Hi. Newbie here. I learned PHP a while back and then didn't use it for a while, and now I'm trying to get back into the swing. However, I'm not sure I ever tried before to do what I'm trying now...
In the below displayed code, I'm using form-embedded PHP to produce a "country" drop-down in a simple HTML form.
It's sort of 'working', but in building each "<option..." statement within that created drop-down, I'm also embedding PHP within that stuff (to test any saved value of the field and retain the highlighted/selected value of this field if the form fails edit...this way, the user won't have to re-key all field values) - and that innermost PHP isn't being recognized, I think.
Note: the 'file' that is being read for this test is a very simple file with only 4 records in it. Each of these records has 3 fields (country name, country number, and country code...and these three fields are delimitted by commas).
Here is the code - and the RED stuff is that which is not quite working: (obviously, it's in a test mode - with edits not even in place yet)
TIA, folks.
