Using array after POST - php

Question

I would like to edit database entries with a simple form.
The id and name of each entry is fixed.
Problems:
After submitting the form $farray does only include the edited data of $array[3] not of the other records.
$farray doesn't include name and id (not included in the form). I need the id of the record for the query.
What could I use as a workaround?
Current script
<?php
$query = mysql_query("SELECT * FROM database");
$array = array();
while($row = mysql_fetch_assoc($query)){
$array[] = $row;
}
if(isset($_POST['send']))
{
$farray = $_POST['farray'];
foreach ($farray as $key => $value) {
echo('UPDATE database SET ' . $key . ' = "' . $value . '"' . ' WHERE id = ' . $farray['id']); //testing
}
}
?>
<form action=" <?=$_SERVER['PHP_SELF']?> " method="POST">
<?php
foreach($array as $key1){
echo $key1["name"] . "<br />";
foreach($key1 as $key => $value){
if ($key != "id" AND $key != "name") {
print $key.
' <input type="text" name="farray['.$key.']" value="'.$value.'"><br /><br />';
}
}
}
?>
<input type="submit" name="send" value="send">
</form>
Example $array
Array
(
[0] => Array
(
[id] => 0
[name] => name0
[1] => 1
[2] => 2
[3] => 3
)
[1] => Array
(
[id] => 1
[name] => name1
[1] => 1
[2] => 2
[3] => 3
)
[2] => Array
(
[id] => 2
[name] => name2
[1] => 1
[2] => 2
[3] => 3
)
[3] => Array
(
[id] => 3
[name] => name3
[1] => 1
[2] => 2
[3] => 3
)
)
Example $farray (after editing and submitting form)
Array
(
[1] => 10
[2] => 20
[3] => 30
)

OK, even though your table fields are not 1, 2, and 3, you just needed to change up your posted array a little. So I made you a little example:
<form method="post">
<?php
// Simulate DB records
$array = [
[
'id' => 0,
'name' => 'name0',
'1' => 1,
'2' => 2,
'3' => 3
],
[
'id' => 1,
'name' => 'name1',
'1' => 1,
'2' => 2,
'3' => 3
],
[
'id' => 2,
'name' => 'name2',
'1' => 1,
'2' => 2,
'3' => 3
]
];
// Create the input fields:
foreach( $array as $key1 )
{
echo $key1["name"] . "<br />";
foreach($key1 as $key => $value)
{
if ($key != "id" AND $key != "name")
{
echo $key.
' <input type="text" name="farray[' . $key1['id'] . ']['.$key.']" value="'.$value.'"><br /><br />';
}
}
}
?>
<button type="submit">Submit</button>
</form>
<pre>
<?php
if( isset( $_POST['farray'] ) )
{
print_r( $_POST );
foreach( $_POST['farray'] as $id => $values )
{
foreach( $values as $k => $v )
{
echo('UPDATE database SET ' . $k . ' = "' . $v . '"' . ' WHERE id = ' . $id ) . '<br />';
}
}
}
?>
</pre>
I tested this, and I think it works as you would expect.
