Adding an IF to post on a checkbox form

Mal1 · February 29, 2012

Trying to fix existing some code (complete beginner here) on the company I work for website.

There's a check-box which when ticked should apply delivery charges and if not it shouldn't - currently it's working in that on the same page it calculates the total cost correctly when checked or not checked but when passing on information it always passes on the delivery charge even if un-ticked...

The simplest thing I can see would be to put an if statement in to say if (not ticked) then del_charges = 0.00. Any idea how I can do this in this instance?

<?php
      // add a checkbox for delivery charges
		echo '<span class="form"><label>Delivery Charges</label>';
      echo '<input type="checkbox" name="del_charges" id="del_charges" value="1" class="boxes" ';
      if ( isset($_POST['del_charges']) && !empty($_POST['del_charges']) )
        echo 'checked="checked"';
      echo '/>';                 
?>

Thanks.

        //do whatever you need to do here to remove the delivery charge

      echo '/>';                 
?>

Thanks, so it's probably a case of fixing what calculates $del_charges earlier on in the code? Or can I do something like: $_POST['del_charges' = 0.00];?

I have no clue how this code is set up.. :psychic:

I highly doubt that re-defining a $_POST value is the best way to go about this.

But without seeing the entire relevant code, I cannot give a better answer.

This is the code from this page. I'm more concerned with how it passes it on to other pages. I have view order and view invoices sections where delivery is being displayed - when that checkbox is not ticked the delivery should be 0 on these but right now it always shows the calculated delivery. This is a manual order - there's another section elsewhere where a customer can select 'collect from store' I've been able to use code to say if collect_from_store == '1' then delivery = 0. I'm looking to do the same thing if this checkbox is not checked...

$action = 'manual_order';
$_SESSION['action'] = $action;

//echo "<pre>";
//print_r($_SESSION); 
//echo "</pre>";
//echo "<pre>";

//echo "</pre>";

By that I mean I've tried adding a field: "manual_del" to the database but not sure how to link up the checkbox being checked or not to the database.
