我试图在wordpress中以表单形式输入插入数据，并希望使用ajax来实现这一点。如果没有ajax，它工作得很好，但当我使用ajax时，按submit按钮得到的结果为0，数据不会插入到数据库中。下面是我的代码。

Html代码位于表单标记之间，如下所示

<form id="insertform" action="" method="post">
<input id="user" style="height: 30px;" name="user" type="text" />
.
.
.
<button id="Submit" type="submit">SUBMIT </button>
</form>

function wp_insert(){
if(isset($_POST[\'skillname\'])!= \'\' && $_POST[\'Address\']!= \'\'){
    $user_info = wp_get_current_user();
$username=$user_info->user_login;
//insert to database

If($_POST[\'Submit\']) {

// run validation if you\'re not doing it in js
global $wpdb;

//assigning textbox values to variables

$yourname=$_POST[\'user\'];
$lat=$_POST[\'latitude\'];
$long=$_POST[\'longitude\'];
$address=$_POST[\'Address\'];
$city=$_POST[\'City\'];
$state=$_POST[\'State\'];
$country=$_POST[\'Country\'];
$zip=$_POST[\'zipcode\'];
$skillname=$_POST[\'skillname\'];
$yourself=$_POST[\'yourself\'];
$email=$_POST[\'email\'];
$phone=$_POST[\'phone\'];


if($wpdb->insert(
        \'wp_store_locator\',
        array(
                \'secretcode\' =>$username,
                \'sl_description\' => $yourname,
                \'sl_latitude\' => $lat,
                \'sl_longitude\' => $long,
                \'sl_address\' => $address,
                \'sl_city\' => $city,
                \'sl_state\' => $state,
                \'sl_country\' => $country,
                \'sl_zip\' => $zip,
                \'sl_store\' => $skillname,
                \'yourself\' => $yourself,
                \'sl_email\' => $email,
                \'sl_phone\' => $phone )) == false) wp_die(\'Database Insertion failed\'); else echo \'Database insertion successful\'; exit();

}

}

}//end of function

add_action( \'init\', \'add_insert\' ); 

function add_insert(){  

add_action( \'wp_ajax_wp_insert\', \'wp_insert\' );
add_action( \'wp_ajax_nopriv_wp_insert\', \'wp_insert\');
// register & enqueue a javascript file called globals.js
wp_register_script( \'globalss\', get_stylesheet_directory_uri() . "/js/ajaxinsert.js", array( \'jquery\' ) ); 
wp_enqueue_script( \'globalss\' );

// use wp_localize_script to pass PHP variables into javascript
wp_localize_script( \'globalss\', \'yess\', array( \'ajaxurl\' => admin_url( \'admin-ajax.php\' ) ) );
}  

jQuery(function ($) {
    $("#insertform").submit(function (e) { //form is intercepted
        e.preventDefault();

        //serialize the form which contains secretcode
        var sentdataa = $(this).serializeArray();

        //Add the additional param to the data        
        sentdataa.push({
            name: \'action\',
            value: \'wp_insert\'
        })

        //set sentdata as the data to be sent
        $.post(yess.ajaxurl, sentdataa, function (rez) { //start of funciton
            alert(rez);

            return false;
        } //end of function
        ,
        \'html\'); //set the dataType as json, so you will get the parsed data in the callback
    }); // submit end here
});
