我有这个数组来自html表单的数据,我希望将这个数组插入到PHP函数中,该函数处理{mys}的INSERT
查询。
如何将我的数组声明为PDO
if (isset($_POST['submit'])); {
$_POST['name'];
$_POST['age'];
$myarray= array();
foreach ($_POST as $key => $value){
$myarray[$key] = $value;
}
whatever($myarray);
}
functions whatever($myarray) {
$sql=$db->prepare("INSERT INTO `user`(`name`, `age`) VALUES (:name,:age)");
foreach($myarray as $row=>$value){
$sql->bindValue(array($myarray)){
}
$sql->execute();
}
忘记错误的道歉。
这就是我得到的
Warning: PDOStatement::bindValue() expects at least 2 parameters, 1 given in C:\Web\xampp\htdocs\submit.php on line 36

答案 0 :(得分:1)
function pdoSet($fields, &$values, $source = array()) {
$set = '';
$values = array();
if (!$source) $source = &$_POST;
foreach ($fields as $field) {
if (isset($source[$field])) {
$set.="`".str_replace("`","``",$field)."`". "=:$field, ";
$values[$field] = $source[$field];
}
}
return substr($set, 0, -2);
}
此函数将为SET运算符生成正确的序列
`field1`=:field1,`field2`=:field2
插入查询并存储$values
数组中execute()
数组的avtual数据值。
$fields = array('id','name','age','loc'); // allowed fields
$sql = "INSERT INTO `user` SET".pdoSet($fields,$values);
$stm = $dbh->prepare($sql);
$stm->execute($values);
