我创建了一个名为set_title()的函数,该函数用于在数据库中设置标题和描述,我不知道我哪里写错了
function set_title($file,$title = "",$description = ""){
$pathinfo = pathinfo($file);
$file = $pathinfo['basename'];
if ($title == "") {
$title = ucfirst($pathinfo['filename']);
}
if ($description !== "") {
$description = mb_substr($description, 0, 150);
}
$sql = "SELECT file, title ,description FROM title WHERE file = '$file'";
$con = new mysqli('localhost','root','','jbstore');
$result = $con->query($sql);
if($result->num_rows > 0){
$data = $result->fetch_assoc();
if($data['description'] == ""){
$sql = "INSERT INTO title (description) VALUES('$description')";
$con->query($sql);
}
}elseif ($result->num_rows == 0) {
$sql = "INSERT INTO title (file,title,description) VALUES ('$file','$title',$description)";
$result = $con->query($sql);
}
}
我希望它可以将数据插入数据库,但是什么也没发生
答案 0 :(得分:0)
代码中的某些问题。
$sql = "INSERT INTO title (file,title,description) VALUES ('$file','$title',$description)";
此处$ description将用作INT值。
在$ description中加上quote('')
$sql = "INSERT INTO title (file,title,description) VALUES ('$file','$title','$description')";
