在wordpress中，我创建了一个插件，它有以下文件
统计访问者
<?php
/*
Plugin Name: Wp Visitor Statistics
Plugin URI:
Description: Statistics about Visitors
Author:
Version: 1.0.1
Author URI:
*/
ob_start();
define('STATISTICS_FOLDER', dirname(plugin_basename(__FILE__)));
//CREATING MENU PAGES IN SIDEBAR
add_action('admin_menu','statistics_admin_menu');
function statistics_admin_menu() {
$icon_url=get_option('siteurl').'/wp-content/plugins/'.STATISTICS_FOLDER."/lea.png";
add_menu_page("Statistics","Statistics",10,__FILE__,"Settings",$icon_url);
add_submenu_page(__FILE__,"Stat Report","Statistics Report",10,"visitor_stat/statreport.php");
}
function Settings()
{
$plugindir = get_option('siteurl').'/wp-content/plugins/'.STATISTICS_FOLDER.'/';
echo "<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js'/></script>'n";
echo "<br/>";
echo "<script type='text/javascript' src='$plugindir/calendar/myfuncvisit.js'/></script>'n";
echo "<br/>";
echo "<script type='text/javascript' src='$plugindir/calendar/jquery.datepick.js'/></script>'n";
echo "<br/>";
echo "<link rel='stylesheet' href='$plugindir/calendar/jquery.datepick.css' type='text/css' />'n";
echo "<br/>";
echo "<script type='text/javascript'>
$(function() {
$('#popupDatepicker').datepick({dateFormat: 'yyyy-mm-dd'});
});
</script>";
echo "<br/>";
echo "<div class='wrap'>
<form action='' name='frm1'>
<strong>Todays Visit : <span id='todays_visit'> </span> | Overall Visit :<span id='overall_visit'></span> ( Original Data )<br /></strong><br />
Todays Visit plus : <input type='text' name='todays_visit_plus' id='todays_visit_plus' value=''/><br /><br />
Overall Visit plus : <input type='text' name='overall_visit_plus' id='overall_visit_plus' value=''/><br /><br />
Overall Visit Start Date : <input type='text' class='overall_visit_startdate' id='popupDatepicker'><br /><br />
<div id='msg_save'></div>
<input type='button' name='save' id='save' value='save'/>
</form>
</div>";
}
?>
然后它调用另一个文件js
myfuncvisit.js
// JavaScript Document
$(document).ready(function(){
// loading image displaying function
function loading_show(divid){
$('#'+divid).html("<div class='item' style='padding:45% 0;text-align:center;font-size:11px;color:#666666;'><center><img width='16' height='16' src='loading.gif'><br>Loading</center></div>").fadeIn('swing');
}
// function to show the feed list
function loadData(){
$.ajax
({
type: "POST",
//url: "blog/wp-content/plugins/visitor_stat/stats-operations.php",
url: "/blog/wp-admin/admin.php?page=visitor_stat/stats-operations.php",
data: "type=all",
success: function(msg)
{
alert(msg);
part = msg.split('#');
$("#todays_visit").ajaxComplete(function(event, request, settings)
{
$("#todays_visit").html(part[0]);
});
$("#overall_visit").ajaxComplete(function(event, request, settings)
{
$("#overall_visit").html(part[1]);
});
$("#todays_visit_plus").ajaxComplete(function(event, request, settings)
{
$("#todays_visit_plus").val(part[2]);
});
$("#overall_visit_plus").ajaxComplete(function(event, request, settings)
{
$("#overall_visit_plus").val(part[3]);
});
$("#popupDatepicker").ajaxComplete(function(event, request, settings)
{
$("#popupDatepicker").val(part[4]);
});
}
});
}
function saveData(){
$.ajax
({
type: "POST",
url: "/blog/wp-admin/admin.php?page=visitor_stat/stats-operations.php",
//url: "blog/wp-content/plugins/visitor_stat/stats-operations.php",
data: "type=save&d1="+d1+"&d2="+d2+"&d3="+d3,
success: function(msg)
{
alert(msg);
loadData();
$("#msg_save").ajaxComplete(function(event, request, settings)
{
$("#msg_save").html(msg);
setTimeout('',10000);
$("#msg_save").html(' ').fadeIn('swing');
});
}
});
}
loadData(); // For first time page load default results
$('#save').live('click',function(){
d1=$('#todays_visit_plus').val();
d2=$('#overall_visit_plus').val();
d3=$('#popupDatepicker').val();
saveData(d1,d2,d3);
});
});
但是当我在wordpressadmin中运行该文件时，它显示admin.php的内部服务器错误？page=访问者_stat/stats-operations.php/blog/wp-admin，它不加载ajax页面
我试了好几次，都找不到解决办法。我认为这个问题可能有正确的解决方案。任何人都可以帮我解决这个问题。
很明显，ajax函数URL:POST不起作用。感谢提前解决这个问题
WordPress环境
首先，为了完成这项任务，建议注册一个jQuery脚本，然后将其排入队列，该脚本将把请求推送到服务器。这些操作将挂接在wp_enqueue_scripts操作挂接中。在同一个钩子中，您应该放置用于包含任意Javascript的wp_localize_script。通过这种方式，将在前端提供一个JS对象。这个对象带有jQuery句柄要使用的正确url。
请查看：
- wp_register_script（）；函数
- wp_enque_scripts挂钩
- wp_enque_script（）；函数
- wp_localize_script（）；函数
将这些函数添加到插件文件中。
add_action( 'wp_enqueue_scripts', 'so_enqueue_scripts' );
function so_enqueue_scripts(){
wp_register_script( 'ajaxHandle', get_template_directory_uri() . 'PATH TO YOUR SCRIPT FILE', array(), false, true );
wp_enqueue_script( 'ajaxHandle' );
wp_localize_script( 'ajaxHandle', 'ajax_object', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );
}
文件：jquery.ajax.js
这个文件进行ajax调用。
jQuery(document).ready( function($){
//Some event will trigger the ajax call, you can push whatever data to the server, simply passing it to the "data" object in ajax call
$.ajax({
url: ajax_object.ajaxurl, // this is the object instantiated in wp_localize_script function
type: 'POST',
action: 'myaction' // this is the function in your functions.php that will be triggered
data:{
name: 'John',
age: '38'
},
success: function( data ){
//Do something with the result from server
console.log( data );
}
});
});
最后，在您的插件文件上应该有一个由ajax调用触发的函数。记住后缀：
- wp_ajax（只允许注册用户或管理面板操作使用该函数）
- wp_ajax_nopriv（允许无权限用户使用该函数）
这些后缀加上动作组成了你的动作名称：
wp_ajax_myaction或wp_ajax_nopriv_myaction
add_action( 'wp_ajax_myaction', 'so_wp_ajax_function' );
add_action( 'wp_ajax_nopriv_myaction' 'so_wp_ajax_function' );
function so_wp_ajax_function(){
//DO whatever you want with data posted
//To send back a response you have to echo the result!
echo $_POST['name'];
echo $_POST['age'];
wp_die(); // ajax call must die to avoid trailing 0 in your response
}
希望它能有所帮助！
