Can I change and save the text stored in the database that I see in a text box? But the text field is in the Views tab in a table.

In Views-Tab i have one Table "table_fotos".

Columns list:
fotogalery.bilddaten:Bilddaten
bilddaten_edit:Edit Bilddaten
speichern:speichern
Columns views:
bilddaten_edit:{view:foto_bilddaten_list_field}
speichern:{view:button_speichern}
and this Text-Field: "foto_bilddaten_list_field"
Name:
bilddaten[{var:table_fotos.row.fotogalery.foto_id}]
Value:
{var:table_fotos.row.fotogalery.bilddaten}
​
​
Under the Functions-Tab
Loop: save_foto_bilddaten_loop
Data provider: {data:bilddaten}
Loop body: {fn:update_foto_bilddaten}
and Save Data: : update_foto_bilddaten
Write action: Auto detect
Model: fotogalery
Database table: mytable
Data provider: empty
Data overrides
