Jason, Thanks for that, but I'm still getting a syntax error - see attached screenshot.
I've done the following change:
Prior to change:
<span>
<input id="DOB" name="DOB" type="text" value="<?php echo $row_rsMembers_Update['memberDOB']; ?>" class="formTextfield_Medium" tabindex="6" onblur="hideServerError('DOB_ServerError');"/>
After change - adjustment to code:
<span>
<input id="DOB" name="DOB" type="text" value="<?php echo(date("d/m/Y", strtotime($row_rsMembers_Update["memberDOB"])); ?>" class="formTextfield_Medium" tabindex="6" onblur="hideServerError('DOB_ServerError');"/>
Where have I gone wrong?
