order form script within a table

paldo

Hallo

with your help we previously have create a basic order script. What I want to change is to have the form as a table.
I would like to have a table with 1 row and 3 columns. On the first column I will have an image, on the second the text field were the visitor will insert the value (quantity), the third column a small explanation text ( item1 for 10$ ).

I tried but I get an error message because of the table. Can someone help me out?
Here the script without table:

<?php
session_start();
echo "<form name=\"aaaa\" method=\"post\"  action=\"order.php\">";
echo '<input name="quantity1" type="text" value="'.    (!empty($_SESSION["quantity1"]) ? htmlspecialchars($_SESSION["quantity1"]):"" ).'">item1 for 10$<br/><br />'."\n";

echo '<input name="submit" type="submit" value="order">';
print '</form>';

?>

why don't you use a visual html editor?

<table width="457" border="1">
  <tr>
    <td width="125" align="center" valign="top">#image#</td>
    <td width="125" align="center" valign="top">
<input name="quantity1" type="text" value="<?php echo (!empty($_SESSION["quantity1"]) ? htmlspecialchars($_SESSION["quantity1"]):"" ) ; ?>"></td>
    <td width="125" align="center" valign="top">#itemprice#</td>
  </tr>
</table>
<br /><input name="submit" type="submit" value="order">

Thank you djjjozsi

I work with dreamweaver 8 but I didn't make the changes to preview php scripts. I will do it soon.

I change the script to the following:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Untitled Document</title>
</head>

<body>
<?php
session_start();
echo "<form name=\"aaaa\" method=\"post\"  action=\"order_table.php\">";
?>
<table width="457" border="1">
  <tr>
    <td width="125" align="center" valign="top">#image#</td>
    <td width="125" align="center" valign="top">
<input name="quantity1" type="text" value="<?php echo (!empty($_SESSION["quantity1"]) ? htmlspecialchars($_SESSION["quantity1"]):"" ) ; ?>"></td>
    <td width="125" align="center" valign="top">item1 for 10$</td>
  </tr>
</table>
<br /><input name="submit" type="submit" value="order">
</body>
</html>

I would like one more improvement:
the value that has to be inserted must be a multiple of 6( 6,12,18, 24....).

How should the script look like?

Here the script that has to be revised:

<?php
session_start();  

$_SESSION['quantity1'] = $_POST['quantity1'];
?>

<?php
$quantity1 = $_POST['quantity1'];
if ($_POST['quantity1'] != 0) {
print "you ordered $quantity1 item1.<br />";
}

if ($_POST['quantity1'] != 6) {

print "you must order a multiple of 6.<br />";
}

?>

<input type="submit" name="submit" style="background-color:#00CC66" value="  I confirm my order" onClick="location.href='confirm.php'">



<a href="order_form.html"></a>

<input type="submit" name="submit" style="background-color:#FF0000" value="  I change my order" onClick="location.href='order_form_table.php'">

Thank you.

you have to check its number with modulus:


if(!empty($_POST["value"]))
{
$b=6;
$a=(int)$_POST["value"];
if(  ($a % $b) ==0 )
echo "ok";  	//Modulus  	Remainder of $a divided by $b.
else
echo "not   ok";
}

Super! Everything working fine with one value.
Nice to get to known to Modulus.

Just one more problem: if I have two or more values, and one of the value is not a multiple of 6, the answer script should echo "not ok" without echoing the other correct value.
See the example at:

http://www.paolinet.info/test_order/order_form_table.php

The form script is :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Untitled Document</title>
</head>

<body>
<?php
session_start();
echo "<form name=\"aaaa\" method=\"post\"  action=\"order_table.php\">";
?>
<table width="457" border="1">
  <tr>
    <td width="125" align="center" valign="top">#image1#</td>
    <td width="125" align="center" valign="top">
<input name="quantity1" type="text" value="<?php echo (!empty($_SESSION["quantity1"]) ? htmlspecialchars($_SESSION["quantity1"]):"" ) ; ?>"></td>
    <td width="125" align="center" valign="top">item1 for 10$</td>
  </tr>
  <tr>
    <td width="125" align="center" valign="top">#image2#</td>
    <td width="125" align="center" valign="top">
<input name="quantity2" type="text" value="<?php echo (!empty($_SESSION["quantity2"]) ? htmlspecialchars($_SESSION["quantity2"]):"" ) ; ?>"></td>
    <td width="125" align="center" valign="top">item2 for 15$</td>
  </tr>
</table>
<br /><input name="submit" type="submit" value="order">
</body>
</html>

