[Resolved] Is it impossible...?

[jackiw]

Hi there,

Does anyone have an idea on how I can do this?

I have a form with almost 90 checkboxes separeted in 10 categories, in which each category has 9 checkboxes. Each categories' checkbox has its name as categ_01[] for category one, categ_02[] for category two and so on... untill category ten. Each categories' checkbox has its value as categ_01_01 for checkbox one in category one, categ_01_02 for checkbox two in category one and so on... My questions are:

• How can I check which checkboxes have been selected?
• How can I extract each selected value and associate the value with its local vars, label and price? like:

$categ_01_01_label = 'Book';
$categ_01_01_price = '5.00';

So if the user selected the checkbox categ_01_01 for example, it should print "Book - 5.00"

Any idea?

Yes, it's possible. 😃

Only the values of the checked check boxes actually get posted. So start with something like:

function process_checkbox($name)
{
  /* Get the check box array */
  $boxes = $_POST[$name];
  if ($boxes === null) return;

  /* Cycle through values */
  foreach($boxes as $box)
  {
    /* Here is the posted value */
    echo $box . <br />;

/* Build the variable names or whatever */
  }
}
process_checkbox('categ_01');
process_checkbox('categ_02');

This should get your started. Once it's working then you can refine it.

no, it's not impossible. it's not even hard, i think....

this might work, but take into consideration that i am still a relative n00b.

<!-- on the form:-->
<input type="checkbox" value="[label]|[price]" name="categ_01[]">[item]
.....

<?php
//and then on the recieving end:
foreach ($_POST['categ_01'] as $checkbox01)
{
    $values = explode("|",$checkbox01);
    echo $values[0]." -- ".$values[1];
}
//etc for other categories

just replace the [item], [label], and [price with the right values

Both codes are good... Thanks.

One more thing, how can I sum all the prices from the selected checkboxes?

Nevermind...

$total += $values[1];
