I’m trying to dynamically assemble a menu with submenus with data coming from a database table, but I couldn’t get a result that worked.
I have this code to create the menu and submenu on another site, but the way to create the menu of the other site was different (only ul and li more simply) and could not adapt to reach the result I hope (end of the question).
<?php
$items = array ( 1 => array ( 'parent' => '0', 'tit_pag' => 'Inicial', 'url_pag' => '/', 'target_url' => '_self', 'id' => '1', ), 2 => array ( 'parent' => '0', 'tit_pag' => 'Principal 1', 'url_pag' => '/', 'target_url' => '_self', 'id' => '2', 'child' => array ( 3 => array ( 'parent' => '2', 'tit_pag' => 'Item 1', 'url_pag' => 'link1.html', 'target_url' => '_self', 'id' => '3', ), 4 => array ( 'parent' => '2', 'tit_pag' => 'Item 2', 'url_pag' => 'link2.html', 'target_url' => '_self', 'id' => '4', ), 5 => array ( 'parent' => '2', 'tit_pag' => 'Item 3', 'url_pag' => 'link3.html', 'target_url' => '_self', 'id' => '5', ), ), ), 6 => array ( 'parent' => '0', 'tit_pag' => 'Principal 2', 'url_pag' => '#', 'target_url' => '_self', 'id' => '6', 'child' => array ( 7 => array ( 'parent' => '6', 'tit_pag' => 'Item 4', 'url_pag' => 'link4.html', 'target_url' => '_self', 'id' => '7', ), 8 => array ( 'parent' => '6', 'tit_pag' => 'Item 5', 'url_pag' => 'link5.html', 'target_url' => '_self', 'id' => '8', ), 9 => array ( 'parent' => '6', 'tit_pag' => 'Item 6', 'url_pag' => 'link6.html', 'target_url' => '_self', 'id' => '9', ), ), ), 10 => array ( 'parent' => '0', 'tit_pag' => 'Principal 3', 'url_pag' => 'link7.html', 'target_url' => '_self', 'id' => '10', ), 11 => array ( 'parent' => '0', 'tit_pag' => 'Principal 4', 'url_pag' => 'link8.html', 'target_url' => '_self', 'id' => '11', ), );
function get_menu($items) {
$html = "<ul>";
foreach($items as $key=>$value) {
$html.= '<li><a href="/'.$value['url_pag'].'" target="'.$value['target_url'].'">'.$value['tit_pag'].'</a>';
if(array_key_exists('child',$value)) {
$html .= get_menu($value['child'],'child');
}
$html .= "</li>";
}
$html .= "</ul>";
return $html;
}
print get_menu($items);
?>
The above code generates the following result:
<ul>
<li><a href="//" target="_self">Inicial</a></li>
<li>
<a href="//" target="_self">Principal 1</a>
<ul>
<li><a href="/link1.html" target="_self">Item 1</a></li>
<li><a href="/link2.html" target="_self">Item 2</a></li>
<li><a href="/link3.html" target="_self">Item 3</a></li>
</ul>
</li>
<li>
<a href="/#" target="_self">Principal 2</a>
<ul>
<li><a href="/link4.html" target="_self">Item 4</a></li>
<li><a href="/link5.html" target="_self">Item 5</a></li>
<li><a href="/link6.html" target="_self">Item 6</a></li>
</ul>
</li>
<li><a href="/link7.html" target="_self">Principal 3</a></li>
<li><a href="/link8.html" target="_self">Principal 4</a></li>
</ul>
But the result I needed was this:
<ul class="nav navbar-nav">
<li><a href="//" target="_self">Inicial</a></li>
<li class="dropdown submenu">
<a href="//" target="_self" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Principal 1 <i class="fa fa-angle-down" aria-hidden="true"></i></a>
<ul class="dropdown-menu">
<li><a href="link1.html" target="_self">Item 1</a></li>
<li><a href="link2.html" target="_self">Item 2</a></li>
<li><a href="link3.html" target="_self">Item 3</a></li>
</ul>
</li>
<li class="dropdown submenu">
<a href="/#" target="_self" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Principal 2 <i class="fa fa-angle-down" aria-hidden="true"></i></a>
<ul class="dropdown-menu">
<li><a href="/link4.html" target="_self">Item 4</a></li>
<li><a href="/link5.html" target="_self">Item 5</a></li>
<li><a href="/link6.html" target="_self">Item 6</a></li>
</ul>
</li>
<li><a href="/link7.html" target="_self">Principal 3</a></li>
<li><a href="/link8.html" target="_self">Principal 4</a></li>
</ul>
Important you [Dit] your question and explain objectively and punctually the difficulty found, accompanied by a [mcve] of the problem and attempt to solve.

Your menu is basically
<ul>and<li>, I didn’t understand what the difficulty was. What was the HTML generated by this code for the data you presented? What is the difference with the desired HTML?– Woss
I edited the question, see that the result that PHP generates is different from the result I needed, but I could not edit the code so I could leave it equal.
– Frederico Moreira
@Woss but the question depends on the result of the database that at each insertion can change the result of the items. As I said this result is php yes, because I use it on another site and it is working and generates this result. The variable
itemswill receive the data from the database– Frederico Moreira
@Woss a doubt, is appearing to you the image of the print of the database? Why the data
itemsare in the picture– Frederico Moreira
Give a
var_dump($items)before calling the function and include the result of that in the question.– bfavaretto
I put the value of
$itemsin the personal code and I took the reference to the bank, forgive my ignorance– Frederico Moreira
I edited the question, leaving only the part that matters. Result that generates PHP and expected result!
– Frederico Moreira
Note that in your data no item has the Child key, so it never enters the if inside the function.

@bfavaretto the code returns the correct result, the problem is on how to add the other information I need to make it equal to the second code posted.