The response script is:

<?php
session_start();  

$_SESSION['quantity1'] = $_POST['quantity1'];
$_SESSION['quantity2'] = $_POST['quantity2'];
?>

<?php
if(!empty($_POST["quantity1"]))
{
$b=6;
$quantity1=(int)$_POST["quantity1"];
if(  ($quantity1 % $b) ==0 )
echo "you ordered $quantity1 item1 .<br />";  	//Modulus  	Remainder of $a divided by $b.
else
echo "not   ok.<br />";
}
if(!empty($_POST["quantity2"]))
{
$b=6;
$quantity2=(int)$_POST["quantity2"];
if(  ($quantity2 % $b) ==0 )
echo "you ordered $quantity2 item2 .<br />";  	//Modulus  	Remainder of $a divided by $b.
else
echo "not   ok.<br />";
}

?>

<input type="submit" name="submit" style="background-color:#00CC66" value="  I confirm my order" onClick="location.href='confirm.php'">



<a href="order_form.html"></a>

<input type="submit" name="submit" style="background-color:#FF0000" value="  I change my order" onClick="location.href='order_form_table.php'">

How would you change the response script? Thank you.

<?php
if(!empty($_POST["quantity1"]))
{
$b=6;
$quantity1=(int)$_POST["quantity1"];
if(  ($quantity1 % $b) ==0 )
$message[]= "you ordered $quantity1 item1 .<br />";      //Modulus      Remainder of $a divided by $b.
else
$error[]="error 1";
}


if(!empty($_POST["quantity2"]))
{
$b=6;
$quantity2=(int)$_POST["quantity2"];
if(  ($quantity2 % $b) ==0 )
$message[]= "you ordered $quantity2 item2 .<br />";      //Modulus      Remainder of $a divided by $b.
else
$error[]="error 2";
}


if!empty($empty))
{
die( implode( " " , $error));
}
else
print implode( " " , $message);
?>

i go to sleep now, good luck with the entire code 🙂

What means this warning?

Warning: implode() [function.implode]: Invalid arguments passed in /var/www/web49/html/test_order/order_table.php on line 35

djjjozsi

the if condition did not get the right syntax, try this.

if(!empty($empty))
{
die( implode( " " , $error));
}
else
print implode( " " , $message);

you should build an error array if quentity1 or quanttity2 empty.

I have already noticed last night this missing syntax but the server still sends the following message:

warning: implode() [function.implode]: Invalid arguments passed in /var/www/web49/html/test_order/order_table.php on line 35

If I click on the link "function.implode" I get the following message:

Not Found
The requested URL /test_order/function.implode was not found on this server.

I suppose that there should be a file named "function.implode" on the server but there isn't.

djjjozsi

that was a bit late for thinking for me 🙂

<?php

if ( !empty( $_POST["quantity1"] ) ) {
    $b = 6;
    $quantity1 = ( int )$_POST["quantity1"];
    if ( ( $quantity1 % $b ) == 0 )
        $message[] = "you ordered $quantity1 item1 ."; //Modulus      Remainder of $a divided by $b.
    else
        $error[] = "error with item1";
}

if ( !empty( $_POST["quantity2"] ) ) {
    $b = 6;
    $quantity2 = ( int )$_POST["quantity2"];
    if ( ( $quantity2 % $b ) == 0 )
        $message[] = "you ordered $quantity2 item2 ."; //Modulus      Remainder of $a divided by $b.
    else
        $error[] = "error with item2";
}

if ( !empty( $error ) ) {
    die( implode( "<br />" , $error ) );
} else {
    if ( isset( $message ) )
        print implode( "<br />" , $message );
}

?>

Many thanks, it works. I wait before closing this thread, maybe I'll have another idea and need your help.
Is it possible to rate your excellent help?

if you find that this thread is a super truper new solution for an unknown problem till now, you can add a mark with the select box:
'If you like, you can add a score for this thread.'

in my opinion this is a basic task 🙂

about new questions in the same thread:
worth opening a new topic for a newer question, not to confuse the beginners with a double question who can't coop with a problem like this.
