Dialog or Form

[Otto]

Hello Adhemar, hello Shuming,

https://mybergland.com/fwforum/mh_dbf.zip

I have a very simple mod harbour example here.


Call: with index?recno= opens a stored record
only index.prg creates a new record.

For a newcomer, this example is ideal.
If you have any questions, please contact me.

Best regards,
Otto

Hello friends,

Now with 2 lines of code and a universal function of Mr. Rao you can browse every dbf file.
Best regards,

Dear Otto,

maybe you would be so kind as to share a simple sample of a form including an <input type="file"> field for image upload too?

I tried to fill the VALUE of <input type="file" > with the value from the database and take this suggestion in case nothing is selected by the user

but as stated here:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file

You cannot set the value of a file picker from a script — doing something like the following has no effect:

Code: Select all  Expand view

const input = document.querySelector("input[type=file]");
input.value = "foo";
 

how can I prevent the code from overriding existing values in the database with an empty string everytime the user doesn´t select an image?

kind regards and many thanks in advance
Ruth

...please allow me another question:

is it possible to next IF ENDIF logic inside of a CASE statement?

many thanks and kind regards
Ruth

Found the answer ...
I put this IF statement in the existing logic within a CASE and it worked

Code: Select all  Expand view

  case FieldName( n ) == "PICTURE"
            if Empty( hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ))
            else
            FieldPut( n, hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ) )
            endif

Maybe someone can explain to me the difference between what does

Code: Select all  Expand view

 case FieldType( n ) == "L"
                  FieldPut( n, "on" $ hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ) )  

and at the end

Code: Select all  Expand view

  if FieldType( n ) == "L"
                        FieldPut( n, .F. )
                     endif      

Here is the whole block:

Code: Select all  Expand view

for n = 1 to FCount()
      if hb_HHasKey( hPost, FieldName( n ) )
            do case

            case FieldName( n ) == "PICTURE"
            if Empty( hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ))
            else
            FieldPut( n, hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ) )
            endif
           
            case FieldType( n ) == "D"
               FieldPut( n, CToD( hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ) ) )
               
            case FieldType( n ) == "L"
                  FieldPut( n, "on" $ hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ) )    
                 
            case FieldType( n ) == "N"
                     FieldPut( n, VAL( hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ) ) )

             otherwise  

                      FieldPut( n, hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ) )
                     
             endcase  
         else
                     if FieldType( n ) == "L"
                        FieldPut( n, .F. )
                     endif      
             
    endif
 
  next

Kind regards again to all of you,
Ruth

Ruth,

FieldType( n ) == "L"
Determines the data type for a field in the DBF file ( in this case logical )

https://harbour.github.io/doc/clct3.html#fieldtype



FieldPut( n, "on" $ hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) ) )

This is
if "on" is in your Hash than this is .t. otherwise .f.

"on" $ hb_UrlDecode( hb_HGet( hPost, FieldName( n ) ) )

hPost is the value in your FORM.

Best regards,
Otto
