Get values from HTML in a multidimensional array and calculate values using PHP
- by Frank Nwoko
I have searched but could not get solution on this issue.
I am working on an application which will generate unknown number of items and have users select the quantity from a drop down against each item. Eg.
Item(s) | price | Select qty
Rice 23 3
Beans 22 4
Eggs 52 5
...
...
...
unknown
Please, how can I capture the above in an array and also calculate the total value for all selected items and corresponding fees?
I have the following HTML code:
<form id='form1' name='form1' method='post' action='item_calc.php'>
<?php
.....
while($t_row = mysql_fetch_assoc($get_items)) {
echo "<p><label>$t_row['$item_name']
<input type='text' READONLY name='item_price[]' value='$t_row['$item_price']' /></label>
<input type='text' READONLY name='item_fees[]' value='$t_row['$item_fee']' />
<select name="item_qty">
<option value="1">
<option value="2">
<option value="3">
<option value="4">
<option value="5">
</select>
</p><p>";
}
echo "<label><input type='submit' name='submit' value='Submit' /></label></p>
</form>";
Please, how can I get item_price[] + item_fees[] * item_qty for all selected items?
This is what I have tried:
for ($i = 0; $i < count($_POST['item_price']); $i++) {
// Do something here with $_POST['checkbx'][$i]
foreach ($_POST['item_fees'] as $tkey => $tvalue) {
//echo "Key: $tkey; Value: $tvalue<br>";
}
foreach ($_POST['item_price'] as $pkey => $pvalue) {
//echo "Key: $pkey; Value: $pvalue<br>";
}
$total = $tvalue + $pvalue;
}
echo $total;
