json

===Name===
_edit JSON content
===Type===
_edit
===Synopsis===
'''Introduced in FlexForm version 1.1.43'''. Using a form to edit pages that have content with JSON.
===Description===
How to edit JSON content pages in the wiki with FlexForm.

The edit function is very similar to editing template content, we will brake down the differences here.

===Parameters===
'''_edit'''

'''target''' = Target page ( title or page id ) that needs to be edited

'''mwformat''' = "json". Tell an edit that we are working with JSON

'''template ''' = This argument has been kept to keep editing a template wiki page and editing a JSON page similar to each other.
Name of the template differs from editing template content and now has two options : json and jsonk. 
*'''json''' : When you create a JSON page with _create, every new named array will also get a unique id, called '''ffID'''. The following example tell FlexForm to find a certain ffID and then find a named value ( so the key ) called Title. FlexForm will then check if the submitted form has an input with the same name the "Title" and use it's value to add to the JSON.

Example JSON:
<syntaxhighlight lang="php">
{
    "Coats": {
        "ffID": 1669192355,
        "Title": "The Body protector",
        "Type": "Bodywarmer",
        "Color": [
            "blue",
            "pink"
        ]
    }
}
</syntaxhighlight>
Example EDIT:
<syntaxhighlight lang="php">
<_edit target="Json_test_result" format="json" template="json|ffID=1669192355" formfield="Title" />
</syntaxhighlight>
If you do not have a ffID, but do have something else in the JSON that is always unique you can use those instead of a ffID. For example, if you know the '''Type:"Bodywamer"''' is unique in this JSON, you can edit the '''Title''' of the JSON this way :
<syntaxhighlight lang="php">
<_edit target="Json_test_result" format="json" template="json|Type=Bodywarmer" formfield="Title" />
</syntaxhighlight>

*'''jsonk''' : This option lets you traverse down a JSON manually. You tell FlexForm exactly what part of the JSON you want to edit and what value of a form input field to use. The following example uses the same JSON example from above and we tell FlexForm to go to '''Coats->Title''', then take the form input of type '''Title''' and put that value in the JSON.
<syntaxhighlight lang="php">
<_edit target="Json_test_result" format="json" template="jsonk|Coats.Title" formfield="Title" />
</syntaxhighlight>
You can also use a different input in your form to use as the new value
<syntaxhighlight lang="php">
<_edit target="Json_test_result" format="json" template="jsonk|Coats.Title" formfield="Alternative title" />
</syntaxhighlight>
You can even traverse into unnamed values like so :
<syntaxhighlight lang="php">
<_edit target="Json_test_result" format="json" template="jsonk|Coats.Color.0" formfield="Title" />
</syntaxhighlight>
This will change the first Color array value into the value of the form field Title.
'''formfield''' = Name of the key in the JSON. When using template type json, then the formfield in the form should have the same name

'''value''' = [optional] Don't read the value from the form field, but use this value explicitly

'''mwslot''' = [optional] Name of content slot to use. Defaults to main content slot

===Note===

* You can have multiple _edit's in a form all doing different tasks.
* If you omit value, then the value of the form will be used (so what a user has filled in).
