我有一个 html 文件,它从用户的计算机中选择图像。下面给出了代码
<html>
<body>
<form enctype="multipart/form-data" action="http://localhost/uploader/upload.php" method="POST">
Please choose a photo:
<input name="source" type="file"><br/><br/>
Say something about this photo:
<input name="message" type="text" value=""><br/><br/>
<input type="submit" value="Upload"/><br/>
</form>
</body>
</html>
当我按下上传按钮时,我需要将所选图像的真实路径传递到 upload.php 文件中。upload.php 的代码如下所示
<?php
include_once 'fbmain.php';
//some codes
try{
$uid = $facebook->getUser();
$me = $facebook->api('/me');
$token = $session['access_token'];//here I get the token from the $session array
$album_id = '2179901265385';//MY ALBUM ID
//upload my photo
$FILE_PATH= 'HERE_I_NEED_THE_REAL_PATH_OF_THE_IMAGE';
$facebook->setFileUploadSupport(true);
$args = array('message' => 'Photo Caption');
$args['image'] = '@' . realpath($FILE_PATH);
$data = $facebook->api('/'. $album_id . '/photos?access_token='. $token, 'post', $args);
} catch(FacebookApiException $e){
echo "Error:" .$e;
}
?>
当我为变量提供路径时,$FILE_PATH (eg: $FILE_PATH = 'C:\My Documents\My Pictures\a.jpg')
它工作正常。但我需要从 html 文件选择器中获取此路径。
有没有办法做到这一点?
至少有人能告诉我一种访问文件选择器文本字段值的方法吗?($_POST['texboxname']
在这里不起作用)。
I could find many tutorials which upload images into facebook using graph api but nothing with html file selector
.
那么任何人都可以帮助我吗?
