文章数量:1278986

I'm creating a plugin where I have a dashboard that is done with Settings API. I'm trying to save data from that form via AJAX.

Form:

public function agy_dashboard_page() {
    ?>
    <form id="agy-form-submit" action="options.php" method="post">

        <?php
        settings_errors( 'agy_settings_fields' );
        wp_nonce_field( 'agy_dashboard_save', 'agy_form_save_name' ); // CHECK THIS AT THE END
        settings_fields( 'agy_settings_fields' );
        ?>

        <div id="agy-tab1" class="agy-tabcontent">
            <?php do_settings_sections( 'agy_settings_section_tab1' ); ?>
        </div>

        <?php
        submit_button(
            __( 'Save Changes', 'agy' ),
            '',
            'agy_save_changes_btn',
            true,
            array( 'id' => 'agy-save-changes-btn' )
        );

        if ( wp_doing_ajax() ) {
            wp_die();
        }
        ?>

    </form>

    <?php
    if ( ! isset( $_POST['agy_form_save_name'] ) ||
         ! wp_verify_nonce( $_POST['agy_form_save_name'], 'agy_dashboard_save' ) ) {
        return;
    }
    ?>
   
    <?php
}

Register Settings:

public function agy_register_settings() {

    register_setting( 'agy_settings_fields', 'agy_settings_fields', 'agy_sanitize_callback' );

    // Adding sections
    add_settings_section( 'agy_section_id', __( 'General', 'agy' ), array(
        $this,
        'agy_settings_section_callback'
    ), 'agy_settings_section_tab1' );

    // General page fields
    add_settings_field( 'agy_section_id_enabled_disabled', __( 'Enable / Disable', 'agy' ), array(
        $this,
        'agy_section_id_enabled_disabled'
    ), 'agy_settings_section_tab1', 'agy_section_id' );

    add_settings_field( 'agy_section_id_unregister_user', __( 'Show for unregistered users only', 'agy' ), array(
        $this,
        'agy_section_id_unregister_user'
    ), 'agy_settings_section_tab1', 'agy_section_id' );

    add_settings_field( 'agy_section_id_debug_mode', __( 'Activate Debug mode', 'agy' ), array(
        $this,
        'agy_section_id_debug_mode'
    ), 'agy_settings_section_tab1', 'agy_section_id' );
}

AJAX:

function agyAjaxSubmit() {
    var agyFormData = new FormData(this);

    agyFormData.append('agy_save_changes_btn', 1);
    agyFormData.append('security', agy_public_ajax.agy_publisher_name);

    $.ajax({
        type: 'POST',
        url: agy_admin_ajax.ajax_ajaxurl,
        data: agyFormData,
        processData: false,
        contentType: false,
        success: function () {
            console.log('work');
        },
        error: function () {
            console.log('not work');
        }
    });

    return false;
}

$('#agy-form-submit').submit(agyAjaxSubmit);

Without AJAX, it's working fine. But with AJAX, it's not saving any data.

Any help is appreciated.

I just tested your code, I guess the ajaxurl in your javascript is wrong, it must be:

<?php echo admin_url( 'options.php' ); ?>

This is the code I have tested.

class TestAjaxSettingsAPI {
    public function __construct() {
        add_action( 'admin_menu', array( $this, 'agy_admin_menu' ) );
        add_action( 'admin_init', array( $this, 'agy_register_settings') );
    }

    public function agy_admin_menu() {
        add_menu_page( 'Agy menu', 'Agy menu', 'manage_options', 'agy-menu', array( $this, 'agy_dashboard_page' ), '', 99 );
    }

    public function agy_dashboard_page() {
        ?>
        <form id="agy-form-submit" action="options.php" method="post">
    
            <?php
            settings_errors( 'agy_settings_fields' );
            wp_nonce_field( 'agy_dashboard_save', 'agy_form_save_name' ); // CHECK THIS AT THE END
            settings_fields( 'agy_settings_fields' );
            ?>
    
            <div id="agy-tab1" class="agy-tabcontent">
                <?php do_settings_sections( 'agy_settings_section_tab1' ); ?>
            </div>
    
            <?php
            submit_button(
                __( 'Save Changes', 'agy' ),
                '',
                'agy_save_changes_btn',
                true,
                array( 'id' => 'agy-save-changes-btn' )
            );
    
            if ( wp_doing_ajax() ) {
                wp_die();
            }
            ?>
    
        </form>

        <script>
            function agyAjaxSubmit() {
                var agyFormData = new FormData(this);

                agyFormData.append('agy_save_changes_btn', 1);
                // agyFormData.append('security', agy_public_ajax.agy_publisher_name);

                jQuery.ajax({
                    type: 'POST',
                    url: '<?php echo admin_url( 'options.php' ); ?>',
                    data: agyFormData,
                    processData: false,
                    contentType: false,
                    success: function () {
                        console.log('work');

                    }
                });

                return false;
            }

            jQuery('#agy-form-submit').submit(agyAjaxSubmit);
        </script>

        if ( ! isset( $_POST['agy_form_save_name'] ) ||
             ! wp_verify_nonce( $_POST['agy_form_save_name'], 'agy_dashboard_save' ) ) {
            return;
        }
        ?>
       
        <?php
    }

    public function agy_settings_section_callback() {}

    public function agy_section_id_enabled_disabled() {
        // get the value of the setting we've registered with register_setting()
