I have a singleton database object in a global file at the top of my
document. In most other locations I am able to access it just fine, however
in my footer I want to loop through a properties list for links (I am saving
links to a database, each with its own properties).
Here is the code snippet that is giving me trouble:
footerlinks.inc.php:
<?php
$result = $db->query('SELECT * FROM `links` WHERE `category` =
\'footer_navigation\';');
$total = $db->affected_rows;
Here you use affected_rows as a class property to assign a value to a
variable.
if ($total > 0)
{
$Link = new Link();
$count = $db->affected_rows($result);
Here you call affected_rows as a class method. And from looking at your
Database class. affected_rows is a property not a method. So that
explains the undefined method error.
$i = 0;
while ($row = $db->fetch_array($result))
{
$properties = $Link->setLinkProperties($row);
$link[$i] = '<a ';
foreach ($properties as $prop)
{
$link[$i] .= $prop;
}
$link[$i] .= '>';
$row['text'];
$link[$i] .= '</a>';
$i++;
}
$j = 0;
while ($j < $link)
{
echo $link[$j];
if ($j < $count)
{
echo ' | ';
}
$j++;
}
}
?>
The $Link->$Link->setLinkProperties() method is defined in
Link.class.php:
<?php
class Link {
public function setLinkProperties($rows)
{
if (!empty($row['href']))
{
$properties['href'] = 'href="' . $row['href'] . '" ';
}
if (!empty($row['class']))
{
$properties['class'] = 'class="' . $row['class'] . '" ';
}
if (!empty($row['style']))
{
$properties['style'] = 'style="' . $row['style'] . '" ';
}
if (!empty($row['title']))
{
$properties['title'] = 'title="' . $row['title'] . '" ';
}
if (!empty($row['name']))
{
$properties['name'] = 'name="' . $row['name'] . '" ';
}
if (!empty($row['target']))
{
$properties['target'] = 'target="' . $row['target'] . '" ';
}
if (!empty($row['rel']))
{
$properties['rel'] = 'rel="' . $row['rel'] . '" ';
}
if (!empty($row['onclick']))
{
$properties['onclick'] = 'onclick="' . $row['onclick'] . '" ';
}
if (!empty($row['ondblclick']))
{
$properties['ondblclick'] = 'ondblclick="' . $row['ondblclick']
. '" ';
}
if (!empty($row['onmouseover']))
{
$properties['onmouseover'] = 'onmouseover="' .
$row['onmouseover'] . '" ';
}
if (!empty($row['onmouseout']))
{
$properties['onmouseout'] = 'onmouseout="' . $row['onmouseout']
. '" ';
}
return $properties;
} // END OF METHOD setLinkProperties
} // END OF CLASS
?>
Also for reference, the method query() in my database class sets a value for
$affected_rows:
Database.class.php:
<?php
class Database {
private $server = ''; //database server
private $user = ''; //database login name
private $pass = ''; //database login password
private $database = ''; //database name
private $pre = ''; //table prefix
#######################
//internal info
private $error = '';
private $errno = 0;
//number of rows affected by SQL query
public $affected_rows = 0;
...
?>
This is the error I am receiving:
"*Fatal error*: Call to undefined method Database::affected_rows() in *
/home/mwclans1/public_html/components/footerlinks.inc.php* on line *9*"
Please help PHP gurus!!
