我能够编写这个代码:
<?php
if(isset($_FILES['profile']) === true) {
if (empty($_FILES['profile']['name']) === true) {
echo 'Please choose a file!';
} else {
$allowed = array('jpg', 'jpeg', 'gif', 'png');
$file_name = $_FILES['profile']['name']; //file //line 75
$file_extn = strtolower(end(explode('.' , $file_name))); //line 76
$file_temp = $_FILES['profile']['tmp_name']; // line 77
if (in_array($file_extn, $allowed) === true) {
//upload file
} else {
echo 'incorrect file type. Allowed: ';
echo implode(' , ' , $allowed);
}
}
}
if (empty($user->data()->profile) === FALSE) {
echo '<img src="', $user->data()->profile, '" alt= "', $user->data()->profile, '\'s Profle Image">';
}
?>
然后突然出现错误:
严格的标准:在第76行的C:\ wamp \ www \ coding_exam \ index.php中只能通过引用传递变量
答案 0 :(得分:0)
if (empty($user->data()->profile) === FALSE) {
echo '<img src="', $user->data()->profile, '" alt= "', $user->data()->profile, '\'s Profle Image">';
您无法像这样使用$ user-&gt; data() - &gt;个人资料。这就是问题所在。
