i think) i need the raw data to make the date comparison.
thanks for any pointers!
I'm sure there are some ways to do this, some more hackier than others. I would:
Make a template specific to your view
Create a preprocess function for the view and create a boolean variable, by checking which img that should be displayed.
Lastly I would alter the template slightly by making an if statement that checks if it should display img x or y.
This solution is pretty easy and straight forward, the downside is that it's not completely general as you most likely will need to know the names of the cck field names you are using. It's doubtful you would be able to generalize this anyways.
Edit:
To clarify a bit. You can look at the general views template that's being used, it will give you some insight as to how views prints the different fields. Generally getting at the fields is usually not a big problem when you have the $node object. The reason is that cck adds the fields to the $node object so you can access it there. I believe you can do something in the line of $node->field_[the_name] to get to the field. I would suggest that you use the devel module if you don't already and do a dpm($node) somewhere in the template where you loop through the nodes. That will enable you to see what has been defined on the $node object. It shouldn't be a big problem to print the img from there.
How about using preprocess_node() instead?

Update: With the help of the answerer below I figured out how to do this. Basically I used a WP Query to get users and their user metadata and I sorted and placed the data in a for each loop in a table.
I'm new to PHP and I need some help. Basically I want to create a leaderboard with different user data. I want to display it in an html table.
This is kinda what i want:
Username GamiPress Points Time since last login
And I want the table to be populated with these data amongst others automatically. I want two versions one that is sorted with the 15 users who have the most points and one that sorts on the 15 users that logged in last.
Can someone point me to the right place on how I can best implement this?
I basically want to create the GamiPress Leaderboard add-on that I, unfortunately, can't afford, but with some extra fields.
There are multiple steps to do if you want to achieve this:
1) Add meta field to your users, so you can store the points. For example you can use "Advanced Custom Fields" plugin for this.
2) Write a function for adding points to this field. Define when this function will be fired.
3) Query the users ordered by that meta value and display it (get_users($args) might be useful).
4) For the Last-Login value you can use a plugin (google Wordpress Last Login) and write another Query and order results by that meta field. You can also write this by your own, here is a link I found: https://www.wpbeginner.com/plugins/how-to-show-users-last-login-date-in-wordpress/
I don't know if this is what you were looking for.
Or did you want to see an example code how you use a wp query and display data in html table?
I basically have a content type named "articles", and in this content type there is a reference field (that let me put unlimited data) called authorsref and a text field which as well let's me add as many as I want.
Both of this fields are called "authors".
What I want to do is move a specific reference field, to the text field, and then delete that reference field.
So for example, there are a hundred articles already, there are actually thousands and let's say 40 of them have a reference field with the author test1 amongst other reference fields and let's say as well that 60 of those hundred articles have as well a reference field of test2.
what I need to do is to somehow go over all the articles and where test1 and test2 reference fields are present, move them from the reference field authorsref to the text field authors.
I am as well a newbie and I have been trying to get this to work for the last three days and I just don't know how.
Please help, and thanks so much!
I think you need to use hook_update_n + batch.
hook_update_n - With this hook you can update some values in your DB.
Batch - you need to use batch for operations that may take a long time. (You don't want to time out PHP, you wont worry about it with batch).
Some examples here and here.
I have some processing inside my WordPress loop, and I want to "cache" the results so that the next time the post is displayed I can use the pre-processed info. The obvious place to store the results is as post metadata.
I have therefore incorporated a number of Update_post_meta calls into my code, along the following lines:
update_post_meta($imagePostID, "imageMeta", $imageMeta);
In this the value of $imagePostID is just the numeric Post ID, which I have already used to retrieve other metadata, so that's OK. I have also confirmed that the code is getting called at the right point.
However, the values are not getting saved, and it looks like for some reason the updates are just being ignored.
Does anyone understand why this is, and if there's any way to get the behaviour I want?
Thanks,
Andrew
I need to create a block with eg the latest comments on the site.
when using views, concegui select the data I wanted, but the problem is that I need to edit the output of view (specify the html). I tried to make a tpl, but the fields when they get to this, are already formatted ([#markup]). also tried to make a block programmatically by accessing the fields of view, via $comments = views_get_view('last_opinions');, but so the fields do not bring content, but for example, ids (for referrals), or integers (in the case of dates), ....
basically, how to change views output?
views->your view->advance(third panel)-> Theme: Information -> click Information ->choose tpl as per your requirement and find $row which actually prints your output
I have two views that I would like to combine into one.
The first view shows all items of X where company ID = Y. This is to give preferential sort to the client first, and then everyone else.
So I created a second view, all items of X, where company ID != Y.
I created it as an Attachment to attach to the first view, but I don't think I got the intended result.
How can I combine these views so the first view results are listed first, and then the second view is too, using the same pager, filters, and arguments?
Is there any way of achieving this without programming it?
From a MySQL point of view, the order-by-field syntax would be the appropriate way to handle this. Example:
SELECT * FROM tickets ORDER BY FIELD(priority, 'High', 'Normal', 'Low');
It would be great if there is a module that add this kind of functionality to Views, but AFAIK, it does not exist.
If you want to solve this without programming, I think you can use the rules module to automatically set the 'sticky' checkbox on nodes where company ID = Y. With that in place, you can order the View on the sticky value.
Along the lines of the 'sticky' idea, if you didn't want to override that, maybe you could add a checkbox field to the company type -- isClient. Make it false for everyone except the client, and sort by that.
I haven't done this, but maybe you need to create both versions as attachments, and attach them both to another display...?
for drupal 5 there was views union. Someone started something for D6, but I don't know how far they got.
http://drupal.org/node/275162
Create the second view as an attachment and attach it to first.
Set all Inherit arguments, Inherit exposed filters and Inherit pager to Yes.
how is the client parameter passed to the view? as an url argument? if so, you can create your second view like i outline here and then select the exclude the argument option on the appropriate location.
usually the easiest way to achieve this is with a small hook_query_alter, but that requires a small amount of programming.
A little bit later... but I've found a better solution using only the Views module:
Create a Block View with that shows the first list that you need ("all items of X where company ID = Y")
Create another View that must be a "Page view" with the second list (all items of X, where company ID != Y)
In the "HEADER" settings of this second view, click "Add" and select "Global: View area".
In the "View to insert" list, select the first you have created (and check "Inherid contextual filters" if you are using it)
And that's it!
