|
|
Bonjour à tous,
Voici mon tableau de menu:
Code: |
Array (
[0] => Array (
[id] => 1
[children] => 0
[title] => Accueil
[slug] =>
[position] => 1
)
[1] => Array (
[id] => 3
[children] => 2
[title] => Suisse
[slug] => suisse
[position] => 1
)
[2] => Array (
[id] => 2
[children] => 0
[title] => Contact
[slug] => contact
[position] => 99 )
)
|
Mon objectif est le suivant:
Code: | <ul>
<li><a href="" title="#">Accueil</a></li>
<li><a href="contact" title="#">Contact</a>
<ul>
<li><a href="contact-suisse"> suisse</a></li>
</ul>
</li>
</ul>
|
Et voici mon code smarty:
Code: |
<ul>
{function name=menu level=0}
{foreach $data as $element}
<li>{$element.nom}</li>
{if $element.children}
<ul>{menu data=$element.children level=$level+1}</ul>
{/if}
{/foreach}
{/function}
{menu data=$navigations}
</ul> |
Comme retour, j'ai simplement une page blanche, sans code, ni même celui qui est autour du <ul></ul>.
Sauriez-vous m'aider?
Merci à vous ! |

If I were you, I'd change your array to be more like
Code: | Array (
[0] => Array (
[id] => 1
[children] => null
[title] => Accueil
[slug] =>
[position] => 1
)
[1] => Array (
[id] => 3
[children] => Array (
[0] => Array (
[id] => 2
[children] => null
[title] => Contact
[slug] => contact
[position] => 99
)
)
[title] => Suisse
[slug] => suisse
[position] => 1
)
) |
Then template code become as straightforward as
Code: | {foreach $data as $element}
{if $element@first}<ul>{/if}
<li><a href="{$element.slug}">{$element.title}</a>{if $element.children}
…reiterate…{/if}</li>
{if $element@last}</ul>{/if}
{/foreach} |
With your approach, you'd have to keep track of already rendered nodes. |

Hello,
thanks for your answer. How can I change my array? in my php code:
Code: |
function load_navigation() {
try {
$query = $this->_db->selectAllOrderBy("sys_navigation", "position");
$query->execute();
$navigations = array();
while($row = $query->fetch(\PDO::FETCH_ASSOC)) {
$navigations[] = array(
'id' => $row['id'],
'children' => $row['children'],
'title' => $row['title'],
'slug' => $row['slug'],
'position' => $row['position']
);
}
return $navigations;
} catch(PDOException $e) {
throw new Exception($e->getMessage());
}
}
| [/code] |

Change your database structure, so that children refer to parent, rather than parent refer to children.
Else you will need to run over your dataset twice at least to find all top-level elements. |
