how to properly transfer user input from index to invoice?
- by Romel
I got a dillema, I'm trying to find a solution for my code. How do I make it so that when the user inputs a given quantity in the text box from the index.php it will transfer that input quantity to the invoice.php. I've tried doing the post method but it seems like it's not working :/ As always, any help or suggestions will be greatly appreciated! I hope it's something simple:( Here's my code:
index.php
<html>
<style>
body{
background-image: url('URL HERE');
font-family: "Helvetica";
font-size:15px;
}
h1{
color:black;
text-align:center;
}
p{
font-size:15px;
}
</style>
<h1>
STORE TITLE HERE
</h1>
<body>
<form action="login.php" method="post">
<?php
//Include products info.inc (Which holds all our product arrays and info)
//Credit: Tracy & Mark (THank you!)
include 'products_info.inc';
/*The following code centers my table on the page, makes the table background white,
makes the table 50% of the browser window, gives it a border of 1 px,
gives a padding of 2 px between the cell border and content, and gives 1 px of spacing between cells.
*/
echo "<table align=center bgcolor='FFFFFF' width=50% border=1 cellpadding=1
cellspacing=2>";
//Credit: Tracy & Mark (THank you!)
echo '<th>Product</th> <th>Description</th> <th>Price</th> <th>Quantity</th>';
//The following code loops through the whole table body and then prints each row.
for($i=0; $i<count($allfood); $i++)
{
//Credit: Tracy & Mark (THank you!)
echo "<tr align=center>";
echo "<td>{$allfood[$i]['Product']}</td>";
echo "<td>{$allfood[$i]['Description']}</td>";
echo "<td>{$allfood[$i]['Price']}</td>";
echo "<td>{$allfood[$i]['Quantity']}</td>";
echo "</tr>";
}
//This code ends the table.
echo "</table>";
echo "<br>";
?>
<br><center><input type='submit' name='purchase' value='Purchase'></center>
</form>
</body>
</html>
And here's my invoice.php
<html>
<style>
body{
background-image: url('URL HERE');
font-family: "Helvetica";
font-size:15px;
}
h1{
color:black;
text-align:center;
}
p{
font-size:15px;
}
</style>
<h1>
Invoice
</h1>
</html>
<?php
//Include products info.inc (Which holds all our product arrays and info)
//Credit: Tracy & Mark (Thank you!)
include 'products_info.inc';
//Display the invoice & 'WELCOME USER. THANK YOU FOR USING THIS DAMN THING msg'
/*The following code centers my invoice table on the page, makes the table background white,

echo "<table align=center bgcolor='FFFFFF' width=50% border=1 cellpadding=1cellspacing=2>";

echo "<td align=center><b>Product</b></td>";
echo "<td align=center><b>Quantity</b></td>";

for($i=0; $i<count($allfood); $i++)

echo "<td align=center>$extendedprice</td>";
