Question

我有一个数组make来自某个输入值得到jQuery就像这样

$.ajax({
    url: "update_recipe.php",
    type: "post",
    data: ingredient,
    dataType: "html",
    success : function(code_html, statut){
        console.log(code_html);
        console.log(statut);
    },
    error : function(resultat, statut, erreur){
        console.log("La requête n'a pas aboutie...");
        console.log(resultat);
        console.log(statut);
        console.log(erreur);
    }
    });

并使用像这样的ajax发送

bytes

但是当我需要用php获取数组时，$ _POST为NULL ...
你知道我怎么发送这个数组吗？

感谢

Answer 1

您可以创建一个具有“key = value”对的查询字符串，其中“key”是元素的name属性值，而不是仅将值推送到数组。

var ingredient = "";

text.each(function(i) {
    ingredient += this.name + "=" + this.value + (i < text.length ? "&" : "");
});

var data = $("#form :input").serializeArray();
data = JSON.stringify(data);
post_var = {'action': 'process', 'data': data };
$.ajax({.....etc
