Range search based on price field in drupal - drupal

I have a CCK field price which the user can fill in. I would like to create a search form with dropdown price field with different ranges (such as below 100$, 100$-1000$, more than 1000$). The problem is that the user input is an integer so I cannot achieve range search using filter exposure. The user would have to specify the exact value to perform searching, but this is rather useless. Is there a way ( amodule, etc) to create ranges out of integer values so that the user is able to perform range based search?

Obviously people grab views and CCK for most solutions. But often a small module sith just a hook_menu(), a calback and a theme function will suffice.
In that callback you can perform whatever complex query you want.
Such modules, most of the time, contain less then 100 lines of PHP.
If you know PHP such a functionality might take you less then an hour to build. Whereas writing addons and behaviours for CCK and Views often costs much more.
The advantage of building views and CCK addons, is that your code is better re-usable.

The way I did it in the past was to use hook_form_alter to change that field to a select drop down range (a min and max drop down), then alter the views query if a value was provided.
The other way to do ranged facets would be to explore Apache Solr integration or Search Lucene facets. Keep in mind that its not exactly plug n play tech, though.

To sort out out your price into various categories you need to create a CCK Select list and then populate the list automatically using the Rules module. You need to also hide this select list using content permissions.
I've created a mini-case study on graphing using Rules & Views. As part of the mini case study, it shows you how to categorize the cost field using Rules -- which is precisely what you want. It also shows you how to hide the field using content permissions. Please check the below link for a video:

wordpress custom fields: structured data table

I know how to make custom fields for my custom post types. But I need a pretty complex custom field this time.
I'm making a website about agricultural machinery. There are a lot of types of machines. For every type of machine there are some products available with properties like size, mass, diameter, capacity, ....
Per type there is only one description, one title and one image needed. So my custom post-type machine contains posts (custom type = machines) with the basic information. For every machine I would like to sum up all the different size - mass - capacity - prize information in a table. I know I could just create a html table in the description, but I would really like the data to be structured so I can nicely style it, and eventually even do structured searches for price and stuff.
So ideally I would like to have a custom field that looks a bit like an excel sheet where I can create some columns and add rows per available product in the category. Any ideas how I can do this?
EDIT: I'm trying out the Types wordpress plugin http://wordpress.org/extend/plugins/types/. There's an option to group custom fields together and also an option to allow multiple instances of one field. Would be useful for me if there would be a possibility to allow multiple instances of a group. Does something like that exist?
EDIT: This looks promising. http://wp-types.com/documentation/user-guides/bulk-content-editing-with-fields-table/
I will look into it and maybe answer myself if it turns out to work :)
It seems like wp-types had the solution all along.
http://wp-types.com/documentation/user-guides/bulk-content-editing-with-fields-table/
This is what my custom data table looks like now:
Behind the scenes, all data is not actually saved in a single post. But wp-types allows you to create hierarchical relations between post types, and then provides a way to quickly create sub-posts straight from the parent. That's awesome enough for me.
In my case I created two post types. One called machine-type and another called machine.
machine-type holds all the basic information about the machine (title, description and image) while it's sub-type machine holds the specs for any of the different variants.

Drupal 7 Views : How to reuse one view for multiple fields OR how to let user select which field view displays?

My Task: I have content type which have 100+ different mostly numeric fields (big questionnaire for NGO with yearly reports). For one field I can use Views module to let user select which reports include (for example one year) and display it as nice graph (using for example Views+Charts). I would have to define about 100+ nearly identical views, which differs only by what field data they use.
My Question: Is there any way how to reuse one view definition and just change data from which field id display?
Solutions so far: I found two not really good solutions:
Create one view, export it (using Features or similar way) and then clone this export, rewrite field it uses as source and than add. But this just speed up creating one view for each 100+ fields.
Use module Views Dynamic Fields - it allows user to select which fields to display. But I would still have separate definition how to display for each field, so not much better than add one view for each 100+ fields.
I suggest writing your own Views field display plugin! This is actually all documented within the Views module folder: views/docs/views.api.php. Depending on your fields I'm not sure how you would exactly connect the data to the view.
Another alternative would be to just use a PHP Code field, and figure out a way to programmatically display the data from the field you wanted. The downside to this is that you wont be able to use that field to sort/search on with any filters as far as I know.

