Display nav list of content is available with php - php

Question

I've got this PHP code:
<div class="connect_wrap <?php echo $this->class; ?> block" <?php echo $this->cssID; ?>>
<?php if(!$this->empty): ?>
<?php foreach($this->entries as $entry): ?>
<div class="entry block <?php echo $entry->class; ?>">
<div class="tab">
<ul class="tabs">
<li class="tab-link current" data-tab="Kunden">Kunden</li>
<li class="tab-link" data-tab="Loesungen">Lösungen</li>
</ul>
<?php
$this->import('Database');
$pName = $entry->field('name')->value();
$result = \Database::getInstance()->prepare("SELECT * FROM kunden WHERE partner=?")->execute($pName);
?>
<?php if($result->numRows):?>
<div id="Kunden" class="tab-content current">
<?php while($result->next()) { ?>
<div class="items">
<a href="{{env::url}}/kunden-detail/<?php echo $result->alias; ?>">
<div class="logo">
<img src="<?php $objFile = \FilesModel::findByUuid($result->logo); echo $objFile->path;?>"width="180" height="135">
</div>
</a>
</div>
<?php } ?>
</div>
<?php endif;?>
<?php
$this->import('Database');
$pName = $entry->field('name')->value();
$result = \Database::getInstance()->prepare("SELECT * FROM solutions WHERE solution_provider=?")->execute($pName);
?>
<?php if($result->numRows):?>
<div id="Loesungen" class="tab-content">
<?php while($result->next()) { ?>
<div class="items">
<a href="{{env::url}}/synaptic-commerce-solution/<?php echo $result->alias; ?>">
<div class="logo">
<img src="<?php $objFile = \FilesModel::findByUuid($result->logo); echo $objFile->path;?>"width="180" height="135">
</div>
</a>
</div>
<?php } ?>
</div>
<?php endif;?>
</div>
</div>
<?php endforeach; ?>
<?php else: ?>
<?php endif;?>
In that code, I've got two DB queries. My problem is, if there is no data for both queries, the div with the class "connect_wrap" should not be displayed.
How can I do that?
Thanks in advance.

Answer 1

do you want to check if the query has data in it and its not empty ? if so try num_rows it will return the number of rows that the query found/affected for example to check if th query returned one or more rows
if($result->num_rows >= 1) {
//do stuf
} else {
// no result found
}

Answer 2

Move the query execution up or preferably: not within the html but in a different file/class. Then add a check before the content_wrap div: if($kundenResult->num_rows >= 1 || $solutionsResult->num_rows >= 1). If you just keep the individual checks like you already have, it will only show the content_wrap div if either or both of the queries return rows of data.
