Multidimensional Array - foreach, within a foreach - php

Question

I have a multi dimensional array that is printing out exactly how I want it, however, I have become stuck on figuring out how I can construct it into the for each loop that i'm looking for.
Please Note : $handle is a field the client entered in the backend.
<?php
$gp = Mage::getStoreConfig('social_code/social_group/google_field');
$ld = Mage::getStoreConfig('social_code/social_group/linkedin_field');
$tw = Mage::getStoreConfig('social_code/social_group/twitter_field');
$fb = Mage::getStoreConfig('social_code/social_group/facebook_field');
$social_array = array(
"facebook" => array(
'class' => "facebook",
'url' => 'https://www.facebook.com/',
'handle' => $fb
),
"twitter" => array(
'class' => "twitter",
'url' => 'https://www.twitter.com/',
'handle' => $tw
),
"linked-in" => array(
'class' => "linked-in",
'url' => 'http://www.linkedin.com/company/',
'handle' => $ld
),
"google-plus" => array(
'class' => "google-plus",
'url' => 'https://plus.google.com/',
'handle' => $gp
)
);
?>
Now i wish to spit this out as an unordered list so i have the below, but its still not working for me.
<ul>
<?php foreach ($social_array as $name => $group) :?>
<?php foreach ($group as $class => $url) :?>
<li><?php echo ("$group"); ?></li>
<?php endforeach; ?>
<?php endforeach; ?>
</ul>
I would like it so that it loops through all the social array and prins something similar to this
<li><?php echo $name; ?></li>
or so understood better
<li>Facebook</li>
Also if I'm making this over complicated for myself please let me know.

Answer 1

<ul>
<?php foreach ($social_array as $name => $group) :?>
<li><?php echo $name; ?></li>
<?php endforeach; ?>
</ul>

Answer 2

I think this is what you're looking for if I've understood correctly.
<ul>
<?php foreach ($social_array as $name => $group) :?>
<li><a href="<?php echo $group['url'].$group[handle']; ?>" class="<?php echo $group['class']; ?>"><?php echo $name
<?php endforeach; ?>
</ul>

Answer 3

There is no need to inner foreach.
<?php foreach ($social_array as $name => $group) :?>
<li><?php echo $group['class']; ?></li>
<?php endforeach; ?>

Answer 4

See http://3v4l.org/3cH6f for the example working below. Just one foreach.
<?php
$social_array = array(
"facebook" => array(
'class' => "facebook",
'url' => 'https://www.facebook.com/',
'handle' => 'Mage::getStoreConfig(\'social_code/social_group/twitter_field\')'
),
"twitter" => array(
'class' => "facebook",
'url' => 'https://www.facebook.com/',
'handle' => 'Mage::getStoreConfig(\'social_code/social_group/twitter_field\')'
),
"linked-in" => array(
'class' => "facebook",
'url' => 'https://www.facebook.com/',
'handle' => 'Mage::getStoreConfig(\'social_code/social_group/twitter_field\')'
),
"google-plus" => array(
'class' => "facebook",
'url' => 'https://www.facebook.com/',
'handle' => 'Mage::getStoreConfig(\'social_code/social_group/twitter_field\')'
)
);
$html = '<ul>';
foreach ($social_array as $name => $class_array){
$html .= '<li>'. $name. '</li>';
}
$html .= '</ul>';
print $html;
?>

Answer 5

Give this a shot:
<ul>
<?php foreach ($social_array as $name => $properties) :?>
<li><?php echo ucfirst($name); ?></li>
<?php endforeach; ?>
</ul>
In this foreach, the syntax is foreach($array as $key => $value), so here $name is the key from $social_array, and $properties is the array associated with that key.

Answer 6

The thing you are forgetting is that the inner foreach is processing each item i.e. class,ulr,handle one at a time.
You therefore need to store the information you require as you pass over each of the 3 items so it can be used once you have the 2 items you actually need.
So this may help.
<ul>
<?php
foreach ($social_array as $name => $group) :
$class = NULL;
$url = NULL;
$handle = NULL;
foreach ($group as $name => $value) :
switch ($name) :
case 'class' : $class = $value; break;
case 'url' : $url = $value; break;
case 'handle' : $handle = $value; break;
endswitch;
if ( isset($class) AND isset($url) AND isset($handle) ) :
echo '<li>' . $group . '</li>';
$class = NULL;
$url = NULL;
$handle = NULL;
endif;
endforeach;
endforeach;
?>
</ul>
