我想做一个陷阱,如果数组在数据库中的值相同。然后他们将进入我构建的if条件。到目前为止,这是我的代码。
$a = $_POST['a'];
$b = $_POST['b'];
foreach ($_POST['b'] as $b)
{
$result = mysql_query("select * from ehr_schedule3 where (sched3_time='$b' and sched2_id='$a') ");
$row = mysql_fetch_array($result);
$num = mysql_num_rows($result);
}
if(strpos($b, $result)==true) //$b is the array value I will insert to the db.
{
header("Location: ../edit_sched2.php?asdfghjkl=".$a."?false");
$_SESSION["A"] = "E" ;
}
我不知道如何在mysql_query中使用数组。如果只有一个相同的值,我只想继续if
。我最初计划将其设为字符串,以便strpos
确认它具有相同的值,然后它将继续进入if

我想有一天你可以在查询中使用DISTINCT
子句,这样你就不会得到重复项。顺便说一句,您应该使用mysqli
,因为不推荐使用mysql_functions。我想评论澄清,所以我可以帮助你更多,但我还没有50个声誉。所以对于我的理解到目前为止,这就是我要做的事情:
$a = $_POST['a'];
$b = $_POST['b'];
$query = "SELECT schedule3_time, schedule2 FROM ehr_schedule3 WHERE sched3_time LIKE $a and sched2_time LIKE $b "
$key = mysqli_connect($host, $user, $passwd, $database)
or die(mysql_error); /*your credientials */
foreach ($_POST['b'] as $b)
{
$result = mysqli_query($key, $query);
$row = mysqli_fetch_array($result);
$num = mysqli_num_rows($result);
}
if(strpos($b, $result)==true) {
$sql = "INSERT INTO tablename (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com')"; /* put your table here*/
if (mysqli_query($key, $query)) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$key->close();
} //$b is the array value I will insert to the db.
{
header("Location: ../edit_sched2.php?asdfghjkl=".$a."?false");
$_SESSION["A"] = "E" ;
}
