【问题描述】:
我有一个在 PHP 中工作的简单上传表单(在 Web 中工作),还能够使用 PhoneGap (base64) 从 iPhone 捕获照片并将其显示在设备上。
但我不知道如何使用 PHP 将其上传到我的服务器。
这是在 PHP 中运行的代码:
索引.PHP
<?
//print_r($_POST);
if($_POST["action"] == "Upload Image")
{
unset($imagename);
if(!isset($_FILES) && isset($HTTP_POST_FILES))
$_FILES = $HTTP_POST_FILES;
if(!isset($_FILES['image_file']))
$error["image_file"] = "An image was not found.";
$imagename = basename($_FILES['image_file']['name']);
//echo $imagename;
if(empty($imagename))
$error["imagename"] = "The name of the image was not found.";
if(empty($error))
{
$newimage = "images/" . $imagename;
//echo $newimage;
$result = @move_uploaded_file($_FILES['image_file']['tmp_name'], $newimage);
if(empty($result))
$error["result"] = "There was an error moving the uploaded file.";
}
}
include("upload_form.php");
if(is_array($error))
{
while(list($key, $val) = each($error))
{
echo $val;
echo "<br>\n";
}
}
include("list_images.php");
?>
这里有两个包括...
UPLOAD_FORM.PHP
<form method="POST" enctype="multipart/form-data" name="image_upload_form" action="<?$_SERVER["PHP_SELF"];?>">
<p><input type="file" name="image_file" size="20" value="beautiful.jpg"></p>
<p><input type="submit" value="Upload Image" name="action"></p>
</form>
LIST_IMAGES.PHP
<?
$handle = @opendir("images");
if(!empty($handle))
{
while(false !== ($file = readdir($handle)))
{
if(is_file("images/" . $file))
echo '<img src="images/' . $file . '"><br><br>';
}
}
closedir($handle);
?>
这是在 PhoneGap 中运行在 iPhone 4 (iOS 4.2) 上的代码
INDEX.HTML(在PhoneGap的WWW目录中运行)

};
document.addEventListener("touchmove", preventBehavior, false);
*/
function onBodyLoad()
{
document.addEventListener("deviceready",onDeviceReady,false);
}
/* When this function is called, PhoneGap has been initialized and is ready to roll */
function onDeviceReady()
{
// do your thing!
}
function getPicture(sourceType)
{
var options = { quality: 10 };
if (sourceType != undefined) {
options["sourceType"] = sourceType;
}
// if no sourceType specified, the default is CAMERA
navigator.camera.getPicture(getPicture_Success, null, options);
};
function getPicture_Success(imageData)
{
//alert("getpic success");
document.getElementById("test_img").src = "data:image/jpeg;base64," + imageData;
}
</script>
</head>
<body onload="onBodyLoad()" marginheight=0 marginwidth=0 leftmargin=0 topmargin=0>
<h1>Camera</h1>
<img style="width:80px;height:120px" id="test_img" src="" />
<p>
<!-- for testing, add the buttons below -->
<button onclick="getPicture()">From Camera</button>
<p>
<button onclick="getPicture(PictureSourceType.PHOTO_LIBRARY)">From Photo Library</button>
</body>
</html>
</html>
顺便说一句,虽然我可以从设备相机中获取一张新照片,但我完全无法从库中获取图像...如果有人知道如何做到这一点,我也会很感激那里的反馈。
有没有人能够将照片从 PhoneGap/iPhone 上传到 PHP?非常感谢任何双方的源代码。
【问题讨论】:
-
您正在使用
@错误抑制运算符 lot。请从您的代码中删除所有这些,然后在 PHP 文件的顶部添加以下两个语句:ini_set('display_errors', true); error_reporting(-1);这些步骤将揭示一些可能潜伏的 PHP 错误。 -
Charles,php 代码运行良好。我想不通的是如何访问在移动 safari 上呈现的 base 64 jpg,使用 JavaScript(这是 PhoneGap 使用的)处理它,然后将其上传到运行 php 代码的服务器。有什么想法吗?

唉,我对 iPhone 开发或 PhoneGap 一无所知。如果您只是拍摄图像并将
POSTing 到 PHP 脚本中,我不确定为什么会涉及 base64...
