Force yii2 ajax request to download a file






















Either detail OR detailUrl must be entered. This can be a normal html markup or an anonymous function that returns the markup. This can also be an anonymous function Closure. It is recommended you use the indexBy method on your query that generates the dataProvider to index your grid rows by a unique column value. Only applicable when detailUrl is provided. Defaults to slow.

The following parameters are similar to the DataColumn settings. Default values for these parameters have been carefully set for usage in most scenarios, thus accelerating development. The following jQuery plugin events are available for the expand row column. Each of these events are triggered on the grid element identified by grid's options[id]. The event sends the following parameters for advanced parsing:.

This occurs when you set the detailUrl property in ExpandRowColumn for triggering the ajax call to load expanded content. View this complete web tip on how to setup your model, controller, and view with GridView Editable columns to manipulate records. The model and attribute properties will automatically be derived from the grid column setting. Refer the Editable documentation for all supported options. If the grid's data has a primary key which is numeric or string, then it would be returned as is.

However, if the grid data has a composite primary key array or an object as a key as used in mongo db , then this will return a PHP serialized string, that can be parsed using the PHP unserialize method. The EditableColumnAction offers a quick easy way to setup your controller action for updating, saving and managing the EditableColumn output from GridView. The basic setup of the column involves setting up the controller action and the EditableColumn. In your GridView editable column configuration, include the above controller action for processing the Editable within editableOptions.

For example. If set as a string, it will be returned as is. It allows calculated data for the column, based on values of other columns in the grid just like spreadsheets. The formula calculation is done at grid rendering runtime and does not need to query the database.

Hence you can use formula columns to calculate data from any DataColumn including calculated data from other FormulaColumn except self-referencing itself. You would need to set the following parameters for setting up this column:. If set to true , it will use the same formula to generate the footer.

If set to false , will use the default footer. The following are new features added since release v1. This is different than the visible property, in the sense, xlFormat : string , the cell format for EXCEL exported content.

If the loadEnumAsFilter is set to true , and the filter property is not set, then the filter property will automatically default to this property's value. Defaults to kvradio. The following special option is recognized:. A function may be used to assign different attributes to different rows based on the data in that row. Specifically if you want to set a different value for the radio, you can use this option in the following way in this example using the name attribute of the model :.

This will automatically set the header, body, footer, and page summary to not wrap using the white wrap CSS style. You can listen to the following jQuery events via javascript, to capture the rows selected via the radio column. The following additional properties are available:. The following properties are similar to the DataColumn settings. Users may click on the checkboxes to select rows of the grid.

The selected rows may be obtained by calling the following JavaScript code:. Applicable only if the grid bootstrap property is set to true. Applicable if dropdown is set to true. To align a dropdown at the right edge of the page container, you set this to:. The following additional options are recognized: label : string , the label for the action dropdown button. This is not html encoded. Defaults to Actions.

If null or not set, the default icon with CSS fas fa-eye-open will be displayed as the icon for the default button. If null or not set, the default icon with CSS fas fa-pencil will be displayed as the icon for the default button. If null or not set, the default icon with CSS fas fa-trash will be displayed as the icon for the default button.

Defaults to post. The array keys are the button names without curly brackets , and the values are the corresponding button rendering callbacks. The callbacks should use the following signature:.

Defaults to 0. Defaults to 5. This setting must be greater than or equal to the maxThreads configuration within resumableUploadOptions setting. When set to true , this will override the uploadAsync setting and enable a different upload mode for files to be sent as sliced chunks via AJAX allowing one to also pause and resume uploads. This setting is useful for large file sizes to be sent in parts that can be meaningfully accepted by the server.

The uploadUrl action will be used to parse the file chunks and process the upload to the server. The following properties can be set:. Defaults to the following callback:. This defaults to null.

If not set or false, no test will be performed for the file selected for upload. You can also set this as a function callback which will return a string. The following params are sent to the server for testing the file uploaded. These parameter names can be controlled and set via uploadParamNames. The following params are received back from the server for testing the file uploaded. Based on this the plugin will skip these file chunks and process from the chunks that are missing.

Defaults to KB i. Defaults to 4. This setting must be less than or equal to the maxThreads plugin level setting. Else, the maxThreads plugin level setting will override this property. Defaults to 3. When set to true , files with errors will be skipped and upload will proceed with other files. Defaults to the following setting:. Defaults to null which means no limit on image height. Note that if you set resizeImage property to true , then the entire image will be resized within this height depending on resizePreference.

Defaults to null which means no limit on image width. Note that if you set resizeImage property to true , then the entire image will be resized within this width depending on resizePreference. Note that resizing images requires HTML5 canvas support which is supported on most modern browsers. It is required to be loaded before fileinput. Defaults to width. This property is parsed only when resizeImage is true. If set to width , the maxImageWidth property is first tested and if image size is greater than this, then the image is resized to maxImageWidth.

The image height is resized and adjusted in the same ratio as width. In case, the image width is already less than maxImageWidth then the maxImageHeight property is used to resize and width is adjusted in same ratio. This will behave conversely, when resizePreference is set to height - the maxImageHeight will be first tested against image height and then the rest of steps will be similarly parsed with preference given to height instead of width as before.

This must be a decimal number between 0. Only files beyond a size set here will be resized. The file size must exceed the value set here, else a validation error is thrown using the msgSizeTooSmall setting.

If this is set to null , then the validation is skipped and no minimum value check will be performed. If greater than this, a validation error is thrown using the msgSizeTooLarge setting.

If set to 0 , it means size allowed is unlimited. Files beyond this size will have a default thumbnail without the preview content. If set to 0 or null , it means the preview size allowed is unlimited.

This is to be set carefully for optimal browser memory performance when previewing large files. Defaults to i. If set to 0 , it means number of files are optional. If set to 0 , it means number of files allowed is unlimited. Depending on validateInitialCount property, this value will be validated whether to include initial files in preview. Note that if this is set, the validateInitialCount property will not be used for validating maxFileCount.

Defaults to No. Defaults to No files selected. This is currently applicable only for text file previews. Check the required validation demos for more details on usage of rtl validation. The message is applicable for both the main upload progress bar as well as each individual file thumbnail progress bar.

Defaults to text-danger. Defaults to file-error-message. Defaults to. This is applicable only for the current session and not when the page is refreshed.

This is applicable only for resumable uploads. The keys must be one of deleteThumb , uploadThumb , uploadBatch , or , uploadExtra. Defaults to progress-bar progress-bar-success progress-bar-striped active. Defaults to progress-bar progress-bar-success. Defaults to progress-bar progress-bar-danger.

Defaults to 99 , beyond which the progress bar will display the msgUploadThreshold. Can be one of the following:. Files other than image or text will be displayed as a thumbnail with the filename in the preview window. If not set, will default to the container with CSS class kv-fileinput-error inside the preview container identified by elPreviewContainer. The CSS class as set in msgErrorClass will be automatically appended to this container element when displaying the error markup.

If not set, will default to the container with CSS class file-caption within in the plugin main container. If not set, will default to the container with CSS class file-caption-name inside the main plugin container. If not set, will default to the container with CSS class file-preview inside the main plugin container.

If not set, will default to the container with CSS class file-preview-thumbnails inside the main plugin container. If not set, will default to the container with CSS class file-preview-status inside the main plugin container.
