store associative array to mysql database - php

Question

I have table which is dynamically generated. I am getting all correct data. I want to store html data to database table. So how do I store it? following is the code for html table
foreach($res->result() as $row ){
echo "<tr>";
echo "<td><input type='hidden' style='width:80%;' value='".$row->product_id."'
name='product_id[]'/></td>";
echo "<td><input type='hidden' style='width:80%;' value='".$product_name."'
name='product_name[]'/></td>";
echo "</tr>";
echo "<tr>";
echo "<td style='width:40%;'>".$product_name."</td>";
echo "<td><input type='text' style='width:30%;' id='packing' name='packing[]'/></td>";
echo "<td><input type='text' class='quantity' style='width:80%;' readonly=''
value='".$row->quantity."' name='quantity[]'/></td>";
echo "<td><input type='text' name='rate' style='width:80%;' class='rate'
name='rate[]'/></td>";
echo "<td><input type='text' style='width:100%;' class='amount' readonly=''
name='amount[]'/></td>";
echo "</tr>";
}
On form submit I have done this..
$data['cart']=array(
'product_id'=>$this->input->post('product_id'),
'product_name'=>$this->input->post('product_name'),
'packing'=>$this->input->post('packing'),
'quantity'=>$this->input->post('quantity'),
'rate'=>$this->input->post('rate'),
'amount'=>$this->input->post('amount'),
);
print_r($data);
$i=0;
foreach($data['cart'] as $row){
$product_id=$row['product_id'];
$product_name=$row['product_name'];
$packing=$row['packing'];
$quantity=$row['quantity'];
$rate=$row['rate'];
$amount=$row['amount'];
$query = $this->db->query("insert into
phppos_billing_items(product_id,product_name,packing,quantity,rate,amount) values
('$product_id','$product_name','$packing','$quantity','$rate','$amount')");
$i++;
}
But it displaying only last record in table..Anybody has any idea about this?? I want total table records to save in another table.

Answer 1

$product_id =$this->input->post('product_id'),
$product_name =$this->input->post('product_name'),
$packing =$this->input->post('packing'),
$quantity =$this->input->post('quantity'),
$rate =$this->input->post('rate'),
$amount =$this->input->post('amount'),
$total = count ($product_id);
for($i=0;$i<$total;$i++){
$query = $this->db->query("insert into
phppos_billing_items(product_id,product_name,packing,quantity,rate,amount) values
("$product_id[$i]","$product_name[$i]","$packing[$i]","$quantity[$i]","$rate[$i]","$amount[$i]")");
}
But it will gives error when no data found for any data So please validate all fields before this code

Answer 2

The trick here is to use the [] notation in your HTML form elements.
So instead of this:
<input type='text' name='someVar'/>
You have:
<input type='text' name='someVar[]'/>
If you have specific keys you can do:
<input type='text' name='someVar[myKey1]'/>
In your case I would do this (HTML generation):
foreach($res->result() as $row ){
echo "<tr>";
echo "<td><input type='hidden' value='".$row->product_id."' name='product_id[]'/></td>";
echo "<td><input type='hidden' value='".$product_name."' name='product_name[]'/></td>";
echo "</tr>";
echo "<tr>";
echo "<td style='width:40%;'>".$product_name."</td>";
echo "<td><input type='text' name='packing[]'/></td>";
echo "<td><input type='text' class='quantity' readonly='' value='".$row->quantity."' name='quantity[]'/></td>";
echo "<td><input type='text' name='rate' class='rate' name='rate[]'/></td>";
echo "<td><input type='text' class='amount' readonly='' name='amount[]'/></td>";
echo "</tr>";
}
Notice the [] after every input name? And this would be the code that responds to the form submission:
foreach ($_GET['product_id'] as $index => $product_id) {
$product_id = $_GET['product_id'][$index];
$product_name = $_GET['product_name'][$index];
$packing = $_GET['packing'][$index];
$quantity = $_GET['quantity'][$index];
$rate = $_GET['rate'][$index];
$amount = $_GET['amount'][$index];
phppos_billing_items(product_id,product_name,packing,quantity,rate,amount) values ('$product_id','$product_name','$packing','$quantity','$rate','$amount')");
}
