Update Array Data In Laravel

Question

I have already done creating a form that can submit array data, however I am having problem on updating the array when user wants to edit the form data.

Here is in the view

@foreach($prescriptions as $prescription)

  <input type="hidden" name="prescript_id[]" value="{!! $prescription->prescript_id !!}"> 
    <tr> 
       <td><input class="form-control" name="drugname[]" type="text" value="{{ $prescription->drugname }}"></td>
       <td><input class="form-control" id="drugdosage" name="drugdosage[]" type="text" value="{{ $prescription->drugdosage }}"></td>
       <td><input class="form-control" id="frequency" name="frequency[]" type="text" value="{{ $prescription->frequency }}"></td>
      <td><input class="form-control" id="notes" name="notes[]" type="text" value="{{ $prescription->notes }}"></td>
      <td>RM <input class="form-control" id="price" name="price[]" placeholder="0.00" type="text" value="{{ $prescription->price }}"></td>
      <td><a class="btn del">-</a></td>
 </tr>@endforeach

And here is in my controller on updating the data

public function update($consultid, Request $request)
{

        $docadvice = $request->get('docadvice');

        $drugnames = $request->get('drugname');
        $drugdosage = $request->get('drugdosage');
        $frequency = $request->get('frequency');
        $notes = $request->get('notes');
        $price = $request->get('price');

        $prescriptid = $request->get('prescript_id');

        $prescription = Prescription::where('prescript_id', '=', $prescriptid)->first();

            $count_items = count($drugnames);

        for($i = 0; $i<$count_items; $i++)
        {

            Prescription::where('prescript_id', '=', $prescriptid)->update([

            'drugname' => $drugnames[$i],
            'drugdosage' => $drugdosage[$i],
            'frequency' => $frequency[$i],
            'notes' => $notes[$i],
            'price' => $price[$i],
            'doc_advice' => $docadvice,

            ]);

        }

        return redirect(action('Doctor\PrescriptionController@edit', $consultation->consult_id))->with('status', 'The prescription has been updated!');
}

When I try to run the code, it is only takes the last values i have inserted not all values of rows updated (Assume there are two rows, when I inserted

row 1: Drug 1 row 2: Drug 2

Only Drug 2 will be updated on both rows. row 1: Drug 2 row 2: Drug 2

Upon request I check on dd($request->toArray()); all data inserted are read

Help me on how to update for both rows and for your information, I have created a dynamic table to add new row but it won't add the new row in database but only takes the last value to be updated for rows existed. Thank you.

This the table prescription

I take out the hidden field and change to text

<div class="table-responsive">
            <table class="tblform table table-bordered table-striped table-hover">

public function update($consultid, Request $request)

Answer 2

Please try this:

 public function update($consultid, Request $request) {

        $docadvice = $request->get('docadvice');

        $drugnames = $request->get('drugname');
        $drugdosage = $request->get('drugdosage');
        $frequency = $request->get('frequency');
        $notes = $request->get('notes');
        $price = $request->get('price');

        $prescriptid = $request->get('prescript_id');

        $prescription = Prescription::where('prescript_id', '=', $prescriptid)->first();

            $count_items = count($drugnames);

        for($i = 0; $i<$count_items; $i++)
        {

            $pres = Prescription::where('prescript_id', $prescriptid[$i])->first();

            $pres->update([
            'drugname' => $drugnames[$i],
            'drugdosage' => $drugdosage[$i],
            'frequency' => $frequency[$i],
            'notes' => $notes[$i],
            'price' => $price[$i],
            'doc_advice' => $docadvice,
            ]);

        }

        return redirect(action('Doctor\PrescriptionController@edit', $consultation->consult_id))->with('status', 'The prescription has been updated!'); }

Answer 3

正如您所看到的$prescriptid是一个数组，因此您必须在编写$drugnames将其写入循环中，例如 `$prescriptid[$i]``

Answer 4

$prescription = Prescription::findOrFail($prescriptid)->get();
$count_items = count($drugnames);

for($i = 0; $i<$count_items; $i++)
{
    $prescription[$count_items]->update([
        'drugname' => $drugnames[$i],
        'drugdosage' => $drugdosage[$i],
        'frequency' => $frequency[$i],
        'notes' => $notes[$i],
        'price' => $price[$i],
        'doc_advice' => $docadvice,
    ]);
}
