[英]pass array values from javascript to php
<script>
$("#submit").click(function () {
var newhour= [];
for (var i = 0; i < arrayNumbers.length; i++) {
newhour.push(arrayNumbers[i].toString().split(','));
console.log("each: " + newhour[i]); // output: each: 07:00,08:30
each: 18:00,19:00
}
console.log("all: " + newhour); //output: all: 07:00,08:30,18:00,19:00
var jsonString = JSON.stringify(newhour);
$.ajax({
type: "POST",
url: "exp.php",
data:{data: jsonString},
cache: false,
success: function(){
alert("OK");
}
});
});
<script>
I want to pass the newhour array values to php and use them to insert into a table. 我想将newhour数组值传递给php,并使用它们插入表中。 so php file, exp.php:
因此php文件,exp.php:
$data = explode(",", $_POST['data']);
foreach($data as $d){
echo $d;
$sql = "insert into exp_table (hour) values ('$d')";
mysql_query($sql);
}
However I can not take the values. 但是我不能接受这些值。 What is wrong with the code?
代码有什么问题? Could you please help me?
请你帮助我好吗? Thanks in advance.
提前致谢。
according to the answers i tried this on php side, but it returns NULL. 根据我在php端尝试过的答案,但是它返回NULL。
$data = json_decode($_POST['data'],true);
//$data = explode(",", $_POST['data']);
echo "data: " .$data;
var_dump($data); // no output
foreach($data as $d){
echo $d; // no output
}
Pass the array without JSON.stringify
in ajax data post. 在ajax数据发布中传递不带
JSON.stringify
的数组。 And fetch the data in php file using $_POST['data']
. 然后使用
$_POST['data']
获取php文件中$_POST['data']
。
I just have tried below code and it working great. 我只是尝试下面的代码,它的工作很棒。
<?php
if(isset($_POST['data'])){
print_r($_POST);exit;
}
?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
var newhour= [];
arrayNumbers = [['07:00','08:30'],['08:30','18:00','19:00']];
for (var i = 0; i < arrayNumbers.length; i++) {
newhour.push(arrayNumbers[i].toString().split(','));
console.log("each: " + newhour[i]);
// output: each: 07:00,08:30 each: 18:00,19:00
}
console.log("all: " + newhour); //output: all: 07:00,08:30,18:00,19:00
$.ajax({
type: "POST",
url: "abc.php",
data:{data: newhour},
cache: false,
success: function(data){
console.log(data);
}
});
});
</script>
You do not have to stringify an array in the javascript. 您不必在javascript中对数组进行字符串化。
.ajax looks after all that. .ajax负责所有这些工作。
pass 通过
data: {newhours: newhour},
then you will get $_POST['newhours']
in the PHP code which will be the array you had in javascript. 那么您将在PHP代码中获得
$_POST['newhours']
,这将是您在javascript中拥有的数组。
In Ajax there is not "type" params, use "method". 在Ajax中没有“类型”参数,请使用“方法”。 Beside that everything should works, you might need to decode the json using
json_decode($_POST['data'])
on in your php file. 除了一切正常之外,您可能还需要在php文件中使用
json_decode($_POST['data'])
解码json。
Hopes it helps ! 希望能有所帮助!
