In the admin section of a component, i have this form:

enter image description here

I just added the checkboxes in the left following this Joomla API.


$checked    = JHTML::_( 'grid.id', $i, $voter["vid"] );
echo $checked;

And the Delete button shown in picture like that:

$bar->appendButton( 'Link', 'delete', 'Διαγραφή συγκεκριμένων ψήφων', 'index.php?option=com_exnetpolls&deleteit='.$isnotempty.'&gotcha=yo ');

The component isnt mine and the creator didnt use a controller ( every single action is executed in exnetpolls.php file ) so i created a new file getitdeleted.php and in exnetpolls.php i added this code :

exnetpolls.php (first file that getting executed)

if($_GET['deleteit']!="" && $_GET['deleteit']!=NULL){ 

And in getitdeleted.php

defined('_JEXEC') or die('Restricted access');
echo "test";
$cid = JRequest::getVar('cid',array(),'','array');
echo "worked".$_GET['deleteit'];
//code to delete from db

I know the way im using is a bit retarted,but it works except that the:

$cid = JRequest::getVar('cid',array(),'','array');

returns array(0) {}

Altough if i type in my browser :


the var_dump returns : array(1) { [0]=> string(1) "2" }

I also noticed that i could somehow parse the value with jquery using the id of input, but i would like to do that if it was my last option.

<input id="cb15" name="cid[]" value="2278" onclick="Joomla.isChecked(this.checked);" title="Πλαίσιο ελέγχου για τη σειρά 16" type="checkbox">

I tried also to pass the cid[] somehow with the delete button like so:

$bar->appendButton( 'Link', 'delete', 'Διαγραφή συγκεκριμένων ψήφων', 'index.php?option=com_exnetpolls&deleteit='.$isnotempty.'&gotcha=yo&cid[] ');

But it doesnt work.Could a joomla specialist enlight me please on what am i doing wrong here ?

EDIT: forgot to mention that i would like to check before pressing the DELETE button if cid[]==NULL so i can change the value of $isnotempty . when i var_dump the $cid = JRequest::getVar('cid',array(),'','array'); in the file that i create the input, i get again a null array.

  • Do your checkboxes have correct markup? It should be something like <input id="cb0" name="cid[]" value="73" onclick="Joomla.isChecked(this.checked);" type="checkbox"> Commented Jan 14, 2015 at 13:33
  • I allready mention it in the post ;) <input id="cb15" name="cid[]" value="2278" onclick="Joomla.isChecked(this.checked);" title="Πλαίσιο ελέγχου για τη σειρά 16" type="checkbox">

  • Ah sorry missed it. Try to var_dump($_POST) just after echo "test". Is it containing cid array or it is also missing? Commented Jan 14, 2015 at 14:00
  • Seems it is missing : var_dump($_POST)-> array(0) { }

  • Wait , wait because i dont use a method="POST" somewhere. Should i ? My form is like that:<form action="" name="adminForm"> and i use the delete button to do the work. Should i put METHOD="POST" to my form, and make the delete button a submit button that would do the same stuff??

Based on our comments I would suggest that your delete button invokes only GET action. That means all input fields are not processed. Try to use normal <form> with action="post" like:

<form action="<?php echo JRoute::_('index.php?option=com_exnetpolls&deleteit='.$isnotempty.'&gotcha=yo'); ?>" method="post" name="adminForm" id="adminForm">
  • POST:array(3) { ["cid"]=> array(1) { [0]=> string(4) "2273" } I think im gonna cry of joy. After 8 hours im redeemed! You are a lifesaver dude , thank you very much !

    You should have <input type="hidden" name="boxchecked" value="0" /> in your form and this value will be not zero when checkbox is checked. It is updated by onclick="Joomla.isChecked(this.checked);" function. Commented Jan 14, 2015 at 14:42
