# Required input error & empty variables

 * Hi
 * We have been happily using CF7 happily for almost a year, and without an identified
   reason the plugin stopped working.
 * 1) Form validation pops an “input is required” error even though the required
   input is filled.
 * 2) When disabling input requirements, the form is sent successfully but the message
   received contains blanks instead of the inputs, and the files aren’t attached
   to the mail.
 * The AJAX request sent upon submitting the form looks as follows :
 *     ```
       POST 200 /wp-json/contact-form-7/v1/contact-forms/762/feedback?_locale=user
       ```

 * Response (when field requirement is activated) :
 *     ```
       {
          "into":"#",
          "status":"validation_failed",
          "message":"Un ou plusieurs champs contiennent une erreur. Veuillez v\u00e9rifier et essayer \u00e0 nouveau.",
          "posted_data_hash":"",
          "invalid_fields":[
             {
                "into":"span.wpcf7-form-control-wrap.your-email",
                "message":"Ce champ est obligatoire.",
                "idref":null,
                "error_id":"-ve-your-email"
             }
          ]
       }
       ```
   
 * I’ve noticed `_wpcf7_posted_data_hash` is empty, perhaps that might be part of
   the issue ?

 * I experienced a similar error. Never go a reply. Then I found if I change other
   elements on the page, it worked again. Almost like other text on the page affected
   the cf7 code.

 * [@blazmate](https://wordpress.org/support/users/blazmate/) Thank you for stopping
   by, I tried to delete everything from the page leaving only the CF7 shortcode
   but it sadly didn’t change anything.

 * After several tests, I noticed the validation / empty fields bug only appeared
   when +4 files were used on the form.
 * I installed a multi file upload plugin and used it instead, which allowed me 
   to get around the bug.
 * I marked this topic as resolved, even though obviously the bug is still there.
