I looked through the archives and couldn't find anything on this.
I have a web form which takes 9 values to create a definition for a table
that would have up to 9 columns.
I made the table so that each form field is submitted as an array so that I
can simply step through each value and create the table definition, so:
<input type=text name="tblcol[]"> (duplicated 9 times)
Now, when I submit the form the resulting array always has 9 elements and
some of those will be empty.
I would like to do error checking in case people didn't fill anything at all
so I thought using if (!count($tblcol)) {.... But that doesn't work since it
always has 9 elements.
Is there a way to find out if an array contains no values even though it has
elements? Sort of like a trim() function on an array to destroy the
elements in the array that are empty.
Is it possible?
