MongoGridFS::storeUpload — Stores an uploaded file in the database
name
The name of the uploaded file 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 index will be populated with the filename used.
Returns the _id of the saved file document. This will be a generated MongoId unless an _id was explicitly specified in the extra parameter.
| 版本 | 说明 |
|---|---|
| 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. |
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']));
?>
