PHP - Query and function and while clause? - php

Question

Question: How can I tie together my query with my function? I would like to print my list, but I am not sure how to connect the two. Also, am I using "entries" correctly below?
/* data handling */
$result = mysql_query("SELECT * FROM Items LEFT JOIN Categories on Categories.CategoryID = Items.FK_CategoryID WHERE Items.FK_UserID = $_SESSION[user_id] ORDER BY CategorySort, CategoryName ASC, ItemSort, ItemTitle");
/* output logic */
function render_list($ItemTitle, array $entries)
{
echo '<ul><li>' . $ItemTitle . '<ul>';
foreach($entries as $entry)
{
echo '<li>' . $entry['ItemID'] . '</li>';
}
echo '</ul></li></ul>';
}
render_list();
Do I need to use a while clause?
// loop through topics
while($row = mysql_fetch_array($result)) {
render_list;
}

Yeah, replace your foreach loop with that while loop. Take that "type" (array) out of the function definition though, you don't need to do that in loosely typed php language. Here's a rework of the code you have:
/* output logic */
function render_list($ItemTitle, $entries)
{
echo '<ul><li>' . $ItemTitle . '<ul>';
while($entry = mysql_fetch_array($entries))
{
echo '<li>' . $entry['ItemID'] . '</li>';
}
echo '</ul></li></ul>';
}
$result = mysql_query("SELECT * FROM Items LEFT JOIN Categories on Categories.CategoryID = Items.FK_CategoryID WHERE Items.FK_UserID = $_SESSION[user_id] ORDER BY CategorySort, CategoryName ASC, ItemSort, ItemTitle");
render_list('My Title', $result);
