Title: [Plugin: Basic Google Maps Placemarks] Can I use the shortcode on any php without assign it in funct Last modified: August 20, 2016 --- # [Plugin: Basic Google Maps Placemarks] Can I use the shortcode on any php without assign it in funct * Resolved [yzqiang](https://wordpress.org/support/users/yzqiang/) * (@yzqiang) * [13 years, 10 months ago](https://wordpress.org/support/topic/plugin-basic-google-maps-placemarks-can-i-use-the-shortcode-on-any-php-without-assign-it-in-functionphp/) * Hi, I am a old user of your plugin and the translation provider of simplified Chinese. I have used the plugin very well and it gives great help to me and other friends. I am using the plugin in a special circumstance. I want to show one placemark on an URL built by 404.php. I use 404.php because I want to catch the error by building some non-existing but meaningful URL. For example, the URL includes a place like this: [http://www.mywebsite.com/placea/map.htm](http://www.mywebsite.com/placea/map.htm) In 404.php, I want to generate a map when there is map.htm in the URL. But there is no page or post, I can’t specify the page or post name in function.php. I hope you can modify the source code to make the map built by shortcode anywhere without limitation. Is it possible? If it’s not possible, do you think it’s a good idea to use Google Map API directly to build such page? Thanks a lot. * [http://wordpress.org/extend/plugins/basic-google-maps-placemarks/](http://wordpress.org/extend/plugins/basic-google-maps-placemarks/) Viewing 14 replies - 1 through 14 (of 14 total) * Plugin Author [Ian Dunn](https://wordpress.org/support/users/iandunn/) * (@iandunn) * [13 years, 10 months ago](https://wordpress.org/support/topic/plugin-basic-google-maps-placemarks-can-i-use-the-shortcode-on-any-php-without-assign-it-in-functionphp/#post-2913202) * Would something like this work inside 404.php? * ``` if( strpos( $_SERVER[ 'SCRIPT_URL' ], 'map.htm' ) !== false ) { do_shortcode( '[bgmp-map]' ); } ``` * You may have to modify that a bit, but that’s the basic idea. * Thread Starter [yzqiang](https://wordpress.org/support/users/yzqiang/) * (@yzqiang) * [13 years, 10 months ago](https://wordpress.org/support/topic/plugin-basic-google-maps-placemarks-can-i-use-the-shortcode-on-any-php-without-assign-it-in-functionphp/#post-2913241) * Hi, I do the code as follows: 1.In 404.php, I write: 2.In function.php, I write: function my_theme_name_bgmp_shortcode_check(){ add_filter( ‘bgmp_map-shortcode-called’, ‘__return_true’ ); } add_action( ‘wp’,‘ my_theme_name_bgmp_shortcode_check’ ); I trigger the 404 relocation, there’s nothing happened. I check your plugin source code. In core.php line 399, I find such code: if( !$post ) return false; Because 404.php is not a post type, the source code stop and return here. I delete the code, but I find there are so many judgements of post, I decide not to modify your source code and stop the deletion. Can you tell me please why you judge the map must be shown on a post type, not just on a php code. If it’s not important, can you remove all the judgements in your plugin? If you are busy, I think I can help you to do the job. * Plugin Author [Ian Dunn](https://wordpress.org/support/users/iandunn/) * (@iandunn) * [13 years, 10 months ago](https://wordpress.org/support/topic/plugin-basic-google-maps-placemarks-can-i-use-the-shortcode-on-any-php-without-assign-it-in-functionphp/#post-2913247) * The `if( !$post ) return false;` check runs in `mapShortcodeCalled()` and `getMapShortcodeArguments()` because they both interact with the global `$post` object. * `mapShortcodeCalled()` checks to see if the current post uses the shortcode, and if it does, then the JavaScript and CSS files are enqueued. You can move the code to follow the `bgmp_map-shortcode-called` filter, like this: * ``` protected function mapShortcodeCalled() { global $post; $this->mapShortcodeCalled = apply_filters( self::PREFIX .'mapShortcodeCalled', $this->mapShortcodeCalled ); // @todo - deprecated b/c not consistent w/ shortcode naming scheme. need a way to notify people $this->mapShortcodeCalled = apply_filters( self::PREFIX .'map-shortcode-called', $this->mapShortcodeCalled ); if( $this->mapShortcodeCalled ) return true; if( !$post ) return false; ``` * That way you can use the filter to set it from outside the Loop and not have problems with it returning too early because `$post` doesn’t exist. I’ve updated that in the code for the next release. * Since you’re calling the shortcode from a template, the check in `getMapShortcodeArguments()` shouldn’t affect you. * Thread Starter [yzqiang](https://wordpress.org/support/users/yzqiang/) * (@yzqiang) * [13 years, 10 months ago](https://wordpress.org/support/topic/plugin-basic-google-maps-placemarks-can-i-use-the-shortcode-on-any-php-without-assign-it-in-functionphp/#post-2913257) * I have tried your way. But I found the code in the same function: * > protected function mapShortcodeCalled() * There are such codes: * ``` setup_postdata( $post ); $shortcodes = $this->getShortcodes( get_the_content() ); wp_reset_postdata(); ``` * Because get_the_content function works only in the post, and return nothing in 404.php. The map can’t be generated until now.

