The Content Management System Hooks (CMS Hooks) API is for users wishing to display various output from a WIKINDX database into a CMS (Content Management System). It requires some minimal configuration in the Admin > Configure panel.
The following assumes the path to the WIKINDX is https://wikindx.test/ – if not, adjust the path accordingly.
With a browser go to the page https://wikindx.test/cmsprint.php. If you get the message “CMS feature disabled”, you still have to unlock the CMS feature. If you get the message “Unknown action” you are ready use it.
In the examples below, we assume you use a CMS written in PHP, as most are, but the approach remains valid for any program capable of using the HTTP protocol.
In the appendix you will find two basic functions to help you write your first queries. This code uses the cUrl extension (to be activated in the php.ini configuration file if it is not done).
It is strongly advised not to use file_get_contents() or fopen() to make your requests (allow_url_fopen option need to be activated for that). These functions do not provide a means of debugging the code and are susceptible to attacks allowing the execution of arbitrary code. That’s why we provide the curl_get() function as an appendix.
During development you can check that a response is correct by checking cUrl and HTTP error codes. When all goes well cUrl returns code 0 and HTTP 200. It is rare that cUrl returns an error unless its configuration is not adapted to your network (e.g. mandatory proxy). However, you may frequently encounter the following HTTP errors:
curl_get() and curl_post()).The CMS Hooks API has two family of queries:
The API only uses two HTTP verbs GET and POST.
Sending a GET or POST request consists of calling a URL with parameters called queryString. The queryString first parameter (case sensitive) is always preceded by a question mark, the following by an ampersand. The name of a parameter is separated from its value by an equal sign. When special characters appear they must be escaped (this should not be the case because the expected values are numeric in our case).
Examples:
https://wikindx.test/cmsprint.php?param1=value1
https://wikindx.test/cmsprint.php?param1=value1¶m2=value2
https://wikindx.test/cmsprint.php?param1=value1¶m2=value2¶m3=it%27s+value+3
When the request uses the POST verb, we also add a body encoded with the method application/x-www-form-urlencoded (RFC1738). This is information that we want the server to process in addition to parameters. The curl_post() function is written to support this encoding transparently.
The rest of the document describes the verb, the combinations of parameters and the body to send, to obtain the desired result.
The following parameters are valid in all queries.
action is required and must have valid values (case sensitive) ; This parameter indicates what type of response you expect. The values are described later.
mimetype is optional and can take values (case sensitive) php (default) or json. This parameter conditions the format of the data returned. To read serialized PHP, use the unserialize() function, for json use json_decode().
bibStyle is optional and select the bibliographic style used for formatting resources. If this parameter is omitted or its value is wrong the style configured in admin panel will be used. Accepted values are the identifier of a style in uppercase. The APA style is always available, the other styles delivered with WIKINDX may not be installed (ABNT, BRITISHMEDICALJOURNAL, CFB, CHICAGO-AD, CHICAGO-FTHARVARD, IEEE, MLA, TURABIAN, WIKINDX).
language is optional and select your preferred locale used for formatting resources. If this parameter is omitted or its value is wrong the locale configured in the style will be used. Example of accepted locale: en, fr, de_AT, etc.
In all cases, the return from WIKINDX comprises zero, one or more resources matching the queryString parameters inside an array.
We describe here the operation of the parameters common to these actions, then the actions and the exceptions if necessary with examples.
action is required and must have valid values among : getAll, getResource, getCategory, getSubCategory, getKeyword, getCreator, getPublisher, getCollection, getAbstract, getNotes, getQuote, getParaphrase, getMusing, getRecent.
id is required, excepting getAll and getRecent actions, and must have valid values. The id you wish to use may be found directly in WIKINDX (if you’ve set your WIKINDX Preferences to view the CMS pop-up window). You can specify multiple ids separated by commas.
limit is optional. e.g. &limit=10 in the queryString will limit
the results of any list to 10. limit will be
ignored if action=getResource or action=getAll. The default is unlimited, which is not really unlimited because requests have a maximum size and execution time that depends on the server configuration of requested WIKINDX.
order is optional. e.g. order=year in the queryString will
display a list ordered by publication year. Possible values are
creator, year, title, and timestamp. The default is creator. getAll action always use timestamp order.
When using getKeyword, getCategory or getCreator, you may have
a further parameter of sqlMethod=and which allows you to return
results, for example, where each resource belongs to all requested
categories. By default, the resources in the result match any one of the
requested categories. Ditto for keywords and creators.
When getting notes, quotes, paraphrases or musings, only public ones are returned.
The output is a string representing serialized PHP array or JSON array.
