Strange Empty Array Behavior

[xProteuSx]

I am working with the Amazon API, and I am trying to display a default image if a product does not have an image associated with it.  The query is coming back as an array.  Typically, each product image array looks like this:

 

$d = SimpleXMLElement Object ( => http://ecx.images-amazon.com/images/I/51aUIul6XjL._SL160_.jpg [Height] => 160 [Width] => 112 )

 

The code goes like this:

 

if ($d=$E->MediumImage) 
            	{
                $iu=$d->URL;
                $ih=$d->Height;
                $iw=$d->Width;
                
                echo count($d);
                
                if (strlen($iu) > 0)
                	{echo "<center><a href='$url' target='_blank'><img src='images/amazon_noimage.jpg' width='175' height='175' border='0'></a></center>";}
                else
                	{echo "<center><a href='$url' target='_blank'><img src='$iu' width='$iw' height='$ih' border='0'></a></center>";}
            	}

 

However, images/amazon_noimage.jpg never shows up (even though it is linked correctly, as I've tested this link).  I have tried the following:

 

if (strlen($iu) > 0)

if (count($iu) > 0)

if (strlen($d->URL) > 0)

if (count($d->URL) > 0)

if (isset($d))

if (!isset($d))

etc ...

 

If I display the following, where there is no image, I get nothing displayed:

 

echo $iu;

print_r($iu);

echo $d->URL;

etc ...

 

However, if there is an image, I get a link, such as the following:

 

http://ecx.images-amazon.com/images/I/51c2BFpDN0L._SL160_.jpg

 

There seems to be NOTHING that I can do to trigger the 'ELSE' part of the if statement.  This is a total enigma to me ... any ideas??

Your logic is inverted. If strlen is more than 0 then you show no_image, invert it mate.

 

It should be:

 

if (!strlen($iu))

Yeah, also doesn't work.  I'm really baffled.

[silkfire]

Try var_dump(strlen($iu))

[xProteuSx]

Returns nothing if $iu is empty.  Doesn't even return a 0.

Got it!

 

This is what I was originally trying:

 

if ($d=$E->MediumImage) 
            	{
                $iu=$d->URL;
                $ih=$d->Height;
                $iw=$d->Width;
                
                if (!strlen($iu))
                	{echo "<center><a href='$url' target='_blank'><img src='images/amazon_noimage.jpg' width='175' height='175' border='0'></a></center><br />";}
                else
                	{echo "<center><a href='$url' target='_blank'><img src='$iu' width='$iw' height='$ih' border='0'></a></center><br />";}
                    
                $image = $iu;
            	}

 

What I should have been doing, and what works is:

 

if ($d=$E->MediumImage) 
            	{
                $iu=$d->URL;
                $ih=$d->Height;
                $iw=$d->Width;
                
                echo "<center><a href='$url' target='_blank'><img src='$iu' width='$iw' height='$ih' border='0'></a></center><br />";
            	}
            else
            	{echo "<center><a href='$url' target='_blank'><img src='images/amazon_noimage.jpg' width='175' height='175' border='0'></a></center><br />";}
