Question 166571 in Wordpress Question posted in
The official Wordpress documentation can be found here.

Can wordpress post meta info be retrieved based on two known fields?

I’ve given up on programing about 17 years ago, in the times before proper internet in my country. Now I can’t afford a programer so i’ve taken up the task myself, yet my limited coding knowledge seems to have gotten me quite stuck..

Situation:

in wordpress, i have the folowing keys stored in the postmeta table for each post_id: awb_urgent_cargus, _fgo_invoice_link

Problem:

I need to create a shortcode that should display 2 input fields: [$post_id] and [$awb]. If the user enters a matching pair he gets the corresponding invoice link from the same $post_id.

Basicly after submiting,

if the corresponding awb_urgent_cargus key for the input [$post_id] is the value of input [$awb] then return the value for the key _fgo_invoice_link

else, return error

I found some documentation for this but i got stuck writing the code … couldn’t even get the inputs working 🙁
I think that swiching from ms-dos coding in c++ / pascal to the web is quite a bit over my head and while i managed to get around and modify examples for other stuff this one just simpli doesn’t click

get_post_meta( int $post_id, string $key = ”, bool $single = false );

    You could handle input with ajax, wordpress requires you to register allowed actions on backend, perform your check and return the result.

    //js
var value = jQuery.ajax({
                type: 'POST', 
                url: ajaxurl,
                cache: false,
                data:{
                nonce : nonce,
                action: 'FUNCTIONNAME',
                },
                success: function(data, textStatus, jqXHR) {
                    console.log(data.status);
                },
                error: function(jqXHR, textStatus, errorThrown){    
                    console.log('ajax error');
                }
            })

};

        //php    
    add_action('wp_ajax_FUNCTIONNAME', 'FUNCTIONNAME');
                
    function FUNCTIONNAME() {
    //your backend logic here
$data = array();
$data['status'] = 'all good';
echo json_encode($data);
die();
    }

    You can put it all together like this.

    function show_post_meta_value( $args ){

    $atts = shortcode_atts( array(
        'post_id' => '',
    ), $atts, 'show_post_meta_value' );

    if( $post_id != '' ){
        $awb_urgent_cargus = get_post_meta( $post_id, 'awb_urgent_cargus', true );
        $_fgo_invoice_link = get_post_meta( $post_id, '_fgo_invoice_link', true );

        return 'awb_urgent_cargus ==> '. $awb_urgent_cargus.' and _fgo_invoice_link ==> '.$_fgo_invoice_link;
    }

    return '';

}
add_shortcode( 'show_post_meta_value', 'show_post_meta_value' );

    and use like this [show_post_meta_value post_id="yourpostidhere"]
