Forms Processor Parameters

escape

This parameter specifies character(s) you want escaped from all form input data. Escaping means inserting a special character before a character to remove the significance that character would otherwise hold. For instance, suppose you were collecting the form data in a file, with each field separated by a comma (this is called a comma-delimited file, and is accomplished in part by setting the f_field_separator parameter to a comma). If the user typed a comma into a form field, when the field was written to the file the comma in the data would be indistinguishable from the commas which served as delimiters in the data. This could create problems for the program which would eventually try to read the file (it would think there was an extra data item in the file). Provided the program which eventually would read the data file had an "escape" mechanism, you could alleviate this by entering the following line in the form's configuration file:

$escape="x";

• x - The character that you wish the Forms Processor to "escape".
  

Example:

# This example configuration file escapes all "$" and "&" characters,
# then writes the data to a file named "hotstuff.txt" in the www directory.

$escape="$";
$escape="&";
$file="www/hotstuff.txt";
