我在下面有这个代码,它检查文件是否成功上传,失败或取消:
if (success === 1){
result = '<span class="imagemsg'+imagecounter+'">The file was uploaded successfully</span><br/><br/>';
$('.listImage').eq(window.lastUploadImageIndex).append('<div>' + htmlEncode(imagefilename) + '<button type="button" class="deletefileimage" image_file_name="' + imagefilename + '">Remove</button><br/><hr/></div>');
displayInfo = replaceForm;
}
else if (success === 2){
result = '<span class="imagemsg'+imagecounter+'"> The file upload was canceled</span><br/><br/>';
displayInfo = updateForm;
}
else {
result = '<span class="imagemsg'+imagecounter+'">There was an error during file upload</span><br/><br/>';
displayInfo = updateForm;
}
但我有一个JavaScript函数,它在PHP脚本中输出以下内容:
<script language="javascript" type="text/javascript">
window.top.stopImageUpload(<?php echo $result ? 1 : 2; ?>, '<?php echo $_FILES['fileImage']['name'] ?>');
</script>
现在如果文件上传成功,则显示正确的消息,如果取消,则显示正确的消息,但问题是如果文件无法上传,则会在上传消息时显示取消消息而不是错误。我试图改变上面代码的一部分,所以它会是这样的:
...<?php echo $result ? 1 : 2 : 3 ?>..
但这给了我一个错误。我的问题是如何更改上面的代码,以便在文件无法成功上传时能够输出正确的消息?

错误是什么?
您的三元语法不正确:http://davidwalsh.name/php-shorthand-if-else-ternary-operators
正确的语法是:
echo ( <condition> ) ? <event if true> : <event if false>;
