我有这个功能:它正常工作,
function ms_get_did_detail($id) {
global $link;
$q2="select Dest,Priority from destpr where Id='$id'";
if($res2=mssql_query($q2)) {
while($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC)) {
return $row2;
}
return 0;
}
return 0;
}
我希望将每个元素(每个Dest& Priority)插入到MYSQL中
if($info=ms_get_did_detail($value)) {
print_r($info);
$destination = $info['Dest'];
$priority = $info['Priority'];
my_did_destination ($priority , $dest , $active , $did_voip , $cc_id);
}
它返回如下数组:
[0]=> Array (
[Dest] => 100
[Priority] => 1
)
[1]=> Array (
[Dest] => 200
[Priority] => 3
)
[2] => (
)
另外,我有这个函数在数据库中插入值:
function my_did_destination($priority="",$destination="") {
global $link_voip;
$sql="INSERT INTO cc_did_destination (destination,priority)
VALUES ('$destination','$priority')";
$retval = mysql_query( $sql , $link_voip);
if(! $retval ) {
die('Could not enter data: ' . mysql_error());
}
}
但它在
中插入空值答案 0 :(得分:1)
您正在插入ID为0
的所有行,因此,如果已存在id=0
的行,则会失败并且不会插入。
也许最简单的解决方案是使用以下SQL语句创建ID
列autoincrement
:
ALTER TABLE cc_did_destination
MODIFY COLUMN id INT auto_increment;
然后更改您的INSERT
声明:
$sql="INSERT INTO cc_did_destination (destination,priority)
VALUES ('$destination','$priority')";

您的$ info是行数组,它有数字键,而不是' Dest'。
您应该添加索引,例如$dest = $info[0]['Dest']
。
if($info=ms_get_did_detail($value))
{
print_r($info);
$dest = $info[0]['Dest'];
$priority = $info[0]['Priority'];
my_did_destination ($priority , $dest , $active , $did_voip , $cc_id);
}
或者您可以使用循环遍历$info
:
if($info=ms_get_did_detail($value))
{
foreach($info as $row) {
$dest = $row['Dest'];
$priority = $row['Priority'];
my_did_destination ($priority , $dest);
}
}
另外,从插入语句中删除id
答案 2 :(得分:0)
这里有几个问题。
首先,您的第一个函数返回一个数组数组。即,它返回第一行的下标为0的数组(它只返回一行详细信息),这是一个包含行详细信息的数组。
您将此分配给$ info变量,因此它包含: -
[0]=> Array (
[Dest] => 100
[Priority] => 1
)
然后您将$ info ['Dest']分配给$ destination,将$ info ['Priority']分配给$ priority。然而,这些都不存在。你需要$ info [0] ['Dest']和$ info [0] ['Priority']。
第二个问题是您尝试将特定值分配给自动增量ID字段。只需将其从插入中删除,或将其赋值为null。
快速重写,我建议你需要这样的东西: -
<?php
if($info=ms_get_did_detail($value))
{
print_r($info);
foreach($info AS $info_row)
{
$destination = $info_row['Dest'];
$priority = $info_row['Priority'];
my_did_destination ($priority , $dest , $active , $did_voip , $cc_id);
}
}
function ms_get_did_detail($id)
{
global $link;
$q2="select Dest,Priority from destpr where Id='$id'";
if($res2=mssql_query($q2))
{
if ($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC))
{
while ($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC))
{
}
return $row2;
}
else
{
return 0;
}
}
return 0;
}
function my_did_destination($priority="",$destination="")
{
global $link_voip;
$priority = mysql_real_escape_string($priority);
$destination = mysql_real_escape_string($destination);
$sql="INSERT INTO cc_did_destination (id,destination,priority) VALUES (NULL,'$destination','$priority')";
$retval = mysql_query( $sql , $link_voip);
if(! $retval )
{
die('Could not enter data: ' . mysql_error());
}
}
编辑
如果您想避免不必要的多次插入,那么使用对象可能会更容易。这样,当有足够的批次时,你可以轻松地进行插入(我通常一次做255次)。
这样的东西,虽然你可能应该使用mysqli _ *
<?php
if($info=ms_get_did_detail($value))
{
print_r($info);
$insert_object = new insert_details($link_voip);
foreach($info AS $info_row)
{
