Well, listening to the logic:

 

If the session variable 'area' contains nothing (empty string), than it will return the string 'selected'. So it will display: "Selected>Area" or similar into the html, the tag would make it selected.

If the session variable "area" is blank then that option will be selected.

Ok so just to clear it up, would it physically display the word 'selected' or would it just display the word area

[PHP Monkeh]

It would make that option in the drop-down menu selected by default.  Though it's actually wrong as it should be selected="selected" for valid mark-up.

selected="selected" is the proper way to do that.. But what it does is if that is contained in any given option that option is selected by default.

 

example

<select name="example">
<option value="var1">Option One</option>
<option value="var2">Option Two</option>
<option value="var3" selected="selected">Option Three</option>
<option value="var4">Option Four</option>

 

in the example, the option "Option Three" will be selected by default.
