W3TPL/tag/get-let

About

The <get> and <let> tags are very similar, even though conceptually they perform opposite tasks.

• get:
  • retrieves an input or stored value and (ultimately) outputs it to the display.
  • is mostly like <let> with echo and self assumed.
  • does not require a name= attribute.
• let:
  • receives an input value and (ultimately) stores it as a variable.
  • requires a name= attribute.

Options

Both tags have these options in common:

• arg= (input): name of POST field to retrieve as tag input
  • USAGE: form processing
• chr= (input): ASCII number of character to use as tag input
• copy= (input): name of another variable whose value should become the input
• val= (input): value to use as input