$insert_object->set_row($info_row['Priority'], $info_row['Dest']);
}
unset($insert_object);
}
function ms_get_did_detail($id)
{
global $link;
$q2="select Dest,Priority from destpr where Id='$id'";
if($res2=mssql_query($q2))
{
if ($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC))
{
while ($row2[]=mssql_fetch_array($res2,MSSQL_ASSOC))
{
}
return $row2;
}
else
{
return 0;
}
}
return 0;
}
class insert_details()
{
private $db;
private $insert_row = array();
public function __CONSTRUCT($db)
{
$this->db = $db;
}
public function __DESTRUCT()
{
$this->do_insert();
}
public function set_row($priority="",$destination="")
{
$priority = mysql_real_escape_string($priority, $this->db);
$destination = mysql_real_escape_string($destination, $this->db);
$this->insert_row[] = "(NULL,'$destination','$priority')";
if (count($this->insert_row) > 255)
{
$this->do_insert();
}
}
private function do_insert()
{
$sql="INSERT INTO cc_did_destination (id,destination,priority) VALUES ".implode(',', $this->insert_row);
$retval = mysql_query($sql, $this->db);
if(! $retval )
{
die('Could not enter data: ' . mysql_error());
}
$this->insert_row = array();
}
}
快速粗略mysqli_ *等效,假设 $ link_voip 是一个mysqli连接。请注意,带有绑定参数的预处理语句是一个选项(并且它会使忘记转义变量变得更加困难),但是当您执行多个这样的插入时,它会变得有点混乱。
<?php
if($info=ms_get_did_detail($value))
{
print_r($info);
$insert_object = new insert_details($link_voip);
foreach($info AS $info_row)
{
$insert_object->set_row($info_row['Priority'], $info_row['Dest']);
}
unset($insert_object);
}
function ms_get_did_detail($id)
{
global $link;
$q2="select Dest,Priority from destpr where Id='$id'";
if($res2=mssql_query($q2))
{
if ($row2[]=mssql_fetch_array($res2, MSSQL_ASSOC))
{
while ($row2[]=mssql_fetch_array($res2, MSSQL_ASSOC))
{
}
return $row2;
}
else
{
return 0;
}
}
return 0;
}
class insert_details()
{
private $db;
private $insert_row = array();
public function __CONSTRUCT($db)
{
$this->db = $db;
}
public function __DESTRUCT()
{
$this->do_insert();
}
public function set_row($priority="",$destination="")
{
$priority = mysqli_real_escape_string($this->db, $priority);
$destination = mysqli_real_escape_string($this->db, $destination);
$this->insert_row[] = "(NULL,'$destination','$priority')";
if (count($this->insert_row) > 255)
{
$this->do_insert();
}
}
private function do_insert()
{
$sql="INSERT INTO cc_did_destination (id,destination,priority) VALUES ".implode(',', $this->insert_row);
$retval = mysqli_query($this->db, $sql);
if(! $retval )
{
die('Could not enter data: ' . mysqli_sqlstate($this->db));
}
$this->insert_row = array();
}
}
答案 3 :(得分:0)
你的数组是:
[0]=> Array (
[Dest] => 100
[Priority] => 1
)
[1]=> Array (
[Dest] => 200
[Priority] => 3
)
[2] => (
)
所以它是一个多维数组。如果您需要插入所有这些条目,则不应为同一事件运行多个查询。只需使用mysql批量插入语法。 (例如INSERT INTO tbl (col1,col2,col3) VALUES(a,b,c),(d,e,f),(g,h,i)
)
为insert创建查询字符串。
foreach($a as $i => $v)
{
$b[] = '("'.$v['Dest'].'","'.$v['Priority'].'")';
}
$c = implode(',', $b);
$sql = "INSERT INTO cc_did_destination (destination,priority)
VALUES ".$c;
然后运行查询
N.B。
Please, don't use mysql_*
functions in new code。它们不再被维护and are officially deprecated。请参阅red box?转而了解prepared statements,并使用PDO或MySQLi - this article将帮助您确定哪个。如果您选择PDO here is a good tutorial。
