Dynamically create associative array.

[ttmt_101]

Hi all

 

I'm using Wordpress, I have three simple pages with the titles - Page One, Page Two, Page Three

 

Each page has a tag of 'content'.

 

For each page I would like to create an array with a name the same as that page so Page_One[], Page_Two[] etc.

 

I would like to then add and retrieve vales from this array.

 

In the example here the is_Array echo says it's and array.

 

The print_r and count show the array is empty.

 

Is it possible to create an associative array and name it dynamically here, then add and retrieve values.

 

<?php

	$mt_test_args = array(

		'post_type' => 'page',

		'tag' => 'font',

		'order' => 'ASC'

	);


	$mt_test_loop = new WP_Query($mt_test_args);


	if($mt_test_loop->have_posts()):

		while($mt_test_loop->have_posts()):

			$mt_test_loop->the_post();


	$weight = get_post_meta($post->ID,'weight',false);		


	// create array for each font		

	$arr_name = get_the_title();

	$arr_name = str_replace(' ','_',$arr_name);

	${$arr_name} = array();// The font array


	echo is_Array($$arr_name) ? 'yes' : 'no';


	// Add text and font size keys to array

	$$arr_name[$text] = 'first text';

	$$arr_name[$font_size] = '2';


?>	


<option><?php the_title(); ?></option>


<?php endwhile; endif; ?>


<?php wp_reset_postdata(); ?>


<?php 

	print_r($Alber_New);

	echo count($Alber_New);

	echo $Alber_New[$text];

?>

You're using arrays so why use dynamic variables?  Also, I don't see where you define $text and $font_size.

$title = str_replace(' ','_',get_the_title());
//$pages[$title][$text] = 'first text';
//$pages[$title][$font_size] = '2';

// I think you meant:
$pages[$title]['text'] = 'first text';
$pages[$title]['font_size'] = '2';

And really, since you're using the title as an array key you don't need the str_replace().

Sorry, $text and $font_size is a typo, text and font_size were just examples of content i might add to the array, I'm not apply to edit the original post now.

 

I want to use dynamic variables so I can l reference the arrays later in my code. If there are 3 pages and 3 arrays are created how do I reference the correct array.

 

I used str_replace() because the page titles have spaces and I didn't think i could have space in an array name.
