I want to get the old value from dynamic input on Laravel. If it's a regular input, I only need{{ old ('name') }}. But what if the input is dynamic?
View
<tr>
<td>
<input type="text" name="name_progress[]"
value="{{ old('name_progress[]') }}"
placeholder="Enter name" class="form-control"/>
</td>
<td>
<input type="text" name="payment_percentage[]"
value="{{ old('payment_percentage[]') }}"
placeholder="Enter % invoice" class="form-control"/>
</td>
<td>
<a type="button" class="btn btn-danger remove-tr">-</a>
</td>
</tr>
JavaScript
<script type="text/javascript">
$("#add-btn").click(function () {
var tr = '<tr>' +
'<td>' +
'<input type="text" name="name_progress[]" ' +
'placeholder="Enter name" class="form-control" /></td>' +
'<td><input type = "text" name = "payment_percentage[]" ' +
'placeholder = "Enter per_invoice" class = "form-control" />' +
'</td>' +
'<td><a type="button" class="btn btn-danger remove-tr">-</a></td>' +
'</tr>';
$("#dynamicProgress").append(tr);
});
$(document).on('click', '.remove-tr', function () {
$(this).parents('tr').remove();
});
</script>
Sincename_progress andpayment_percentage fields are arrays, you may simply loop through the old input values.
@forelse (old('name_progress', []) as $i => $name_progress)
<tr>
<td>
<input type="text" name="name_progress[]" value="{{ $name_progress }}" placeholder="Enter name" class="form-control" />
</td>
<td>
<input type="text" name="payment_percentage[]" value="{{ old('payment_percentage')[$i] }}" placeholder="Enter % invoice" class="form-control" />
</td>
<td>
<a type="button" class="btn btn-danger remove-tr">-</a>
</td>
</tr>
@empty
<tr>
<td>
<input type="text" name="name_progress[]" placeholder="Enter name" class="form-control" />
</td>
<td>
<input type="text" name="payment_percentage[]" placeholder="Enter % invoice" class="form-control" />
</td>
<td>
<a type="button" class="btn btn-danger remove-tr">-</a>
</td>
</tr>
@endforelse
Ifold('name_progress') is empty or null, initial fields with empty values will be displayed.
