Hello Monks,
Using Activestate perl, Apache 2and CGI package.
I'm returning variable values from web page form user input.
eg -
$myvariable = $q->param( "myinput" );
I then test for a null value with eg -
if ($myvariable eq ""){ #ie if user didnt fill in field
exit; #don't try to work on a null value
}
Although my scripts work ok I'm filling up my apache error log with drivel like -
"...Use of uninitialized value in string eq at ..."
It seems that an uninitialised variable is not the same as a null variable.
How do I test for an uninitialised variable?
I've hunted through quite a lot of big fat perl books to no avail.
This seems like an embarrassingly dumb question, sorry.
Masters, you are my only hope ....
Thanks

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
