Synopsis

Common behaviour and list of (error) messages that might occur

Description

Tag extensions, like FlexForm, cannot hold any html in its arguments.

<_input type="text" value="hello<br>how are you" />

The above example will simply not be rendered. This is how MediaWiki tags work. You can use the following syntax, it at least will not break. It is another way of writing tag code.

{{#tag:_input||type=text|value=hello<br>how are you}}

The HTML will be filtered out. However, with the new Parsoid Parser that is introduced, do not use the {{#tag:}} method anymore. It will give unpredictable results as Parsoid renders these tags in no particular order.

Here's a list of common error messages that might occur, with a brief description of what the problem might be.

Message Type Why Possible solutions
Can not find template _email shown when the page mentioned in the template cannot be read or parse by the API check page name if it exists or not miss-spelled
not a secure form form shown when the sec option is set to true and the form has been manipulated after form submit
Secure fields not complete form shown when the sec option is set to true and files with type is secure (not to be manipulated with) are incomplete after a form submit
Did not receive a session token from the form form shown when a secure token that is generated by FlexForm did not come with a form submit
Form session expired form shown when the time between a form render and the actual submit has taken to long Change the config option form-timeout-limit to a higher number in seconds ( default 7200 secs = 120 mins = 2 hours )
No return found form shown when a form has been submitted but FlexForm cannot find a page to return to after handling the form
no captcha details reCaptcha shown when a form with a recaptcha has been submitted, but no recaptcha information can be found in the form
No requests form shown when a form has been submitted, but FlexForm could not find any valid request Usually this means the action parameter of a form is invalid.
Cannot find user to connect to file upload form
PHP move uploaded file error (file-handling) upload and canvas shown when a files or files are uploaded using FlexForm, but FlexForm cannot store them in the defined temp folder Make sure you set the FlexForm config : $wgFlexFormConfig['file_temp_path'] = "";

to a path where FlexForm has write rights. If you leave this empty, FlexForm will try to temporarily store the uploaded files in its own extension folder in the uploads folder. You can also check to see if this folder has write rights.

Error messages in the browser's console

Uncaught (in promise) ReferenceError: wgFlexFormSecure is not defined (FlexForm.general.js) JavaScript error. This message may show if you forgot to set $wgParserCacheType = CACHE_NONE; in your LocalSettings.php file. Some features, such as instances, may not work without it.
Uncaught SyntaxError: redeclaration of let ffDecryptObj (FlexForm.general.js) JavaScript error. Same as above.
SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data at line [...] column [...] of the JSON data (FlexForm.general.js) This may happen if you have set your config options for debugging in such a way that any PHP warnings are printed, in turn mangling the JSON output expected by FlexForm. It is generally not a good idea to permanently use settings like ini_set( 'display_errors', 1 ) or error_reporting( E_ALL ) in a live environment.
