Report problems or ask questions about this version of the plugin here in this topic please.

Upgrading from 4.0.3.19 to 4.0.3.20

The only change that might affect people is that label attribute values are assumed to be plain text, not html escaped text, since the emails need the plain text values and it’s much easier in the plugin to escape the label when showing it in the browser (if needed). In the older versions no escaping or unescaping was done which could cause problems in either email or in HTML.

Bug fixes

• remove leading and trailing spaces from form input
• escape label attribute values when showing the form in the browser (not in email, plain text there)
• remove dependency on zem_contact_submit ‘name’ attribute value for the submit button as this is handled by the zem_contact_form_id nowadays (makes it easier to custom build your own submit button)
• use ISO-8859-1 instead of ISO-8599-1 (typo!) when override_charset is set in the TXP preferences (by default UTF-8 is used)
• add some extra email header escaping. Not to fix header injection, but to filter out ASCII NULL
• use the correct sender email address in the copysender email even if the ‘from’ attribute is set in the zem_contact tag
• some other HTML escaping fixes
• make required=“0” attribute work when used in zem_contact_email tag (thanks Federico!)
• don’t display empty input values in the email
• use TXP built-in email validation checks instead of duplicating code in plugin

Plans for the future

• Built in ‘Multi language pack’ support (which also means making the zem_contact_lang plugin optional)
• Customizable email body layout
• Support for attributes like tabindex
• Requires TXP 4.0.4 or higher to reduce code size.
• …

Solving plugin installation problems

If you get a blank screen or a HTTP 304 or a HTTP 404 error during plugin installation, put the following in a .htaccess file in your textpattern folder (not your website root!) during the install and remove it afterwards:

<IfModule mod_security.c>
SecFilterScanPOST Off
</IfModule>

If you get an error message during plugin installation that reads “malformed or empty plugin code”, you either didn’t copy/paste the entire plugin code (try again!) or your webhost has restricted the maximum amount of text that can be transmitted using a form. In the latter case, try installing the compressed version of the plugin (requires TXP 4.0.4 or higher).

Apparently very few people still use this version with the rather old TXP 4.0.3, because it took almost 3 months before someone pointed out that TXP 4.0.3 does not have a built in is_valid_email() function. If you are still using TXP 4.0.3 (please, please upgrade!), then you can temporarily restore 4.0.3 compatibility by editing the plugin and adding the following code at the end. You’ll have to remove it when upgrading to a higher version:

function is_valid_email($address)
{
  return preg_match('/^[a-z0-9](\.?[a-z0-9_+%-])*@([a-z0-9](-*[a-z0-9])*\.)+[a-z]{2,6}$/i', $address);
}
