多維數組-foreach,在foreach中

[英]Multidimensional Array - foreach, within a foreach

我有一個多維數組,可以准確地打印出我想要的樣子,但是,我一直在努力弄清楚如何將其構造到要查找的每個循環中。

請注意 :$ handle是客戶端在后端輸入的字段。

<?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
    )
);
?>

現在,我希望將其作為無序列表吐出來,這樣我可以看到下面的內容,但是它仍然對我不起作用。

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

我想要這樣,以便它遍歷所有社交平台並實現類似的功能

<li><a href="<?php echo ($url);?><?php echo ($handle);?>" class="<?php echo ($class); ?>"><?php echo $name; ?></a></li>

或更好地了解

<li><a href="http://www.facebook.com/handle" class="facebook">Facebook</a></li>

另外,如果我為自己准備的內容變得過於復雜,請告訴我。

<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; ?></a></li>
    <?php endforeach; ?>
</ul>

我認為,如果我已正確理解,這就是您要尋找的東西。

<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>

不需要內在地進行學習。

<?php foreach ($social_array as $name => $group) :?>
        <li><a href="<?php echo $group['url'] ?>" class="<?php echo $group['class'] ?>"><?php echo $group['class']; ?></a></li>
<?php endforeach; ?>

有關以下示例,請參見http://3v4l.org/3cH6f 只是一個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><a href="' . $class_array['url'] . $class_array['handle']  .'" class="' . $class_array['class']. '">'. $name. '</a></li>';
}
$html .= '</ul>';

print $html;
?>

試一下:

<ul>
    <?php foreach ($social_array as $name => $properties) :?>
        <li><a href="<?php echo ($properties["url"] . $properties["handle"]); ?>" class="<?php echo ($properties["class"]); ?>"><?php echo ucfirst($name); ?></a></li>
    <?php endforeach; ?>
</ul>

在此foreach中,語法為foreach($array as $key => $value) ,因此這里$name是$ social_array中的鍵,而$properties是與該鍵關聯的數組。

您忘記的是內部的foreach正在處理每個項目,即class,ulr,handle一個。

因此,當您遍歷這3個項目時,您需要存儲所需的信息,以便在您實際擁有2個項目時就可以使用該信息。

因此,這可能會有所幫助。

<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><a href="' . $url.$handle . '" class="' . $class . '">' . $group . '</a></li>';

               $class   = NULL;
               $url     = NULL;
               $handle  = NULL;
            endif;

        endforeach;

    endforeach;
?>
</ul>
