PHP - Passing Array Via Url / Get

I have the registration form blues!

form 1 collects the classes chosen, and passes an array of classes chosen(on a previous page), in a hidden field:
<input type="hidden" value="<?= $c_row['workshop_id'] ?>" name="wid[]" />

form 2  makes it a variable $wid = $_POST['wid'];
I'm trying to pass it to form 3, using the hidden input again, this time as a variable:

$wid = $_POST['wid'];
<input type="hidden" value="<?= $wid ?>" name="wid[]" />

The next page is a printable page. But I can't do anything with the classes, because it's some how made an array of an array???
I wrote:  $wid = $_POST['wid'];
 print_r($wid);

This produces---  Array ( => Array )

I want it to give me the original array? Is there a different way to do this?

Okay heres the problem.
I have a form which displays items that sit within a packet. (In this case its called Wireless Package 1). Each item has its own specific value, which can be any string, hench why there is an 'input type= text' in the value column in the table.
Each of these values is stored in a table, with the primary key 'piid', (show as a hidden field within 3rd column).

The problem is when im posting the array 'values[]' I cant distinguish between what value needs to be referenced againist a piid, how do i obtain these individual ID's and Values in a loop so they can turned into a MySql Strings?????

I tried using an explode function but got no where, any help is very much apprieciated!

This is the code for the form displayed.

   <table border="1" cellpadding="5" cellspacing="5">
                     <tr>
                               <th>Item ID</th>
                        <th>Item</th>
                        <th>Value</th>
                                <th>Remove</th>
                     </tr>
<form action="edit_packet.php" method="post">
                     <?php foreach($packages as $packet):?>

                              <tr>
                                              <td>
                                    <?php echo $packet['piid'] ;?>
                                    </td>
                                    <td>
                                    <?php echo $packet['desc'] ;?>
                                    </td>
                                               
                                    <td>
                                                <input type="hidden" name="values[]" value="<?php echo $packet['piid'];?>,," />
                                                <input type="text" name="values[]" value="<?php echo $packet['value']; ?>" />
                                                <input type="hidden" name="values[]" value="///" />

                                                                                                </td>             
                                                                               
                                              <td>
                                       <form action="delete.php" method="post">
                                       <input type="hidden" name="pid" value="<?php echo $packet['piid'];?>"/>
                                       <input type="submit" value="Delete Packet">
                                       
                                 </td>                                             
                              </tr>
                  <?php endforeach; ?>
                       
         </table>
        <input type="submit" value="Submit"  />
                        </form>

I have an issue with a form where people choose from several classes, and how many people they're enrolling. If they choose the first class, select the number of students and hit submit, it is supposed to carry the number of students to the 2nd page where a variable is created for it:
$qty = $_POST['participantqty'];

It works if they pick the first class and choose a number of students.
It works if they pick the first class and another, plus the number of students for each.

But if they choose any one class except the first one (and only that class), choose their number of students and submit...
This is when it doesn't carry the number forward...

It also glitches when they select two classes that don't include the first class. It carries the number of students for one, but not the other.

qty_insert and qty_total on page two are where the data dissappears. I'm assuming it has something to do with the array, but I'm in a little over my head.

On the second page, I added in print_r($myarray); and it shows the variable is passing to the second page.

page one:
Code: [Select]

<form method="post" action="register2.php">

 <? //output each row

  while ($c_row = mysql_fetch_array($result_all_events)){
$display = date("F j", strtotime($c_row['workshop_date'])) ;
$i++;
//date('d m y', strtotime($mysql_date));


    ?>
 
<input type="checkbox" name="workshop_id[]" value="<?= $c_row['workshop_id'] ?>" /> <?= $c_row['workshop_title'] ?> </td><td><?= $c_row['workshop_date'] ?></td><td><select name="participantqty[]" id="" class="">
<option value="">select</option>
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
  <option value="6">6</option>
  <option value="7">7</option>
  <option value="8">8</option>
  <option value="10">9</option>
  <option value="10">10</option>
</select>
$ <?= $c_row['workshop_price'] ?></td></tr><tr><td colspan=3><hr></td></tr>


  <?

  } //end while
  ?>

<input type="submit" value="Submit" class="buttontype">


and on page two where it totals things up:

Code: [Select]

I am passing an array to an option list but if a value has two words, the second word doesnt get sent via POST. So if the value should be THE ONE, the word ONE doesnt get sent via POST. Kinda wierd, wondered if there is an easy explanation for this?

<?php echo '<SELECT name=carrier>';

foreach ($allcar as $key => $value) {
    echo '<OPTION value=' . $value . '> ' . $value . '';

echo '</select>'; ?>

Hi guys,

Is there an html code that allows you to array a form input?

and once you passed the form, how do you extract the data then insert it to the database?

