MongoGridFS::storeUpload
(PECL mongo >=0.9.0)
MongoGridFS::storeUpload — Stores an uploaded file in the database
Description
Parameters
-
name -
The name of the uploaded file(s) to store. This should correspond to the file field's name attribute in the HTML form.
-
metadata -
Other metadata fields to include in the file document.
Note:
These fields may also overwrite those that would be created automatically by the driver, as described in the MongoDB core documentation for the » files collection. Some practical use cases for this behavior would be to specify a custom chunkSize or _id for the file.
Note:
The filename field will be populated with the client's filename (e.g. $_FILES['foo']['name']).
Return Values
Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the metadata parameter.
Note:
If multiple files are uploaded using the same field name, this method will not return anything; however, the files themselves will still be processed.
Errors/Exceptions
Throws MongoGridFSException if there is an error reading the uploaded file(s) or inserting into the chunks or files collections.
Changelog
| Version | Description |
|---|---|
| 1.2.5 | Changed second parameter to an array of metadata. Pre-1.2.5, the second parameter was an optional string overriding the filename. |
Examples
Example #1 MongoGridFS::storeUpload() HTML form example
Suppose you have the following HTML form:
<form method="POST" enctype="multipart/form-data">
<label for="username">Username:</label>
<input type="text" name="username" id="username" />
<label for="pic">Please upload a profile picture:</label>
<input type="file" name="pic" id="pic" />
<input type="submit" />
</form>
If you wanted to store the uploaded image in MongoDB, you could do the following in the script handling the form submission:
<?php
$m = new MongoClient();
$gridfs = $m->selectDB('test')->getGridFS();
$gridfs->storeUpload('pic', array('username' => $_POST['username']));
?>
