Checkbox same name, different value problem

[domdeez]

I've set up a simple multi-page form. I am passing the form data from page to page using hidden fields. I do so by adding the piece of code listed below between the form tags of the receiving page.

 

<?php

  foreach($_POST as $key=>$value){

    if ($key!="submit"){

      $value=htmlentities(stripslashes(strip_tags($value)));

      echo "\t<input type=\"hidden\" name=\"$key\" value=\"$value\">\n";

    }if (is_array($value)) {

$value = implode(",",$value);

}

  }

 

 

?>

 

Here's the problem. On the first page there are checkboxes with the same name but different values.  The hidden fields that appear on page 2 only show the first value of this checkbox (when multiple boxes are selected).  I've seen solutions like this below, but haven't found a way to get them to work with the code above.  Can someone point me in the right direction?  Thanks.

 

Retrieving Multiple Checkbox Values As An Array If brackets are missing on names;

 

...

<INPUT TYPE="checkbox" NAME="s" VALUE="A" CHECKED>Checkbox 1<BR>

<INPUT TYPE="checkbox" NAME="s" VALUE="B">Checkbox 2<BR>

<INPUT TYPE="checkbox" NAME="s" VALUE="C">Checkbox 3<BR>

...

processing script

 

<?php

echo '<PRE>('.(gettype($_POST['s']).') ';

print_r($_POST['s']);

?>

will produce:

 

(string) A

 

But if you add [] after each element’s name,

 

...

<INPUT TYPE="checkbox" NAME="s[]" VALUE="A" CHECKED>Checkbox 1<BR>

<INPUT TYPE="checkbox" NAME="s[]" VALUE="B">Checkbox 2<BR>

<INPUT TYPE="checkbox" NAME="s[]" VALUE="C">Checkbox 3<BR>

...

the same PHP code will produce the output below:

 

(array)

Array (

    [0] => A

    [1] => B

    [2] => C

)

Why wouldn't you just use sessions?

 

By the way this line,

$value=htmlentities(stripslashes(strip_tags($value)));

 

Is ridiculous use this,

 

$value=htmlspecialchars($value, ENT_QUOTES);

Thanks for the response.  I'll see if I can work it out using sessions.  New to PHP.

keep the [] in the form makes it easier to process

 

[] will return an array, and the function u posted will handle numerics or strings

 

so build a function

 

function createhidden($post,$inp='')
{
   foreach($post as $key => $val)
   {
       if(is_array($val)) createhidden($val,$key);
       else {
        $val=htmlentities(stripslashes(strip_tags($val)));
         echo '<INPUT TYPE=HIDDEN name="' . (!empty($inp)?"$inp\[\]":$key) . "\" VALUE=\"$val\">\n";
   }
}

 

notice it calls itself on arrays

 

so ya can call it up as

 

 

createhidden($_POST);