Thanks

i created an array like this

while{
$ir = 0;
$stud[$row_mrk['id_sub']][$ir]=$row_mrk['id_sub']; $ir++;
$stud[$row_mrk['id_sub']][$ir]=$row_mrk['seminar_topic']; $ir++;
$stud[$row_mrk['id_sub']][$ir]=$row_mrk['seminar_mark']; $ir++;
$stud[$row_mrk['id_sub']][$ir]=$row_mrk['attendance']; $ir++;
$stud[$row_mrk['id_sub']][$ir]=$row_mrk['internal_mark']; $ir++;
$stud[$row_mrk['id_sub']][$ir]=$row_mrk['external_mark']; $ir++;
}

echo "<input type='hidden' name='ar_std' id='ar_std' value='$stud' /> </table>" ;

and it is able to print in the same page using

foreach ($stud as $v1) {
echo "$v1\n<br>";
foreach ($v1 as $v2) {
echo "$v2\n<br>";
}
}

and in the next page

$ar_stud[]=$_POST["ar_std"];

I'm getting an error

And here is the page that the user information is supposed to be passed to:

$duration = $_POST["duration['.$row['Name'].']"];
echo '<h1>Added Activities</h1>';
echo $duration;
?>


Well, this isn't working for me. The second page code returns this error:


Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING


When I execute print_r, the values are returned to me. So I have two questions:

1) What do I need to do to change the code on the 2nd page to echo and POST the array?

2)The database contains multiple exercises under the same name. So, when the variables are passed to the 2nd page. All the values are returned regardless of whether they have been filled out or not. What can be done to only returned the user input and not the blank variables?

Hi all

Basically, I have a form which when done will calculate a quote for turf for given areas. Basically each time the user specifies an area it goes into an array, and they can add as many as they want, but the problem seems to be once submitted and it arrives back into the program, it isn't decoding so the multidimensional array is lost. What am I doing wrong here?

Full code below, thanks in advance

Help

Ok quick run down... I need to pass a variable from one page[form] to another while skipping a page that is in the middle.

The middle page is paypal... after they pay, they are being redirected to a thank you for registering with a email also being sent.
But I need their email from the first page[form].

so what i need to figure out or help is:

1. First page is a form, they enter name, last name, address, email and so on
2. They are redirected to paypal to pay for a service.
3. Are directed back to my site for a email to be sent to them, but I need their email from the first page.

hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped.

NOTE - Please read the information first as it contains important information to understand the problem.

Rules →

• There are 9 Columns(C1,C2,C3,C4,C5,C6,C7,C8,C9) [ Max columns will be 9]

• The number of Rows can vary from 3,6,9,12,15,18 (Max). In this case Number of Rows shall be 12

Number of Rows = No of Tickets (Max Allowed 6) x Rows Per Ticket (Max Allowed 3). Thus, Max Rows can be 18

• Each Row is required to have 4 Blank Spaces and 5 Filled with Numbers

• All numbers available in the Column Array have to be utilized

• This configuration of an shall create a matrix of 9 Columns & 12 Rows (3 x 4 Tickets), which is 108 MATRIX BLOCKS where only a maximum of 60 numbers can be filled out of 108 available blocksrandomly with the above conditions being met 100%.

• The numbers in column must be arranged / sorted in ASCENDING ORDER (For coding logic purpose, as soon as the number is assigned to the new MATRIX MAP use array_shift() or unset() the number so as to avoid repetition

Example - Row 1 and Column 1 shall generate a MATRIX BLOCK - R1C1

Row 3 and Column 7 shall generate a MATRIX BLOCK - R3C7

Matrix Block can also be termed as Matrix Cell for your ease (if needed)

array( "R1"=> array( "C1"=> true, // Means that MATRIX BLOCK R1C1 will be NOT EMPTY "C2"=> false, // Means that MATRIX BLOCK R1C2 will be EMPTY "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> false ), "R2"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> false ), "R3"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> false, "C8"=> false, "C9"=> true ), "R4"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> false ), "R5"=> array( "C1"=> false, "C2"=> false, "C3"=> false, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> true ), "R6"=> array( "C1"=> true, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R7"=> array( "C1"=> false, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R8"=> array( "C1"=> true, "C2"=> false, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R9"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R10"=> array( "C1"=> false, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> false, "C9"=> false ), "R11"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> true, "C9"=> false ), "R12"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ) );

In the above array R stands for Row, C for Column, TRUE/FALSE (Boolean) means that if TRUE a Number can be filled in the resulting MATRIX BLOCK / CELL ( Row[Number]Column[Number] ) else if FALSE the MATRIX BLOCK / CELL shall be EMPTY

The result for the above shall be

PROBLEM : 

I am unable to understand what should possibly be the logic & loop used here for creating a MATRIX ALLOCATION MAP as shown above

I have tried while, foreach & for but unable determine the perfect combination which would meet the conditions.

(Tried all of the above with Nested Loops also)
