Hello Waqas
thanks for your suggestion about get_post_meta(). I think I need to change a bit the code to achieve what I need though.
Here is the code and the logic with an example:
There is a control panel page (ID 118) with 2 buttons: Day and Night.
Once the user press Day, via jquery, we update wpcf-select with the value Day.
Now, navigating the rest of the web site, only content inside [shortcode time="day"] will show. Of course if the user will press Night only content inside the night shortcode will be shown across the web site.
$control_panel_post = 118;
function update_cf() {
global $control_panel_post;
//update this variable via jquery// checkout if types offers an internal function
$update_cf = 'day';
update_post_meta( $control_panel_post, 'wpcf-select', $update_cf);
}
add_action( 'loop_start', 'update_cf' );
function select ($atts,$content) {
global $control_panel_post;
$time = $atts["time"];
$cf = get_post_meta($control_panel_post, 'wpcf-select', true);
if($cf==$time) {
return $content;
}
else {
return null;
}
}
add_shortcode( 'my-shortcode', 'select' );
Now before going to make the code to send the value via jquery is there a method to set it on the frontend like in the backend of the picture attached? Also its not clear to me how Types is working here. I am able to update the custom field only using update_post_meta(118, 'wpcf-select', $update_cf);. The backend menu (in the attached image) is not working even if Im on the same post ID. While on the db I see some entries created automatically.
Ok I coded the jquery part so here is a step by step guide in case someone else could need it.
-- step 1: create a couple HTML buttons
<input type="button" id="day_button" value="Day"/> <input type="button" id="night_button" value="Night"/>
and create a types custom field named "select"
-- step 2: create a myScript.js file into wp-content/uploads/js/
jQuery(document).ready(function ($j) {
$j('#day_button').on('click', function() {
var data = {
action: 'time',
time_var: 'day'
};
$j.post(ajax_var.ajaxurl, data, function(response) {
//reloading in case the shortcode is placed on the same page of the buttons
location.reload();
});
return false;
});
$j('#night_button').on('click', function() {
var data = {
action: 'time',
time_var: 'night'
};
$j.post(ajax_var.ajaxurl, data, function(response) {
location.reload();
});
return false;
});
});
-- step 3: into functions.php
//Place the ID of the page where you want to store the Control Panel custom field
$control_panel_post = 118;
//in case you need to load it dynamically
//$control_panel_post = get_the_ID();
//path to myScript
function JSPath() {
$upload_dir = wp_upload_dir();
$upload_js_dir = $upload_dir['baseurl'] . '/js/';
$FCEdgeJS = $upload_js_dir . 'myScript.js';
return $FCEdgeJS;
}
//localise jquery
function communicate_to_jquery() {
wp_enqueue_script('jquery');
wp_enqueue_script( 'ajaxTime', JSPath() , array('jquery'),'1.0' , true);
wp_localize_script( 'ajaxTime', 'ajax_var', array(
'ajaxurl' => admin_url( 'admin-ajax.php'),
)
);
}
add_action( 'wp_enqueue_scripts', 'communicate_to_jquery' );
//update wpcf-select with jquery
function ajax_time(){
global $control_panel_post;
$update_cf = $_POST['time_var'];
update_post_meta($control_panel_post, 'wpcf-select', $update_cf);
wp_die();
}
add_action( 'wp_ajax_time', 'ajax_time' );
//display the content of the appropriate shortcode
function select ($atts,$content) {
global $control_panel_post;
$time = $atts["time"];
$cf = get_post_meta($control_panel_post, 'wpcf-select', true);
//var_dump ($cf);
if($cf==$time) {
return $content;
}
else {
return null;
}
}
add_shortcode( 'my-shortcode', 'select' );
on the page you have to use this shortcodes
[my-shortcode time="day"]Day Text[/my-shortcode]
[my-shortcode time="night"]Night Text[/my-shortcode]

About Types not updating the custom field from the backend I suspect it is caching the value somewhere, may be there is an option to prevent this? The code is working, but is there a better way to achieve the same result with internal Types api?
Sure take your time.
What about the first question? Is it possible to load Types custom users fields with Views? Using "Data Origin" -> Types Field I do only see custom fields.
