我在GET＆amp;添加了一个if isset命令。 POST语句，有人可以帮助我。我知道在修复此问题后我必须修改我的代码。我的教授提到了使用print-r语句......
感谢您的帮助......我是PHP的新手
答案 0 :(得分：0)
问题在于这句话：
if(isset($_POST['pImage'])) {
$pImage = $_POST['pImage'];
}
由于$_POST['pImage']是图片，因此您无法使用$_POST。要检查是否已上传，只需使用：
if($_FILES['pImage']['name') {
这将检查图像的名称，如果可用，将返回true。
这句话错了：
if ($featured = 1) {echo ' Yes <br />'; } else {echo ' No <br /> ';}
在比较$featured是否等于1时，您需要使用PHP的比较运算符==。 =用于分配。
因此，它应该是：
if ($featured == 1) {echo ' Yes <br />'; } else {echo ' No <br /> ';}
有关PHP运算符的更多信息：http://php.net/manual/en/language.operators.comparison.php。
此外，您不应该禁止错误消息：
@unlink($_FILES['pImage']['tmp_name']);
删除@以启用错误报告。它在诊断语法错误时非常有用。
