Values from textbox array not updating - php

Question

I'm new in this forum and I'm having a hard time updating selected value from checkbox coming from the textbox value.
Scenario:
I want to update selected items, For example, I want to update Item-2 and the textbox from item received will be enabled, I will enter a number for example 1 and the textbox from total receive will automatically sum using AJAX.
The problem is after submitting the value from total receive the records that were updating is blank, but when I try to check and print_r the value is there.
And one more thing if all checkboxes are checked and enter a number for each item received, the value that it only get is the last value and will be updated will all selected checkbox.
Notes:
The checkbox is an array
Textbox from total receive is an array
Here's my UI:
Controller:
public function recitem_insert(){
$this->load->model('dbquery');
$check = $this->input->post('check');
$total_rec = $_POST['total_rec'];
if(isset($check)){ //Check if check is checked
for($i=0;$i<sizeof($check);$i++){
for($j=0;$j<sizeof($total_rec);$j++){
$updateData = array('rec_qty' => $total_rec[$j] );
$this->dbquery->modUpdatedynamicval('tblstock', 'id', $updateData, $check[$i]);
}
}//end for loop
echo "<script type='text/javascript'>
alert('Successfully Added!');
window.close();
</script>";
}else{ //End If
echo 'Please select a checkbox';
}
}
View:
<form method="post" action="<?php echo base_url() ?>user/recitem_insert">
<div class="box">
<div class="box-header">
<h3 class="box-title">System ID: <b><?php echo $process_id; ?></b></h3>
</div>
<!-- /.box-header -->
<div class="box-body">
<table id="example1" class="table table-bordered table-striped">
<thead>
<tr>
<th>Action</th>
<th>Item Code</th>
<th>Item Description</th>
<th>Required QTY Order</th>
<th>Last QTY Recieve</th>
<th>Item Recieve</th>
<th>Total Recieve</th>
</tr>
</thead>
<tbody>
<?php
$query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
foreach ($query->result() as $row){
?>
<tr>
<td><input type="checkbox" name="check[]" id="opt" value="<?php echo $row->id; ?>" onclick="valueChanged()"> </td>
<td><?php echo $row->item_code; ?></td>
<td><?php echo $row->description; ?></td>
<td><?php echo $row->qty_order; ?></td>
<td><?php echo $row->rec_qty; ?></td>
<input type="hidden" name="last_item_rec[]" value="<?php echo $row->rec_qty; ?>">
<td><input type="text" name="item_rec[]" id="txt" disabled=""></td>
<td><input type="text" name="total_rec[]"></td>
</tr>
<?php
}
?>
</tbody>
<tfoot>
</tfoot>
</table>
</div>
<!-- /.box-body -->
</div>
<div class="box-footer">
<button type="submit" class="btn bg-olive btn-flat margin">Submit</button>
</div>
</form>
Model:
public function modUpdatedynamicval($table, $column, $data, $equal_to){
$this->db->where($column, $equal_to);
$this->db->update($table, $data);
}
Edit
Let's assume:
I've input 1 in item_receive textbox one and the total receive will be 10,
2 in item_receive textbox two and the total receive will be 11,
3 in item_receive textbox three and the total receive will be 12,
CODE:
$check = $this->input->post('check');
$total_rec = $_POST['total_rec'];
echo 'Check Value';
print_r($check);
echo '<br><br>';
echo 'Total Recieve';
print_r($total_rec);
OUTPUT:
Check ValueArray ( [0] => 1 [1] => 2 [2] => 3 )
Total RecieveArray ( [0] => 10 [1] => 11 [2] => 12 )
But If I only input the second textbox here's the output:
Check ValueArray ( [0] => 2 )
Total RecieveArray ( [0] => [1] => 11 [2] => )

