<FileElement :urls="{ uploadTempFile: '...', removeTempFile: '...', removeFile: '...' }" ... />

The urls the file uploader should use for uploading and removing files.

uploadTempFile ​

• Request params:
  • file {File} - the selected file
  • formKey {string} - the form's formKey property
  • path {string} - the element's path using . syntax (eg. user.avatar)
  • ...params {any} - all params defined in params object
• Default: config.endpoints.uploadTempFile.url
• Returns: { tmp: TEMP_FILE_NAME, originalName: ORIGINAL_FILE_NAME }

Called when a file selected by the user should be temporarily uploaded.

removeTempFile ​

• Request params:
  • file {object} - the temporary uploaded file object (contains the response value of temp request)
  • formKey {string} - the form's formKey property
  • path {string} - the element's path using . syntax (eg. user.avatar)
  • ...params {any} - all params defined in params object
• Default: config.endpoints.removeTempFile.url
• Returns: void

Called when a temporarily uploaded file is removed if softRemove is false.

removeFile ​

• Request params:
  • file {string} - the uploaded file's name
  • formKey {string} - the form's formKey property
  • path {string} - the element's path using . syntax (eg. user.avatar)
  • ...params {any} - all params defined in params object
• Default: config.endpoints.removeFile.url
• Returns: void

Called when an uploaded file is removed if softRemove is false.

Deprecated, use the followings instead:

• uploadTempFileEndpoint
• removeTempFileEndpoint
• removeFileEndpoint

<FileElement :methods="{ temp: 'POST', removeTemp: 'DELETE', remove: 'DELETE' }" ... />

The methods should be used by urls. Defaults are:

• temp - config.endpoints.uploadTempFile.method
• removeTemp - config.endpoints.removeTempFile.method
• remove - config.endpoints.removeFile.method

<FileElement upload-temp-endpoint="/upload-file" ... />

The endpoint where files should be uploaded.

It can be a simple url like /upload-file but also an object containing url and method:

<!-- Using an object as endpoint -->
<FileElement :upload-temp-endpoint="{
  url: '/files',
  method: 'POST'
}" ... />

It can be a named endpoint that references an endpoint in vueform.config.js:

// vueform.config.js

export default {
  endpoints: {
    upload_file: {
      url: '/files',
      method: 'POST'
    }
  }
}

<!-- Using a named endpoint -->
<FileElement upload-temp-endpoint="upload_file" ... />

It can be an async function that handles the file upload and returns an object with data:

<!-- Using a function to upload file -->
<FileElement :upload-temp-endpoint="async function(file, el$){
  let data = el$.form$.convertFormData({
    file,
  }) // befomes `FormData` object

  /* upload file */

  return {
    tmp: '...', // the temp file identifier
    originalName: '...', // the original name of the file that will be displayed to the user
  }
}" ... />

If the temporary uploading should be skipped the endpoint should return a string with the filename instead of an object. Eg:

<!-- Using a function to upload file without temp upload -->
<FileElement :upload-temp-endpoint="async function(file, el$){
  let data = el$.form$.convertFormData({
    file,
  }) // befomes `FormData` object

  /* upload file */

  return 'filename.jpg'
}" ... />

If the file(s) should be sent with the all other form data upon submission (completely skipping temp uploading), the endpoint can be disabled with false:

<!-- Using a function to upload file without temp upload -->
<FileElement :upload-temp-endpoint="false" ... />

More info in File Uploads guide.

<FileElement remove-temp-endpoint="/remove-temp-file" ... />

The endpoint where temp file remove requests should be submitted.

It can be a simple url like /remove-temp-file but also an object containing url and method:

<!-- Using an object as endpoint -->
<FileElement :remove-temp-endpoint="{
  url: '/temp-files',
  method: 'DELETE'
}" ... />

It can be a named endpoint that references an endpoint in vueform.config.js:

// vueform.config.js

export default {
  endpoints: {
    remove_temp_file: {
      url: '/temp-files',
      method: 'DELETE'
    }
  }
}

<!-- Using a named endpoint -->
<FileElement remove-temp-endpoint="remove_temp_file" ... />

It can be an async function that handles the remove and receives an object as first param containing tmp and originalName properties:

<!-- Using a function to remove temp file -->
<FileElement :remove-temp-endpoint="async function(file, el$){
  const { tmp, originalName } = file

  /* remove temp file */
}" ... />

More info in File Uploads guide.