Example of JSON response:
{"95":"de Sainte-Marie, A., & du Fourny, H. (1733). <em>Histoire g\u00e9n\u00e9alogique et chronologique de la maison royale de france et des grands officiers de la couronne, de la maison du roy et des anciens barons du royaume<\/em>. Vol. 7. 75 - Paris: Compagnie des Libraires."}
Example of PHP response:
a:1:{i:95;s:263:"de Sainte-Marie, A., & du Fourny, H. (1733). <em>Histoire généalogique et chronologique de la maison royale de france et des grands officiers de la couronne, de la maison du roy et des anciens barons du royaume</em>. Vol. 7. 75 - Paris: Compagnie des Libraires.";}
To access this array, you will need to use the following code:
$array = unserialize($response);
$array = json_decode($response, TRUE);
The contents of $array may be like the following example:
[13] => Back, M., & Des, D. (1996). Micro-narratives in sound design: Context and caricature in waveform manipulation. Retrieved March 12, 2004, from <a href="http://www2.hku.nl/~audiogam/ag/articles/micronaratives.htm" target="_blank">http://www2.hku.nl/~aud ... cles/micronaratives.htm</a>.

Note that, depending upon the bibliographic style chosen, the results may contain HTML tags and entities (as in the above example). The key of each array member is the resource ID.
You can then loop through this array in order to format and print the individual items as you wish. An example might be:
foreach($array as $resourceId => $item)
{
print $item . "<br>";

WIKINDX may be used to format a series of citations within a block of CMS text that uses the CMS replacement tags. The CMS replacement tag may be automatically generated for pasting into the CMS text by using the WIKINDX CMS pop-up window if you have set the CMS hyperlink to display in your WIKINDX preferences. The citation style, by default, uses the style set in the WIKINDX admin panel.
If your CMS text block containing the replacement tags is:
Chion states that: "Blah, blah, blah" {ADD_BIB_ITEM:3:314} but in a later article corrects this by saying: "Bleah, bleah, bleah" {ADD_BIB_ITEM:89:22-23}.
the output from WIKINDX (assuming the current style is APA) may be:
Chion states that: "Blah, blah, blah" (p.314) but in a later article corrects this by saying: "Bleah, bleah, bleah" (Chion 2001, 22-23).
The replacement tag may have further parameters: it is recommended to use the CMS replacement tag generator in WIKINDX for greatest accuracy.
There are several steps in creating the replacement tag code in your CMS, sending the text block to WIKINDX and receiving it back:
if (strpos($text, "{ADD_BIB_ITEM:") === FALSE)
{
return;
}
preg_replace() to reformat your particular CMS replacement
tags to a format WIKINDX will recognize (using [cite]...[/cite]).
For example, with the CMS replacement tags in the example above,
you should use:$text = preg_replace("/\{ADD_BIB_ITEM:(.*)\}/Ui", "[cite]$1[/cite]", $text);
Using the example above, this code will produce:
Chion states that: "Blah, blah, blah" [cite]3:314[/cite] but in a later article corrects this by saying: "Bleah, bleah, bleah" [cite]89:22-23[/cite].
Write the new $text to a temporary file on your web server.
Send a POST to WIKINDX where you give the text to parse as a value of text body parameter.
$response_array = curl_post("https://wikindx.test/cmsprint.php?action=parseText", ["text" => "Belle journée [cite]22827[/cite] [cite]22828[/cite] pour une promenade [footnote]J'aime particuliérement le bord du lac[/footnote]"]);
$string back to your CMS.echo $response_array["response"];
Note the following:
The response will contain not only the formatted text block but will
also contain an appended bibliography of the citations in the text.
Where the current style is an in-text citation style such as APA,
this bibliography is separated by <br><br> – if your CMS uses
similar HTML code for line breaks and you wish to be able to split this
bibliography from the text for some reason, you should replace all
occurrences of <br> with a unique string prior to sending
it to the WIKINDX and then split the result on <br><br> before
reverting that unique string back to <br> and finally printing
the result back to the CMS. If the current style is a style using
footnotes such as Chicago, the WIKINDX result contains the formatted
text, the required footnote citations and the appended bibliography.
Splitting the WIKINDX result on <br><br> will produce an array
of three members, the first being the text block, the second being the
footnotes and the third being the bibliography. For example, you might
use the following code:
$text = preg_replace("/\{ADD_BIB_ITEM:(.*)\}/Ui", "[cite]$1[/cite]", $text);
$text = str_replace('<br>', 'IAMAUNIQUESTRING', $text);
$response_array = curl_post("https://wikindx.test/cmsprint.php?action=parseText", ["text" => $text]);
$split = preg_split("/(<br \/>){2,2}/i", $response_array["response"]);
$text = str_replace('IAMAUNIQUESTRING', '<br>', $split[0]);
$footnotes = $split[1];
