I have a Zend_Form with multiple Multicheckbox element, the thing that I want is to give them all the same name: categories[].
When I add multiple elements like this:
$this->createElement('multiCheckbox', 'categories[]')
->setLabel('Category 1')
->addMultiOption(1, 'Subcat1')
$this->createElement('multiCheckbox', 'categories[]')
->setLabel('Category 2')
->addMultiOption(2, 'Subcat2')
etc...
Only the Category 2 checkboxes are displayed.
Seems that Zend has the element name as leading. Currently I workaround this with different element names but this isn't really workable at all.
How can I solve this?
that's not how you use multiCheckbox,
use
$multicheckbox->addMultiOptions($zone);
see here a similar example addmultioption array problem in Zend
Ended splitting them up in separate groups.

I'm new with liquid and ruby, but I would like to create a custom filter in a collection, to filter by metafields. I already have:
A dropdown in the collection.liquid, with the values I would like to filter for.
When selecting a filter, it goes to a link like: https://myshop.myshopify.com/collections/my-collection/my-filter . Basically it is like the tags, but with my filter instead
However, since it is a custom filter and not a tag, I get no results. I'm wondering where is the query that displays all the products (or filters) is in the code. I know that it depends on the theme, but I'm using the default theme: launchpad-star.
Not sure if I could do it this way or with a link like: https://myshop.myshopify.com/collections/my-collection?filter_by=my-filter , in which case, I would also need where should the logic go.
I've looked at the forums already and found two closed tickets with no responses: https://ecommerce.shopify.com/c/ecommerce-design/t/using-metafields-to-create-filter-drop-downs-in-collection-liquid-187513 and https://ecommerce.shopify.com/c/ecommerce-design/t/using-metafields-to-create-filter-drop-downs-in-collection-liquid-134401 .
Thanks in advance
Probably not the best solution, but this is what I did to solve the problem:
I changed to the second option of the url, so when a user selects an option in the combobox, it is sent to a URL like: myshop.myshopify.com/collections/my-collection?filter_by=my-filter
In product-grid-item.liquid, I'm getting the metafield value of the product and displaying it as a class, and hide all the products as default. In the collection.liquid I read with javascript the value of the parameter (filter_by) and remove the "hide" class of the products with the value of the filter_by as class, so it gets displayed.
I feel that it is not very clean, but it is working as expected. Problems with this solution:
* Not displaying all the products and then filtering them
* I need to display all the products to avoid pagination, which could be a big problem if I have a lot of products.
If anyone could post a better solution, welcome!.
I have a model which contains emails with some other fields.
I want a custom filter in Yii CGridView's advance search which when applied, lists only Invalid Email IDs (using regular expression '^[A-Z0-9._%-]+#[A-Z0-9.-]+\.[A-Z]{2,4}$')
Note: I dont want to add any column in CGridView
I hope to help you out,
you will need several things
the line for filtering in the column of your choice...(i recommend you create a new attribute for this, ask me in comments if you want to know more why.) this goes in the cgridview of course:
'filter'=>CHtml::activeCheckBox($model, $attributeEmail)
the condition in your search of function that brings up the model.
Supposing you have a criteria inside your search in your model wich help you with your filtering what you need is ...
if($this->EMAIL == TRUE)
{
$criteria->addCondition("\"t\".\"EMAIL\" email NOT LIKE '%_#__%.__%'");
}
Why not to use regex and make a KISS approach ? better read this first...
Sql script to find invalid email addresses
I'd be glad to hear your comments it is interesting question for yii dev's btw
I am attempting to assign a unique id to each table row in Yii's CGridView.
Preferably something like $data->id from the database table.
I have been unsuccessful at adding an id attribute to each rendered <tr>.
Any suggestions would be most appreciated.
CGridView have an option called 'rowHtmlOptionsExpression' , you can declare like the followings to assign row an id
'rowHtmlOptionsExpression' => 'array("id"=>$data->id)',
It's better than hacking into 'rowCssClassExpression'
Good luck !
