我有一個javascript來創建json數組,它有一個ajax post方法,我必須知道這個json數組應該如何解碼在PHP端?檢索json數組從php json decode
我的JavaScript函數:
var invoices = {invoice: [{ "customerName" : "John" ,"reciptionName" : "Doe" ,"datee" : "2017-09-09" ,"total" : tot }], invoiceLine: []};
for(i=1; i<=count+arr.length-1; i++){
var ss = String(i);
if(arr.includes(ss)){
continue;
}
invoices.invoiceLine.push({
"itemName" : document.getElementById('item'+i).value ,
"qty" : document.getElementById('inputQty'+i).value ,
"value" : document.getElementById('value'+i).value
});
}
$.ajax({
type: "POST",
url: "saveInvoice.php",
data: {json : JSON.stringify(invoices)},
cache: false,
success: function(data) {
alert(data);
location.reload();
}
});
,這是我的PHP:。(它不會將數據保存到數據庫中,我想先發票數據庫中的數據保存現在然後我可以使用invoiveLine數據。另一個表中插入)
$dbhost = "localhost";
$dbuser = "root";
//$dbpass = "dbpassword";
$dbname = "inventory";
$jsonInvoice = json_decode($POST['invoices'],true);
$customerName = $jsonInvoice.["invoice"][0].["customerName"];
$reciptionName = $jsonInvoice.["invoice"][0].["reciptionName"];
$date = $jsonInvoice.["invoice"][0].["datee"];
$total = $jsonInvoice.["invoice"][0].["total"];
mysql_connect($dbhost, $dbuser, '');
mysql_select_db($dbname) or die(mysql_error());
$query = "insert into invoice (customerName,reciptionName,date,total) values ('$customerName','$reciptionName','$date',$total)";
$qry_result = mysql_query($query) or die(mysql_error());
$insertId = mysql_insert_id();
echo $insertId;
是什麼'$ POST [「發票」]'是什麼樣子?另外,'mysql_'構造函數是[**從PHP 5.5開始不推薦使用](https://wiki.php.net/rfc/mysql_deprecation),並且徹底[**在PHP 7 **中被移除](https ://wiki.php.net/rfc/remove_deprecated_functionality_in_php7#extmysql)。請考慮切換到[** MySQLi **](http://php.net/manual/en/book.mysqli.php)或[** PDO **](http://php.net/manual/ en/book.pdo.php),確保您還使用[**參數化查詢**](http://php.net/manual/en/mysqli.quickstart.prepared-statements.php)來防止SQL注入: ) –
首先,不要使用mysql_query,使用mysqli或者PDO並且參數化你的查詢字符串,這樣你就不會受到SQL注入的影響。 – Difster
我更正$ POST到$ _POST,但仍然得到錯誤 –
