Display rows including empty rows in symfony 1 - php

Question

I'm a newbie in web development, and i want to modify an existing project.I want to display rows including a null value,a default value of zero or the empty one.This is the code in action..
public function executeDetails(sfWebRequest $r) {
if($this->getUser()->hasAttribute('extend_term_ch')) {
$this->getUser()->getAttributeHolder()->remove('extend_term_ch');
}
$this->loan = Doctrine_Core::getTable('Loans')->findOneById($r->getParameter('id'));
$this->debits = Doctrine_Core::getTable('CreditLogs')->getByLoanId($r->getParameter('id'));
}
and in templates
<?php $totalAmount = 0 ?>
<?php foreach($loan->Collections as $i=>$c): ?>
<?php $totalAmount += $c->amount ?>
<tr class="<?php echo ($i%2==0)?'even':'odd' ?>">
<td>
<?php echo $c->mode_of_payment ?>
<?php if($c->mode_of_payment == 'Cheque'): ?>
<?php $cReferencedObj = $c->Cheques ?>
<div class="small_detail info">
<span class="bold">(<?php echo $cReferencedObj->bank ?>, <?php echo $cReferencedObj->branch ?>) <?php echo $cReferencedObj->reference_number ?></span>
</div><br />
<?php endif; ?>
<?php $replaced = $c->getReplacedCheque() ?>
<?php if(!empty($replaced)): ?>
<div class="small_detail info">
Payment for <span class="bold">(<?php echo $replaced->bank ?>, <?php echo $replaced->branch ?>) <?php echo $replaced->reference_number ?></span>
</div><br />
<?php endif; ?>
</td>
<td><?php echo $c->batch_no ?></td>
<td>
PHP <?php echo number_format($c->amount, 2) ?>
<?php if($c->mode_of_payment == 'Cheque' && !empty($c->Cheques->replaced_with)): ?>
<?php $replaced = $c->Cheques->Replaced ?>
<div class="small_detail info">
Replaced with <span class="bold">(<?php echo $replaced->bank ?>, <?php echo $replaced->branch ?>) <?php echo $replaced->reference_number ?></span>
</div>
<?php endif; ?>
</td>
<td><?php echo date('F d, Y', strtotime($c->date_created)) ?></td>
<td><?php echo $c->created_by ?></td>
<td><?php echo $c->date_created ?></td>
<td>
<?php if(in_array($c->mode_of_payment, array('Cheque', 'ATM', 'Direct Bank Transfer'))): ?>
<span class="info">
View Details
</span>
<?php else: ?>
<div class="small_detail info">
Collector: <span class="bold"><?php echo $c->Collectors->lastname.', '.$c->Collectors->firstname ?></span>
</div>
<?php endif; ?>
<?php if(in_array($loan->mode_of_payment, array('Cash', 'ATM')) && $sf_user->hasCredential('COLLECTIONS_ROLLBACK')): ?>
<div class="small_detail bullet_go">
Rollback Collection
</div>
<?php endif; ?>
</td>
</tr>
<?php endforeach; ?>
<tr>
<td colspan="6">Total Paid</td>
<td>PHP <?php echo number_format($totalAmount, 2) ?></td>
</tr>
This will only display rows with data..how about displaying the empty row?For example a person has to pay his debts in 40 days from April 1, 2014 up to March 10,2014, then for some reason, he did not pay April 4, 6, 8 and so on.I want to display those dates 4, and 6 and 8 and display some errors for every date he failed to pay it like "No payment for this date".