Modern solution (since Yii 1.1.13)
This is now possible to do using the rowHtmlOptionsExpression attribute, which allows assigning arbitrary HTML attributes to each rendered table row. For example:
'rowHtmlOptionsExpression' => '["id" => $data->id]'
Original answer (earlier versions)
Not directly possible because CGridView does not support it, but there are a couple of straightforward solutions that you can try.
Subclass CGridView (good)
Simply create your own class MyGridView extends CGridView and override the renderTableRow method to spit out ids on every row. Have a look at the stock implementation, which does for the class attribute exactly what you 'd like to do for the id attribute.
Use a CSS class instead (not so good)
Speaking of class attributes, the rowCssClassExpression property can be used to dynamically generate classes out of the box. IMHO this is a bad workaround, but it's there.
You could extend CGridView to add that functionality.
or be a bit hacky with rowCssClassExpression.
'rowCssClassExpression' => '\'" data-id="\' . $data->rowID'
Try the information I posted here:
How to set key value in CGrideView when grid is populated from table-view
In essence, as long as your dataprovider to the CGridview provides the data->id in a form that it understands, it will auto handle the $data->id stuff for you automatically so that it's easily available to javascript.
CGridView.rowHtmlOptionsExpression is undefined
I don't think that we can use rowHtmlOptionsExpression
Could some indicate a working example or a snippet of code for JasperReports regarding ArrayList as a Field in a javabean datasource.
I have a List of Employees. Each Employee has a name field, and an array of Phone with type and number as its fields.
Do i use a subreport for Phones I have not found a working example? Cant seem to compile subreport_jasper file?
Do i use a list component instead...
<c:list ...>
<datasetRun subDataset="Addresses">
<datasetParameter name="Phone">
<datasetParameterExpression><![CDATA[$F{Phone}]]></datasetParameterExpression>
</datasetParameter>
</datasetRun>
This does seems to work either?
Thank in advance
I wrote this article while working with MongoDB. It deals with handling fields that are collections. It should be exactly what you need. (You can just ignore the MongoDB part.)
The key idea is that you use this to pass data to a List or Table or Subreport:
new net.sf.jasperreports.engine.data.JRMapCollectionDataSource($F{PhoneArray})
I am making something that's like that autocomplete tags field for the posts on stackoverflow.com
I want to make it so that when you make a blog post, you can tag it with words in a database, similar to SO.
For the posts, it belongs_to_and_has_many tags
For the tags, it belongs_to_and_has_many posts
However it is a problem for me to do it on the same page because #post would be nil.
How can I implement this?
(If someone can give me the code for the stackoverflow ask question page that would be AWESOME)
I think the problem here is that it seems like you are asking two different questions. Please correct me if I'm wrong on this.
The first question is how you would implement the autocomplete feature to allow users to easily select from a pre-populated list of tags. To answer this, you might refer to spncrgr's answer above.
The second question is how to deal with associating these retrieved tags to the current post. For this you can add additional javascript functionality to your autocomplete solution. When a user selects which tag they want from the autocomplete field, you can do like StackOverflow does and add the tag to a list of tags in a single text field. These can be either space or comma delimited. When you submit the form to create the new post, you can parse this field into it's separate tags:
tags = params[:tags].split(' ')
You can then associate these tags to the model in the Post#create action.
This may not help you at all (or you may have already seen it), but here's a link to a Railscasts' episode on auto-complete:
http://railscasts.com/episodes/102-auto-complete-association
I know it helped me when trying to do something similar.
HTH
It looks for me like you want to generate tags automatically.
You could create
class Post
before_save :create_tags
private
def create_tags
# get your tags somehow
self.tags << Tag.new(:text=>"...")
end
end
method in models/post.rb and build them there.
If you want to search among existing tags for your auto-suggest, you should have it match from Tag.all, as that won't be nil, just as you would collect a group of objects in a select drop down. Not sure about the code for auto-complete, but the tags should be in the Tag table.
