Undefined variable

Please help to resolve this problem. Im not programmer but im really need help to fix this problem.

if( TP_MASONRY )
{
$this->item->text = JFilterOutput::ampReplace($this->item->text);
preg_match_all("/<img[^>]*>/Ui", $this->item->text, $txtimg);
if (!empty($txtimg[0])) {
foreach ($txtimg[0] as $txtimgel) {
$this->item->text = str_replace($txtimgel,"",$this->item->text);
if ( $n == 0 )
{
preg_match_all("#src=\"([\:\-\/\_A-Za-z0-9\.]+)\"#",$txtimgel,$txtimgelsr);
$this->item->img = ( !empty( $txtimgelsr[1][0] ) ) ? $txtimgelsr[1][0] : null;
}

}
}
}

Undefines variable: if ( $n == 0 )

Thanks in advance

 

Change it to:

if (isset($n) && $n == 0 )

 

nope, lose image on front page if use isset or change $n

this script is related for showing images on the front page

 

are you initializing $n somewhere in your code?

did you tried: if($n && $n == 0) ... ?

 

Paste the error message please. Error message is always our square one to go further.
With no error message, all advices you have would be nothing more then crawling in the dark.
