我试图通过Ajax调用将数据发布到自定义表中，效果很好（在MySQL自定义表中插入了行），但在console.log.

这是我的密码。

PHP

function create_link() {
    global $wpdb;

    if ( check_ajax_referer( \'create_link\', \'nonce\', false ) == false ) {
        wp_send_json_error();
    }

    $table_name = $wpdb->prefix . "custom_table";

    $result = $wpdb->insert( 
        $table_name, 
        array( 
            \'icon\' => sanitize_text_field($_POST[\'icon\']), 
            \'text\' => sanitize_text_field($_POST[\'text\']), 
        )
    );

    if ( $result == false ) {
        wp_send_json_success( \'Link has been created\' );
    } else {
        wp_send_json_error();
    }

    wp_die();

}

add_action( \'wp_ajax_create_link\', \'create_link\' );

( function( $ ) {

    $( document ).ready( function() {

        $( \'.ufb-create\' ).on( \'click\', \'.ufb-btn\', function( event ) {

            var $button = $( this );

            $button.prop(\'disabled\', true);

            var data = {
                \'action\' : \'create_link\',
                \'nonce\'  : $button.data(\'nonce\'),
                \'icon\' : $(\'.icon-input\').val(),
                \'text\' : $(\'.text-input\').val()
            };
        
            $.post(ajaxurl, data )
            .done( function (response) {

                console.log( response );

                if ( response.success == true ) {
                    // display success message
                    $(\'.ufb-create-response\').html( response.data );

                } else {

                    // display error message
                    $( \'.ufb-create-response\' ).html("Something went wrong");
            
                }
                
                // enable button
                $button.prop(\'disabled\', false);
            
            })
            .fail( function(error) {
                console.log(error)
            });
            
        
        } );        

    });

})( jQuery );

{ "success": false }
