Nesting foreach in a function

[MadLittleMods]

I think this is the right place to post this but please move if needed as this is my first time on this site.

Okay so I have a multidimensional array that is giving me an error when I put it in a function:

ERROR: Warning: Invalid argument supplied for foreach().. line 123

LINE 123: foreach ( $affiliates as $affiliate )

 

This does work when in one file test2.php which is attached to this post...

 

Here is my whole function:

// affiliate content function start:
function affiliates_content()
{

global $context, $settings, $options, $scripturl, $txt;

foreach ( $affiliates as $affiliate ) 
{

	echo '
		<table>

			<tr>
				<td>
					<a href="',$affiliate[href],'"><img src="',$affiliate[image],'"></a>
				</td>

				<td>
					',$affiliate[title],'
					<br>
					<small><a href="',$affiliate[href],'">',$affiliate[href],'</a></small>
				</td>
			</tr>

		</table>

		<br>


	';

}



}
// affiliate content function end

 

Here is my whole array which is located on another file (subs.php - smf)

// affiliates array for affiliates page
$affiliates = array(
  array(
    "title" => "aff_blah1",
    "image" => "http://aff_blah1.net/images/aff_blah1.png",
    "href" => "http://aff_blah1.net/"
  ),

   array(
    "title" => "aff_blah2",
    "image" => "http://aff_blah2.net/images/aff_blah2.png",
    "href" => "http://aff_blah2.net/"
  ),

   array(
    "title" => "aff_blah3",
    "image" => "http://aff_blah3.net/images/aff_blah3.png",
    "href" => "http://aff_blah3.net/"
  ),
);
// affiliates array end

 

 

Does anyone know how to fix this problem?

$affiliates doesn't exist within your function. Also, all the global's declared are never used, remove them. Using the global keyword completely breaks part of what functions are best at (abstracting away code).

Thanks for moving 

 

Globals removed. nothing...

 

$affiliates does exist and i know the file its on gets called on because the nav bar is also in it and that appears on the page. How do i get it to "see" it?

[trq]

I'm not hinting at the fact that $affiliates doesn't exist, I'm telling you it is fact.

 

You need to pass it to your function.

 

function affiliates_content($affiliates) {
  // rest of code
}

[MadLittleMods]

function affiliates_content($affiliates) {
  // rest of code
}

 

gives me another error:

ERROR: Missing argument 1 for affiliates_content(), called in /*/*/*/*/affiliates/index.php on line 72 and defined in /*/*/*/*/affiliates/index.php on line 118

LINE 72: ',affiliates_content(),'

^ in the another function called just "affiliates"

LINE 118: function affiliates_content($affiliates)

 

Sorry got to go to bed  - Will be checking tommorrow - Thanks for all the help so far!

You then need to pass it to the function when you call it.

 

affiliates_content($affiliates);

 

This is all covered in the manual and should be learned as part of the basics. functions.

[MadLittleMods]

After that the error goes away and I am left with this one again..

 

ERROR: Invalid argument supplied for foreach() in ... line 123

 

Bed time - Thanks for the help so far

Modify your function to this and show us the output.

 

function affiliates_content($affiliates) {
  echo '<pre>';
  print_r($affiliates);
  echo '</pre>';
}

[MadLittleMods]

No output.

 

EDIT:

 

Figured it out! I just had to "pass" the variable to all of the functions that it is nested and called in.

 

Thanks so much for all this great help and moving my thread to the proper position!
