Hi, I've used the following code for a contact form on my website, I've two q's that maybe someone can help with. (I'm no expert at php btw, I found this a couple of years ago.)
Is there a way without captcha to reduce spam coming back?
Also, after the php, the html shows confirmation of the data submitted in the form. The item listed under workshop is a check box from the web form page. There are 9 check boxes, but this only shows the last checked box (if you know what I mean ie, there could be all 9 checked but only the last one comes back as a result. How do I get round this problem?
Am I better to shelve this code for something else do you think?
The html on the web form page:
<form action="workshopenquiryformproc.php" method="post" id="enquiryform">
<fieldset>
<dl>
<dt>
<label for ="name">Name:</label>
</dt>
<dd>
<input type = "text" name="name" id="name" tabindex="1" />
</dd>
<dt>
<label for ="email">Email Address:</label>
</dt>
<dd>
<input type = "text" name="email" id="email" tabindex="2" />
</dd>
<dt>
<label for ="telno">Tel. No.:</label>
</dt>
<dd>
<input type = "text" name="telno" id="telno" tabindex="3" />
</dd>
<dt>
<label for ="yourlocation">Your Location:</label>
</dt>
<dd>
<input type = "text" name="yourlocation" id="yourlocation" tabindex="4" />
</dd>
