[英]Insert all the values in a row based on a selected checkbox
I have the following table that fetches data from the database: 我有下表从数据库中获取数据:
while($row = mysql_fetch_array($result))
{
echo '
<tr>
<td width="320">
<input type="checkbox" name="product_ID[]" value="'.$row['Product_ID'].'" />'.$row['Product_description'].'<br />
</td>
<td width="50">
<input type="text" name="product_cost[]" value="'.$row['Product_Retail_cost'].'" maxlength="3" size="3" />
</td>
<td width="50">
<input type="text" name="product_quantity[]" value="1" maxlength="3" size="1" />
</td>
</tr>';
}
What I would like to do, is insert the row into a table, making sure to insert any updated values from the two text boxes. 我想做的是将行插入表中,确保从两个文本框中插入任何更新的值。 The insert looks like this:
插入看起来像这样:
$product_ID = $_POST['product_ID'];
$product_cost = $_POST['product_cost'];
$product_quantity = $_POST['product_quantity'];
for ($i=0; $i<sizeof($product_ID);$i++)
{
$query="INSERT INTO mjj_ordered_products
(`Order_ID`,
`Product_ID`,
`Product_Quantity`,
`Product_Price`)
VALUES ((SELECT MAX(Order_ID) AS Order_ID FROM `mjj_orders`),
'".$product_ID[$i]."',
'".$product_quantity[$i]."',
'".$product_cost[$i]."')";
mysql_query($query) or die (mysql_error());
}
But while this inserts the correct Product_ID, the remaining two values inserted do not correspond to the selected checkbox, but rather by looping through the entire list. 但是,尽管这会插入正确的Product_ID,但是插入的其余两个值并不对应于选定的复选框,而是通过遍历整个列表。
The question: how do I insert the other 2 values associated to the checkbox into the databse? 问题:如何将与复选框关联的其他2个值插入数据库?
Assuming the Product_ID is unique, you can pass it as the index in all arrays like 假设Product_ID是唯一的,则可以将其作为索引在所有数组中传递,例如
<input type="text" name="product_cost['.$row['Product_ID'].']" value="'.$row['Product_Retail_cost'].'" maxlength="3" size="3" />
And then do something like 然后做类似的事情
foreach($product_ID as $id)
{
$query="INSERT INTO mjj_ordered_products
(`Order_ID`,
`Product_ID`,
`Product_Quantity`,
`Product_Price`)
VALUES ((SELECT MAX(Order_ID) AS Order_ID FROM `mjj_orders`),
'".$product_ID[$id]."',
'".$product_quantity[$id]."',
'".$product_cost[$id]."')";
mysql_query($query) or die (mysql_error());
}
