保存通过Ajax返回的信息后出现$ _POST错误 [英] $_POST error after saving information that was returned via Ajax

问题描述

遇到PHP $ _POST问题。然后我保存信息并检查$ _POST ['g_kcal'];返回

 注意：未定义的索引：
中的g_kcal  

输入变化后，此字段的g_kcal计数的所有输入字段值。它通过ajax返回名称为'g_kcal'的新输入。

JavaScript：

  $（'。box-body'）。change（function（）{
 var totalPointsKcal = 0; 
 $ b $（this）.find（'input [name = kcal []]'）。each（function（i，n）{
 totalPointsKcal + = parseFloat（$（n）.val（），10）; 
}）; 
 
 $ .ajax（{
 type：'post'，
 url：'ajaxLoader.php'，
 data：{
 galutinis_kcal：totalPointsKcal，
} ，
 success：function（response）{
 document.getElementById（galutinis）。innerHTML = response; 
} 
}）; 
}）; b 
 
 
 $ b ajaxLoader.php： >  if（isset（$ _ POST ['galutinis_kcal']））{
 $ kcal = $ _POST ['galutinis_kcal']; 
 
 echo< input class ='skaiciuokle kcal1'type ='text'name ='g_kcal'value =。 （$ kcal，1）。disabled>; 
} 
  

找不到它们的问题是。也许POST无法接收通过ajax发送的信息？

解决方案

问题是输入字段被设置为DISABLE。现在它工作正常

Have issue with PHP $_POST. Then I save information and check $_POST['g_kcal']; returned

Notice: Undefined index: g_kcal in

This field g_kcal count's all input fields values after input change. It returns new input with name = 'g_kcal' via ajax.

JavaScript:

$('.box-body').change(function(){
    var totalPointsKcal = 0;

    $(this).find('input[name="kcal[]"]').each(function(i,n){
        totalPointsKcal += parseFloat($(n).val(),10); 
    });

    $.ajax({
        type: 'post',
        url: 'ajaxLoader.php',
        data: {
            galutinis_kcal:totalPointsKcal,
        },
        success: function (response) {
            document.getElementById("galutinis").innerHTML=response;
        }
    });
});

ajaxLoader.php:

if(isset($_POST['galutinis_kcal'])) {
    $kcal = $_POST['galutinis_kcal'];

    echo "<input class='skaiciuokle kcal1' type='text' name='g_kcal' value=". round($kcal, 1) ." disabled>";
} 

Can't find their the problem is. Maybe POST can't receive information that was send via ajax ?

解决方案

The problem was input field was set to DISABLE. Now it's working fine
