Question

I need to display the previous value of the iterated array, here is code
<tr>
<th></th>
<th>Customer ID</th>
<th>Customer Name</th>
<th>Delivery Address</th>
<th>Contact No.</th>
<th>Zip Code</th>
<th>Payment Terms</th>
<th>Credit Limit</th>
</tr>
<?php $previousValue = null; ?>
#foreach($customer_count as $key => $value)
<tr>
<td>{{$previousValue=$value->customer_name }}</td>
<td>{{ $value->id }}</td>
<td>{{ $value->customer_name }}</td>
<td>{{ $value->delivery_address }}</td>
<td>{{ $value->contact_number }}</td>
<td>{{ $value->area_id }}</td>
<td>{{ $value->payment_term_id }}</td>
<td>{{ $value->credit_limit }}</td>
</tr>
#endforeach
I need to display the previous name of Customer in the iteration?
Any idea on how to do this?

Answer 1

Set value at the end , I set blank for first
#foreach($customer_count as $key => $value)
<tr>
<td>{{$previousValue or ""}}</td>
.....
.....
</tr>
<?php $previousValue = $value->customer_name ?>
#endforeach

Answer 2

$customer_count[$key - 1]
Of course you'll need to check if that exists or use the null-coalesce operator or something, so:
#php
$previous = $customer_count[$key - 1] ?? false;
#endphp
Then use:
#if( $previous )
... some stuff ...
#endif
wherever you need to inject.

Answer 3

please try this
<td>{{ (!$loop->first) ? $customer_count[$key - 1]->customer_name : '' }}</td>
You can read more about foreach loop here.

Answer 4

At very first set the previous value as blank and then at the bottom set value in $previousValue
<?php $previousValue = '';?>
#foreach($customer_count as $key => $value)
<tr>
<td>{{ $previousValue }}</td>
<td>{{ $value->id }}</td>
<td>{{ $value->customer_name }}</td>
<td>{{ $value->delivery_address }}</td>
<td>{{ $value->contact_number }}</td>
<td>{{ $value->area_id }}</td>
<td>{{ $value->payment_term_id }}</td>
<td>{{ $value->credit_limit }}</td>
</tr>
<?php $previousValue = $value->customer_name; ?>
#endforeach
