[SOLVED] Dynamic Form posting values for processing

[nostrodamned]

Hi all,

 

I have a form which creates checkboxes dynamically.

 

This is the code for the checkbox generation

<div class="column">
        <?php
$dir = "pdfs/";
$dh = opendir($dir);
echo $file;
$tindex="-2";
while (($file = readdir($dh)) !== false) {
$tindex++;
if($file=='.') continue;
  if($file=='..') continue;
echo "<input id=\"id_$file\" name=\"name_$file\" type=\"checkbox\" class=\"field checkbox\" value=\"$file\" tabindex=\"$tindex\" checked=\"checked\" />
          <label class=\"choice\" for=\"Field101\">$file</label>
          ";

}

closedir($dh);

?>
          
        </div>

 

So what i need to do now is somehow on the page (processfiles.php - defined in the form action)that the gets the post values is something like this

i used $file in each of the parameters - but thats not really necessary I just need the $file as the value of the checkbox that gets posted.

 

For each checkbox value start processing this code then when done bounce back to the form page with with a url value  processing=done.

 

Does that make any sort of sense!!

use an array as the checkbox name i.e.

 

<input name="items[]" type="checkbox"

 

Then in your processing you can loop through the array and process the values.

Hi I tried changing that but it just output the [] and didnt create an array value?

and what would i do on the processing page - can you give me a code hint please!!

You must be doing it wrong. Example

 

<input name="items[]" type="checkbox" value="1" />
<input name="items[]" type="checkbox" value="2" />
<input name="items[]" type="checkbox" value="3" />

// Processing part

foreach($_POST['items'] as $item) {
  // do something with the selected item
}

oh sorry so the outputted html should be <input name="items[]" type="checkbox" value="3" />

not items[1] or something like that? I will give it a go!

Thanks
