php foreach returns last variable selected - php

Question

the foreach doesn't seem to work correctly in which the last value selected is working but not all.
The array is selected from here:
<fieldset>
<legend>status:</legend>
<?php foreach ($statuss as $status): ?>
<div><label for="status<?php hscout($status['id']);
?>"><input type="checkbox" name="statuss1[]"
id="status<?php hscout($status['id']); ?>"
value="<?php hscout($status['id']); ?>"<?php
if ($status['selected'])
{
echo ' checked="checked"';
}
?>/><?php hscout($status['description']); ?></label></div>
<?php endforeach; ?>
</fieldset>
The index is as follows:
if (isset($_POST['statuss1']))
{
foreach ($_POST['statuss1'] as $status1)
{
$a = mysqli_real_escape_string($link, $status1);
$sql = "SELECT b FROM C WHERE d ='$a'";
$result = mysqli_query($z, $sql);
if (!$result)
{
$error = 'Still not working you.....';
include 'error.html.php';
exit();
}
$selected1s = array();
while ($row = mysqli_fetch_array($result))
{
$selected1s[] = $row['b'];
}
}
}
the $selected1s[] works only if one variable is selected. If multiple variables are selected, the last variable is parsed through.

Answer 1

Every time through the foreach loop that fetches the selected items, you say $selected1s = array(), which clears out the array you're using to accumulate them.
Take the line that says $selected1s = array(); and move it to before the foreach loop, if you just want to get this code working.
There's a way to build one query that gets all the rows at once, though. That typically beats the pants off doing a whole bunch of queries for one item each.
$selected1s = array();
if (!empty($_POST['statuss1'])) {
// Create a function that SQL-escapes and quotes an ID...
// (Note: requires PHP 5.3+)
$sqlify = function($id) use ($link) {
return "'" . mysqli_real_escape_string($link, $id) . "'";
};
// and apply it to the array to get back a list of SQL-ready values
$ids = array_map($sqlify, $_POST['statuss1']);
// string them together as a comma-separated list
$ids_sql = implode(',', $ids);
// and say `d IN (the list)`
$sql = "SELECT b FROM c WHERE d IN ($ids_sql)";
... do the query, fetch results into $selected1s
}
(This is the part where i'd normally advocate prepared statements and tell you to use them. Which you should, in most cases. For IN queries or the equivalent OR queries, though, they tend to suck.)
