First off goto https://post.craigslist.org/fgl/S/bfs/none/x If you use firebug... you'll see that the email divs look like so... <div><span class="req">Reply to: </span></div> <div> <input style="color: rgb(0, 0, 0);" tabindex="1" class="req df" id="FromEMail" name="FromEMail" size="30" value="Your email address" maxlength="60" type="text"> <input style="color: rgb(0, 0, 0);" tabindex="1" class="req df" id="ConfirmEMail" name="ConfirmEMail" size="30" value="Type email address again" maxlength="60" type="text"> <br> <div id="oiab"> <label title="no email address will appear in your posting - be sure to include other contact info!"> <input name="U2FsdGVkX181MDc.3NTA3Nz:9NTJ_1Npm3DneflCae-m:fPpsL0EpYh9vxv.yrILgV0m" value="A" id="A" tabindex="1" type="radio"> hide </label> <label title="craigslist will anonymize your email address"> <input name="U2FsdGVkX181MDc.3NTA3Nz:9NTJ_1Npm3DneflCae-m:fPpsL0EpYh9vxv.yrILgV0m" value="C" checked="checked" tabindex="1" type="radio"> anonymize (will show as: <a href="mailto:sale-xxxxxxxx@craigslist.org">sale-xxxxxxxx@craigslist.org</a>) </label> <sup>[<a title="how does anonymize work?" target="_blank" href="http://www.craigslist.org/about/anonymize">?</a>]</sup> </div> <br> </div> <input class="point" name="U2FsdGVkX181MDc3NTA3Nxx_3a04vnsqhjgQF7OmIoVvXouCtMhGEVXIwZ36GoLC0CEosKz0rJc" value="U2FsdGVkX181MDc3NTA3N5Ly63lLGjkCVt5bfrlbwhSDI1JdCnzZolOichYD_L2C3S6tQXAuACM" type="hidden"> Code (markup): If I change the value of the fields with php or javascript and submit the form, all data is considered good except the emails. Craigslist is doing those emails in a different manner and I am not sure how. If I enter the email manually I cannot see it anywhere in the firebug html code, If I entered it into a field, it should be in the document and should show up somewhere in the HTML code of firebug...right? Anyways, I'd appreciate some help on this as I am stuck, thanks!
