Wiki articles in category Tips

在经过畅K网的实战后,总结一下在Yii的项目中会经常用到的组件和一些基本的使用方法,分享给大家,同时也给自己留个备忘录,下面我以代码加图片说明.

I used Zaccarias excellent article as the base http://www.yiiframework.com/wiki/145/cjuidialog-for-create-new-model/

Solution

First follow the wiki above to create all the required code. Then make the following modifications in your...

The two most commonly-used base classes in most Yii applications are CController and CActiveRecord, each extended to your own particular models and controllers.

• First of all, You have to find out the class of the desired icon, so visit the http://getbootstrap.com/2.3.2/base-css.html#icons

1. Create an Active Record Behavior that builds the criteria for the search() method and attach it to your model
2. Modify the search() method of the model to merge the behavior's criteria in with the rest of the searchable attributes
3. Modify the _search form view to add the date range inputs

Let's say, for example, that you are developing a blog or some kind of CMS and you want to track the number of times each post was viewed (maybe to show a list of the most viewed ones).

Simple as that. I have placed this action in my extension folder like:

in Yii versions previous to 1.1.9 exceptions was handled differently during ajax request and displayed by CApplication::displayException(). This way the exception message displayed on ajax requests could not be customized.
The message for the CGridView delete request with YII_DEBUG set to true l...

I guess this is a tip on how to execute some code before every action in a controller, because I will tell you how I did it and maybe you can use the idea in your project.

There are situations in which Active Record will generate nonsense queries from what a nieve Yii user might think is reasonable code. One such situation is a CActiveDataProvider using CDbCriteria to get data from parent and 1:n child table with a condition on the child table.

Sometimes we need some complicated view to be displayed (such as generating complicated table). Most people suggest that in MVC the View must be as simple as possible (don't have too much loops, etc). So what we have to do is to hide away the complex code by putting it at somewhere else. The following are few places options to keep the function:

Suppose to have two models: Users and Emails. You do not want to store email in a Users model. And User can have 0 or many emails. This is the form generated to create a new user (just username).

We often need to display a success page after the user has submitted a form without problem. We may show some welcome message after a user registers a new account. There are many ways to implement this workflow. In this article, I will explain a method that exploits flash messages.

My article Display the full record in a CJuiDialog uses ajax to view a record in dialog on clicking the 'view-icon'.

Often happens to have the need of change a part of the page with ajax.

After Installing Yii Users and Rights to Newly Created Yii app we have to assign dynamic roles to a user at the time of user creation .

// In Yii 1.x $form = $this->beginWidget('CActiveForm', [

'id' => 'order-search-form',
'method' => 'get',

]); echo $form->textInput($searchModel, 'id'); echo CHtml::submitButton('Find', ['class' => 'btn btn-primary']); $this->endWidget(); `

Developing custom Grids and ListViews for my new CMS I was facing a small challenge: If I was to update/delete/batch delete items of my Grid, how would I return to the current page view?

This artical is related to allow user to filter CGridView with date range using datepicker on submit button. Here I use Yii Cookie to preserve date in datepicker textbox after submitting the form.

The official Yii project site now supports OpenSearch. This means you can customize your browser's search box to enable direct search of the content in yiiframework.com. For example, by entering a Yii class name in the browser's search box, the corresponding class API page will be shown in the browser.