<FileElement remove-endpoint="/remove-file" ... />

}" ... />

It can be a named endpoint that references an endpoint in vueform.config.js:

// vueform.config.js

export default {
  endpoints: {
    remove_file: {
      url: '/files',
      method: 'DELETE'
    }
  }
}

<!-- Using a named endpoint -->
<FileElement remove-endpoint="remove_file" ... />

It can be an async function that handles the remove and receives the name of the uploaded file as first param:

<!-- Using a function to remove file -->
<FileElement :remove-temp-endpoint="async function(file, el$){

<FileElement :format-data="(n, v) => ({[n]: /* transformed value */ })" ... />

Formats the element's requestData.

The first param is the element's name, the second is the value. The return value should be an object, which only contains one item with the element's name as key and the transformed value as value.

<FileElement :format-load="(v) => /* transformed value */" ... />

Formats the data being loaded to the element when using load(data, format: true). It receives the value being loaded to the element as its first param and should return the formatted value of the element.

<FileElement :submit="false" ... />

If set to false the element's data will not be included in requestData and will not be submitted.

<FileElement rules="required|max:1024" ... />
<FileElement :rules="['required', 'max:1024']" ... />

The list of rules can be defined as a string separated by | or as an array, where each item should be a single validation rule.

<FileElement field-name="Field name" rules="required" ... />

Sets the name of the field in validation rule messages.

<FileElement rules="required" :messages="{ required: 'Please select a file' }" ... />

Overrides the default messages for the element's validation rules. The value is an object where each key is the name of a validation rule and the value is the error message that will be displayed when the rule fails.

You can override validation messages on form level with messages.

<FileElement :display-errors="false" ... />

Whether element errors should be displayed.

<FileElement :conditions="[
  ['foo', 'bar'],
  'AGE(birthday) > 18',
  (form$) => !!form$?.el$('terms').value
]" ... />

Shows or hides an element based on the provided conditions.

<FileElement label="Label" :columns="{ container: 12, label: 3, wrapper: 12 }" ... />

Sets the size of the container, label and wrapper using the theme's grid system, where the:

• container is the wrapper DOM that contains both label and wrapper
• label contains the label
• wrapper contains the file.

The value of container defines the size of the element's container. 12 will result in full width, 6 in half, 4 in third and so on.

The value of label defines the amount of space the label should take up within the container. If the container is 12 and label is 6 the label is going to take up half the space and the file will the other half (which is calculated automatically). If the container is 6 and label is 6, the label will only take up one forth and the file the rest. In case the label has full width (12) the file will also take up full space instead of becoming zero.

The value of wrapper defines the size of the file wrapper within the space left for it in the container after subtracting the size of the label. If the container is 12 and label is 4 the space left for the file is 8. In this case if the wrapper value is 12 it will take up the full space left for it (which is 8) while if it is changed to 6 it will only take up half the space left for it (4):

<FileElement label="Label" :columns="{ container: 12, label: 4, wrapper: 12 }" ... />
<FileElement label="Label" :columns="{ container: 12, label: 4, wrapper: 6 }" ... />

Note that while the size of the file wrapper changes, the size of extras like a description or error won't be limited to the wrapper's space. Instead it will take up the full space in the container left after subtracting the size of the label:

<FileElement
  label="Label"
  :columns="{ container: 12, label: 4, wrapper: 6 }" 
  description="Lorem ipsum dolor sit amet, consectetur adipiscing elit"
... />

You can set the value of columns as a number in which case the container will receive its value without affecting thedefault stings oflabelandwrapper`:

<FileElement label="Label" :columns="6" ... /> <!-- { container: 6, label: 3, wrapper: 12 } -->

You can as well define column values for different breakpoints using the theme system's breakpoints like sm, md, etc. as keys:

<FileElement label="Label" :columns="{
  xs: { container: 12, label: 12, wrapper: 12 },
  sm: { container: 12, label: 4, wrapper: 12 },
  md: 12,
  lg: { container: 12, label: 2, wrapper: 12 }
}" ... />

Default cumn sizesan be defined globally in vueform.config.js or on form level using columns.

<FileElement :inline="true" ... />

Renders the element and all of its components in a single <span> without applying columns.

<FileElement size="sm" ... />
<FileElement ... /> <!-- Default size: 'md' -->
<FileElement size="lg" ... />

The size of the element and its child components.

<FileElement view="alt" ... />

The name of the view to be used for the element and by default for its child components. If undefined the default view will be used. Child component views can be overridden with views option.
