Fatal error: SUHOSIN - Use of preg_replace() with /e modifier

[gttjohnj]

Hi. First I would like to thank you for your AWESOME program. I have been using Formtools for a couple of years and the only problem I have is detailed below.

After logging into Formtools and selecting "View" from the form list then "Edit", I see the first half of the form data but receive the following error message.

Fatal error: SUHOSIN - Use of preg_replace() with /e modifier is forbidden by configuration in /home/****/public_html/formtools/global/smarty/Smarty_Compiler.class.php(270) : regexp code on line 270

My hosting provider has stopped allowing preg_replace() with /e modifier and can't make an exception for me. Is there any patch or workaround available to make formtools work with hosts that don't allow the /e modifier?

Any help would be greatly appreciated.

I may have found a solution to this problem. It seems a lot of hosting companies are blocking /e option in preg_replace for security reasons and it has also been deprecated. I saw recommendations to replace "preg_replace" with "preg_replace_callback". I made the following changes based on some code I found online and it seems to be working for me. At least I am not getting the error message anymore and I can see all my form data. I haven't tested this any further yet so I don't know what unintended consequences may arise. Is anyone else experiencing this issue? Please let me know if this fixes it for you.

File: formtools/global/smarty/Smarty_Compiler.class.php

Replaced line 265
$source_content = preg_replace($search.'e', "'"

with
$source_content = preg_replace_callback($search.'i', "'"

The error seems to cause problems with setting up emails that are sent when a form is submitted too and the above fix doesn't appear to help with that.

When you go to edit a form and click the email tab then click the edit icon for an email, none of the tabs have a button to update or commit changes that you make. On the "Content " tab the HTML template is gone. The "Test" tab is blank.

There is the necessity of different discussions through which you can resolve the errors. Therefore I am suggesting professional essay writing service uk that will give me a long list of all the instructions.
