Using $ this if not in an object context
I am creating a function to display a blog. So I created the show blog function, but it keeps giving the error "Using $ this if not in object context"
Class Blog{
public function getLatestBlogsBig($cat = null){
$sqlString = "SELECT blog_id FROM jab_blog";
if($cat != null)
$sqlString .= " WHERE blog_cat = " . $cat;
$sqlString .= " ORDER BY blog_id DESC LIMIT 5";
$blog = mysql_query($sqlString);
while($id = mysql_result($blog,"blog_id")){
$this->showBlog($id); //Error is on this line
}
}
function showBlog($id,$small = false){
$sqlString = "SELECT blog_id FROM jab_blog WHERE blog_id=" . $id . ";";
$blog = mysql_query($sqlString);
if($small = true){
echo "<ul>";
while($blogItem = mysql_fetch_array($blog)){
echo '<a href="' . $_SESSION['JAB_LINK'] . "blog/" . $blogItem['blog_id'] . "/" . SimpleUrl::toAscii($blogItem['blog_title']) .'">' .
$blogItem['blog_title'] . '</a></li>';
}
echo "</ul>";
}else{
while($blogItem = mysql_fetch_array($blog)){
?>
<div class="post">
<h2 class="title"><a href="<?php echo $_SESSION['JAB_LINK'] . "blog/" . $blogItem['blog_id'] . "/" . SimpleUrl::toAscii($blogItem['blog_title']);?>"><?php echo $blogItem['blog_title'];?></a></h2>
<p class="meta"><span class="date">The date implement</span><span class="posted">Posted by <a href="#">Someone</a></span></p>
<div style="clear: both;"> </div>
<div class="entry">
<?php echo $blogItem['blog_content'];?>
</div>
</div>
<?php
}
}
}
}

I don't understand how you can go to this error / line with the code you posted, since you have to be in object mode to reach this line. Is getLatestBlogsBig () declared static in the code you actually ran?
Using $this->myFunction()
inside a static function doesn't work. Use instead self::myFunction()
. Just keep in mind that myFunction () must be a static function