From what I see, you are having a problem to determine which input index is which on the back end. You could set an index key on each of the input like this :
<tbody>
<?php
$query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
foreach ($query->result() as $key => $row){ //added key to be used as inputs key
?>
<tr>
<td><input type="checkbox" name="check[<?php echo $key ?>]" id="opt" value="<?php echo $row->id; ?>" onclick="valueChanged()"> </td>
<td><?php echo $row->item_code; ?></td>
<td><?php echo $row->description; ?></td>
<td><?php echo $row->qty_order; ?></td>
<td><?php echo $row->rec_qty; ?></td>
<input type="hidden" name="last_item_rec[<?php echo $key ?>]" value="<?php echo $row->rec_qty; ?>">
<td><input type="text" name="item_rec[<?php echo $key ?>]" id="txt" disabled=""></td>
<td><input type="text" name="total_rec[<?php echo $key ?>]"></td>
</tr>
<?php
}
?>
</tbody>
After that, then replace the for loop :
for($i=0;$i<sizeof($check);$i++){
for($j=0;$j<sizeof($total_rec);$j++){
$updateData = array('rec_qty' => $total_rec[$j] );
$this->dbquery->modUpdatedynamicval('tblstock', 'id', $updateData, $check[$i]);
}
}//end for loop
With this foreach :
foreach ($check as $key => $item) {
$updateData = array('rec_qty' => $total_rec[$key] );
$this->dbquery->modUpdatedynamicval('tblstock', 'id', $updateData, $check[$key]);
}
So you don't manually check for the total_rec value but instead it only checks on submitted check post data.

Answer 2

from what i can see, like everybody else is saying, you have trouble in finding the correct rows of checked item.
I suggest you edit the way you name the form in multidimensional array. bet you didnt know that?
so in view.php
<form method="post" action="<?php echo base_url() ?>user/recitem_insert">
<div class="box">
<div class="box-header">
<h3 class="box-title">System ID: <b><?php echo $process_id; ?></b></h3>
</div>
<!-- /.box-header -->
<div class="box-body">
<table id="example1" class="table table-bordered table-striped">
<thead>
<tr>
<th>Action</th>
<th>Item Code</th>
<th>Item Description</th>
<th>Required QTY Order</th>
<th>Last QTY Recieve</th>
<th>Item Recieve</th>
<th>Total Recieve</th>
</tr>
</thead>
<tbody>
<?php
//WTF?? it's 2019. Say hello to SQL Injection
$query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
foreach ($query->result() as $i=>$row){
?>
<tr>
<td><input type="checkbox" name="data[<?php echo $i;?>][check]" id="opt" value="<?php echo $row->id; ?>" onclick="valueChanged()"> </td>
<td><?php echo $row->item_code; ?></td>
<td><?php echo $row->description; ?></td>
<td><?php echo $row->qty_order; ?></td>
<td><?php echo $row->rec_qty; ?></td>
<input type="hidden" name="data[<?php echo $i;?>][last_item_rec]" value="<?php echo $row->rec_qty; ?>">
<td><input type="text" name="data[<?php echo $i;?>][item_rec]" id="txt" disabled=""></td>
<td><input type="text" name="data[<?php echo $i;?>][total_rec]"></td>
</tr>
<?php
}
?>
</tbody>
<tfoot>
</tfoot>
</table>
</div>
<!-- /.box-body -->
</div>
<div class="box-footer">
<button type="submit" class="btn bg-olive btn-flat margin">Submit</button>
</div>
</form>
and you can easily cycle through the data for each rows while at the same time validating if the checkbox is checked
<?php
//simple way of traversing the data
if ( isset( $_POST['data'] ) )
{
echo '<table>';
foreach ( $_POST['data'] as $d )
{
//you have all the data here
//start checking on checked box
if(isset($d['check']))
{
echo '<tr>';
echo ' <td>', $d['last_item_rec'], '</td>';
echo ' <td>', $d['item_rec'], '</td>';
echo ' <td>', $d['total_rec'], '</td>';
echo '</tr>';
}
}
echo '</table>';
}

