使用模块 class 中的 ajax 处理 <select> 值,prestashop 1.6
Handle <select> values with ajax in module class, prestashop 1.6
我正在开发一个 ps 模块,可以让您 class 确定类别中的产品附件并将它们显示在首页产品页面中。
我正在使用带有附件的可拖动列表,当您将它们拖放到类别时,它会变成一个选项标签,每个类别都有一个 select 标签,用于放置附件。
我想保存附件和它们被丢弃的类别,所以我想调用 ajax 将数据带到我的模块 class 但我是新手 ajax 无法接近它。
这是我做的:
js 代码(在正确的 .tpl 内):
<script>
$( ".droptrue" ).droppable({
drop: function( event, ui ) {
//add <option> tag when an attachment is dropped to category's select
$(event.target).append('<option value="' + ui.draggable.attr('id') + '" selected>'+ui.draggable.text()+'</option>');
//remove the <li> wich contained the attachment data
ui.draggable.fadeOut("slow").remove();
var val = $('#categoryAttachmentArr').val();
//var tab = val.split(',');
//for (var i=0; i < tab.length; i++)
//if (tab[i] == $(this).val())
// return false;
//create an array with the next format: 'id_category(1)'-'id_attachment(1)','id_category(2)'-'id_attachment(2)'[....]
//the comma will be the main character that will be splitted
$('#categoryAttachmentArr').val(val + ui.doppable.attr('id') + '-' + ui.draggable.attr('id') +',');
}
});
$('#submitAddProduct').click(function(e){
$.ajax({
type: 'POST',
url: baseDir + 'modules/adjuntos/classes/CategoryAttachment.php',
data: {
ajax: true,
action: \'CategoryArray\',
cat_array: $('#categoryAttachmentArray').val(),
}
dataType: 'json',
success: function(json) {
console.log($('#categoryAttachmentArray').val());
}
});
})
$( ".ui-state-default" ).draggable({
revert: "valid",
});
</script>
还有我的 class:
class CategoryAttachment extends Objectmodel
{
//other functions
public function ajaxProcessCategoryArray()
{
$CategoryAttachmentArr = Tools::getValue('cat_array')
}
}
您无法直接连接到任何 class。您必须使用控制器来执行此操作。
Ajax 发送数据到控制器
控制器使用 class
保存数据
控制器 return 结果到浏览器 (javascript)
终于找到解决办法了,说不定你们中的某个人以后也会遇到这个问题呢。
我在 .tpl 中的代码:
$( ".ui-state-default" ).draggable();
$( ".droptrue" ).droppable({
drop: function( event, ui ) {
//add <option> tag when an attachment is dropped to category's select
$(event.target).append('<option value="' + ui.draggable.attr('id') + '" selected>'+ui.draggable.text()+'</option>');
$('#selectAttachment1').append('<option value="' + ui.draggable.attr('id') + '" selected>'+ui.draggable.text()+'</option>')
//remove the <li> wich contained the attachment data
ui.draggable.fadeOut("slow").remove();
var val = $('#categoryAttachmentArr').val();
//make a serialize() type array
$('#categoryAttachmentArr').val(val + $(this).attr('id') + "=" + ui.draggable.attr('id') +"&");
var value = $('#arrayAttachments').val();
var tab = value.split(',');
for (var i=0; i < tab.length; i++)
if (tab[i] == ui.draggable.attr('id')){
return false;
}
$('#arrayAttachments').val(value+ui.draggable.attr('id')+',');
}
});
$('#submitCategories').click(function(e){
var array = $('#categoryAttachmentArr').val()
$.ajax({
url: '../modules/adjuntos/ajax-call.php',
data: {
action: 'handlearray',
token:new Date().getTime(),
cat: array
},
method: 'POST',
success:function(data){
$('#result').html(data);
}
});
});
ajax 调用转到我的 ajax-call.php 文件:
<?php
//load ps config
require_once(dirname(__FILE__).'../../../config/config.inc.php');
require_once(dirname(__FILE__).'../../../init.php');
require_once('adjuntos.php');
//adjuntos.php is the name of my module main file
if(Tools::getIsset('token') && Tools::getIsset('action'))
{
$mp = new Adjuntos;
echo $mp->handleArray();
}
我的模块主文件中的 handleArray 函数:(它调用我的自定义 class)
public static function handleArray()
{
$html = '';
$array = Tools::getValue('cat');
$arrayExplode = explode("&", $array);
foreach($arrayExplode as $value)
{
$finalArr = explode("=", $value);
if (!CategoryAttachment::postProcess($finalArr))
{
$html .= '<p style="color:red;>Fallo</p>"';
}
}
$html .= '<p style="color:green;>Correcto</p>"';
return $html;
}
我自定义的函数class:
public static function postProcess($finalArr)
{
return Db::getInstance()->execute(
'UPDATE ps_attachment SET id_category = '.$finalArr[0].' WHERE id_attachment = '.$finalArr[1]
);
}//end
这种方式非常有效,并使代码更具可扩展性
