      Contact form 7 File Upload (cf7 file upload) Shortcode Generator

      Shortcode Generator


      Sample Shortcode (file upload example)

      [file* your-image]

      Contact form 7 file upload shortcode


      File Tag Options

      id:(id) id:some-id id attribute form file input tag.
      class:(class) class:some-class-here class: the attribute value of the input element.  One or more class is possible, like [file your-file class:col-md-2 class:m01 class:pt-1].
      filetypes:(filetypes) filetypes:gif|jpg|jpeg|png Add acceptable file types after filetypes:   Multiple file types are separated with (pipe) ‘|’ character.
      limit:(num) limit:2043576
      Maximum upload file size.  (i.e., like this: [file your-file limit:1.5mb])

      Acceptable File Types

      Contact form 7 default acceptable file types are jpg, jpeg, png, gif, pdf, doc, docx, ppt, pptx, odt, avi, ogg, m4a, mov, mp3, mp4, mpg, wav and wmv.

      Attach File to Mail

      Just go to WP-admin > contact form 7 ( created form) > mail > file attachments add your file input tag as in image.

      You can add more input field one by one like [your-image][your-image2] like that.  Mostly developer forgot to add file attachment tag to file attachment section. So Contact form 7 file attachment not sending or not receiving attachments is a common problem.


      File Upload Validation

      File type and size validations are inbuilt.  jpgpng,jpeg, gifpdfdocdocxpptpptxodtavioggm4amovmp3mp4mpgwav, and wmv are default file extensions. Customize is possible just add filetypes: in the shortcode.

      Example: [file your-file filetypes:png|jpeg] 

      File type not allowed message will get ( you are not allowed to upload files of this type ) If we upload gif, zip or any other file type (in this example).


      File upload size limit

      1048576 bytes (1 MB) is the default file size limit. Customize file size with limit: option. The default number is in bytes but we can add by Mb or Kb. We can see an error message, “The file is too big” if we upload a file bigger than the limit.

      Example : [file your-file limit:2Mb]


      Image Upload Dimension Validation

      CF7 image upload width and size validation code. Add filter for ‘wpcf7_validate_file‘ .

      [file* your-image filetypes:gif|jpg|jpeg|png]

      Add the following code in your theme functions.php file or custom plugin file.

      Here minimum width and height 300px.


      Contact form 7 file upload not working?

      Have you got an error message, “There was an unknown error uploading the file”?

      We can fix it by following the steps.

      First step:

      Check wp-content/uploads/wpcf7_uploads folder is writable (755 – 777 ) or not. It should writable folder.

      Make sure your wpcf7_uploads should writable. For Linux and Mac OS, We can change folder permissions by the following command.

      Please try with 777, if it is not working. But 777 is not good practice.

      Second step:

      Check your PHP maximum upload file size. We can check the maximum file upload size in wp-admin > Media > Add New , We can see “Maximum upload file size: (num) MB”. The maximum upload file size should greater than your upload file size (Contact form 7 file shortcode size).

      Method 1: Change maximum upload size with a php.ini file

      Add or change the upload_max_filesize, post_max_size, and memory_limit as bellow in the php.ini file.

      Now you can upload a maximum 20Mb file. You can change this value according to your needs.

      Method 2: Change maximum file upload size with a .htaccess file 

      Add the following lines of code in your root .htaccess file. You can add the last part of your .htaccess file.

      Method 3: Change maximum file upload size with wp-config.php or selected theme functions.php file

      Add the following line of codes in the wp-config.php or theme functions.php file.


      File Upload Path

      By default wp-content/uploads/wpcf7_uploads is temporary upload file path. Files will delete immediately after few seconds. You can change the temporary folder name byWPCF7_UPLOADS_TMP_DIR  constant in wp-config.php.


      How to save the attached file to the server (Develop CRM)?

      Install the column-based database addon. You can save submission to the external or internal database. It will automatically create new tables for each cf7 form and separate MySQL columns for each input field.

      Does Contact Form 7 data and files save to the database?

      We can’t save submission data without additional extensions. We can use column-based database addon or CFDB7 plugin to save submissions to the MySQL database.


      Where do Contact Form 7 Submissions go?

      We can catch post data by action hook. But it needs advanced knowledge in programming. We can use column-based database addon or CFDB7 plugin to save data.


      Get uploaded files by code

      Save uploaded files by custom plugin or theme functions.php file. We can catch uploaded files by wpcf7_before_send_mail action hook and WPCF7_Submission class instance.  WPCF7_Submission class is a singleton class. It means it instantiates only one time. We can access it like an object by function. Check the following example code.

      We can copy for move uploaded the file by move_uploaded_file  PHP function before sent mail. This file will automatically delete after the sent mail.


      Customize file upload validation error messages

      Go to contact form 7 form > messages tab. Then set the custom message in the input field.
