Description:

there is a textarea in a form that people seem to enjoy entering 5 spaces in between each line they type. this causes a problem when i print the info on paper that has preprinted info on it. Unlike the normal text box, MAXLENGTH is not an attribute of a textarea. Therein lies my problem

Or if you want to remove blank lines:

s/\n{2,}/\n/g;
If you want to clump everything into a single line (maybe for reformatting it yourself, see Text::Wrap or my Nicely format a list or a string snippet):
s/\s+/ /g;
If you want to cut it to the first 5 non-empty lines:
$text=join("\n",(split(/\n+/,$text))[0..4])
I don't think there is an HTML attribute to restrict the number of lines in a TEXTAREA.

A possible perl solution is removing some of the newlines, like:

s/\n{3,}/\n\n/g;

which will replace three or more newlines in a row with two (two to preserve double-spacing of paragraphs).

In the text of the page, put "X character limit." Then $text = substr($text, 0, X)

You can also add the following as a guide to your form-submitters.

<input value="X" size="3" name="msgCL" disabled> <script language="JavaScript"> <!-- var supportsKeys = false function tick() { calcCharLeft(document.forms[0]) if (!supportsKeys) timerID = setTimeout("tick()",200) } function calcCharLeft(sig) { clipped = false maxLength = 200 //Change this. if (document.creator.signature.value.length > maxLength) { document.creator.signature.value = document.creator.signature. +value.substring(0,maxLength) charleft = 0 clipped = true } else { charleft = maxLength - document.creator.signature.value.length } document.creator.msgCL.value = charleft return clipped } tick(); //--> </script>

Hope this helps
