How to add php code to a 'single' page

Howdy,

I am hacking a plugin to fit in with my Atahualpa theme. It requires me to add some PHP code to the 'single posts' page...most other themes have a simple 'single.php' file, however I'm not sure this is the case with Atahualpa is it?

Where abouts would I slot in this PHP code so that it only appears on the single post pages?

in the "center column---> inside the loop" with a conditional statement like

Code:

<?php if is_single() AND "then add the rest of your php code">

Sorry to ask a really basic question....but I don't know how the IF statements work in PHP.

This is the PHP code I want to insert....

PHP Code:


		
			
$post_cats = get_the_categories(); 

$post_coordinates = GeoMashup::post_coordinates(); 

if ( $post_coordinates ) { 

  echo GeoMashup::map( 'map_content=global&map_cat='. $post_cats[0]->cat_ID 

. '&center_lat' . $post_coordinates['lat'] . '&center_lng=' . 

$post_coordinates['lng'] ); 

}

How do I incorporate that into the IF statement you mentioned above?

try this

HTML Code:

<?php if is_single() {

$post_cats = get_the_categories();  

$post_coordinates = GeoMashup::post_coordinates();  

if ( $post_coordinates ) {  

  echo GeoMashup::map( 'map_content=global&map_cat='. $post_cats[0]->cat_ID  

. '&center_lat' . $post_coordinates['lat'] . '&center_lng=' .  

$post_coordinates['lng'] );  

} } ?>

Thanks, I tried pasting the above code at the end of the "The Loop" section in the Centre Column tab of the Athualpa theme options, and the following error came up on the front end.

Parse error: syntax error, unexpected T_STRING, expecting '(' in /home/jake13/public_html/shackn/wp-content/themes/atahualpa/functions.php(389) : eval()'d code on line 22

Any ideas why?

try putting a () around the 'is_single()' so it would be 'if (is_single() )'

Thanks, I tried what you said, and now I get another error :)

Fatal error: Call to undefined function get_the_categories() in /home/jake13/public_html/shackn/wp-content/themes/atahualpa/functions.php(389) : eval()'d code on line 23

well that is from your original code you wanted to insert. That error says that the function 'get_the_categories()' doesn't exist.

Where did you get this code from? if it is a plugin, it should have had that function in it. If you were doing this properly, the code snippet should test to see if the function exists then display a notice on the page to that effect.

But you need to go back and look at the original plugin, you are missing something

Ok, cool, thanks for the advice, I'll speak to the plugin creator and report back with my findings :)
