Access to a variable function from another function in WordPress

Question

there's a problem, I can not understand what I'm doing wrong ..

I want to get the value of the function of the other features in WordPress ..

This code replaces some parts of the code ..

I want to get the value of the argument variable words (it needs to go $attr['words']) and then use the other functions (new_quote).

    <?php
    /*
    * Plugin Name: Random Quotes
    */

    function random_quote($atts) {
        extract( shortcode_atts( array(
        'path' => plugin_dir_path(__FILE__).'quotes.txt',// default, if not set
        'label_new' => 'New Quote',
        'words' => 'no'   // yes or no 
        ), $atts ) );

        $temp = $attr['words']; // no
        ...

    }

    add_shortcode('randomquotes','random_quote');


    function new_quote(){
    global $temp;  // NULL
    /*
    global $attr;
    $temp = $attr['words']; // again NULL
    */
        ...

        if($temp == "no") {
        ...
        }
    }

   ...

?>

What am I doing wrong? Maybe just can not get the value of this variable?

Where are you running this new_quote() function? And why do you need it? — brasofilo

It looks like you need to declare global $temp within your random_quote() function. Right now, random_quote() is using a local version of $temp, which is lost when the function is completed.

EDIT: Here's an example snippet

<?php
function test() {
  global $temp;
  $temp = 'no';
}
function my_test() {
  global $temp;

  var_dump($temp);
}

test();
my_test();
?>

What is returning NULL?

Доктор Скальпинг Over a year ago

When a function is returned, then random_quote argument value (all right), but after the function is called new_quote, it returns NULL. This is an undefined value. But it should not be. I did all the functions of a global variable.

Can you edit your post to show the updates you did to the code to try and get it to work?

Ok, in your random_quote function, add "global $temp;" "above extract( shortcode_atts( array("

Solved the problem this way: simply pass this argument as a parameter query using AJAX. Thanks for the response anyway!
