PHP with html form elements to an order page

[txguy]

Hello and thanks. have a html form with 1210 checkboxes that define item description, number and price. would like to find a PHP script that reads these values when the checkbox is checked and then creates and displays a pre-filled order form with Item number, description, unit price and adds a text box where the user can select quantity.

each item checkbox data looks like this ...

 
<input type="checkbox" name="C04001" id="C04001" value=1 descrip="size, color, partnum,  weight,  class,  texture, hardware" item="04001" rice="4.97" onclick="totalCheckboxes(this);" readonly>
 
 

we are totaling checkboxes on page one and may use a form mailer to track interest, but we really need the second page running on our web server.

thanks again for your help.

Heya, txguy.

When a checkbox is submitted with form data, it will not show up at all if it is unchecked, and it will be included with a value of 'ON' if it is checked.

Probably your best bet would be to create a sub-array and then loop through it:

<!-- --------------------------¬             -->
<input type="checkbox" name="parts[C04001]" id="C04001" value=1 descrip="size, color, partnum,  weight,  class,  texture, hardware" item="04001" rice="4.97" onclick="totalCheckboxes(this);" readonly="readonly" />
 

Then in your PHP:

foreach( $_POST['parts'] as $name => $checked )
{
    // Output / Processing goes here.
 
    // Debug
    echo $name, '<br />';
}

adding the element name change to htm page one works ok, and I have created a html page two with the following php ...

 
<?php 
 
$Item=$_GET["item"];
$Description=$_GET["descrip"];
$UnitPrice=$_GET["price"];
$SubTotal=$_GET["AllColstotal"];
 
foreach( $_POST['parts'] as $name => $checked )
{
 
    // Output / Processing goes here.
 
<!--- ORDER FORM --->
 
}
 
?>
 
 

but it doesnt post from page one.

how should the submit line read on page one??

[pbmods]

Heya, TX.

You'll need to make sure that each checkbox is named properly:

<input type="checkbox" name="parts[C04001]" ... />
<input type="checkbox" name="parts[C04002]" ... />
.
.
.
 

For more information, have a look at this document.

[txguy]

got that part thanks ... I have updated all pageone names to include "parts[xxxxx] and have page one is working fine ... I've built page two with the php code in the top with the table layout and input field names using the $name and the loop function you recommended ... I've saved this file as both name.php and name.htm neither or working ... my form instruction on page one and my submit are as follows ...

 
<form action="pop.php"method="post">
    and also tried it this way
<form action="pop.htm"method="post">
 
<input type="submit">
 
 

why wont the submit button call page two????????


thanks

Heya, TX.

What do you want your code to do? Give an example.
What is your code doing that you don't want it to do? Give an example.
What is your code *not* doing that it is supposed to? Give an example.

[txguy]

when I try

 
<?php
   echo $_POST['descrip'];
   echo $_REQUEST['price'];
 
import_request_variables('p', 'p_');
   echo $p_descrip;
 
 
?>
 

all I get is the form with no data.
thanks

[pbmods]

Heya, TXGuy.

Try this:

print_r($_POST);
 

to see what, if any, input you're getting from the form.

[txguy]

with the following as my second page ...

<?php
$descrip = $_POST['descrip'];
$price = $_POST['price'];
 
echo $descrip, '<br />';
 
print_r($_POST);
 
import_request_variables('p', 'p_');
   echo $p_descrip;
 
echo "You ordered ". $descrip . " " . $price . ".<br />";
echo "WOOHOO!";
 
?>

I get the java produced totals from page one

Array ( [AllColscount] => 1 [selections] => Tarps [AllColstotal] => $ 68.77 [Col01count] => 0 [Col02count] => 0 [Col03count] => 0 [Col04count] => 0 [Col05count] => 0 [Col06count] => 0 [Col07count] => 1 [Col08count] => 0 [Col09count] => 0 [Col10count] => 0 [C07079] => 1 [Col01total] => 0.00 [Col02total] => 0.00 [Col03total] => 0.00 [Col04total] => 0.00 [Col05total] => 0.00 [Col06total] => 0.00 [Col07total] => 68.77 [Col08total] => 0.00 [Col09total] => 0.00 [Col10total] => 0.00 [AllColscountsum] => 1 [AllColstotalsum] => $ 68.77 [view_x] => 26 [view_y] => 11 ) You ordered .
WOOHOO! 
 

none of the checkbox data, checked or unchecked is coming thru

?????

[pbmods]

Heya, TX.

$_POST is not persistent. Your checkbox data will only be available to the page you're submitting the form to.

Try adding this to the top of your first page:

session_start();
foreach( $_POST as $_key => $_val )
{
    $_SESSION[$_key] => $_val;
}
 

And at the top of page two:

session_start();
print_r($_SESSION);
 

[txguy]

got the following

Parse error: syntax error, unexpected T_DOUBLE_ARROW on line 9

<html>
<head>
 
 
<?php
session_start();
foreach( $_POST as $_key => $_val )
{
    $_SESSION[$_key] => $_val;
}
?>

Oops. Sorry about that. Try this:

<html>

<?php
session_start();
foreach( $_POST as $_key => $_val )
{  //  No > here ----¬
    $_SESSION[$_key] = $_val;

?>

Heya, TX.

My goodness. I feel so silly making all of these mistakes that I should know better!

session_start() has to go before your script outputs anything. You'll want to do this instead, and this time, it really should work :P

<?php
session_start();
foreach( $_POST as $_key => $_val )
{
    $_SESSION[$_key] = $_val;
}
?>
<html>
<head>
.

thanks, page1 works but get the following from page2 ...

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/ihh-2693/it-happens-here-www/test/st/popchecks.php:3) in /home/ihh-2693/it-happens-here-www/test/st/popchecks.php on line 5

here's page2 code

<html><body>
 
<?php
 
session_start();
 
print_r($_SESSION);
 
print_r($_POST);
 
?>
 
</body></html>
 

I really appreciate your help

[txguy]

if I delete the

session_start();
 

from page2, I dont get the session error, but I still dont get the input data element from page1 just the array totals from page1

Array ( [AllColscount] => 1 [selections] => Tarps [AllColstotal] => $ 149.39 [Col01count] => 0 [Col02count] => 0 [Col03count] => 0 [Col04count] => 0 [Col05count] => 1 [Col06count] => 0 [Col07count] => 0 [Col08count] => 0 [Col09count] => 0 [Col10count] => 0 [C05079] => 1 [Col01total] => 0.00 [Col02total] => 0.00 [Col03total] => 0.00 [Col04total] => 0.00 [Col05total] => 149.39 [Col06total] => 0.00 [Col07total] => 0.00 [Col08total] => 0.00 [Col09total] => 0.00 [Col10total] => 0.00 [AllColscountsum] => 1 [AllColstotalsum] => $ 149.39 [view_x] => 22 [view_y] => 3 )

????????

Heya, TX.

Similarly to page 1, on page 2, you have to call session_start() before your script outputs anything.

[txguy]

eliminated the html code, just php and I only get the original array values for the total functions from page1, stil dont get the checkbox element values; descrip, price, name

Heya, TX.

A similar problem came up in this thread.
