if...else help

[tommyinnn]

should be simple..right?? well, for some reason I can't figure this out, not sure what to google either!

 

in most cases, I have no problem with if/else commands,

but what if the variable is NULL, but

 

if($image === "NULL")

 

but NULL doesn't work

 

neither does if($image === " ")

or

if($image > NULL)

 

etc., etc.

 

 

it's a image from a API,

if there is not a image (image url)

then display nothing

if there is, display the image

 

Does anyone know of any other code that may help??

 

 

here's what the XML file looks like when there is no image

 

<ReferencesCount>49</ReferencesCount>

<ImageUrl/>

<FirstName>John</FirstName>

 

and what it looks like if there is a image

 

<ReferencesCount>186</ReferencesCount>

</ImageUrl>

<FirstName>Jonathan</FirstName>

Well, first you're using the exact comparison, when really a normal comparison (==) would do fine. Next, "NULL" shuld be NULL, without quotes. Finally, why not just use the is_null() function?

Thanks for the response, yes, I tried  if($image === "NULL") ,  if($image === NULL ) ,  if($image === 'NULL') ,  if($image > 1) ,  if($image === 1) , etc, etc, etc...

 

and the is_null()  didn't work either.. I read this entire page http://us2.php.net/is_null 3 times and tried several examples, nothing... any other ideas!???

I suggest try

 

if(!isset($image))

 

or

 

if($image=="")

Later on in your topic you mention an xml file.

What exactly gets stored in the $image var?

could you show the code with what you assing the value to the $image var
