Yii PHP- Property is not defined - php

Question

I'm managing a site built on the Yii Framework and very randomly started to get the following error. Not exactly sure how or why this started happening since the source hasn't been touch.
Appreciate any help. Thanks!
CException

Answer 1

Here is your clue :
#3 /data/www.zoomiezoom.com/protected/views/feature/_form.php(74): CHtml::activeTextField(Object(feature), 'mobile_hero_img', Array)
You are pointing to a field in your feature model that does not exist.
It's there in the model. Is is in the feature table, and are you pointing to the correct model in the form.

Answer 2

I am guessing that you are trying to access a property of a model which extends CActiveRecord.
This means that:
Either you HAD defined this property (mobile_hero_img) and now it is removed
OR
You changed the database schema by dropping a column (mobile_hero_img) from a table (the table that your model class relates to).

Answer 3

It looks like an issue from your DB field.
Did you add a new input field "mobile_hero_img" in the form without adding the field it to the database? Please provide the schema of your "feature" table.

Answer 4

For everyone struggling with "Property is not defined" issue I have one suggestion: check your model's rules() definition and framework's version because there's a bug introduced in Yii (1.1.16) which leads to this error if there is additional space at the end of attributes' list:
// author_id WILL NOT WORK!!
array('app_id, group_id, author_id ', 'required'),
This is fixed in Yii 1.1.17.

Answer 5

The "Property n is not defined" issue can also occur if you have set (text) type of a field and in your model while defining a property, you may have defined it as a boolean or integer.
For example, the below is wrong for text type property.
* #property boolean $billing_address
The right definition will be
* #property string $billing_address
Sometimes there is a small mistake that takes hours to be traced.

Answer 6

I had a same issue. Everything was perfect in the Model class but the problem is still on. Restart the server or SQL does not help. At last, I clear the protected/runtime/cachexxxx.db file, then everything working fine.
I modified the tables with migrate file, and sometimes got error so maybe something is mixed.

Answer 7

My problem was solved when I upgraded to yii 1.1.17
