How To Fetch And Display Multiple Rows? - php

Question

I'm using Magento which is on the zend framework and the following code currently outputs the first row matching the criteria is_read != 1', 'is_remove != 1'. I need to modify this code to output the last 4 table rows that matches said criteria. I tried a few things but none worked. Please Help!
ModuleName/Model/Resource/
public function loadLatestNotice(Mage_AdminNotification_Model_Inbox $object)
{
$adapter = $this->_getReadAdapter();
$select = $adapter->select()
->from($this->getMainTable())
->order($this->getIdFieldName() . ' DESC')
->where('is_read != 1')
->where('is_remove != 1')
->limit(1);
$data = $adapter->fetchRow($select);
if ($data) {
$object->setData($data);
}
$this->_afterLoad($object);
return $this;
}
Here are some other codes that are used...
ModuleName/Model/
public function loadLatestNotice()
{
$this->setData(array());
$this->getResource()->loadLatestNotice($this);
return $this;
}
ModuleName/Block/
public function getLatestNotice()
{
return $this->_getHelper()
->getLatestNotice()->getTitle();
}
Template/
href="<?php echo $latestNoticeUrl ?>" onclick="this.target='_blank';"><?php echo $this->getLatestNotice() ?>

I was able to solve the problem myself, by using the following method.
The first thing i tried to produce is 4 notification table rows instead of 1, is to change ->limit(1); to ->limit(4); and $adapter->fetchRow($select); to $adapter->fetchAll($select);. The issue is, the solution requires more than just changing these 2 values.
ModuleName/Model/Resource/
public function loadLatestNotice(Mage_AdminNotification_Model_Inbox $object)
{
$adapter = $this->_getReadAdapter();
$select = $adapter->select()
->from($this->getMainTable())
->order($this->getIdFieldName() . ' DESC')
->where('is_read != 1')
->where('is_remove != 1')
->limit(4);
$data = $adapter->fetchAll($select);
if ($data) {
$object->setData($data);
}
$this->_afterLoad($object);
return $this;
}
After changing this, the template will stop outputting information, In order for the template to output the new array, you must duplicate some code and remove ->getTitle() line in the block file, then change a few line of codes in the template .phtml file as follows.
ModuleName/Block/
public function getNewFuncName()
{
return $this->_getHelper()
->getLatestNotice();
}
Template/
<?php
$notice = $this->getNewFuncName();
foreach ($notice as $item) {
foreach ($item as $value) {
echo '<div class="notemssg"><p id="notetitle" href='.$value['url'].' >'.$value['title'].'</p><p id="notedate">'.$value['date_added'].'</p></div>';
}
}
?>
Changing the code to properly call and display the array will result it 4 table rows being displayed. the code can be modified to be used and any way you would like to display the info on the fronted.
Hope this helps Someone!
