插入部分后有数据未更新。
有一个错误Notice: Undefined variable: domain in C:\wamp64\www\email_verify\index.php on line 69.
Notice: Undefined variable: target in C:\wamp64\www\email_verify\index.php on line 69.
Notice: Undefined variable: target_ip in C:\wamp64\www\email_verify\index.php on line 69.
如果在textarea中输入了3个email，错误会出现3次。
插入第一部分后如何解决并更新数据？
代码在这里:
<?php
include_once('config.php');
if(isset($_POST["email_verify_btn"])) {
$email = $_POST["email_verify"];
if(strpos($email,"\n")) {
$text = explode("\n",$email);
}
function domain_exists($text)
{
$domain = substr(strrchr($text, "@"), 1);
$arr = @dns_get_record($domain, DNS_MX);
if ($arr[0]['host'] == $domain && !empty($arr[0]['target'])) {
return $arr[0]['target'];
}
}
foreach ($text as $abc) {
$status = 1;
$c_by = 1;
$c_date = date('Y-m-d H:i:s');
$c_ip = $_SERVER['REMOTE_ADDR'];
$_SESSION['date_time'] = $c_date;
$insert = $connect->query("INSERT INTO `email_verify_list`(`primary_email`,`session`,`status`,`created_by`, `created_date`, `created_ip`) VALUES ('$abc','".$_SESSION['date_time']."','$status','$c_by','$c_date','$c_ip')");
if($insert == 1) {
$c_by = 1;
$c_date = date('Y-m-d H:i:s');
$c_ip = $_SERVER['REMOTE_ADDR'];
if(filter_var($abc, FILTER_VALIDATE_EMAIL)) {
if(domain_exists($abc)) {
$domain = substr(strrchr($abc, "@"), 1);
$data = @dns_get_record($domain, DNS_MX);
if($data) {
$status = "email id is valid";
}
if (is_array($data) || is_object($data)) {
foreach ($data as $key1) {
$host = $key1['host'];
$target = $key1['target'];
$target_ip = gethostbyname($key1['target']);
}
}
} else {
$status = "mx recored not exist";
}
} else {
$status = "not in syntax" ;
}
$insert_all = $connect->query("UPDATE `email_verify_list` SET `host_name`='$domain',`target`='$target',`target_ip`='$target_ip',`status`='$status' WHERE session='".$_SESSION['date_time']."'");
}
}
}
?>

最佳答案
在您的表中添加自动递增字段，并在插入查询运行后获取最后插入的记录 ID。并将该 ID 用于 where 子句中的更新记录。
