为什么我的代码中出现以下错误?
致命错误:在....的写入上下文中不能使用函数返回值。
当我第一次开始使用这个函数时,我在if ... else中有返回语句,而错误似乎与return语句有关。但我用echo语句替换它们,我仍然得到错误,所以我不知道发生了什么。有任何帮助或建议吗?
public function wallPostComments() {
// This function processes wall post comments
// pull the submitted comment data
$returnedPostId = $this->inuput->post('entryId');
$returnedCommentData = $this->input->post('returnedCommentData');
// pull the required session data
$userid = $this->session->userdata('userid');
// select the sql data from wallPosts and wallPostComments
$query = $this->db->query("SELECT * FROM wallPosts, wallPostComments");
// loop through the mysql rows and process the expanded sql code
foreach ($query->result() as row()) {
if($row->idwallPosts == $JSONedIdWallPosts) {
echo "success";
} else {
echo "failure";
}
}
}
答案 0 :(得分:3)
row()
何时成为函数?
尝试:
foreach ($query->result() as $row) {