It’s triggered when no URL can be located. It makes get_the_content function get nothing. I have updated to 1.8.1alpha, but there’s nothing changed I think.

I compare the template do_shortcode model with the post shortcode model carefully. I find in do_shortcode model, the source code down can’t get the shortcode neither. `$this->getShortcodes( get_the_content());` Can you tell me how the plugin can get the shortcode write in the do_shortcode argument? * Thread Starter [yzqiang](https://wordpress.org/support/users/yzqiang/) * (@yzqiang) * [13 years, 10 months ago](https://wordpress.org/support/topic/plugin-basic-google-maps-placemarks-can-i-use-the-shortcode-on-any-php-without-assign-it-in-functionphp/#post-2913283) * Thread Starter [yzqiang](https://wordpress.org/support/users/yzqiang/) * (@yzqiang) * [13 years, 10 months ago](https://wordpress.org/support/topic/plugin-basic-google-maps-placemarks-can-i-use-the-shortcode-on-any-php-without-assign-it-in-functionphp/#post-2913286) * The job has finished. I did 2 jobs. 1.Modify the plugin source code of core. php in 2 positions. First, comment the function getMapShortcodeArguments. * ``` public function getMapShortcodeArguments() { // @todo - this could be made unit testable if post_content was passed in as param, but would need some kind of controller to wrap it. could then return instead of setting $this->mapshortcodeargs directly global $post; //if( !$post ) // return; ``` * Second, move the judtement postion in mapShortcodeCalled function. * ``` protected function mapShortcodeCalled() { global $post; $this->mapShortcodeCalled = apply_filters( self::PREFIX .'mapShortcodeCalled', $this->mapShortcodeCalled ); // @todo - deprecated b/c not consistent w/ shortcode naming scheme. need a way to notify people $this->mapShortcodeCalled = apply_filters( self::PREFIX .'map-shortcode-called', $this->mapShortcodeCalled ); if( $this->mapShortcodeCalled ) return true; if( !$post ) return false; ``` * 2.Add necessary functions in function.php of my theme. * ``` // 地图插件相关 // 打开'bgmp_map-shortcode-called'，让页面加载地图所需js function xiaohafo_bgmp_shortcode_check() { add_filter( 'bgmp_map-shortcode-called', '__return_true' ); } add_action( 'wp', 'xiaohafo_bgmp_shortcode_check' ); // 设置地图参数 function setBGMPMapShortcodeArguments( $options ) { if (strpos($_SERVER["REQUEST_URI"], 'map.html') !== false) { $arr_uri = explode('/', $_SERVER["REQUEST_URI"]); if (is_array($arr_uri)) { $bgmp = lhk_get_post_by_slug($arr_uri[1]); if (is_object($bgmp)) { $options[ 'mapWidth' ] = 725; $options[ 'mapHeight' ] = 600; $options[ 'latitude' ] = get_post_meta($bgmp->ID, 'bgmp_latitude', true); $options[ 'longitude' ] = get_post_meta($bgmp->ID, 'bgmp_longitude', true); $options[ 'zoom' ] = 12; $options[ 'type' ] = 'ROADMAP'; } } } return $options; } add_filter( 'bgmp_map-shortcode-arguments', 'setBGMPMapShortcodeArguments' ); ``` * 3. Show the map in the 404.php. `echo do_shortcode('[bgmp-map"]'); ?>` At last, the map shows on my URL by 404.php, not by post or template file.
