zend-form-element

问题 If I have a form element that has multiple validators attached to it (3 in this example), how would I use addErrorMessage to create custom error messages when each unique validator fails. Is there a way to add a custom message for each validator? $element = new Zend_Form_Element_Text()... $element->.... ->addValidator(...) ->addValidator(...) ->addValidator(...) ->addErrorMessage() 回答1: Typically it's done per validator error message, not per validator... $element->setErrorMessages(array(Zend

问题 I have looked at other questions/Googled this. My problem is that when I submit my form with empty textboxes that have a notEmpty validator, it triggers no error. First, I would like to see if I understand the difference between notEmpty and setRequired . As I understand, the notEmpty validator gives an error if an element is submitted and the value is empty. That is, if an entry does not exist in the POST data (for forms), then it does not generate an error if the element is not required .

问题 I need to add some random html content with text before and after my input field. I know I can use description decorator and set escape option to false - this way I can simply inject arbitrary html chunk as a decorator. But this only accounts for 1 html chunk - I need a second one after input field. If I simply output description decorator again after input field - that will output the same description chucnk. 1) Is there a way to use description decorator multiple times with different

问题 I'm using Zend_Form_Element_File to validate certain file properties. The file input element in question is created dynamically - ie. it can be in the form, but doesn't need to; however, if it is, and a file has been submitted via it, it needs to meet certain criteria. I've encountered the "File exceeds the defined ini size" issue, when the form doesn't contain the file element. Is it an intended behavior? Please bear in mind that the FormUpload should validate for both form elements. I can

问题 I want to add some javacsript to a Zend_Form_Element_Text . At first I thought a decorator would be the best way to do it, but since it is just a script (the markup doesn't change) then maybe a view helper is better? or a view script? It seems like they are all for the same purpose (regarding a form element). The javascript I want to add is not an event (e.g. change, click, etc.). I can add it easily with headScript() but I want to make it re-usable , that's why I thought about a decorator

问题 I needed to show some preexisting data from a table and but needed to disable them to prevent user from editing them. So i disabled them $form -> getElement("elementname") -> setAttrib("disable", true); When I submit the form, I found out, that the form element does not get submitted at all, just because it was disabled. I confirmed this when I tested removing the disable options. What is happening? Am i doing something wrong? How to solve this? 回答1: This is by design, disabled elements do

问题 How to edit the button content of a Button element (of a ZF2 form)? I can set a label, but i would like to insert some html code inside it. $this->add(array( 'type' => 'Button', 'name' => 'submit', 'options' => array( 'label' => 'Modifica', ), 'attributes' => array( 'type' => 'submit', 'class' => 'btn btn-warning' ) )); Thanks 回答1: You can simply use the disable_html_escape label's option. It works for me. $this->add(array( 'type' => 'Button', 'name' => 'submit', 'options' => array( 'label' =

问题 I want to add check for more than one values in where clause. Db_RecordExists just check for one filed. I have read that you can extend zend validate abstract class and you can have your own validator. can I have one little example about this please. Thank you... 回答1: What are you trying to do exactly? To me, you don't even need a custom validator. If you read carefully the source code of Zend_Validate_Db_Abstract you will notice this phpDoc above the constructor: Provides basic configuration
