Question

I have a checkbox coded in HTML, so far everything works, however I need to pass in an array in the name attribute of the checkboxes. I know its easy enough to do when you pass a variable into the name attribute. But for arrays it is proving tricker.

Here is my code:

   <?php // spit out rest of the list
       $permiCheck = array();
       foreach($pList as $value){
        //go into array, get what is needed to pass into the name attribute
        echo '<tr>';

        echo '<td>';
        echo $value['PName'];
        echo '</td>';
        //pass an array in
        $permiCheck['Id'] = $value['Id'];
        $permiCheck['ItemId'] = $value['ItemId'];
        if($value['Id']!=null) {



        ?>
        <td style="text-align:center;"> <input type="checkbox" checked="yes" name="<?php $permiCheck;?>" value="" id="change"></td>

After I have done this I intend to retrieve what was in the array via the POST method for form validation.

Any idea how I can do that, many thanks.

Answer 1

The name of the checkbox element has to be a string, you can however use checkboxes as an array.
i.e.

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

will return

var_dump($_POST)

array
  'checkboxName' => 
    array
      0 => int 1
      1 => int 2

I’m not sure what you’re trying to do, but maybe you could do it this way

<td style="text-align:center;">
    <input type="checkbox" checked="yes" name="<?=$permiCheck['ItemId']?>[]" value="<?=$permiCheck['Id']?>" id="change">
</td>
