Creating a page content of the type "form" the use of the button "form" -> "Form wizard" produces only the failure message "Request URI is too long".
Links to wizards send quite some data in the query parameters. Compressing this would shorten the URI to a length which is less likely to cause problems with certain IE browsers and web servers with limited URI lengths.

[CLEANUP] Remove unused GET parameter fieldConfig for wizards

Many wizard links contain a lot of parameters for legacy reasons.
We can dramatically shorten those in many cases by removing
fieldConfig from them. After searching for fieldConfig throughout
the core it doesn't look like the parameter is used at all.

This patch removes the parameter from link generation.

Which browser (and version) do you use? What kind of server software (Apache?, other?, version?) Is there a limitation on the URL length set in the server?
I just tried it and got this URL:


This is even longer, but no error about the length.

#2 Updated by anybody no-lastname-given almost 8 years ago

Apache/2.2.9 (Debian) DAV/2 SVN/1.5.1 PHP/5.3.5 mod_ssl/2.2.9 OpenSSL/0.9.8g. With the phpinfo of the install tool I could not find a limit, but I am not very experienced with php.

I tried with Firefox 10.0.2 and IE 9.0.8112.

#3 Updated by Jigal van Hemert almost 8 years ago

There are two settings in the Apache configuration which can cause this error message: LimitRequestFieldSize and LimitRequestLine. Maybe your hoster has decreased the limit? The standard value is 8190 bytes.

In IE7 there was also a limit [2], but since we both tested with FF 10.0.2 it is very unlikely that this is the problem.

Can you check with the hoster / sysadmin?

#4 Updated by anybody no-lastname-given almost 8 years ago

According to my provider there was a limit, which is now changed.

But it would be helpful to insert a hint in the FAQ and very optimal to change the programming to shorter links.

I'm changing this in a feature request for compressing long wizard URLs. Some quick tests revealed the using deflate + base64 decreased the size to less than 40%. The parameters in my example took 2221 characters and after compressing "just" 872.

#8 Updated by Sven Juergens about 7 years ago

Today i had the same Problem with an own wizard, is there maybe a "quick and dirty" patch @Jigal van Hemert ? Or maybe a hint where and how i can use "deflate + base64" ?

#9 Updated by Alexander Wende about 7 years ago

Same problem here. Using IIS 7.5 on Windows 2008 RC2. Table and forms wizard links doesn't work. Is there any workaround?

#10 Updated by Marco Bresch about 7 years ago

All older IE's (<= 8) has the same problem. See "Maximum URL length is 2,083 characters in Internet Explorer", http://support.microsoft.com/kb/208427/en

#11 Updated by sunixzs no-lastname-given almost 6 years ago


a quick & dirty solution could be, if the array-key of the wizzard-config is "RTE" and not "link". Then the param "fieldConfig" is not set:

Example TCA-part of the wizzard:

    <RTE><!-- not "link" -->

Typo3 6.1.6 \TYPO3\CMS\Backend\Form\FormEngine Line 3983

if ($wid != 'RTE') {
    $params['fieldConfig'] = $fieldConfig;

URL before: 9485 characters
URL after: 1117 characters

#12 Updated by Tobias Pierschel almost 6 years ago

We ran often in this anoying issue and its a real show stopper. Could there be a fix soon? We would pay 100 EUR for fixing that problem.

#13 Updated by Christof Hagedorn almost 6 years ago

Could someone provide the lowest reasonable values and for typo3 necessary values for


in the apache config?

#14 Updated by Alex Kellner over 5 years ago

Still exists in TYPO3 6.2.
One of the reasons why powermail has no edit link in FlexForm :(

#15 Updated by Jens Vollmer over 4 years ago

This one drove me nuts. It's more a very dirty hack than a real solution, but setting $params['fieldConfig'] to empty worked for me in my Extension and TYPO3 6.2 for the edit wizard. The wizard has to be configured with "module" instead of "script" in TCA.


if ((string) $wConf['type'] == 'popup' && $wConf['module']['name'] == 'wizard_edit') {
    $params['fieldConfig'] = '';
