Magento - Adminhtml - 空白编辑表单，不显示编辑输入字段中的数据

Question

I'm using Magento 1.9.0.1 and i'm working a custom extension.

Right now i'm stuck on the part of creating a admin form. Let me show you.

Here is the grid table in a custom page which i've created in the admin fetching data from custom MySQL table called VivasIndustries_SmsNotification :

When i click on a row with result here is what i get:

As you can see the input fields Receiver, Phone and Date are blank, but they must not be blank. This is an edit form and these fields must hold the data printed in the row in the grid table. Also when i hit save it should save the edited data, but it is not working.

So let me show you what i have done so far:

I have in: /app/code/community/VivasIndustries/SmsNotification/etc/config.xml:

Answer 1

1] I wil give you my code that include most of the functionalities in edit form. Change according to your block/model/helper. "AI" = NameSpace and "Hi = ModuleName".Try below code in your form.php. It will generate edit fields with data.

<?php

class AI_Hi_Block_Adminhtml_Hi_Edit_Form extends Mage_Adminhtml_Block_Widget_Form
{

public function __construct()
{
    parent::__construct();
    $this->setId('hi_form');
    $this->setTitle(Mage::helper('hi')->__('User Information'));
}

protected function _prepareForm()
{
    $model = Mage::registry('hi');

    $form = new Varien_Data_Form(
        array('id' => 'edit_form', 'action' => $this->getData('action'), 'method' => 'post','enctype' => 'multipart/form-data')
    );

    $form->setHtmlIdPrefix('hi');

    $fieldset = $form->addFieldset('base_fieldset', array('legend'=>Mage::helper('hi')->__('User Information'), 'class' => 'fieldset-wide'));

    if ($model->getId()) {
        $fieldset->addField('id', 'hidden', array(
            'name' => 'id',
        ));
    }

    $fieldset->addField('fname', 'text', array(
        'name'      => 'fname',
        'label'     => Mage::helper('hi')->__('First Name'),
        'title'     => Mage::helper('hi')->__('First Name'),
        'required'  => true,
    ));

    $fieldset->addField('lname', 'text', array(
        'name'      => 'lname',
        'label'     => Mage::helper('hi')->__('Last Name'),
        'title'     => Mage::helper('hi')->__('Last Name'),
        'required'  => true,
    ));



    $fieldset->addField('address', 'textarea', array(
        'name'      => 'address',
        'label'     => Mage::helper('hi')->__('Address'),
        'title'     => Mage::helper('hi')->__('Address'),
        'required'  => false
    ));

    $fieldset->addField('country_id', 'select', array(
      'label'     => Mage::helper('hi')->__('Country'),
      'class'     => 'required-entry',
      'required'  => true,

    $fieldset->addField('gender', 'radios', array(
      'label'     => Mage::helper('hi')->__('Gender'),
      'name'      => 'gender',

      'disabled' => false,
      'readonly' => false,
      'tabindex' => 1
    ));

    $fieldset->addField('hobby', 'checkboxes', array(
      'label'     => Mage::helper('hi')->__('Hobbies'),
      'name'      => 'hobby[]',
      'values' => array(
                        array('value'=>'Music','label'=>'Music'),
                        array('value'=>'Reading','label'=>'Reading'),
                        array('value'=>'Writing','label'=>'Writing'),
                   ),
      'onclick' => "",
      'onchange' => "",
      'value'  => '1',
      'disabled' => false,
      'tabindex' => 1
    ));

    $fieldset->addField('status', 'select', array(
        'label'     => Mage::helper('hi')->__('Status'),
        'title'     => Mage::helper('hi')->__('Status'),
        'name'      => 'status',
        'required'  => true,
        'options'   => array(
            '1' => Mage::helper('hi')->__('Enabled'),
            '0' => Mage::helper('hi')->__('Disabled'),
        ),
    ));

    $fieldset->addField('categories', 'select', array(
        'label'     => Mage::helper('hi')->__('Categories'),
        'title'     => Mage::helper('hi')->__('Categories'),
        'name'      => 'categories',
        'required'  => true,
        'values' => array(
                     array('value'=> Mage::helper('hi')->getAllCategoriesArray(true)),
                         ),
    ));

    if($model->getData('profimage') == "")
    {
        $fieldset->addField('profimage', 'file', array(
            'name'      => 'profimage',
            'label'     => Mage::helper('hi')->__('Image'),
            'title'     => Mage::helper('hi')->__('Image'),
            'required'  => true
        )); 
    }
    else
    {
        $path = Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA)."AI_Hi/".$model->getData('profimage');
        $note = 'Browse new image to replace old one.Allowed image type [ "jpg","jpeg","gif","png"]<br/> <a href="'.$path.'" rel="lightbox" onclick="func_loadLightBox(this);return false;" title="'.$model->getTitle().'">
                <img src="'.$path.'" style="width:100px;height:100px;"/></a>';

        $fieldset->addField('profimage', 'file', array(

            'label'     => Mage::helper('hi')->__('Image'),
            'title'     => Mage::helper('hi')->__('Image'),

    }


    if (!$model->getId()) 
    {
        $model->setData('status', '1');
    }

    $form->setValues($model->getData());
    $form->setUseContainer(true);
    $this->setForm($form);

    return parent::_prepareForm();
}

}

Now, we need to change edit.php file to make working save button. Change below code according to your need.

public function __construct()
{
    parent::__construct();
    $this->_objectId = 'id';
    $this->_blockGroup = 'hi';
    $this->_controller = 'adminhtml_hi';
    $this->_updateButton('save', 'label', Mage::helper('hi')->__('Save User'));
    $this->_updateButton('delete', 'label', Mage::helper('hi')->__('Delete User'));
    $this->_addButton('saveandcontinue', array(
        'label'     => Mage::helper('adminhtml')->__('Save and Continue Edit'),
        'onclick'   => 'saveAndContinueEdit()',
        'class'     => 'save',
    ), -100);

    $this->_formScripts[] = "
        function saveAndContinueEdit(){
            editForm.submit($('edit_form').action+'back/edit/');
        }
    ";
}

public function getHeaderText()
{
    if (Mage::registry('hi')->getId()) 
    {
        return Mage::helper('hi')->__("Edit User '%s'", $this->htmlEscape(Mage::registry('hi')->getTitle()));
    }
    else 
    {
        return Mage::helper('hi')->__('New User');
    }
}

}

2] I can't find deleteAction() in /Adminhtml/SmsorderstatusesController.php: Add below code.

public function deleteAction()
{

    try 
    {
        $hiId = $this->getRequest()->getParam('id');
        $hi = Mage::getSingleton('hi/hi')->load($hiId);
        Mage::dispatchEvent('hi_controller_nammer_delete', array('hi' => $hi));
        $hi->delete();
        $this->_getSession()->addSuccess($this->__('User Deleted successfully.'));
    } 
    catch (Exception $e) 
    {
        $this->_getSession()->addError($e->getMessage());
    }

    $this->_redirect('*/*/index');
}

Let me know if you've any issue.

1) You have to load the model and insert its data into the form to show prefilled values. You need to edit method

VivasIndustries_SmsNotification_Block_Adminhtml_Sms_Status_Edit_Form::_prepareForm()

Insert the code below right between lines $form->setUseContainer(true); and $this->setForm($form);

$id = Mage::app()->getRequest()->getParam('id');
$model = Mage::getModel('smsnotification/smsnotification')->load($id);
$form->setValues($model->getData());
