Hi,

1.How to add default value to text area from my hash having one field as default=>"somevalue",how i need to add default value to test area from the hash below.

2.How to add delimiter other than spaces to text area. If I enter multiple value to the text area and submit the data using the form ,the text area multiple values are separated by space delimiter ,where this will fail for me if i have the values like

config data
config values
config data values

where if i use space as delimiter it fails as i getting config and data as separate values.So i need to use any delimiter such as $,in text area, and if user gives muliple entries i will separate using delimiters like $,how to add delimiter to text area.

hash function is
my  @add=(

{
  name=>"comment",
  type =>"text",
  default=>"all",
  enum=>[" "],
  entries=>"single" 
},
{
  name=>"Submode",
  type =>"textarea",
  default=>"all ",
  enum=>[" "],
  entries=>"more"
}
);


[% FOREACH element = add %]
  [% IF element.type == "text" %]
 <input type="text" name="[%element.name %]" value="[%element.default 
+%]" size="58">
[% ELSE %]
<textarea rows="4" name="[%element.name %]" >
</textarea>
[% END %]
[% END %]

1) A <textarea> form element is different from the other <input> elements in that it has a beginning and ending tag, with the 'value' between those. Thus to start a textarea with the value "Howdy!" you would code <textarea>Howdy!</textarea> So it looks like you could add the value in your template by using <textarea rows="4" name="[% element.name %]"> [% element.value %] </textarea> 2) I'm not sure I understand your question. You can 'see' separate values if they are on separate lines in the textarea. You may have to check for CR or LF characters, and to do that you might have to force CR/LF characters by playing with the wrap parameter, such as <textarea wrap="hard"></textarea>	[reply]

More of an HTML question, but just have it print the value between the `textarea` tags .. Note i removed the line breaks -- if you leave them there they will be part of the default value. `<textarea rows="4" name="[%element.name %]" >[% element.default %]</te +xtarea>` [download] As for the second part, it seems like you want to add the '$' or whatever delimiter to `element.default` before you pass it to the template -- may sometihng like `$element->{default} =~ s/\n/\$/sg;`	[reply] [d/l] [select]
