Common issue: the plugin saves files that are submitted via forms to the database…but I want to save the file to a special directory.<\/p>\n

To do this, you create a filter as described on the page about Changing Form Data Before it is Saved<\/a> but you use the following code.<\/p>\n

Change the values of $formName<\/strong>, $fieldName<\/strong> and $uploaddir<\/strong> to suit your needs.<\/p>\n

function cfdbFilterSaveFile($formData)\r\n{\r\n    \/\/ CHANGE THIS: CF7 form name you want to manipulate\r\n    $formName = 'your-form'; \r\n    \r\n    \/\/ CHANGE THIS: upload field name on your form\r\n    $fieldName = 'form-file'; \r\n\r\n    \/\/ CHANGE THIS: directory where the file will be saved permanently\r\n    $uploaddir = '\/root\/htdocs\/wp-content\/uploads\/path\/to\/save\/dir\/';\r\n\r\n    if ($formData && $formName == $formData->title && isset($formData->uploaded_files[$fieldName])) {\r\n        \/\/ make a copy of data from cf7\r\n        $formCopy = clone $formData;\r\n        \r\n        \/\/ breakdown parts of uploaded file, to get basename\r\n        $path = pathinfo($formCopy->uploaded_files[$fieldName]);\r\n        \/\/ directory of the new file\r\n        $newfile = $uploaddir . $path['basename'];\r\n\r\n        \/\/ check if a file with the same name exists in the directory\r\n        if (file_exists($newfile)) {\r\n            $dupname = true;\r\n            $i = 2;\r\n            while ($dupname) {\r\n                $newpath = pathinfo($newfile);\r\n                $newfile = $uploaddir . $newpath['filename'] . '-' . $i . '.' . $newpath['extension'];\r\n                if (file_exists($newfile)) {\r\n                    $i++;\r\n                } else {\r\n                    $dupname = false;\r\n                }\r\n            }\r\n        }\r\n\r\n        \/\/ make a copy of file to new directory\r\n        copy($formCopy->uploaded_files[$fieldName], $newfile);\r\n        \/\/ save the path to the copied file to the cfdb database\r\n        $formCopy->posted_data[$fieldName] = $newfile;\r\n\r\n        \/\/ delete the original file from $formCopy\r\n        unset($formCopy->uploaded_files[$fieldName]);\r\n\r\n        return $formCopy;\r\n    }\r\n    return $formData;\r\n}\r\n\r\nadd_filter('cfdb_form_data', 'cfdbFilterSaveFile');\r\n<\/pre>\n
A More Sophisticated Example<\/h3>\n
Example where we save the file and add a URL to the file location into the form submission. Based on forum discussion<\/a>. <\/p>\n
This example is good if you have multiple forms to save file from. Here we have a reusable function “saveFilesInForm” and a “cfdbFilterSaveFiles” function that calls it. If you have multiple forms:<\/p>\n
    \n
  1. create a new version of “cfdbFilterSaveFiles” with a unique function name for each form<\/li>\n
  2. Add a new “add_filter” call for each form, passing the name of the new function<\/li>\n
  3. The “saveFilesInForm” function appears only once<\/li>\n<\/ol>\n