Can try with row key (item id). Update your array key with $row->id.
<tbody>
<?php
$query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
foreach ($query->result() as $row){
?>
<tr>
<td><input type="checkbox" name="check[]" id="opt" value="<?php echo $row->id; ?>" onclick="valueChanged()"> </td>
<td><?php echo $row->item_code; ?></td>
<td><?php echo $row->description; ?></td>
<td><?php echo $row->qty_order; ?></td>
<td><?php echo $row->rec_qty; ?></td>
<input type="hidden" name="last_item_rec[<?php echo $row->id; ?>]" value="<?php echo $row->rec_qty; ?>">
<td><input type="text" name="item_rec[<?php echo $row->id; ?>]" id="txt" disabled=""></td>
<td><input type="text" name="total_rec[<?php echo $row->id; ?>]"></td>
</tr>
<?php
}
?>
</tbody>
Scenraio Like:
1 item Id "2"
2 item Id "3"
3 item Id "5"
If you check first st row and first row item_id ($row->id) is 2 and enter 7 than you will get array like :-
print_r($_POST['total_rec']);
Output Like:
Array([2]=>7)
You can easy to find data using array key
Update:
<form method="post" action="<?php echo base_url(); ?>">
<div class="box">
<div class="box-header">
<h3 class="box-title">
System ID: <b> <?php echo '12'; ?></b>
</h3>
</div>
<!-- /.box-header -->
<div class="box-body">
<table id="example1" class="table table-bordered table-striped">
<thead>
<tr>
<th> Action</th>
<th>Item Code </th>
<th>Item Description</th>
<th>Required QTY Order</th>
<th>Last QTY Recieve</th>
<th>Item Recieve</th>
<th>Total Recieve</th>
</tr>
</thead>
<tbody>
<?php
//$query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
$new_item_list = array(
array('id'=> '1','item_code'=> 'ITEM-1','description' => 'ITEM Desc', 'qty_order'=> '2','rec_qty'=> '2'),
array('id'=> '2','item_code'=> 'ITEM-2','description' => 'ITEM Desc 2', 'qty_order'=> '3','rec_qty'=> '3' ),
array('id'=> '3','item_code'=> 'ITEM-3','description' => 'ITEM Desc', 'qty_order'=> '5','rec_qty'=> '4' ),
array('id'=> '4','item_code'=> 'ITEM-4','description' => 'ITEM Desc', 'qty_order'=> '1','rec_qty'=> '3' )
);
foreach ($new_item_list as $row){
?>
<tr>
<td><input type="checkbox" name="<?php echo $row['id']; ?>[check]" id="opt" value="<?php echo $row['id']; ?>" onclick="valueChanged()"> </td>
<td><?php echo $row['item_code']; ?></td>
<td><?php echo $row['description']; ?></td>
<td><?php echo $row['qty_order']; ?></td>
<td><?php echo $row['rec_qty']; ?></td>
<input type="hidden" name="<?php echo $row['id']; ?>[last_item_rec]" value="<?php echo $row['rec_qty']; ?>">
<td><input type="text" name="<?php echo $row['id']; ?>[item_rec]" id="txt" value='' ></td>
<td><input type="text" name="<?php echo $row['id']; ?>[total_rec]" value=''>
</td>
</tr>
<?php
}
?>
</tbody>
<tfoot>
</tfoot>
</table>
</div>
<!-- /.box-body -->
</div>
<div class="box-footer">
<button type="submit" class="btn bg-olive btn-flat margin">Submit</button>
</div>
</form>
Submit Action: For example
foreach($_POST as $key => $value){
if(isset($value['check'])){
//Row ID of item table $key
$total = $value['total_rec'] * $value['item_rec'];
echo "Total Number :".$total."</br>";
#here is your update query
}
}

If check checkbook and submit from then you will get output like

Answer 4

Your checkboxes all have the same ID, which always leads to problems. Change the id of the checkbox in the loop.
<td><input type="checkbox" name="check[]" id="opt-<?php echo $row->id; ?>" value="<?php echo $row->id; ?>" onclick="valueChanged()"> </td>
