php save data into two rows at a time in database? - php

Question

I have a form like this
<form class="product-data" action="">
<table>
<tr class="data-row">
<td>
<input type="number" name="finance[a][source_unit]" >
</td>
<td >
<input type="number" name="finance[a][target_unit]">
</td>
<td>
<input type="number" name="finance[a][client_price]">
</td>
<td>
<input type="number" name="finance[a][client_salary]" >
</td>
</tr>
<tr class="data-row">
<td>
<input type="number" name="finance[b][source_unit]" >
</td>
<td >
<input type="number" name="finance[b][target_unit]">
</td>
<td>
<input type="number" name="finance[b][client_price]">
</td>
<td>
<input type="number" name="finance[b][client_salary]" >
</td>
</tr>
</table>
</form>
here you can see I have two rows. One for a and another for b. Now I want to save them in the database with two rows. One for the a and another for b at a same time. When I am doing print_r(finance). with this code
$finances = $_POST['finance'];
print_r($finances);
Its showing me an array like this
Array
(
[a] => Array
(
[source_unit] => 3213
[target_unit] => 657654322343
[client_price] => 5435.00
[client_salary] => 897.00
)
[a] => Array
(
[source_units] => 67656565
[target_units] => 43243
[client_price] => 23432.00
[client_salary] => 6546.00
)
)
Now can someone tell me how to save them in each row. I have my database table is like this and the data should be saved like this
Id, product_type, source_unit, target_unit, client_price, lient_salary
1 A 3213 657654322343 5435 897
2 B 67656565 43243 23432 6546

Answer 1

I have two solutions for you. Once that is tailored for this scenario only:
$f = $_POST['finance'];
// insert first row
$query = "INSERT INTO `table` VALUES (NULL, 'A', {$f['a']['source_unit']}, {$f['a']['target_units']}, {$f['a']['client_price']}, {$f['a']['client_salary']})";
mysql_query($query);
// insert second row
$query = "INSERT INTO `table` VALUES (NULL, 'B', {$f['b']['source_unit']}, {$f['b']['target_units']}, {$f['b']['client_price']}, {$f['b']['client_salary']})";
mysql_query($query);
or if you have it more universal (for multiple rows):
$f = $_POST['finance'];
foreach($f as $key => $item) {
// assign key of the letter as value to insert
$letter = strtoupper($key);
// insert a row
$query = "INSERT INTO `table` VALUES (NULL, '{$letter}', {$item['source_unit']}, {$item['target_units']}, {$item['client_price']}, {$item['client_salary']})";
mysql_query($query);
}

Answer 2

loop thru your array and either insert or update accordingly.
foreach($finances as $key => $data)
{
//based on the $key if value exists in database update else insert
echo $key.'<br />';
echo $data['source_unit'].'<br />';
echo $data['target_unit'].'<br />';
echo '<hr />';
}
