ajax调用成功更新记录但不返回echo字符串。此脚本之前正在运行,但可能是因为某些升级它停止工作。它在我的本地系统上工作正常但是当我将它移动到bluehost服务器时它就不起作用了。
这是我的Ajax调用:
// call to ajax script to update site
function autopost_update_site() {
// get base directory url
var baseDir = jQuery('#baseDir').val();
var id = jQuery('#site_id').val();
var site_name = jQuery('#site_name').val();
var site_url = jQuery('#site_url').val();
var is_active;
if ( jQuery('#active_radio').is(':checked') ){
is_active = '1';
} else {
is_active = '0';
}
var username = jQuery('#login_username').val();
var login_pass = jQuery('#login_pass').val();
// call to ajax script to update script
jQuery.ajax( {
type: "POST",
url: baseDir + "/autopost_ajax_actions.php",
data: "id=" + id + "&site_name=" + site_name + "&site_url=" + site_url + "&is_active="+ is_active + "&username=" + username + "&login_pass="+login_pass +"&action=update_site",
beforeSend: function() {
jQuery('#update_site_button').attr("disabled", true);
// shortcode edit button
jQuery('#update_site_button').html('Updating...');
// admin page edit button
jQuery('#update_site_button').val('Updating...');
},
complete: function() {
jQuery('#update_site_button').attr("disabled", false);
// shortcode edit button
jQuery('#update_site_button').html('Update');
// admin page edit button
jQuery('#update_site_button').val('Update');
},
success: function(data) {
alert("Result: " + data); // NOTHING IS HAPPENING HERE, NO ALERT DATA
if (jQuery.trim(data) === "success") {
alert("Site updated.");
// refresh page
window.setTimeout('location.reload()', 200);
} else {
alert("Some error occured, Please try again.");
}
}
});
}
这是我用于ajax操作的自定义php脚本:
// update site
if ( $_POST['action'] == 'update_site' && isset ($_POST['id']) ) {
// collect site data
$site_name = $wpdb->escape($_POST['site_name']);
$site_id = intval($wpdb->escape($_POST['id']));
$site_url = $wpdb->escape($_POST['site_url']);
$username = $wpdb->escape($_POST['username']);
$login_pass = $wpdb->escape($_POST['login_pass']);
$is_active = $wpdb->escape($_POST['is_active']);
$query = $wpdb->prepare("UPDATE " . $autopost_sites_table_name . " SET site_name = %s, site_url = %s, username = %s, login_pass = %s, is_active = %s WHERE id = %s", $site_name, $site_url, $username, $login_pass, $is_active, $site_id);
#$log->LogDebug($query);
// execute query
$result = $wpdb->query($query);
#$log->LogDebug($result);
if ( $result !== FALSE || $result !== 0) {
// return success
$response = "success";
#$log->LogDebug($response);
echo $response; // THIS RESPONSE IS NOT SHOWING ON AJAX SUCCESS
} else {
$log->LogError("Failed to update site with ID: " . $_POST['id']);
echo "Failed to update site.";
}
}
谁能告诉我缺少什么?

按如下方式更改 data
data:{
id:id,
site_name:site_name,
site_url:site_url ,
is_active:is_active ,
username:username,
login_pass:login_pass,
action:"update_site"
}

正如提到的那样,脚本在本地工作得很好但在服务器上没有工作。所以这是一些服务器问题,我在chrome网络中遇到“Access-Control-Allow-Origin”错误。
我刚刚添加了
header('Access-Control-Allow-Origin: *');
到我的ajax动作脚本,它工作了!感谢

后
echo $response;
把
die();
请参阅http://codex.wordpress.org/AJAX_in_Plugins
在示例中它说:
function my_action_callback() {
global $wpdb; // this is how you get access to the database
$whatever = intval( $_POST['whatever'] );
$whatever += 10;
echo $whatever;
die(); // this is required to return a proper result
}
