How can I add the option to upload metadata to the options page?

Question

These are custom metadata image upload options in the general message. I need the same options in add_options_page or add_menu_page. How can I do it?

<?php /** * Adds a meta box to the post editing screen */ function prfx_custom_meta() { add_meta_box( 'prfx_meta', __( 'Meta Box Title', 'prfx-textdomain' ), 'prfx_meta_callback', 'post' ); } add_action( 'add_meta_boxes', 'prfx_custom_meta' ); /** * Outputs the content of the meta box */ function prfx_meta_callback( $post ) { wp_nonce_field( basename( __FILE__ ), 'prfx_nonce' ); $prfx_stored_meta = get_post_meta( $post->ID ); ?> <p> <label for="meta-image" class="prfx-row-title"><?php _e( 'Example File Upload', 'prfx-textdomain' )?></label> <input type="text" name="meta-image" id="meta-image" value="<?php if ( isset ( $prfx_stored_meta['meta-image'] ) ) echo $prfx_stored_meta['meta-image'][0]; ?>" /> <input type="button" id="meta-image-button" class="button" value="<?php _e( 'Choose or Upload an Image', 'prfx-textdomain' )?>" /> </p> <?php } /** * Saves the custom meta input */ function prfx_meta_save( $post_id ) { // Checks save status $is_autosave = wp_is_post_autosave( $post_id ); $is_revision = wp_is_post_revision( $post_id ); $is_valid_nonce = ( isset( $_POST[ 'prfx_nonce' ] ) && wp_verify_nonce( $_POST[ 'prfx_nonce' ], basename( __FILE__ ) ) ) ? 'true' : 'false'; // Exits script depending on save status if ( $is_autosave || $is_revision || !$is_valid_nonce ) { return; } // Checks for input and sanitizes/saves if needed if( isset( $_POST[ 'meta-text' ] ) ) { update_post_meta( $post_id, 'meta-text', sanitize_text_field( $_POST[ 'meta-text' ] ) ); } // Checks for input and saves if needed if( isset( $_POST[ 'meta-image' ] ) ) { update_post_meta( $post_id, 'meta-image', $_POST[ 'meta-image' ] ); } } add_action( 'save_post', 'prfx_meta_save' ); /** * Adds the meta box stylesheet when appropriate */ function prfx_admin_styles(){ global $typenow; if( $typenow == 'post' ) { wp_enqueue_style( 'prfx_meta_box_styles', plugin_dir_url( __FILE__ ) . 'meta-box-styles.css' ); } } add_action( 'admin_print_styles', 'prfx_admin_styles' ); /** * Loads the color picker javascript */ function prfx_color_enqueue() { global $typenow; if( $typenow == 'post' ) { wp_enqueue_style( 'wp-color-picker' ); wp_enqueue_script( 'meta-box-color-js', plugin_dir_url( __FILE__ ) . 'meta-box-color.js', array( 'wp-color-picker' ) ); } } add_action( 'admin_enqueue_scripts', 'prfx_color_enqueue' ); /** * Loads the image management javascript */ function prfx_image_enqueue() { global $typenow; if( $typenow == 'post' ) { wp_enqueue_media(); // Registers and enqueues the required javascript. wp_register_script( 'meta-box-image', plugin_dir_url( __FILE__ ) . 'meta-box-image.js', array( 'jquery' ) ); wp_localize_script( 'meta-box-image', 'meta_image', array( 'title' => __( 'Choose or Upload an Image', 'prfx-textdomain' ), 'button' => __( 'Use this image', 'prfx-textdomain' ), ) ); wp_enqueue_script( 'meta-box-image' ); } } add_action( 'admin_enqueue_scripts', 'prfx_image_enqueue' ); 

I want to set the options page in the "Download" section.

The following is the page code for loading the image:

PHP CODE:

 function your_enqueue_scripts(){ wp_enqueue_script('media-upload'); wp_enqueue_script('thickbox'); wp_enqueue_style('thickbox'); } ?> 

JS CODE:

 jQuery(document).ready(function($){ //upload image $("#upload_image_button").click(function(event) { formfield = jQuery('#your_image').attr('name'); tb_show('', 'media-upload.php?type=image&amp;TB_iframe=true'); return false; }); window.send_to_editor = function(html) { if(formfield) { jQuery('#your_image').replaceWith('<input id="your_image" type="text" name="your_image" value="" style="width:500px" />'); fileurl = jQuery('img','<div>'+html+'</div>').attr('src'); jQuery('#your_image').val(fileurl); jQuery('#your_image_hidden').attr('value',fileurl); } tb_remove(); } }); 

HTML RENDERING:

 if(get_option('your_image')!='') { ?> <img src="<?php echo get_option('your_image');?>" name="your_image" id="your_image" height="100" width="100" /> <input id="bos_logo_hidden" type="hidden" name="your_image" value="<?php echo get_option('your_image');?>" style="width:500px" /> <?php } else { ?> <input id="your_image" type="text" name="your_image" value="" style="width:500px" /> <?php } ?> <br/><br/> <input id="upload_image_id" type="hidden" name="upload_image_id" value="" readonly="readonly" /> <?php if(get_option('your_image')!='') { ?> <input id="upload_image_button" type="button" value="Change Image" class="button-primary " /> <?php } else { ?> <input id="upload_image_button" type="button" value="Upload Image" class="button-primary" /> <?php }
