Pull bulleted list from MySQL in php - php

Question

Trying to produce a bulleted list from text field in MySQL - I have the bullets in the DB field : I'm pulling data into the array $products, I need the string in array to be formatted as a bullet list in the products $Keyfindings2 results
<?php
/* This controller renders the category pages */
class CategoryController{
public function handleRequest(){
$cat = Category::find(array('id'=>$_GET['category']));
if(empty($cat)){
throw new Exception("There is no such category!");
}
// Fetch all the categories:
$categories = Category::find();
// Fetch all the products in this category:
$products = Product::find(array('category'=>$_GET['category']));
// $categories and $products are both arrays with objects
$Keyfindings2 = explode('•', $products);
echo "<ul style=\' list-style-type:upper-roman;\'>\n";
foreach( $Keyfindings2 as $item )
{
echo "<li>$item</li><br />\n";
}
echo "</ul>";
render('category',array(
'title' => 'Browsing '.$cat[0]->name,
'categories' => $categories,
'products' => $Keyfindings2
));
}
}
?>
UPDATE: now getting 'undefined variable' in other part of code on line 1:
<li <?php echo ($active == $category->id ? 'data-theme="a"' : '') ?>>
<a href="?category=<?php echo $category->id?>" data-transition="fade">
<?php echo $category->name ?>
<span class="ui-li-count"><?php echo $category->contains?></span></a>
</li>

Answer 1

You problem is quite simple: you are using explode on the wrong thing.
If your code/comments is right $products is an array and you explode it. You probably have your PHP error level too low because this produce a PHP warning: PHP Warning: explode() expects parameter 2 to be string, array given in php shell code on line 1
So from there 2 solutions: either $products is an array of strings and you can do
function myExplode($product) {
return explode('•', $product);
}
$Keyfindings2 = array_map('myExplode', $products);
or $products is an array of objects (as your code comment suggests) and you go with:
function myExplode($product) {
// well actual the name of the field or method to call really depends on your
// code and there is no way we can tell it with what we have on your post
// so consider this an example
return explode('•', $product->productFieldContainingList);
}
$Keyfindings2 = array_map('myExplode', $products);
With either solution the goal is the same: to apply explode on the correct data, not on an array containing that data.
