It will allow you to display on your blog publications associated with authors and other entities (structures, collections, research projects). All data is fetched from the [HAL’s website](https://hal.science). ## Screenshots * [[ * Global parameters for retrieving publications * [[ * Widget settings * [[ * Example of a page using a shortcode ## Installation #### Requirements: * PHP 7.0 or higher * WordPress 5.0 or higher * cURL extension in php.ini #### Installation/update procedure: 1. Desactivate the plugin if you have a previous version installed. 2. Unzip the archive and put all files into a specific older in the directory **/wp- content/plugins/**, e.g. **/wp-content/plugins/hal**. 3. Activate the plugin via **Appearance/Plugins** menu in WordPress admin panel. #### Pages: 1. In WordPress admin dashboard, go to **HAL** and modify global parameters for retrieving publications on your blog page. 2. Create your page and add the shortcode **[cv-hal]** to fetch data based on the criteria specified in the first step. NB: you can directly add parameters to your shortcode, e.g. **[cv-hal id=2497 type =structId_i]**. For more information, please check the FAQ, our [generic documentation](https://doc.hal.science/afficher-une-liste-de-publications-dans-wordpress) as well as our [documentation on HAL’s API](https://api.hal.science/docs/search). #### Widget: In WordPress admin dashboard, go to **Appearance/Plugins** to configure the widget. ## FAQ ### How can I contact the support team? You can contact the support team at the following email address: [hal.support[at]ccsd.cnrs.fr](https://tah.wordpress.org/plugins/hal/hal.support@ccsd.cnrs.fr?output_format=md). ### How to insert data into my page? Just create a page and put the shortcode **[cv-hal]** in your content. As simple as that. ### What can I do to customize the content from within the shortcode? You can add parameters to your shortcode, e.g. **[cv-hal id=184 type=structId_i]**. Supported identifiers: * **IdHAL (sequence of characters)** = authIdHal_s * **Structure identifier (numeric)** = structId_i * **Collection identifier (sequence of characters)** = collCode_s * **ANR Project identifier (numeric)** = anrProjectId_i * **European Project identifier (numeric)** = europeanProjectId_i To retrieve contact information, add to the shortcode **[cv-hal]** the parameter** contact** taking the values **yes** and **no, e.g. \*\*[cv-hal contact=yes]**. To display the number of documents, use the shortcode **[nb-doc]**. ### cURL * You need to enable the **php_curl** extension. Navigate to **Apache/bin** directory, open the **php.ini** file and uncomment **;extension=php_curl.dll**. ## Reviews ![](https://secure.gravatar.com/avatar/af4a34335e54b44261fe0c5d4ec37bffdcba787b7aef77ed85be15cfc4497f1c? s=60&d=retro&r=g) ### 󠀁[Un bon plugin, qui j’espère s’améliorera encore](https://wordpress.org/support/topic/un-bon-plugin-qui-jespere-sameliorera-encore/)󠁿 [sympythy](https://profiles.wordpress.org/sympythy/) septembre 29, 2021 Le plugin HAL permet très rapidement et simplement d’intégrer une bibliographie dans une page de son site Wordpress (depuis HAL), ainsi qu’une liste des dernières publications. J’espère qu’il évoluera en offrant plus de possibilités de configuration tout en gardant sa simplicité. ![](https://secure.gravatar.com/avatar/11f741ed1c420c05101ba9ef7f5310501a584e132db8fffa46417713ce89b3d5? s=60&d=retro&r=g) ### 󠀁[Excellent plugin](https://wordpress.org/support/topic/excellent-plugin-1891/)󠁿 [micheltam](https://profiles.wordpress.org/micheltam/) septembre 3, 2016 1 reply Il serait sympa que ceux qui mettent de mauvaises notes tiennent compte des évolutions et des correctifs apportés au plugin qui est très intéressant et fonctionne très bien sur la plateforme de blogging scientifique Hypotheses.org Le développeur est réactif et prend en compte les demandes d’évolutions.
