Array multi-dimensional error PHP - php

Question

<?php
$ctr = 0;
foreach($rows as $row){
?>
<input type="hidden" name="client<?php echo $ctr; ?>['client_id']" value="<?php echo $row['client_id']; ?>">
<input type="hidden" name="client<?php echo $ctr; ?>['transaction_id']" value="<?php echo $row['id']; ?>">
<input style="max-width: 100px;min-width:100px;" class="form-control right" type="text" name="client<?php echo $ctr;?>['amount']" value="" />
<?php
}
?>
Update: I have included the form where $_POST coming from.
This it the output of print_r ($_POST);:
Array
(
[client0] => Array
(
['client_id'] => 1
['transaction_id'] => 1
['amount'] => 1000
['mode'] => cash
)
[client1] => Array
(
['client_id'] => 2
['transaction_id'] => 5
['amount'] => 600
['mode'] => cash
)
[client2] => Array
(
['client_id'] => 3
['transaction_id'] => 6
['amount'] => 200
['mode'] => cash
)
[save] =>
)
When I try writing this: echo $_POST['client0']['amount'];.
I'm expecting an output of 1000
but it gives me an error like this: Notice: Undefined index: amount.
So guys can you please tell me whats wrong with my code.TIA

Answer 1

Compare the print_r output carefully. One key is given as client0 while the next is given as 'amount'. That's because your key is actually 'amount', not amount. Because you're including unnecessary quotes in your HTML. Fix your HTML so the input name becomes:
name="client0[amount]"
(Or alternatively address the key as $_POST['client0']["'amount'"].)
And while you're at it, you may want to rename your fields to:
name="clients[0][amount]"
Because then you can simply traverse the data using:
foreach ($_POST['clients'] as $client) {
echo $client['id'], $client['amount'], ..;
}
Which is much more readable and sane.

Answer 2

You should use
echo $_POST['client0']['amount'];

Answer 3

You are using wrong variable amount_id just check it out your array having variable is "amount" so change the variable name like bellow
echo $_POST['client0']['amount'];
I hope this will help you.

Answer 4

Try this way ..
foreach ($_POST['client0'] as $val) {
echo $val['amount'] ;
}
