需要帮助wp_insert_post

Question

这很奇怪

我有这个代码工作，但后来我需要我的数据库中的一些数据，以确保我不再创建相同的帖子标题，因为如果它不唯一我想生成另一个。

我将使用我添加的内容发布代码并使wp_insert_post停止。 但无论我在哪里搜索，我发现人们应该包括他们：

<?php

define( 'SHORTINIT', true );
//local
require_once( $_SERVER['DOCUMENT_ROOT'] . '/wordpress/wp-load.php' );
//live
//require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php' );
global $wpdb;

$subEmail = isset($_POST['subEmail']) ? $_POST['subEmail'] : null;

if($subEmail){

    //Check if $subEmail is in DB
    $dbEmails = $wpdb->get_results( 'SELECT meta_value FROM wp_postmeta WHERE meta_key = "_field_newsletteremail"' );
    foreach($dbEmails as $emailObj){
        if($subEmail === $emailObj->meta_value){
            echo "exists";
            die();
        }
    }
    //else create a coupon for him
    $couponCodeValue = $subEmail.time();
    $couponCodeValue = str_replace(' ', '', $couponCodeValue);
    $couponCodeValue = md5($couponCodeValue);

    //Get Existing Coupons we created
    $dbCoupons = $wpdb->get_results( 'SELECT post_title FROM wp_posts WHERE post_type = "shop_coupon" AND post_status = "publish"' );
    $x = 0;
    $y = 6;
    $couponCodeSixValue = substr($couponCodeValue, $x , $y);

    for($y; $y < strlen($couponCodeValue); $y++){
        //if code found generate new one, else just us the current
        if($dbCoupons[$i]->post_title === $couponCodeSixValue){
            $couponCodeSixValue = substr($couponCodeValue, ($x+1) , ($y+1));
        }
        $x++;
    }

    imagineme_create_coupon($couponCodeSixValue);

}


function imagineme_create_coupon( $couponCodeSixValue ){
    require_once( $_SERVER['DOCUMENT_ROOT'] . '/wordpress/wp-load.php' );        
    $coupon_code = $couponCodeSixValue; // Code
    $amount = '10'; // Amount
    $discount_type = 'fixed_cart'; // Type: fixed_cart, percent, fixed_product, percent_product

    $coupon = array(
        'post_title' => ''.$coupon_code,
        'post_content' => '',
        'post_status' => 'publish',
        'post_author' => 1,
        'post_type'     => 'shop_coupon'
    );

    $new_coupon_id = wp_insert_post( $coupon );

    // Add meta
    update_post_meta( $new_coupon_id, 'discount_type', $discount_type );
    update_post_meta( $new_coupon_id, 'coupon_amount', $amount );
    update_post_meta( $new_coupon_id, 'individual_use', 'yes' );
    update_post_meta( $new_coupon_id, 'product_ids', '' );
    update_post_meta( $new_coupon_id, 'exclude_product_ids', '' );
    update_post_meta( $new_coupon_id, 'usage_limit', '1' );
    update_post_meta( $new_coupon_id, 'expiry_date', '' );
    update_post_meta( $new_coupon_id, 'apply_before_tax', 'yes' );
    update_post_meta( $new_coupon_id, 'free_shipping', 'no' );

    echo $coupon_code;
}

?>

在我添加之前，最底层的功能正在运行：

define( 'SHORTINIT', true );
//local
require_once( $_SERVER['DOCUMENT_ROOT'] . '/wordpress/wp-load.php' );
//live
//require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php' );
global $wpdb;

但如果没有这个，我无法从这边的脚本访问wpdb。

如何确保加载wp_insert_post的所有文件并访问它，因为我收到PHP致命错误：未捕获错误：调用未定义函数wp_insert_post（）
