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.
