如何从FormData传递checkbox数组到php

标签: php jquery ajax checkbox form-data

在FormData的情况下,复选框数组无法通过ajax传递给php。以下脚本在没有使用FormData的情况下正常工作。所以我假设问题在于附加在FormData中或从中传递。它返回invalid arguments supplied for foreach()

复选框不是表单元素的一部分,因此

  <input type="checkbox" id="menu" name="menu[]" value="1">
  <input type="checkbox" id="menu" name="menu[]" value="2">
  <input type="checkbox" id="menu" name="menu[]" value="3">

  <form id="form">
  ...........
  </form>

Jquery和ajax

$(document).on('submit', '#form', function(e){
    e.preventDefault();
    var navid = [];
        $("[name='menu[]']:checked").each(function (i) {
        navid[i] = $(this).val();
    });
    if (navid.length === 0){ //tell you if the array is empty
        alert("Please Select atleast one checkbox");
    }
    else {
    var formData = new FormData(this);
    formData.append('navid', navid);
    $.ajax({
        type: 'POST',
        url: 'upload.php',
        data: formData,
        contentType: false,
        cache: false,
        processData:false,
        success: function(data){
            alert(data);
        }
    });
    }
});

PHP

foreach ($_POST["navid"] AS $key => $item){               
    $query1 =$con->prepare("INSERT INTO menu(cid, title, en_title) VALUES (:navid, :menuin, :menueng)");
    $query1->bindParam(':menunin',$_POST["menunin"][$key]);
    $query1->bindParam(':menueng',$_POST["menueng"][$key]);
    $query1->bindParam(':navid',$item);
    $query1->execute();
    echo 'Menu has inserted';     
}

您的PHP代码中有问题:

您正在传递逗号分隔值,因此首先爆炸并使用

$data = explode("," ,$_POST["navid"]);
foreach ($data AS $key => $item){
    $query1 =$con->prepare("INSERT INTO menu(cid, title, en_title) VALUES (:navid, :menuin, :menueng)");
    $query1->bindParam(':menunin',$_POST["menunin"][$key]);
    $query1->bindParam(':menueng',$_POST["menueng"][$key]);
    $query1->bindParam(':navid',$item);
    $query1->execute();
    echo 'Menu has inserted';
}