Measurement sheets in Drupal 6

I'm doing a project for a surveying company in Drupal 6. Ultimately, employees will need to enter measurements into a new content type. Currently they do it in a big Excel spreadsheet that has a bunch of macros to do calculations between cells (Meters to Feet, m^2, some pricing stuff).
My question is:
How would one go about replicating the functionality of this spreadsheet best in Drupal 6, keeping in mind the amount of data the employees using this system gather varies between projects (I.e., 3-floor house versus 1-floor with basement; etc.).
I have two ideas so far:
Create a new content type and populate it with CCK fields. Use Sheetnode's CCK functionality to drop Sheetnode CCK fields to replicate the spreadsheet exactly. Use Views to display this data other ways.
Create a new content type and populate it with CCK fields. Use Views (and possibly something like Views Calc) to get varying measurement values.
That said, I'm completely open to suggestions outside of these two implementations.
Thank you!
I dont have an answer so much as a caution. I did a project where a number of pieces of content were rendered simultaneously on a page, each piece being in its own node. The down side to multiple nodes is the performance hit you will take having at least one (possibly complex) query per node.
So in this case, if there were many many lines in the sheet, and each line was a node, you might take a pretty heavy performance knock.
This might be acceptable - but I thought I'd give you the heads up.
This might be one of those times where its best to actually create a purpose-built mechanism on-top of the Drupal API instead of using nodes+CCK.
Like I said, I could be being over cautious. It depends on your exact usecase.
HTH!
This seems like the kind of question http://drupal.stackexchange.com was made for...
I ended up doing this with jQuery, Measured Value Field and Flexinode; see: Auto-updating width/length/area using jQuery and Drupal6

How can I specify the number of a instances of a given field in a View

I have standard basic article content type which, amongst other things, contains an image field which is configured to contain an unlimited amount of values.
I'm now trying to create a view that lists some of the fields in this content type but I want to limit the number of images that are returned for this specific field to 3 random images in the list (or less). Is this something that can be achieved right in my view configuration or do I need to do something ninja? I'm not aware of everything that's possible php wise to "rewrite" / "filter" the results of my view but I'm confortable with anything programming related.
I'm using drupal-7 with Views 7.x-3.0-alpha1
Thanks!
AFAIK there is no way through the Views UI to randomize the selections of a grouped field.
I can see two possible ways, in theory to achieve what you want.
Use hook_views_query_alter to alter the SQL query for the view. I'm not sure Views support what you need to randomize the results, but you have the ability to alter the query that views generates, and might be able to randomize it.
Select all results, but using theming to only show the randomly selected options. This could be done in a preprocess function. Views provides several, depending on your display option, hook_views_view_unformatted might be what you need.

Drupal: module, cck or other

I have a legacy PHP form that I'm moving over to Drupal 6. I'm trying to make things easy for me as well as the future admins of the site. The below form is the heart of the old site data. So far in cck I have Locations, in taxonomy I have Countries, now I just need to allow these Species data to be added. I would do it in CCK, but I also want to be able to add N number of Species to each form with all 12 Quadrats of % Cover and Density. (For each species in that location there is % Cover, Density, Flower, Fruit, etc ie alot of data!)
Basically my question is, can this form be accomplished in 1) CCK where the whole form can be filled out on one page, 2) by creating a custom CCK field to enter in a Species (using FormAPI) or 3) bite the bullet and write a custom module with FormAPI fields and keep track of the data in tables myself?
Thanks for your insight.
It can be helpful to think of CCK the way you would an Object Oriented challenge: what are my Things, and how do they relate to each other.
If I'm reading you correctly, you're creating some kind of Botanical Entry type. I gather that Location is set up as a separate type, and that field could be a node reference in BE. (Or perhaps it's just a list in an text field with a drop down widget.) Same thing with Transect and Station. Researchers could be a user reference field.
Then you want to add your species data (the second form). I don't really know what all those fields are for, but I'll bet that interface could be simplified. Species might be a separate CCK type, which you'd connect via node reference, or you could create a custom CCK field type. Either way, you could allow adding more than one of those to a node to get the mulitple entries. If you do the node reference approach, you could probably use http://drupal.org/project/popups_reference to make the adding easier.
HTH
