Re: [support] Tableselect in forms issue

Hi All Thanks a lot for the input.

I am little bit confused with* $index *stuff. When I add tableselect element, I use the key "*['category_boundary']['category_fieldset']['catg']*" . Somewhere deep in form code, for every row's checkbox, what index is used by form.inc I really do not know. So instead of *$index* what I should use, I am not sure.

Tried to debug more. When I am trying to add rows (means *none* of the rows were selected), if I print the array using dpm(), I get below output.

... (*Array, 4 elements*)

- 0 (*Integer*) *0* - 1 (*Integer*) *0* - 2 (*Integer*) *0* - 3 (*Integer*) *0*

When I am tying to delete rows (means one or more rows were selected, in this particular case I had selected rows 2, 3 and 4), if I print the array * $form_state['values']['category_boundary']['category_fieldset']['catg'] * using dpm(), I get below output, ... (*Array, 4 elements*)

- 1 (*String, 1 characters *) *1* - 2 (*String, 1 characters *) *2* - 3 (*String, 1 characters *) *3* - 0 (*Integer*) *0*

Thats the reason, thought of taking *$index* as key where $index can be one of 0,1,2,3.

Using the logic mentioned in my first email, I will be able to delete the rows 2, 3 and 4. But the problem is if I try to delete the 1st row it does not get deleted. I tried to print the array, it looks as below.

... (*Array, 4 elements*)

- 0 (*String, 1 characters *) *0* - 1 (*Integer*) *0* - 2 (*Integer*) *0* - 3 (*Integer*) *0*

Since irrespective of fact, 0th row is selected or not, always value is 0. Thats the reason, why logic (*if($form_state['values']['category_boundary']['category_fieldset']['catg'][$index]

0. *) does not work.

But from above prints, one thing is clear while I have selected 0th row, 0th element is 0 (*String, 1 characters *) *0* and when 0th row is not selected, it looks as 0 (*Integer*) *0* , (please note the difference here) hence, there should be someway to determine if 0th row is selected or not. I am not a PHP expert , so probably missing something here.

Can somebody kindly help here, how do I determine if the 0th row is selected or not.

Shouldn't it be greater equal zero to get the first element?

Seems like it should work provided you really meant $index to be $key. That’s not in your real code, right? If it is in your cod that way, that’s the bug. ****

Hi All****

I am trying to use tableselect in forms as per below code.****

---

• $form['category_boundary']['category_fieldset']['catg'] = array ( '#type' => 'tableselect', '#header' => $header, '#options' => $options, '#multiple' => TRUE, '#js_select' => FALSE, );*****

By manipulating options array, I can add the rows in forms table.****

---

Sometimes I need to remove the selected rows from form table.****

My question is, how can I determine if a particular row is selected.****

---

Currently using below code to determine which row is selected.****

---

foreach($form_state['values']['category_boundary']['category_fieldset']['catg'] as $key => $value) {

if($form_state['values']['category_boundary']['category_fieldset']['catg'][$index]

...

    {
           //row is selected.
    }
    else
   {
             //row is not selected.
    }
}*****

---

I can determine all the rows if those are selected or not except the 0th row.****

Can somebody tell me, what is the RIGHT way to determine if a particular row in a table is selected or not.****

---

Best Regards****

Kamal****
